Split liver transplantation(SLT) is a promising way to ameliorate organ shortages. However, the safety and efficacy of SLT are still controversial. The aim of this study was to assess the clinical outcome of SLT in liver cancer patients at our center. METHODS: A total of 74 patients who received liver transplantation at a tertiary hospital from March 2019 to July 2023 were retrospectively studied, of whom 37 recipients underwent SLT and 37 recipients underwent whole-graft liver transplantation(WGLT). Clinical data were analyzed and compared between patients who underwent SLT and WGLT.RESULTS: SLT and WGLT were successfully performed, with no intraoperative transplantrelated mortality. Postoperatively, no significant differences in total bilirubin(TB, P=0.266), alanine transaminase(ALT, P=0.403) and aspartate transaminase(AST, P=0.160) levels within 30 d were detected between the two groups. The transplant-related mortality rates were 8.1% in the SLT group and 5.4% in the WGLT group within 30 d of surgery(P=1.000), and 10.8% and 8.1%, respectively, at 90 d after surgery(P=1.000). There were no significant differences in overall survival(OS) and progress-free survival(PFS) between the SLT and WGLT groups(P=0.910, P=0.190). CONCLUSION: Our results show that SLT does not imply additional risks in treating liver cancer compared with WGLT.展开更多

BACKGROUND Hepatocellular carcinoma(HCC)is the third leading cause of cancer death worldwide,with a 5-year relative survival rate of approximately 18%.The similarity between incidence and mortality(830000 deaths per y...BACKGROUND Hepatocellular carcinoma(HCC)is the third leading cause of cancer death worldwide,with a 5-year relative survival rate of approximately 18%.The similarity between incidence and mortality(830000 deaths per year)underscores the bleak prognosis associated with the disease.HCC is the fourth most common malignancy and the second leading cause of cancer death in China.Most patients with HCC have a history of chronic liver disease such as chronic hepatitis B virus(HBV)or hepatitis C virus(HCV)infection,alcoholism or alcoholic steatohepatitis,nonalcoholic fatty liver disease,or nonalcoholic steatohepatitis.Early diagnosis and effective treatment are the keys to improving the prognosis of patients with HCC.Although the total number of human immunodeficiency virus(HIV)-infected patients is declining globally the incidence of HCC is increasing in HIVinfected patients,especially those who are coinfected with HBV or HCV.As a result,people infected with HIV still face unique challenges in terms of their risk of developing HCC.AIM To investigate the survival prognosis and clinical efficacy of surgical resection in patients with HCC complicated with HIV infection.METHODS The clinical data of 56 patients with HCC complicated with HIV admitted to the Third Affiliated Hospital of Nantong University from January 2013 to December 2023 were retrospectively analyzed.Among these,27 patients underwent hepatectomy(operation group)and 29 patients received conservative treatment(nonoperation group).All patients signed informed consents in line with the provisions of medical ethics.The general data,clinicopathological features and prognoses for the patients in the two groups were analyzed and the risk factors related to the prognoses of the patients in the operation group were identified.RESULTS The median disease-free survival(DFS)and overall survival(OS)of HIV-HCC patients in the surgical group were 13 months and 17 months,respectively,and the median OS of patients in the nonsurgical group was 12 months.The OS of the surgical group was significantly longer than that of the control group(17 months vs 12 months,respectively;P<0.05).The risk factors associated with DFS and OS in the surgical group were initial HIV diagnosis,postoperative microvascular invasion(MVI),a CD4+T-cell count<200/μL,Barcelona stage C-D,and men who have sex with men(MSM;P<0.05).CONCLUSION Hepatectomy can effectively prolong the survival of patients with HIV-HCC but MVI identified during postoperative pathological examination,late tumor detection,late BCLC stage,CD4+T<200/μL and MSM are risk factors affecting the survival and prognosis of patients undergoing hepatectomy.In addition,there were significant differences between the surgical group and the nonsurgical group in terms of the initial diagnosis of HIV,Child-Pugh score,alpha-fetoprotein measurement value,and HART-efficient antiretroviral therapy after the diagnosis of HIV(P<0.05).Therefore,these factors may also affect the survival and prognosis of patients.展开更多

文摘Lung cancer, the leading cause of cancer deaths worldwide and in China, has a 19.7% five-year survival rate due to terminal-stage diagnosis^([1-3]).Although low-dose computed tomography(CT) screening can reduce mortality, high false positive rates can create economic and psychological burdens.
文摘BACKGROUND Pancreatic cancer remains one of the most lethal malignancies worldwide,with a poor prognosis often attributed to late diagnosis.Understanding the correlation between pathological type and imaging features is crucial for early detection and appropriate treatment planning.AIM To retrospectively analyze the relationship between different pathological types of pancreatic cancer and their corresponding imaging features.METHODS We retrospectively analyzed the data of 500 patients diagnosed with pancreatic cancer between January 2010 and December 2020 at our institution.Pathological types were determined by histopathological examination of the surgical spe-cimens or biopsy samples.The imaging features were assessed using computed tomography,magnetic resonance imaging,and endoscopic ultrasound.Statistical analyses were performed to identify significant associations between pathological types and specific imaging characteristics.RESULTS There were 320(64%)cases of pancreatic ductal adenocarcinoma,75(15%)of intraductal papillary mucinous neoplasms,50(10%)of neuroendocrine tumors,and 55(11%)of other rare types.Distinct imaging features were identified in each pathological type.Pancreatic ductal adenocarcinoma typically presents as a hypodense mass with poorly defined borders on computed tomography,whereas intraductal papillary mucinous neoplasms present as characteristic cystic lesions with mural nodules.Neuroendocrine tumors often appear as hypervascular lesions in contrast-enhanced imaging.Statistical analysis revealed significant correlations between specific imaging features and pathological types(P<0.001).CONCLUSION This study demonstrated a strong association between the pathological types of pancreatic cancer and imaging features.These findings can enhance the accuracy of noninvasive diagnosis and guide personalized treatment approaches.
文摘OBJECTIVE The emergence of evolving variants of Coronavirus disease 2019(COVID-19)has fostered the need for change of newer and adaptive treatments for these infections.During the COVID-19 pandemic and persists,traditional Chinese medicine(TCM)herbs exhibit significant bioactivity and therapeutic effect.This study is aimed to evaluate the efficacy of four TCM preparations on 28-day mortality risk of patients and changes of the laboratory indicators.METHODS The retrospective cohort study included patients with COVID-19 who were admitted to the Jiangsu Province Hospital of Chinese Medicine from December 15,2022 to January 15,2023,and those died within 48 hours of admission or cannot be tracked for outcomes were excluded.The primary outcome was survival status in 28 days(death or survival)starting from the day of admission.The second outcomes were laboratory indicators,including absolute lymphocyte count,lactate dehydrogenase,creatinine,and blood urea nitrogen.Binary logistic regressions were used to estimate the effect of TCM preparations on the primary and secondary outcomes in main analysis.Meanwhile,heterogeneity and robustness of results from main analysis were assessed by subgroup analyses and multiple sensitivity analyses.RESULTS 1816 eligible patients were included in analysis dataset,including 573 patients received standard care(control group)and 1243 patients received TCM preparations(hospital preparation group).The 28-day mortality rate of hospital preparation group was lower than that of control group(4.75%vs.14.83%),and the difference was statistically significant(χ^(2)=54.666,P<0.001).The risk of 28-day mortality was 0.535 times lower in the hospital preparation group as compared with the control group(OR=0.46,95%CI:0.305-0.708,P<0.001)showed by multivariable binary logistic regressions.Subgroup analyses showed that taking TCM preparations reduced the 28-day mortality risk.Sensitivity analyses demonstrated that the results of the main analysis for primary outcomes were robust.For secondary outcomes,the risk of abnormal absolute lymphocyte counts at discharge in the hospital preparation group decreased by 0.284 times(OR=0.703,95%CI:0.515-0.961,P=0.027).CONCLUSION Compared with standard of care,taking four hospital preparations including Kanggan Heji,Feining Heji,Qishen Gubiao Keli,and Qianghuo Qushi Qingwen Heji decreased risk of 28-day mortality among hospitalized COVID-19 patients.TCM therapy achieves adequate therapeutic effects in COVID-19.
文摘BACKGROUND Post-hepatectomy portal vein thrombosis(PH-PVT)is a life-threatening complication;however,the available literature on this topic is limited.AIM To examine the incidence,risk factors,and outcomes associated with PH-PVT.METHODS Medical records of patients who underwent hepatic resection for various diseases between February 2014 and December 2023 at Beijing Tsinghua Changgung Hospital affiliated with Tsinghua University(Beijing,China)were retrospectively reviewed.The patients were divided into a PH-PVT group and a non-PH-PVT group.Univariate and multivariate logistic regression analyses were performed to identify the risk factors for PH-PVT.RESULTS A total of 1064 patients were included in the study cohort,and the incidence and mortality rates of PH-PVT were 3.9%and 35.7%,respectively.The median time from hepatectomy to the diagnosis of PH-PVT was 6 days.Multivariate analysis revealed that hepatectomy combined with pancreaticoduodenectomy(HPD)[odds ratio(OR)=7.627(1.390-41.842),P=0.019],portal vein reconstruction[OR=6.119(2.636-14.203),P<0.001]and a postoperative portal vein angle<100°[OR=2.457(1.131-5.348),P=0.023]were independent risk factors for PH-PVT.Age≥60 years[OR=8.688(1.774-42.539),P=0.008]and portal vein reconstruction[OR=6.182(1.246-30.687),P=0.026]were independent risk factors for mortality in PH-PVT patients.CONCLUSION Portal vein reconstruction,a postoperative portal vein angle<100°and HPD were independent risk factors for PHPVT.Age≥60 years and portal vein reconstruction were independent risk factors for mortality in PH-PVT patients.

文摘BACKGROUND: The increasing morbidity of liver cancer has led to a growing demand for transplantation. Split liver transplantation(SLT) is a promising way to ameliorate organ shortages. However, the safety and efficacy of SLT are still controversial. The aim of this study was to assess the clinical outcome of SLT in liver cancer patients at our center. METHODS: A total of 74 patients who received liver transplantation at a tertiary hospital from March 2019 to July 2023 were retrospectively studied, of whom 37 recipients underwent SLT and 37 recipients underwent whole-graft liver transplantation(WGLT). Clinical data were analyzed and compared between patients who underwent SLT and WGLT.RESULTS: SLT and WGLT were successfully performed, with no intraoperative transplantrelated mortality. Postoperatively, no significant differences in total bilirubin(TB, P=0.266), alanine transaminase(ALT, P=0.403) and aspartate transaminase(AST, P=0.160) levels within 30 d were detected between the two groups. The transplant-related mortality rates were 8.1% in the SLT group and 5.4% in the WGLT group within 30 d of surgery(P=1.000), and 10.8% and 8.1%, respectively, at 90 d after surgery(P=1.000). There were no significant differences in overall survival(OS) and progress-free survival(PFS) between the SLT and WGLT groups(P=0.910, P=0.190). CONCLUSION: Our results show that SLT does not imply additional risks in treating liver cancer compared with WGLT.

文摘BACKGROUND Gastric signet-ring cell carcinoma(GSRCC)is a more aggressive subtype of gastric cancer compared to gastric adenocarcinoma(GA),with an increasing incidence.However,the prognostic differences between these subtypes,particularly in re-sectable cases,remain unclear.AIM To evaluate prognostic factors and develop a predictive model for GA and GSRCC patients undergoing curative resection.METHODS This retrospective cohort study included patients with GA and GSRCC who underwent curative surgery at the National Cancer Center/Cancer Hospital,Chinese Academy of Medical Sciences,from 2011 to 2018.Propensity score ma-tching(PSM)(1:1)balanced the baseline characteristics.Prognostic factors were identified using univariate and multivariate Cox and least absolute shrinkage and selection operator(LASSO)regression analyses.Model performance was eva-luated through calibration curves,decision curve analysis(DCA),and time-dependent receiver operating characteristic curves.Subgroup analysis and Ka-plan-Meier survival curves were generated.RESULTS In a cohort of 3027 patients,the GSRCC group was characterized by a significantly higher prevalence of individuals under 60 years of age,females,cases with poor differentiation,and early-stage(stage I)disease(all P<0.001).After PSM,the baseline was balanced and 761 patients were retained in each group.Variables identified through univariate Cox regression were included in the LASSO regression analysis.Mul-tivariate Cox regression analysis identified age,tumor differentiation,tumor size,vascular invasion,and post-treatment nodal margin staging as independent prognostic factors.Subgroup analysis indicated a notably poorer prognosis for GSRCC in patients aged 60 and above(hazard ratio=1.36,P=0.025).The nomogram(C-index=0.755)exhibited greater predictive accuracy than tumor node metastasis(TNM)staging for 1-,3-,and 5-year overall survival(all P<0.001),and provided a higher clinical net benefit according to DCA.CONCLUSION This study systematically compared resectable GA and GSRCC,revealing no overall survival difference.However,GSRCC demonstrated a significantly elevated mortality risk in subgroups stratified by age and tumor size.Multivariate analysis identified age,differentiation,tumor size,vascular invasion,and TNM stage as independent prognostic factors.The nomogram integrates clinicopathological features for precise risk stratification,surpassing traditional TNM staging.
文摘BACKGROUND Endoscopic retrograde cholangiopancreatography is a challenging procedure involving bile duct cannulation.Despite the development of several cannulation devices,none have effectively facilitated the procedure.AIM To evaluate the efficacy of a recently developed catheter for bile duct cannulation.METHODS We retrospectively examined 342 patients who underwent initial cholangiopan-creatography.We compared the success rate of bile duct cannulation and the incidence of complications between the groups using existing and novel catheters.RESULTS The overall success rates of bile duct cannulation were 98.3%and 99.1%in the existing and novel catheter groups,respectively(P=0.47).The bile duct cannulation rate using the standard technique was 73.0%and 82.1%in the existing and novel catheter groups,respectively(P=0.042).Furthermore,when catheterization was performed by expert physicians,the bile duct cannulation rate was significantly higher in the novel catheter group(81.3%)than in the existing catheter group(65.2%)(P=0.017).The incidence of difficult cannulation was also significantly lower in the novel catheter group(17.4%)than in the existing catheter group(33.0%)(P=0.019).CONCLUSION The novel catheter improved the bile duct cannulation rate using the standard technique and reduced the frequency of difficult cannulation cases,valuable tool in endoscopic retrograde cholangiopancreatography procedures performed by experts.
文摘Objective To develop and validate a preoperative clinical-radiomics model for predicting overall survival(OS)and disease-free survival(DFS)in patients with extrahepatic cholangiocarcinoma(eCCA)undergoing radical resection.Methods In this retrospective study,consecutive patients with pathologically-confirmed eCCA who underwent radical resection at our institution from 2015 to 2022 were included.The patients were divided into a training cohort and a validation cohort according to the chronological order of their CT examinations.Least absolute shrinkage and selection operator(LASSO)-Cox regression was employed to select predictive radiomic features and clinical variables.The selected features and variables were incorporated into a Cox regression model.Model performance for 1-year OS and DFS prediction was assessed using calibration curves,area under receiver operating characteristic curve(AUC),and concordance index(C-index).Results This study included 123 patients(mean age 64.0±8.4 years,85 males/38 females),with 86 in the training cohort and 37 in the validation cohort.The OS-predicting model included four clinical variables and four radiomic features.It achieved a training cohort AUC of 0.858(C-index=0.800)and a validation cohort AUC of 0.649(C-index=0.605).The DFS-predicting model included four clinical variables and four other radiomic features.It achieved a training cohort AUC of 0.830(C-index=0.760)and a validation cohort AUC of 0.717(C-index=0.616).Conclusion The preoperative clinical-radiomics models show promise as a tool for predicting 1-year OS and DFS in eCCA patients after radical surgery.
文摘BACKGROUND Gastric cancer(GC)poses a significant threat to public health.However,the clinicopathological features and tumor biological behaviors vary among the GC patients,leading to individual variations in lymph node metastasis.Consequently,the stratification of lymph node dissection according to the specific type,particularly upper GC,has emerged as a prominent area of research.AIM To investigate the distribution of metastatic lymph nodes in patients with upper and lower GC and to analyze the differences in related pathological elements and prognosis.METHODS Differential analysis between upper and lower GC patients with various clinicopathological factors was performed using the chi-square test and rank-sum regression models were used to analyze risk factors affecting patient prognosis.The Kaplan-Meier method was used to construct survival curves associated with prognostic risk factors for GC.RESULTS Significant differences were observed between the two GC populations regarding tumor diameter,histological grade,pT stage,pN stage,tumor-node-metastasis(pTNM)stage,vascular invasion,and adjuvant chemotherapy usage(all P<0.05).Lymph node metastasis rates were highest for Siewert type II patients in groups Nos.1,3,2 and 7;for Siewert type III patients in groups Nos.3,1,2 and 7;and for other/unclassified patients in groups Nos.1,3,7,2.In the lower GC samples,the sequences were Nos.3,6,7,4.Pathological type,pT stage,pTNM stage,and positive vascular invasion were independent risk factors for development of lymph node metastasis.Age,pathological type,pT stage,pN stage,pTNM stage,vascular invasion,and absence of adjuvant chemotherapy were identified as independent prognostic factors.CONCLUSION Upper GC showed a significantly higher malignancy grade and different lymph node metastasis pattern than lower GC.
文摘BACKGROUND Cholecystectomy is a common surgical procedure routinely performed for patients with benign gallbladder disease.The most common indications for cholecystectomy are acute or chronic cholecystitis with or without cholelithiasis.However,in rare instances,incidental findings ranging from benign to malignant conditions are encountered,of which gallbladder adenocarcinoma is an aggre-ssive and fatal disease.AIM To determine the prevalence of all incidental diagnoses in routinely performed cholecystectomy specimens,with a particular emphasis on adenocarcinoma,and to characterize the clinicopathological characteristics of malignant postoperative specimens.METHODS The electronic medical record and institutional pathology database were searched for analyses done on gallbladder specimens from patients who had a routine cholecystectomy for benign gallbladder disease during the study period(February 2000 to February 2023).A total of 30678 cholecystectomies performed across the study period were included for analysis.Patients who had preoperative findings or radiological results concerning malignancy were excluded.The demographic and clinical data including patient age and gender,preoperative diagnosis,ra-diographic results at time of diagnosis,gross and morphologic features of gallbladder specimens,and pathologic staging parameters according to the American Joint Committee on Cancer were recorded.RESULTS Of the 30678 cholecystectomy specimens received by the Department of Pathology from patients with who had cholecystectomy for putative benign gallbladder disease during the study period,42(0.14%)were determined to be incidental gallbladder adenocarcinoma and 1 was adenocarcinoma in situ.There were 2 benign incidental dia-gnoses,including 9 patients(0.02%)with accessory/ectopic liver lobe,and 3 with paraganglioma.CONCLUSION Thorough histopathological examination of routine gallbladder specimens is important to provide an early diagnosis of unexpected gallbladder cancer to ensure that patients receive timely care when the disease is treatable.
文摘BACKGROUND Post-operative infection is a common and serious complication following drugeluting trans arterial chemo embolization(D-TACE)in patients with hepatocellular carcinoma(HCC),potentially compromising treatment efficacy and increasing morbidity.AIM To investigate the risk factors associated with post-operative infection in HCC patients undergoing D-TACE,and to provide evidence for clinical prevention and targeted intervention strategies.METHODS Clinical data of 77 primary HCC patients who underwent D-TACE in our hospital from January 2022 to December 2023 were retrospectively analyzed.Patient demographics,laboratory test results,tumor characteristics,and surgery-related parameters were collected.Univariate and multivariate logistic regression analyses were performed to identify risk factors for post-operative infection.RESULTS Post-operative infection occurred in 20 cases(25.97%)among the 77 patients.Univariate analysis showed that age≥65 years,Child-Pugh grade B,tumor diameter≥5 cm,operation time≥120 minutes,preoperative albumin<35 g/L,and comorbid diabetes were significantly associated with post-operative infection(P<0.05).Multivariate logistic regression analysis identified Child-Pugh grade B(OR=2.851,95%CI:1.426-5.698),operation time≥120 minutes(OR=2.367,95%CI:1.238-4.523),and preoperative albumin<35 g/L(OR=2.156,95%CI:1.147-4.052)as independent risk factors for post-operative infection.CONCLUSION Liver function status,operation time,and preoperative albumin level are significant factors affecting post-operative infection in HCC patients undergoing D-TACE.For high-risk patients,enhanced perioperative management,appropriate timing of surgery,and active improvement of nutritional status should be implemented to reduce the risk of post-operative infection.

文摘Traumatic spinal cord injury is potentially catastrophic and can lead to permanent disability or even death.China has the largest population of patients with traumatic spinal cord injury.Previous studies of traumatic spinal cord injury in China have mostly been regional in scope;national-level studies have been rare.To the best of our knowledge,no national-level study of treatment status and economic burden has been performed.This retrospective study aimed to examine the epidemiological and clinical features,treatment status,and economic burden of traumatic spinal cord injury in China at the national level.We included 13,465 traumatic spinal cord injury patients who were injured between January 2013 and December 2018 and treated in 30 hospitals in 11 provinces/municipalities representing all geographical divisions of China.Patient epidemiological and clinical features,treatment status,and total and daily costs were recorded.Trends in the percentage of traumatic spinal cord injuries among all hospitalized patients and among patients hospitalized in the orthopedic department and cost of care were assessed by annual percentage change using the Joinpoint Regression Program.The percentage of traumatic spinal cord injuries among all hospitalized patients and among patients hospitalized in the orthopedic department did not significantly change overall(annual percentage change,-0.5%and 2.1%,respectively).A total of 10,053(74.7%)patients underwent surgery.Only 2.8%of patients who underwent surgery did so within 24 hours of injury.A total of 2005(14.9%)patients were treated with high-dose(≥500 mg)methylprednisolone sodium succinate/methylprednisolone(MPSS/MP);615(4.6%)received it within 8 hours.The total cost for acute traumatic spinal cord injury decreased over the study period(-4.7%),while daily cost did not significantly change(1.0%increase).Our findings indicate that public health initiatives should aim at improving hospitals’ability to complete early surgery within 24 hours,which is associated with improved sensorimotor recovery,increasing the awareness rate of clinical guidelines related to high-dose MPSS/MP to reduce the use of the treatment with insufficient evidence.
文摘BACKGROUND Early gastric cancer(EGC)is a common malignant tumor of the digestive system,and its lymph node metastasis and survival prognosis have been concerning.By retrospectively analyzing the clinical data of EGC patients,we can better under-stand the status of lymph node metastasis and its impact on survival and prog-nosis.AIM To evaluate the prognosis of EGC patients and the factors that affect lymph node METHODS The clinicopathological data of 1011 patients with EGC admitted to our hospital between January 2015 and December 2023 were collected in a retrospective cohort study.There were 561 males and 450 females.The mean age was 58±11 years.The patient underwent radical gastrectomy.The status of lymph node metastasis in each group was determined according to the pathological examination results of surgical specimens.The outcomes were as follows:(1)Lymph node metastasis in EGC patients;(2)Analysis of influencing factors of lymph node metastasis in EGC;and(3)Analysis of prognostic factors in patients with EGC.Normally distributed measurement data are expressed as mean±SD,and a t test was used for comparisons between groups.The data are expressed as absolute numbers or percentages,and the chi-square test was used for comparisons between groups.Rank data were compared using a nonparametric rank sum test.A log-rank test and a logistic regression model were used for univariate analysis.A logistic stepwise regression model and a Cox stepwise regression model were used for multivariate analysis.The Kaplan-Meier method was used to calculate the survival rate and construct survival curves.A log-rank test was used for survival analysis.RESULTS Analysis of influencing factors of lymph node metastasis in EGC.The results of the multifactor analysis showed that tumor length and diameter,tumor site,tumor invasion depth,vascular thrombus,and tumor differentiation degree were independent influencing factors for lymph node metastasis in patients with EGC(odds ratios=1.80,1.49,2.65,5.76,and 0.60;95%CI:1.29–2.50,1.11–2.00,1.81–3.88,3.87-8.59,and 0.48-0.76,respectively;P<0.05).Analysis of prognostic factors in patients with EGC.All 1011 patients with EGC were followed up for 43(0–13)months.The 3-year overall survival rate was 97.32%.Multivariate analysis revealed that age>60 years and lymph node metastasis were independent risk factors for prognosis in patients with EGC(hazard ratio=9.50,2.20;95%CI:3.31-27.29,1.00-4.87;P<0.05).Further analysis revealed that the 3-year overall survival rates of gastric cancer patients aged>60 years and≤60 years were 99.37%and 94.66%,respectively,and the difference was statistically significant(P<0.05).The 3-year overall survival rates of patients with and without lymph node metastasis were 95.42%and 97.92%,respectively,and the difference was statistically significant(P<0.05).CONCLUSION The lymph node metastasis rate of EGC patients was 23.64%.Tumor length,tumor site,tumor infiltration depth,vascular cancer thrombin,and tumor differentiation degree were found to be independent factors affecting lymph node metastasis in EGC patients.Age>60 years and lymph node metastasis are independent risk factors for EGC prognosis.

文摘BACKGROUND Hepatocellular carcinoma(HCC)is the third leading cause of cancer death worldwide,with a 5-year relative survival rate of approximately 18%.The similarity between incidence and mortality(830000 deaths per year)underscores the bleak prognosis associated with the disease.HCC is the fourth most common malignancy and the second leading cause of cancer death in China.Most patients with HCC have a history of chronic liver disease such as chronic hepatitis B virus(HBV)or hepatitis C virus(HCV)infection,alcoholism or alcoholic steatohepatitis,nonalcoholic fatty liver disease,or nonalcoholic steatohepatitis.Early diagnosis and effective treatment are the keys to improving the prognosis of patients with HCC.Although the total number of human immunodeficiency virus(HIV)-infected patients is declining globally the incidence of HCC is increasing in HIVinfected patients,especially those who are coinfected with HBV or HCV.As a result,people infected with HIV still face unique challenges in terms of their risk of developing HCC.AIM To investigate the survival prognosis and clinical efficacy of surgical resection in patients with HCC complicated with HIV infection.METHODS The clinical data of 56 patients with HCC complicated with HIV admitted to the Third Affiliated Hospital of Nantong University from January 2013 to December 2023 were retrospectively analyzed.Among these,27 patients underwent hepatectomy(operation group)and 29 patients received conservative treatment(nonoperation group).All patients signed informed consents in line with the provisions of medical ethics.The general data,clinicopathological features and prognoses for the patients in the two groups were analyzed and the risk factors related to the prognoses of the patients in the operation group were identified.RESULTS The median disease-free survival(DFS)and overall survival(OS)of HIV-HCC patients in the surgical group were 13 months and 17 months,respectively,and the median OS of patients in the nonsurgical group was 12 months.The OS of the surgical group was significantly longer than that of the control group(17 months vs 12 months,respectively;P<0.05).The risk factors associated with DFS and OS in the surgical group were initial HIV diagnosis,postoperative microvascular invasion(MVI),a CD4+T-cell count<200/μL,Barcelona stage C-D,and men who have sex with men(MSM;P<0.05).CONCLUSION Hepatectomy can effectively prolong the survival of patients with HIV-HCC but MVI identified during postoperative pathological examination,late tumor detection,late BCLC stage,CD4+T<200/μL and MSM are risk factors affecting the survival and prognosis of patients undergoing hepatectomy.In addition,there were significant differences between the surgical group and the nonsurgical group in terms of the initial diagnosis of HIV,Child-Pugh score,alpha-fetoprotein measurement value,and HART-efficient antiretroviral therapy after the diagnosis of HIV(P<0.05).Therefore,these factors may also affect the survival and prognosis of patients.

文摘BACKGROUND In recent years,approximately half of the newly diagnosed cases and mortalities attributed to hepatocellular carcinoma(HCC)have been reported in China.Despite the high incidence of HCC,there remains a paucity of data regarding the natural growth pattern and the determination of optimal surveillance intervals specific to the Chinese population.AIM To quantify the natural tumor growth pattern of HCC in regional China.METHODS A retrospective analysis was performed on patients from a single institution in Southwest China who had undergone two or more serial dynamic computed tomography or magnetic resonance imaging scans between 2014 and 2020,without having received any anti-cancer therapy.Tumor growth was assessed using tumor volume doubling time(TVDT)and tumor growth rate(TGR),with volumes measured manually by experienced radiologists.Simple univariate linear regression and descriptive analysis were applied to explore associations between growth rates and clinical factors.RESULTS This study identifies the median TVDT for HCC as 163.4 d,interquartile range(IQR)72.1 to 302.3 d,with a daily TGR of 0.42%(IQR 0.206%-0.97%).HCC growth patterns reveal that about one-third of tumors grow indolently with TVDT exceeding 270 d,another one-third of tumors exhibit rapid growth with TVDT under 90 d,and the remaining tumors show intermediate growth rates,with TVDT ranging between 3 to 9 months.CONCLUSION The identified TGRs support biannual surveillance and follow-up for HCC patients in certain regions of China.Given the observed heterogeneity in HCC growth,further investigation is warranted.

文摘Objective:Accurate measurement of QT interval,the ventricular action potential from depolarization to repolarization,is important for the early detection of Long QT syndrome.The most effective QT correction(QTc)formula has yet to be determined in the pediatric population,although it has intrinsically greater extremes in heart rate(HR)and is more susceptible to errors in measurement.The authors of this study compare six dif-ferent QTc methods(Bazett,Fridericia,Framingham,Hodges,Rautaharju,and a computer algorithm utilizing the Bazett formula)for consistency against variations in HR and RR interval.Methods:Descriptive Retrospective Study.We included participants from a pediatric cardiology practice of a community hospital who had an ECG performed in 2017.All participants were healthy patients with no past medical history and no regular med-ications.Results:ECGs from 95 participants from one month to 21 years of age(mean 9.7 years)were included with a mean HR of 91 beats per minute(bpm).The two-sample paired t-test or Wilcoxon signed-rank test assessed for any difference between QTc methods.A statistically significant difference was observed between every combination of two QTc formulae.The Spearman’s rank correlation analysis explored the QTc/HR and QTc/RR relationships for each formula.Fridericia method was most independent of HR and RR with the lowest absolute value of correlation coefficients.Bazett and Computer had moderate correlations,while Framingham and Rautaharju exhibited strong correlations.Correlations were positive for Bazett and Computer,reflecting results from prior studies demonstrating an over-correction of Bazett at higher HRs.In the linear QTc/HR regression analysis,Bazett had the slope closest to zero,although Computer,Hodges,and Fridericia had comparable values.Alternatively,Fridericia had the linear QTc/RR regression coefficient closest to zero.The Bland-Altman method assessed for bias and the limits of agreement between correction formulae.Bazett and Computer exhibited good agreement with minimal bias along with Framingham and Rautaharju.To account for a possible skewed distri-bution of QT,all the above analyses were also performed excluding the top and bottom 2%of data as sorted by heart rate ranges(N=90).Results from this data set were consistent with those derived from all participants(N=95).Conclusions:Overall,the Fridericia correction method provided the best rate correction in our pedia-tric study cohort.
