Severe TBI is estimated at 73 cases per 100,000 people. The mortality of severe TBI can be reduced if a timely diagnosis and treatment of the injuries are made through prognostic factors. Objective: To determine the prognostic factors related to mortality in severe traumatic brain injury at the Hospital General de Zona No. 46. Material and Methods: Retrospective, cross-sectional and descriptive study in beneficiaries admitted to the Hospital General de Zona (HGZ) No. 46 of the Mexican Institute of Social Security (IMSS by its acronym in Spanish), with a diagnosis of severe TBI;the possible prognostic factors related to mortality of severe TBI were obtained from their records. Measures of central tendency and chi square were used for data analysis. Results: The study sample consisted of 60 subjects diagnosed with severe traumatic brain injury, of which 5 (8%) were women and 55 (92%) were men, and all 60 (100%) patients died. The average age of the sample was 26 with a standard deviation of 9 years. The variables that had a p value less than or equal to 0.05 were: Mydriasis, seizures, Hyperglycemia, Normoglycemia, Hypothermia and Hypotension. This means that these variables were associated with mortality. Conclusion: Statistical significance is demonstrated in prognostic factors of mortality in severe traumatic brain injury with p < 0.05 in the case of mydriasis, seizures, hyperglycemia, normoglycemia, hypothermia and hypotension.展开更多

In these countries the majority of infections occur in early childhood with the corollary of a frequent transition to chronicity and increased risk of liver cancer. For various reasons, these cancers are diagnosed at a late stage, resulting a high mortality rate. The aim of this work was to study survival and prognostic factors in patients with liver cancer in the gastroenterology department at the Yalgado Ouédraogo University Hospital in Burkina Faso. Patients and Methods: it was a cross-sectional, descriptive and analytical study with retrospective collection in the Gastroenterology department at the Yalgado Ouédraogo University Hospital. The collection period was 12 months, from January 1st to December 31st 2023. The study population consisted of all the patients who had been hospitalized in the Gastroenterology department during the period. Any patient in whom the diagnosis of liver cancer was established was included. The diagnosis was established on clinical and paraclinical criteria. Patients hospitalized with another diagnosis were excluded. The data were analyzed by Epi-Info software. Texts, graphs and table have been produced by Word and Excel Software 2016. Quantitative variables were expressed as mean and standard deviation, and qualitative variables as number and percentage. A difference was considered significant when the p-value was less than 5%. Results: During the study period, 339 patients were hospitalized,107 of whom had liver cancer, representing a prevalence of 31.56%. The mean age was 40.56 years. Men were the most affected, with a sex ratio of 4.6. The mean antecedents were alcohol 33.96%, and hepatitis B. The majority (59.43%) of our patients consulted between 1 and 3 months. Seventy percent of patients were under 60 years old. Hepatitis virus B and/or C were found in 89.7% of cases;60.74% of our patients were in stage D of BCLC classification;66.33% had died. The median survival was 2 months, with overall survival at 6 months estimated at 30% and zero at 14 months. In the multivariate cox model, after adjusting for the other covariables, Child-Pugh stage C, BCLC stage D and sex male were statistically associated as prognostic factors of death with Hazar ratios of 2.66;3.75 and 2.21 respectively. Conclusion: Liver cancer is often diagnosed late in our context with a median survival less than 2 months. Viral hepatitis is the main cause so, preventive measures should be taken as well to decrease liver cancer prevalence.展开更多

METHODS： Ninety-six consecutive patients underwent treatment for malignant hilar bile duct tumors during 1995-2005. Of the 96 patients, 20 were initially treated with surgery （n = 2 R0 / n = 18 R1）. In non-operated patients, data analysis was performed retrospectively. RESULTS： Among the 96 patients, 76 were treated with endoscopic transpapillary （ERC, n = 45） and/or percutaneous transhepatic biliary drainage （PTBD, n = 31）. The mean survival time of these 76 patients undergoing palliative endoscopic and/or percutaneous drainage was 359 ± 296 d. The mean survival time of patients with initial bilirubin levels 〉 10 mg/dL was significantly lower （P 〈 0.001） than patients with bilirubin levels 〈 10 mg/dL. The mean survival time of patients with Bismuth stage Ⅱ （n = 8）, Ⅲ （n = 28） and Ⅳ （n = 40） was 496 =1= 300 d, 441 ± 385 d and 274 ± 218 d, respectively. Thus, patients with advanced Bismuth stage showed a reduced mean survival time, but the difference was not significant. The type of biliary drainage had no significant benefidal effect on the mean survival time （ERC vs PTBD, P = 0.806）. CONCLUSION： Initial bilirubin level is a significant prognostic factor for survival of patients. In contrast, age, tumor stage according to the Bismuth-Corlette classification, and types of intervention are not significant prognostic parameters for survival. Palliative treatment with endoscopic or percutaneous biliary drainage is still suboptimal, new diagnostic and therapeutic tools need to be evaluated.展开更多

A total of 115 patients with mCRPC undergoing a docetaxel q3w regimen were enrolled in this study. A survival analysis was performed using the Kaplan-Meier method. Cox proportional hazards models were used to evaluate the prognostic value of all covariates for OS. OS was also analysed after stratifying patients according to the results of multivariate analysis. The median OS for the entire cohort was 17.0 months. The multivariate analysis showed that the prostate-specific antigen doubling time （PSADT）, baseline haemoglobin （Hb） concentration, alkaline phosphatase （ALP） concentration, cycles of chemotherapy and time to castration resistance were independent prognostic factors of OS. According to the presence of PSADT 〈46.3 days and baseline ALP/〉 110 IU 1-1, all patients were divided into three risk groups： low-risk group （no risk factors）, intermediate-risk group （one risk factor） and high-risk group （two risk factors）. Median OSs for patients in low-, intermediate- and high-risk groups were 28.0 months （95% Ch 23.8-32.2）, 21.0 months （95% Ch 18.9-23.1） and 11.0 months （95% Ch 7.6-14.4）, respectively （P〈O.O01）. In conclusion, PSADT, baseline Hb concentration, ALP concentration, cycles of chemotherapy and time to castration resistance were independent prognostic factors of OS in Chinese patients with mCRPC treated with docetaxel. PSADT combined with the baseline ALP concentration could be a useful risk stratification parameter for evaluating survival outcomes.展开更多

METHODS:We retrospectively analyzed the clinical data of 71 consecutive patients diagnosed with T4 gastric cancer and who underwent curative gastrectomy at our institutions.The clinicopathological factors that could be associated with overall survival were evaluated.The cumulative survival was determined by the Kaplan-Meier method,and univariate comparisons between the groups were performed using the log-rank test.Multivariate analysis was performed using the Cox proportional hazard model and a step-wise procedure. RESULTS:The study patients comprised 53 men (74.6%)and 18 women(25.4%)aged 39-89 years (mean,68.9 years).Nineteen patients(26.8%)had postoperative morbidity:pancreatic fistula developed in 6 patients(8.5%)and was the most frequent complication,followed by anastomosis stricture in 5 patients (7.0%).During the follow-up period,28 patients(39.4%)died because of gastric cancer recurrence,and 3(4.2%) died because of another disease or accident.For all patients,the estimated overall survival was 34.1%at 5 years.Univariate analyses identified the following statistically significant prognostic factors in T4 gastric cancer patients who underwent potentially curative resection: peritoneal washing cytology(P<0.01),number of metastatic lymph nodes(P<0.05),and venous invasion(P <0.05).In multivariate analyses,only peritoneal washing cytology was identified as an independent prognostic factor(HR=3.62,95%CI=1.37-9.57)for longterm survival. CONCLUSION:Positive peritoneal washing cytology was the only independent poor prognostic factor for T4 gastric cancer patients who could be treated with potentially curative resection.展开更多

We retrospectively reviewed the clinical records of 32 patients from 1993 to 2017 diagnosed with PTL and included 22 patients for analysis. The Kaplan-Meier method, Log-rank test, and multivariate Cox proportional hazard regression analysis were applied to evaluate progression-free survival （PFS）, overall survival （OS）, and determine prognosis predictors. The median follow-up time was 30 months. Median OS and PFS were 96 months and 49 months, respectively. In univariate analysis, advanced Ann Arbor stage （Ill/IV） （P 〈 0.001）, B symptoms （P 〈 0.001）, and extranodal involvement other than testis （P = 0.001） were significantly associated with shorter OS and PFS. In multivariate analysis, Ann Arbor stage was significantly associated with OS （OR = 11.58, P = 0.049）, whereas B symptom was significantly associated with PFS （OR = 11.79, P = 0.049）. In the 10 patients with the systemic usage of rituximab, bilateral intervention could improve median OS from 16 to 96 months （P = 0.032）. The study provides preliminary evidence on bilateral intervention in testes in the rituximab era and validates common prognostic factors for Chinese PTL patients.展开更多

We assessed the clinical features, prognostic factors, and differences in outcomes related to BMs among patients with different treatments for HCC. METHODS: Forty-three consecutive patients who were diagnosed with BMs from HCC between January 2010 and December 2014 were retrospectively enrolled. The clinical features were identified, the impacts of prognostic factors on survival were statistically analyzed, and clinical data were compared. RESULTS: The median patient age was 54 years; 38 patients were male and 5 female. The most common site for BMs was the trunk (69.3%). BMs with extension to the soft tissue were found in 14 patients (32.5%). Most (90.7%) of the lesions were mixed osteolytic and osteoblastic, and most (69.8%) patients presented with multiple BMs. The median survival after BMs diagnosis was 11 months. In multivariate analyses, survival after BM diagnosis was correlated with Karnofsky performance status (P=0.008) and the Child-Pugh classification (P<0.001); BM-free survival was correlated with progression beyond the University of California San Francisco criteria (P<0.001) and treatment of primary tumors (P<0.001). BMs with extension to soft tissue were less common in liver transplantation patients. During metastasis, the control of intrahepatic tumors was improved in liver transplantation and hepatectomy patients, compared to conservatively treated patients. CONCLUSIONS: The independent prognostic factors of survival after diagnosis of BMs were the Karnofsky performance status and Child-Pugh classification. HCC patients developed BMs may also benefit from liver transplantation or hepatectomy.展开更多

Methods： A retrospective study of 37 patients with primary testicular DLBCL was carried out from November 2003 to May 2012. Their clinical features, survival and prognostic factors were analyzed. Results： During a median follow-up period of 39.8 months （5.4-93.0 months）, the median progression-free survival （PFS） was 26.2 months （95% CI：0-65 months） and the 3-year overall survival （OS） rate was 78.4%. Within the whole cohort, the factors significantly associated with a superior PFS were limited stage （stage Ⅰ/Ⅱ）, lactate dehydrogenase （LDH） ≤245 U/L, international prognostic index （IPI） ≤1, primary tumor diameter 〈7.5 cm, and patients who had complete response （CR） and received doxoruhicin-contained chemotherapy （P〈0.05）. There was a trend toward superior outcome for patients who received combined therapy （surgery/ chemotherapy/radiotherapy） （P=0.055）. Patients who had CR, primary tumor diameter 〈7.5 cm and IPI score ≤1 were significantly associated with longer PFS at multivariate analysis. Conclusions： Primary testicular DLBCL had poorer survival. CR, primary tumor diameter and IPI were independent prognostic factors. The combined therapy of orchectomy, doxorubicin-contained chemotherapy and contralateral testicular radiotherapy （RT） seemed to improve survival.展开更多

METHODSTumor specimens were obtained from 136 patients with pancreatic cancer who had undergone resection without preoperative therapy between January 2000 and December 2013 at the Department of Surgical Oncology, Osaka City University. The resected specimens were analyzed for associations with clinicopathological data, including DCLK1 expression, epithelial mesenchymal transition (EMT) marker expression, and cancer stem cell (CSC) marker expression. Univariate and multivariate survival analyses were performed and we assessed the association between DCLK1 expression and clinicopathological factors, including the EMT marker and CSC marker. RESULTSIn total, 48.5% (66/136) of the pancreatic cancer samples were positive for DCLK1. Patients with DCLK1-positive tumors had significantly shorter survival times than those with DCLK1-negative tumors (median, 18.7 mo vs 49.5 mo, respectively; P < 0.0001). Positive DCLK1 expression correlated with histological grade (P = 0.0290), preoperative CA19-9 level (P = 0.0060), epithelial cell adhesion molecule (EpCAM) expression (P = 0.0235), and the triple-positive expression of CD44/CD24/EpCAM (P = 0.0139). On univariate survival analysis, five factors were significantly associated with worse overall survival: histological grade of G2 to G4 (P = 0.0091), high preoperative serum SPan-1 level (P = 0.0034), R1/2 (P < 0.0001), positive expression of DCLK1 (P < 0.0001) or CD44 (P = 0.0245). On multivariate survival analysis, R1/2 [odds ratio (OR) = 2.019, 95% confidence interval (CI): 1.380-2.933; P = 0.0004] and positive DCLK1 expression (OR = 1.848, 95%CI: 1.2854-2.661; P = 0.0009) were independent prognostic factors. CONCLUSIONDCLK1 expression was found to be an independent prognostic factor and it may play a crucial prognostic role by promoting acquisition of stemness.展开更多

文摘BACKGROUND Duodenal cancer is one of the most common subtypes of small intestinal cancer,and distant metastasis(DM)in this type of cancer still leads to poor prognosis.Although nomograms have recently been used in tumor areas,no studies have focused on the diagnostic and prognostic evaluation of DM in patients with primary duodenal cancer.AIM To develop and evaluate nomograms for predicting the risk of DM and person-alized prognosis in patients with duodenal cancer.METHODS Data on duodenal cancer patients diagnosed between 2010 and 2019 were extracted from the Surveillance,Epidemiology,and End Results database.Univariate and multivariate logistic regression analyses were used to identify independent risk factors for DM in patients with duodenal cancer,and univariate and multivariate Cox proportional hazards regression analyses were used to determine independent prognostic factors in duodenal cancer patients with DM.Two novel nomograms were established,and the results were evaluated by receiver operating characteristic(ROC)curves,calibration curves,and decision curve analysis(DCA).RESULTS A total of 2603 patients with duodenal cancer were included,of whom 457 cases(17.56%)had DM at the time of diagnosis.Logistic analysis revealed independent risk factors for DM in duodenal cancer patients,including gender,grade,tumor size,T stage,and N stage(P<0.05).Univariate and multivariate COX analyses further identified independent prognostic factors for duodenal cancer patients with DM,including age,histological type,T stage,tumor grade,tumor size,bone metastasis,chemotherapy,and surgery(P<0.05).The accuracy of the nomograms was validated in the training set,validation set,and expanded testing set using ROC curves,calibration curves,and DCA curves.The results of Kaplan-Meier survival curves(P<0.001)indicated that both nomograms accurately predicted the occurrence and prognosis of DM in patients with duodenal cancer.CONCLUSION The two nomograms are expected as effective tools for predicting DM risk in duodenal cancer patients and offering personalized prognosis predictions for those with DM,potentially enhancing clinical decision-making.
文摘BACKGROUND Accurate data on the prognosis of bone metastases are necessary for appropriate treatment.Immune checkpoint inhibitors(ICIs)are widely used in the treatment of gene mutation-negative non-small cell lung cancer(GMN-NSCLC).AIM To investigate the prognostic factors in patients with bone metastases from GMNNSCLC following ICI use.METHODS This retrospective cohort study included 45 patients with GMN-NSCLC who were treated for bone metastases from 2017 to 2022 and received chemotherapy after diagnosis.Using Kaplan–Meier curves and Cox proportional hazards models,we evaluated the association between overall survival(OS)and clinical parameters,including serum biochemical concentrations and blood cell count.RESULTS Univariate analysis showed that Eastern Cooperative Oncology Group performance status≤1 and the use of ICIs and bone-modifying agents after bone metastasis diagnosis were significantly associated with a favorable OS.Multivariate analysis revealed that ICI use after bone metastasis diagnosis was signicantly associated with a favorable OS.CONCLUSION ICI use after bone metastasis diagnosis may be a favorable prognostic factor in patients with bone metastases of GMN-NSCLC.Consideration of ICI treatment for bone metastasis and GMN-NSCLC is warranted to establish a more accurate predictive nomogram for patients with bone metastasis.
文摘BACKGROUND The prognostic value of the Systemic Inflammation Response Index(SIRI)in advanced pancreatic cancer is recognized,but its correlation with patients´nutritional status and outcomes remains unexplored.AIM To study the prognostic significance of SIRI and weight loss in metastatic pancreatic cancer.METHODS The PANTHEIA-Spanish Society of Medical Oncology(SEOM)study is a multicentric(16 Spanish hospitals),observational,longitudinal,non-interventional initiative,promoted by the SEOM Real World-Evidence work group.This pilot study sought to analyze the association between weight loss and inflammatory status as defined by SIRI.The cohort stems from a proof-of-concept pilot study conducted at one of the coordinating centers.Patients with pathologically confirmed metastatic pancreatic adenocarcinoma,treated from January 2020 to January 2023,were included.The index was calculated using the product of neutrophil and monocyte counts,divided by lymphocyte counts,obtained within 15 days before initiation chemotherapy.This study evaluated associations between overall survival(OS),SIRI and weight loss.RESULTS A total of 50 patients were included.66%of these patients were male and the median age was 66 years.Metastasis sites:36%liver,12%peritoneal carcinomatosis,10%lung,and 42%multiple locations.Regarding the first line palliative chemotherapy treatments:50%received gemcitabine plus nab-paclitaxel;28%,modified fluorouracil,leucovorin,irinotecan and oxaliplatin,and 16%were administered gemcitabine.42%had a weight loss>5%in the three months(mo)preceding diagnosis.21 patients with a SIRI≥2.3×10^(3)/L exhibited a trend towards a lower median OS compared to those with a SIRI<2.3×10^(3)/L(4 vs 18 mo;P<0.000).Among 21 patients with>5%weight loss before diagnosis,the median OS was 6 mo,in contrast to 19 mo for those who did not experience such weight loss(P=0.003).Patients with a weight loss>5%showed higher SIRI levels.This difference was statistically significant(P<0.000).For patients with a SIRI<2.3×10^(3)/L,those who did not lose>5%of their weight had an OS of 20 mo,compared to 11 mo for those who did(P<0.001).No association was found between carbohydrate antigen 19-9 levels≥1000 U/mL and weight loss.CONCLUSION A higher SIRI was correlated with decreased survival rates in patients with metastatic pancreatic cancer and associated with weight loss.An elevated SIRI is suggested as a predictor of survival,emphasizing the need for prospective validation in the upcoming PANTHEIA-SEOM study.
文摘In this editorial,I comment on the article by Li et al published in the recent issue of the World Journal of Gastrointestinal Surgery in 2023,investigating the role of some novel prognostic factors for early survival after radical resection of liver cancer.Liver cancer is an important burden among Asian and Western popu-lations,despite recent advances in both medicine(from virus eradication to systemic target therapies)and surgery.However,survival after proven radical surgery remains poor,with recurrences being the rule.Many prognostic scores have been developed and validated to select those patients who will best benefit from radical liver surgery,although the final general and oncological outcomes continue to be highly jeopardized.Unfortunately,no single biomarker can resolve all these issues for hepatocellular carcinoma,and it remains to be proven whether some of them main-tain predictive power in the long-term follow-up.In the ongoing era of“preci-sion”medicine,the novel prognostic markers,including immune inflammatory and nutritional indexes could be of great help in better stratify surgical candi-dates.
文摘Introduction: A traumatic brain injury (TBI) is caused by a forceful bump, blow, or jolt to the head or body, or by an object that pierces the skull and interrupts the normal function of the brain. Severe TBI is estimated at 73 cases per 100,000 people. The mortality of severe TBI can be reduced if a timely diagnosis and treatment of the injuries are made through prognostic factors. Objective: To determine the prognostic factors related to mortality in severe traumatic brain injury at the Hospital General de Zona No. 46. Material and Methods: Retrospective, cross-sectional and descriptive study in beneficiaries admitted to the Hospital General de Zona (HGZ) No. 46 of the Mexican Institute of Social Security (IMSS by its acronym in Spanish), with a diagnosis of severe TBI;the possible prognostic factors related to mortality of severe TBI were obtained from their records. Measures of central tendency and chi square were used for data analysis. Results: The study sample consisted of 60 subjects diagnosed with severe traumatic brain injury, of which 5 (8%) were women and 55 (92%) were men, and all 60 (100%) patients died. The average age of the sample was 26 with a standard deviation of 9 years. The variables that had a p value less than or equal to 0.05 were: Mydriasis, seizures, Hyperglycemia, Normoglycemia, Hypothermia and Hypotension. This means that these variables were associated with mortality. Conclusion: Statistical significance is demonstrated in prognostic factors of mortality in severe traumatic brain injury with p < 0.05 in the case of mydriasis, seizures, hyperglycemia, normoglycemia, hypothermia and hypotension.
文摘Background: Hepatitis B infection is a global public health problem especially in developing countries with high prevalence, and liver cancer is its most feared complication. In these countries the majority of infections occur in early childhood with the corollary of a frequent transition to chronicity and increased risk of liver cancer. For various reasons, these cancers are diagnosed at a late stage, resulting a high mortality rate. The aim of this work was to study survival and prognostic factors in patients with liver cancer in the gastroenterology department at the Yalgado Ouédraogo University Hospital in Burkina Faso. Patients and Methods: it was a cross-sectional, descriptive and analytical study with retrospective collection in the Gastroenterology department at the Yalgado Ouédraogo University Hospital. The collection period was 12 months, from January 1st to December 31st 2023. The study population consisted of all the patients who had been hospitalized in the Gastroenterology department during the period. Any patient in whom the diagnosis of liver cancer was established was included. The diagnosis was established on clinical and paraclinical criteria. Patients hospitalized with another diagnosis were excluded. The data were analyzed by Epi-Info software. Texts, graphs and table have been produced by Word and Excel Software 2016. Quantitative variables were expressed as mean and standard deviation, and qualitative variables as number and percentage. A difference was considered significant when the p-value was less than 5%. Results: During the study period, 339 patients were hospitalized,107 of whom had liver cancer, representing a prevalence of 31.56%. The mean age was 40.56 years. Men were the most affected, with a sex ratio of 4.6. The mean antecedents were alcohol 33.96%, and hepatitis B. The majority (59.43%) of our patients consulted between 1 and 3 months. Seventy percent of patients were under 60 years old. Hepatitis virus B and/or C were found in 89.7% of cases;60.74% of our patients were in stage D of BCLC classification;66.33% had died. The median survival was 2 months, with overall survival at 6 months estimated at 30% and zero at 14 months. In the multivariate cox model, after adjusting for the other covariables, Child-Pugh stage C, BCLC stage D and sex male were statistically associated as prognostic factors of death with Hazar ratios of 2.66;3.75 and 2.21 respectively. Conclusion: Liver cancer is often diagnosed late in our context with a median survival less than 2 months. Viral hepatitis is the main cause so, preventive measures should be taken as well to decrease liver cancer prevalence.
文摘AIM： To evaluate the long-term outcome and prognostic factors of patients with hilar cholangiocarinoma. METHODS： Ninety-six consecutive patients underwent treatment for malignant hilar bile duct tumors during 1995-2005. Of the 96 patients, 20 were initially treated with surgery （n = 2 R0 / n = 18 R1）. In non-operated patients, data analysis was performed retrospectively. RESULTS： Among the 96 patients, 76 were treated with endoscopic transpapillary （ERC, n = 45） and/or percutaneous transhepatic biliary drainage （PTBD, n = 31）. The mean survival time of these 76 patients undergoing palliative endoscopic and/or percutaneous drainage was 359 ± 296 d. The mean survival time of patients with initial bilirubin levels 〉 10 mg/dL was significantly lower （P 〈 0.001） than patients with bilirubin levels 〈 10 mg/dL. The mean survival time of patients with Bismuth stage Ⅱ （n = 8）, Ⅲ （n = 28） and Ⅳ （n = 40） was 496 =1= 300 d, 441 ± 385 d and 274 ± 218 d, respectively. Thus, patients with advanced Bismuth stage showed a reduced mean survival time, but the difference was not significant. The type of biliary drainage had no significant benefidal effect on the mean survival time （ERC vs PTBD, P = 0.806）. CONCLUSION： Initial bilirubin level is a significant prognostic factor for survival of patients. In contrast, age, tumor stage according to the Bismuth-Corlette classification, and types of intervention are not significant prognostic parameters for survival. Palliative treatment with endoscopic or percutaneous biliary drainage is still suboptimal, new diagnostic and therapeutic tools need to be evaluated.
文摘This study aims to evaluate the potential value of patient characteristics in predicting overall survival （OS） in patients with metastatic castration-resistant prostate cancer （mCRPC） treated with docetaxel-based thermotherapy. A total of 115 patients with mCRPC undergoing a docetaxel q3w regimen were enrolled in this study. A survival analysis was performed using the Kaplan-Meier method. Cox proportional hazards models were used to evaluate the prognostic value of all covariates for OS. OS was also analysed after stratifying patients according to the results of multivariate analysis. The median OS for the entire cohort was 17.0 months. The multivariate analysis showed that the prostate-specific antigen doubling time （PSADT）, baseline haemoglobin （Hb） concentration, alkaline phosphatase （ALP） concentration, cycles of chemotherapy and time to castration resistance were independent prognostic factors of OS. According to the presence of PSADT 〈46.3 days and baseline ALP/〉 110 IU 1-1, all patients were divided into three risk groups： low-risk group （no risk factors）, intermediate-risk group （one risk factor） and high-risk group （two risk factors）. Median OSs for patients in low-, intermediate- and high-risk groups were 28.0 months （95% Ch 23.8-32.2）, 21.0 months （95% Ch 18.9-23.1） and 11.0 months （95% Ch 7.6-14.4）, respectively （P〈O.O01）. In conclusion, PSADT, baseline Hb concentration, ALP concentration, cycles of chemotherapy and time to castration resistance were independent prognostic factors of OS in Chinese patients with mCRPC treated with docetaxel. PSADT combined with the baseline ALP concentration could be a useful risk stratification parameter for evaluating survival outcomes.

This study was undertaken to assess the effect of combined vascular resection in HCCA patients and to analyze the prognostic factors.
文摘AIM:To investigate the prognostic factors of T4 gastric cancer patients without distant metastasis who could undergo potentially curative resection. METHODS:We retrospectively analyzed the clinical data of 71 consecutive patients diagnosed with T4 gastric cancer and who underwent curative gastrectomy at our institutions.The clinicopathological factors that could be associated with overall survival were evaluated.The cumulative survival was determined by the Kaplan-Meier method,and univariate comparisons between the groups were performed using the log-rank test.Multivariate analysis was performed using the Cox proportional hazard model and a step-wise procedure. RESULTS:The study patients comprised 53 men (74.6%)and 18 women(25.4%)aged 39-89 years (mean,68.9 years).Nineteen patients(26.8%)had postoperative morbidity:pancreatic fistula developed in 6 patients(8.5%)and was the most frequent complication,followed by anastomosis stricture in 5 patients (7.0%).During the follow-up period,28 patients(39.4%)died because of gastric cancer recurrence,and 3(4.2%) died because of another disease or accident.For all patients,the estimated overall survival was 34.1%at 5 years.Univariate analyses identified the following statistically significant prognostic factors in T4 gastric cancer patients who underwent potentially curative resection: peritoneal washing cytology(P<0.01),number of metastatic lymph nodes(P<0.05),and venous invasion(P <0.05).In multivariate analyses,only peritoneal washing cytology was identified as an independent prognostic factor(HR=3.62,95%CI=1.37-9.57)for longterm survival. CONCLUSION:Positive peritoneal washing cytology was the only independent poor prognostic factor for T4 gastric cancer patients who could be treated with potentially curative resection.
文摘BACKGROUND Colorectal cancer(CRC)is one of the most common malignant tumors in China,and the liver is the most common metastatic site in patients with advanced CRC.Hepatectomy is the gold standard treatment for colorectal liver metastases.For patients who cannot undergo radical resection of liver metastases for various reasons,ablation therapy,interventional therapy,and systemic chemotherapy can be used to improve their quality of life and prolong their survival time.AIM To explore the prognostic factors and treatments of liver metastases of CRC.METHODS A retrospective analysis was conducted on 87 patients with liver metastases from CRC treated at the Liaoning Cancer Hospital and Institute between January 2005 and March 2011.According to different treatments,the patients were divided into the following four groups:Surgical resection group(36 patients);ablation group(23 patients);intervention group(15 patients);and drug group(13 patients).The clinicopathological data and postoperative survival of the four groups were analyzed.The Kaplan-Meier method was used for survival analysis,and the Cox proportional hazards regression model was used for multivariate analysis.RESULTS The median survival time of the 87 patients was 38.747±3.062 mo,and the 1-and 3-year survival rates were 87.5%and 53.1%,respectively.The Cox proportional hazards model showed that the following factors were independent factors affecting prognosis:The degree of tumor differentiation,the number of metastases,the size of metastases,and whether the metastases are close to great vessels.The results of treatment factor analysis showed that the effect of surgical treatment was better than that of drugs,intervention,or ablation alone,and the median survival time was 48.83±4.36 mo.The drug group had the worst prognosis,with a median survival time of only 13.5±0.7 mo(P<0.05).For patients with liver metastases of CRC near the great vessels,the median survival time(27.3 mo)of patients undergoing surgical resection was better than that of patients using other treatments(20.6 mo)(P<0.05).CONCLUSION Patients with a low degree of primary tumor differentiation,multiple liver metastases(number of tumors>4),and maximum diameter of liver metastases>5 cm have a poor prognosis.Among drug therapy,intervention,ablation,and surgical treatment options,surgical treatment is the first choice for liver metastases.When liver metastases are close to great vessels,surgical treatment is significantly better than drug therapy,intervention,and ablation alone.
文摘This study aims to investigate the effect of different local testicular treatments and validate common prognostic factors on primary testicular lymphoma （PTL） patients. We retrospectively reviewed the clinical records of 32 patients from 1993 to 2017 diagnosed with PTL and included 22 patients for analysis. The Kaplan-Meier method, Log-rank test, and multivariate Cox proportional hazard regression analysis were applied to evaluate progression-free survival （PFS）, overall survival （OS）, and determine prognosis predictors. The median follow-up time was 30 months. Median OS and PFS were 96 months and 49 months, respectively. In univariate analysis, advanced Ann Arbor stage （Ill/IV） （P 〈 0.001）, B symptoms （P 〈 0.001）, and extranodal involvement other than testis （P = 0.001） were significantly associated with shorter OS and PFS. In multivariate analysis, Ann Arbor stage was significantly associated with OS （OR = 11.58, P = 0.049）, whereas B symptom was significantly associated with PFS （OR = 11.79, P = 0.049）. In the 10 patients with the systemic usage of rituximab, bilateral intervention could improve median OS from 16 to 96 months （P = 0.032）. The study provides preliminary evidence on bilateral intervention in testes in the rituximab era and validates common prognostic factors for Chinese PTL patients.

文摘BACKGROUND: Bone metastases (BMs) from hepatocellular carcinoma (HCC) is an increasingly common disease in Asia. We assessed the clinical features, prognostic factors, and differences in outcomes related to BMs among patients with different treatments for HCC. METHODS: Forty-three consecutive patients who were diagnosed with BMs from HCC between January 2010 and December 2014 were retrospectively enrolled. The clinical features were identified, the impacts of prognostic factors on survival were statistically analyzed, and clinical data were compared. RESULTS: The median patient age was 54 years; 38 patients were male and 5 female. The most common site for BMs was the trunk (69.3%). BMs with extension to the soft tissue were found in 14 patients (32.5%). Most (90.7%) of the lesions were mixed osteolytic and osteoblastic, and most (69.8%) patients presented with multiple BMs. The median survival after BMs diagnosis was 11 months. In multivariate analyses, survival after BM diagnosis was correlated with Karnofsky performance status (P=0.008) and the Child-Pugh classification (P<0.001); BM-free survival was correlated with progression beyond the University of California San Francisco criteria (P<0.001) and treatment of primary tumors (P<0.001). BMs with extension to soft tissue were less common in liver transplantation patients. During metastasis, the control of intrahepatic tumors was improved in liver transplantation and hepatectomy patients, compared to conservatively treated patients. CONCLUSIONS: The independent prognostic factors of survival after diagnosis of BMs were the Karnofsky performance status and Child-Pugh classification. HCC patients developed BMs may also benefit from liver transplantation or hepatectomy.

文摘BACKGROUND Liver cancer has a high mortality and morbidity rate throughout the world.In clinical practice,the prognosis of liver cancer patients is poor,and the complex reasons contribute to treatment failures,including fibrosis,hepatitis viral infection,drug resistance and metastasis.Thus,screening novel prognostic biomarkers is of great importance for guiding liver cancer therapy.Orosomucoid genes(ORMs)encode acute phase plasma proteins,including orosomucoid 1(ORM1)and ORM2.Previous studies showed their upregulation upon inflammation,but the specific function of ORMs has not yet been determined,especially in the development of liver cancer.AIM To determine the expression of ORMs and their potential function in liver cancer.METHODS Analysis of the expression of ORMs in different human tissues was performed on data from the HPA RNA-seq normal tissues project.The expression ratio of ORMs was determined using the HCCDB database,including the ratio between liver cancer and other cancers,normal liver and other normal tissues,liver cancer and adjacent normal liver tissues.Analysis of ORM expression in different cancer types was performed using The Cancer Genome Atlas and TIMER database.The expression of ORMs in liver tumor tissues and adjacent normal tissues were further confirmed using Gene Expression Omnibus data,including GSE36376 and GSE14520.The 10-year overall survival(OS),progression-free survival(PFS)and relapse-free survival(RFS)rates between high and low ORM expression groups in liver cancer patients were determined using the Kaplan-Meier plotter tool.Gene Set Enrichment Analysis(GSEA)was employed to explore the ORM2-associated signaling network.Correlations between ORM2 expression and tumor purity or the infiltration level of macrophages in liver tumor tissues were determined using the TIMER database.The correlation between ORM2 gene levels,tumor-associated macrophage(TAM)markers(including CD68 and TGFβ1)and T cell immunosuppression(including CTLA4 and PD-1)in liver tumor tissues and liver GTEx was determined using the GEPIA database.RESULTS ORM1 and ORM2 were highly expressed in normal liver and liver tumor tissues.ORM1 and ORM2 expression was significantly decreased in liver tumor tissues compared with adjacent normal tissues,and similar results were also noted in cholangiocarcinoma,esophageal carcinoma,and lung squamous cell carcinoma.Further analysis of the Gene Expression Omnibus Database also confirmed the downregulation of ORM1 and ORM2 in liver tumors.Survival analysis showed that the high ORM2 group had better survival rates in OS,PFS and RFS.ORM1 only represented better performance in PFS,but not in OS or RFS.GSEA analysis of ORM2 from The Cancer Genome Atlas liver cancer data identified that ORM2 positively associated with the G2/M checkpoint,E2F target signaling,as well as Wnt/β-catenin and Hedgehog signaling.Moreover,apoptosis,IFN-αresponses,IFN-γresponses and humoral immune responses were upregulated in the ORM2 high group.ORM2 expression was negatively correlated with the macrophage infiltration level,CD68,TGFβ1,CTLA4 and PD-1 levels.CONCLUSION The results showed that ORM1 and ORM2 were highly expressed specifically in liver tissues,whereas ORM1 and ORM2 were downregulated in liver tumor tissues.ORM2 is a better prognostic factor for liver cancer.Furthermore,ORM2 is closely associated with cancer-promoting pathways.
文摘Objective： To assess the clinical features, survival and prognostic factors of primary testicular diffuse large B-cell lymphoma （DLBCL）. Methods： A retrospective study of 37 patients with primary testicular DLBCL was carried out from November 2003 to May 2012. Their clinical features, survival and prognostic factors were analyzed. Results： During a median follow-up period of 39.8 months （5.4-93.0 months）, the median progression-free survival （PFS） was 26.2 months （95% CI：0-65 months） and the 3-year overall survival （OS） rate was 78.4%. Within the whole cohort, the factors significantly associated with a superior PFS were limited stage （stage Ⅰ/Ⅱ）, lactate dehydrogenase （LDH） ≤245 U/L, international prognostic index （IPI） ≤1, primary tumor diameter 〈7.5 cm, and patients who had complete response （CR） and received doxoruhicin-contained chemotherapy （P〈0.05）. There was a trend toward superior outcome for patients who received combined therapy （surgery/ chemotherapy/radiotherapy） （P=0.055）. Patients who had CR, primary tumor diameter 〈7.5 cm and IPI score ≤1 were significantly associated with longer PFS at multivariate analysis. Conclusions： Primary testicular DLBCL had poorer survival. CR, primary tumor diameter and IPI were independent prognostic factors. The combined therapy of orchectomy, doxorubicin-contained chemotherapy and contralateral testicular radiotherapy （RT） seemed to improve survival.
文摘To elucidate the effect of expression of doublecortin and CaM kinase-like-1 (DCLK1) in patients with pancreatic ductal adenocarcinoma (PDAC). METHODSTumor specimens were obtained from 136 patients with pancreatic cancer who had undergone resection without preoperative therapy between January 2000 and December 2013 at the Department of Surgical Oncology, Osaka City University. The resected specimens were analyzed for associations with clinicopathological data, including DCLK1 expression, epithelial mesenchymal transition (EMT) marker expression, and cancer stem cell (CSC) marker expression. Univariate and multivariate survival analyses were performed and we assessed the association between DCLK1 expression and clinicopathological factors, including the EMT marker and CSC marker. RESULTSIn total, 48.5% (66/136) of the pancreatic cancer samples were positive for DCLK1. Patients with DCLK1-positive tumors had significantly shorter survival times than those with DCLK1-negative tumors (median, 18.7 mo vs 49.5 mo, respectively; P < 0.0001). Positive DCLK1 expression correlated with histological grade (P = 0.0290), preoperative CA19-9 level (P = 0.0060), epithelial cell adhesion molecule (EpCAM) expression (P = 0.0235), and the triple-positive expression of CD44/CD24/EpCAM (P = 0.0139). On univariate survival analysis, five factors were significantly associated with worse overall survival: histological grade of G2 to G4 (P = 0.0091), high preoperative serum SPan-1 level (P = 0.0034), R1/2 (P < 0.0001), positive expression of DCLK1 (P < 0.0001) or CD44 (P = 0.0245). On multivariate survival analysis, R1/2 [odds ratio (OR) = 2.019, 95% confidence interval (CI): 1.380-2.933; P = 0.0004] and positive DCLK1 expression (OR = 1.848, 95%CI: 1.2854-2.661; P = 0.0009) were independent prognostic factors. CONCLUSIONDCLK1 expression was found to be an independent prognostic factor and it may play a crucial prognostic role by promoting acquisition of stemness.
文摘BACKGROUND Gastric cancer is the third leading cause of cancer-related death worldwide and surgical resection remains the sole curative treatment for gastric cancer.Minimally invasive gastrectomy including laparoscopic and robotic approaches has been increasingly used in a few decades.Thus far,only a few reports have investigated the oncological outcomes following minimally invasive gastrectomy.AIM To determine the 5-year survival following minimally invasive gastrectomy for gastric cancer and identify prognostic predictors.METHODS This retrospective cohort study identified 939 patients who underwent gastrectomy for gastric cancer during the study period.After excluding 125 patients with non-curative surgery(n=77),other synchronous cancer(n=2),remnant gastric cancer(n=25),insufficient physical function(n=13),and open gastrectomy(n=8),a total of 814 consecutive patients with primary gastric cancer who underwent minimally invasive R0 gastrectomy at our institution between 2009 and 2014 were retrospectively examined.Accordingly,5-year overall and recurrence-free survival were analyzed using the Kaplan–Meier method with the log-rank test and Cox regression analyses,while factors associated with survival were determined using multivariate analysis.RESULTS Our analysis showed that age>65 years,American Society of Anesthesiologists(ASA)physical status 3,total or proximal gastrectomy,and pathological T4 and N positive status were independent predictors of both 5-year overall and recurrencefree survival.Accordingly,the included patients had a 5-year overall and recurrence-free survival of 80.3%and 78.2%,respectively.Among the 814 patients,157(19.3%)underwent robotic gastrectomy,while 308(37.2%)were diagnosed with pathological stage II or III disease.Notably,our findings showed that robotic gastrectomy was an independent positive predictor for recurrence-free survival in patients with pathological stage II/III[hazard ratio:0.56(0.33-0.96),P=0.035].Comparison of recurrence-free survival between the robotic and laparoscopic approach using propensity score matching analysis verified that the robotic group had less morbidity(P=0.005).CONCLUSION Age,ASA status,gastrectomy type,and pathological T and N status were prognostic factors of minimally invasive gastrectomy,with the robot approach possibly improving long-term outcomes of advanced gastric cancer.
