Methods: Forty patients with advanced gastric and ovarian cancer with ascites, treated in our hospital from January 2021 to August 2024, were selected as research subjects. They were divided into a treatment group and a reference group using a random number table method. The treatment group received hypotonic hyperthermic intraperitoneal chemotherapy, while the reference group received conventional treatment. The treatment effects of the two groups were compared. Results: In the treatment group, the ascite disappearance time was (6.13 ± 1.32) days, and the recurrence time was (22.58 ± 8.21) months. The ascite disappearance time was significantly shorter than that of the reference group, and the ascite recurrence time was significantly longer. Both P-values were less than 0.05, indicating statistical significance. The effective rate of quality of life improvement was 95%, with only 1 patient showing a decrease in quality of life. The effective rate of ascites treatment was 95%, with only 1 patient showing an increase in ascites. Both the quality of life improvement rate and the effective rate of ascites treatment were significantly higher than those of the reference group, with P-values of 0.037 and 0.018, respectively, indicating statistical significance. Conclusion: For patients with advanced gastric and ovarian cancer with ascites, hypotonic hyperthermic intraperitoneal chemotherapy can accelerate ascites disappearance, prolong the time to recurrence, and significantly improve both the quality of life improvement rate and the effective rate of ascites treatment.展开更多

A new strategy combining maximal cytoreductive surgery(CRS) with intraoperative hyperthermic intraperitoneal chemotherapy(HIPEC) has been proposed to treat advanced stage EOC in the primary setting. Numerous small, heterogeneous studies have been conducted exploring outcomes in patients with predominantly advanced, recurrent or refractory disease treated with CRS + HIPEC. Although morbidity rates approaching 35% have been reported, oncologic outcomes are promising. Incorporation of HIPEC for the treatment of primary EOC has continued to gain interest. Several prospective phase 2 clinical trials were recently completed evaluating the impact of CRS + HIPEC in the primary setting. This article will briefl y discuss the benefi ts of optimal surgical cytoreduction and the theoretical basis of intraperitoneal chemotherapy in patients with advanced stage EOC, and will then review existing literature describing oncologic outcomes in EOC patients treated with HIPEC in the primary setting.展开更多

All experimental animals were divided into four groups. On the sixth day post implantation, in group A (controlgroup) 6 ml of saline was injected intraperitoneally once a day for 3 days. In group B (single chemotherapy group) 6 ml of 5-Fu 75 mg/kg was injected intraperitoneally once a day for 3 days. In group C (combination of treatment group) both 5-Fu (75 mg/kg) and verapamil(25 mg/kg) were administered simultaneously as in A and B. In group D (simple verapamil group) only 6 ml of verapamil (25 mg/kg)was administered as above.Results Compared with groups A, B and D, The volume of cancer and the contents of liver cancer DNA and protein were significantlyreduced. The rates of inhibiting cancer (89.9% in group C and 35.4% in group B) were significantly increased in group C. Group C hadsignificantly long survival time compared to groups A, B and D ( P < 0.05) . By light microscopy, a number of focal necroses were foundin cancer tissue in group C.Conclusion Calcium channel blockers can enhance the antineoplastic effect of 5-Fu intraperitoneal chemotherapy to liver cancer ; Theuse of verapamil can not increase the toxicity of 5-Fu.展开更多

METHODS： Fifty-three patients affected by PMP underwent cytoreduction （CCR） and HIPEC with a ＂semi-closed＂ abdomen technique in our institution. The peritonectomy procedure and completeness of CCR were classified according to Sugarbaker criteria. Preoperative evaluation always included thoracic and abdominal CT scan to stage peritoneal disease and exclude distant metastases. Fifty-one patients in our series were treated with a protocol based on administration of cisplatinum 100 mg/m^2 plus mitomycin C 16 mg/m^2, at a temperature of 41.5℃ for 60 min. Anastomoses were always performed at the end of HIPEC. The mean duration of surgery was 12 h including HIPEC. Continuous monitoring of hepatic and renal functions and hydroelectrolytic balance was performed in the postoperative period. RESULTS： Twenty-four patients presented with postoperative complications： surgical morbidity was observed in 16 patients and 6 patients were reoperated. All complications were successfully treated and no postoperative deaths were observed. Risk factors for postoperative morbidity were considered to be gender, age, body surface, duration of surgery,Peritoneal Cancer Index （PCI） and tumor residual value （CC score）. No statistically significant correlation was found during the multivariate analysis： only the CC score was statistically significant. The OS in our experience was 81.8%, with a DFS of 80% at 5 years and of 70% at 10 years. CONCLUSION： In our experience, even if HIPEC combined with cytoreductive surgery involves a high risk of morbidity, postoperative complications can be resolved favorably in most cases with correct patient selection and adequate postoperative care, thus minimizing mortality. The association of CCR and HIPEC can be considered as the standard treatment for PNP. The OS and DFS results confirm the validity of this combined approach for the treatment of this rare neoplasm. The impact of preoperative chemotherapy on OS, in our opinion, is due to a major aggressiveness of tumors in treated patients.展开更多

In addition to reviewing the natural history of gastric cancer with peritoneal carcinomatosis, this mini-review examines literature on the efficacy of CRS and HIPEC as compared to chemotherapy and surgical options. Both randomized and nonrandomized studies were summarized with the emphasis focused on overall survival. In summary, CRS and HIPEC are indeed a promising treatment option for gastric cancer with peritoneal carcinomatosis and large randomized clinical trials are warranted.展开更多

We describe a case of...There are diverse protocols to manage patients with recurrent disease after primary cytoreductive surgery(CRS) with hyperthermic intraperitoneal chemotherapy(HIPEC) for peritoneal carcinomatosis. We describe a case of metachronous liver metastasis after CRS and HIPEC for colorectal cancer, successfully treated with a selective metastectomy and partial graft of the inferior vena cava. A 35-year-old female presented with a large tumour in the cecum and consequent colonic stenosis. After an emergency right colectomy, the patient received adjuvant chemotherapy. One year later she was diagnosed with peritoneal carcinomatosis, and it was decided to carry out a CRS/HIPEC. After 2 years of total remission, an isolated metachronous liver metastasis was detected by magnetic resonance imaging surveillance. The patient underwent a third procedure including a caudate lobe and partial inferior vena cava resection with a prosthetic graft interposition, achieving an R0 situation. The postoperative course was uneventful and the patient was discharged on postoperative day 17 after the liver resection. At 18-mo follow-up after the liver resection the patient remained free of recurrence. In selected patients, the option of re-operation due to recurrent disease should be discussed. Even liver resection of a metachronous metastasis and an extended vascular resection are acceptable after CRS/HIPEC and can be considered as a potential treatment option to remove all macroscopic lesions.展开更多

文摘Cytoreductive surgery(CRS)and hyperthermic intraperitoneal chemotherapy(HIPEC)are complex surgical procedures that are often used to treat advanced cancers of the abdominal cavity with peritoneal metastasis.Although these treatments can be lifesaving,patients often experience a significant decrease in their overall quality of life(QoL),especially in the early stages of recovery,owing to the physical burden of surgery and the effects of chemotherapy.Many traditional QoL questionnaires have been used to measure CRS and HIPEC.However,these classical current QoL assessment tools often fail to capture the unique challenges faced by this population,including bowel dysfunction,stoma-related distress,and long-term survivorship issues.Therefore,additional parameters that assess bowel function and stoma opening status and especially patient-reported outcome measures would be useful in QoL measurements to provide a more detailed understanding of recovery and general well-being in these patients.
文摘Gastric cancer with peritoneal carcinomatosis(PC)remains a formidable challenge in oncological care,especially regarding surgical intervention.Integrating enhanced recovery after surgery(ERAS)protocols into gastrectomy with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy has emerged as a promising approach.This minireview explores the influence of ERAS on surgical and oncological outcomes in this multifaceted procedure.Recent evidence suggests that ERAS,comprising multimodal strategies,improves postoperative recovery,reduces complications,and enhances quality of life.It may also contribute to better survival outcomes by minimizing perioperative morbidity and thereby facilitating the timely initiation of adjuvant therapy.Mechanistically,ERAS promotes early mobilization,attenuates postoperative immunosuppression,and supports timely adjuvant therapies,which are crucial in managing carcinomatosis.This minireview underscores the importance of multidisciplinary collaboration and individualized patient care to maximize ERAS benefits.Large-scale,prospective investigations are warranted to validate these findings and refine ERAS protocols for this specialized patient cohort.Further research will facilitate ongoing advancements in oncological surgery and perioperative care,ultimately improving outcomes for patients with gastric cancer and PC.

文摘Objective:The trial was designed to evaluate the efficacy of prophylactic hyperthermic intraperitoneal chemotherapy(HIPEC)with cisplatin for patients with locally advanced gastric cancer(LAGC).Methods:Between March 2015 and November 2016,a phase Ⅱ clinical trial was performed.Fifty consecutive patients with LAGC were randomly assigned to two groups:the experimental group(radical gastrectomy+HIPEC with cisplatin+adjuvant chemotherapy)and the control group(radical gastrectomy+adjuvant chemotherapy).Survival rates were closely monitored.Results:The 5-year overall survival(OS)rate of all patients was 80.0%.The 5-year OS rate in the experimental group was lower than that in the control group,at 75.8%and 88.2%,respectively,with no statistical significance.In addition,5-year recurrence-free survival(RFS)rates of patients who underwent HIPEC or not were also 75.8%and 88.2%,respectively.In the multivariate analysis,only pT stage[risk ratio(RR)=7.079,P=0.018]was significantly associated with prognosis.The most common recurrence pattern was peritoneal recurrence in both groups.The experimental group had a lower incidence of peritoneal recurrence than the control group with no statistical significance.Conclusions:This trial clearly revealed that prophylactic HIPEC with cisplatin neither decrease the risk of peritoneal recurrence nor improve the prognosis of patients with LAGC.Thus,HIPEC with cisplatin is not recommended as a prophylactic treatment for peritoneal recurrence of LAGC after radical gastrectomy.
文摘BACKGROUND Gastric cancer presenting with peritoneal metastasis is notably associated with diminished survival prospects.The use of cytoreductive surgery in conjunction with hyperthermic intraperitoneal chemotherapy(HIPEC)has been shown to increase survival rates in these patients.Despite these advancements,debates persist regarding the magnitude of survival improvement attributed to this treatment modality.The present investigation examined survival outcomes following HIPEC in individuals diagnosed with gastric cancer and peritoneal metastasis,and it took a comparative analysis of patients exhibiting positive and negative cytological findings.Between April 2013 and March 2020,84 patients with advanced gastric cancer treated at our institution were categorized into three cohorts:HIPEC(20 patients with peritoneal metastasis),cytology-positive(23 patients without peritoneal nodules but with positive wash cytology),and cytology-negative(41 patients with advanced gastric cancer,no peritoneal nodules,and negative wash cytology).The HIPEC cohort underwent gastrectomy with HIPEC,while the cytology-positive and cytology-negative groups received gastrectomy alone.The demographic,pat-hological,and survival data of the groups were compared.RESULTS The HIPEC cohort-predominantly younger females-exhibited relatively extended surgical durations and high blood loss.Nevertheless,the complication rates were consistent across all three groups.Median survival in the HIPEC group was 20.00±4.89 months,with 1-year,2-year,and 3-year overall survival rates of 73.90%,28.70%,and 9.60%,respectively.These figures paralleled the survival rates of the cytology-positive group(52.20%at 1 year,28.50%at 2 years,and 19.00%at 3 years).Notably,47%of patients experienced peritoneal recurrence.CONCLUSION HIPEC may offer a modest improvement in short-term survival for patients with gastric cancer and peritoneal metastasis,mirroring the outcomes in cytology-positive patients.However,peritoneal recurrence remained high.

文摘BACKGROUND Although cytoreductive surgery(CRS)and hyperthermic intraperitoneal chemotherapy(HIPEC)offer the potential for long-term survival in peritoneal carcinomatosis,outcomes following CRS/HIPEC vary significantly.AIM To identify the clinical factors associated with progression-free survival(PFS)after complete CRS/HIPEC in patients with colorectal/high-grade appendiceal,ovarian,and gastric cancers.METHODS We retrospectively evaluated the risk of recurrence within 1 year after CRS/HIPEC and its impact on overall survival(OS)in patients recruited between 2015 and 2020.Logistic regression models were used to assess the prognostic factors for the risk of recurrence within 1 year.Kaplan–Meier survival curves and Cox proportional hazards models were used to evaluate the association between recurrence and OS.RESULTS Of the 80 enrolled patients,39 had an unfavorable PFS(<1 year)and 41 had a favorable PFS(≥1 year).Simple logistic models revealed that the patients with a completeness of cytoreduction score of 0(CC-0)or length of CRS≤6 h had a favorable PFS[odds ratio(OR)=0.141,P=0.004;and OR=0.361,P=0.027,respectively].In multiple logistic regression,achieving CC-0 was the strongest prognostic factor for a favorable PFS(OR=0.131,P=0.005).A peritoneal cancer index score>12 was associated with a lower rate of achieving CC-0(P=0.027).The favorable PFS group had a significantly longer OS(median 81.7 mo vs 17.0 mo,P<0.001).CONCLUSION Achieving CC-0 was associated with a lower early recurrence rate and improved long-term survival.This study underscores the importance of selecting appropriate candidates for CRS/HIPEC to manage peritoneal carcinomatosis.
文摘Objective: To observe the time of ascites disappearance, time to ascites recurrence, improvement rate in quality of life, and the effective rate of ascites treatment in patients with advanced gastric and ovarian cancer with ascites following hypotonic hyperthermic intraperitoneal chemotherapy. Methods: Forty patients with advanced gastric and ovarian cancer with ascites, treated in our hospital from January 2021 to August 2024, were selected as research subjects. They were divided into a treatment group and a reference group using a random number table method. The treatment group received hypotonic hyperthermic intraperitoneal chemotherapy, while the reference group received conventional treatment. The treatment effects of the two groups were compared. Results: In the treatment group, the ascite disappearance time was (6.13 ± 1.32) days, and the recurrence time was (22.58 ± 8.21) months. The ascite disappearance time was significantly shorter than that of the reference group, and the ascite recurrence time was significantly longer. Both P-values were less than 0.05, indicating statistical significance. The effective rate of quality of life improvement was 95%, with only 1 patient showing a decrease in quality of life. The effective rate of ascites treatment was 95%, with only 1 patient showing an increase in ascites. Both the quality of life improvement rate and the effective rate of ascites treatment were significantly higher than those of the reference group, with P-values of 0.037 and 0.018, respectively, indicating statistical significance. Conclusion: For patients with advanced gastric and ovarian cancer with ascites, hypotonic hyperthermic intraperitoneal chemotherapy can accelerate ascites disappearance, prolong the time to recurrence, and significantly improve both the quality of life improvement rate and the effective rate of ascites treatment.

文摘Advanced stage epithelial ovarian cancer(EOC) is diffi cult to treat with low overall cure rates. A new strategy combining maximal cytoreductive surgery(CRS) with intraoperative hyperthermic intraperitoneal chemotherapy(HIPEC) has been proposed to treat advanced stage EOC in the primary setting. Numerous small, heterogeneous studies have been conducted exploring outcomes in patients with predominantly advanced, recurrent or refractory disease treated with CRS + HIPEC. Although morbidity rates approaching 35% have been reported, oncologic outcomes are promising. Incorporation of HIPEC for the treatment of primary EOC has continued to gain interest. Several prospective phase 2 clinical trials were recently completed evaluating the impact of CRS + HIPEC in the primary setting. This article will briefl y discuss the benefi ts of optimal surgical cytoreduction and the theoretical basis of intraperitoneal chemotherapy in patients with advanced stage EOC, and will then review existing literature describing oncologic outcomes in EOC patients treated with HIPEC in the primary setting.
文摘Objective To study the antineoplastic effect of the calcium channel blocker verapamil and 5-fluorouracil intraperitoneal chemotherapy onhepatocarcinoma-bearing rats, and examine the action between calcium channel blockers and cytotoxic drugs.Methods We adopted the method of subcapsular implantation of carcinoma tissues of walker-256 in the left liver lobe as a model of livercarcinoma-bearing rats. All experimental animals were divided into four groups. On the sixth day post implantation, in group A (controlgroup) 6 ml of saline was injected intraperitoneally once a day for 3 days. In group B (single chemotherapy group) 6 ml of 5-Fu 75 mg/kg was injected intraperitoneally once a day for 3 days. In group C (combination of treatment group) both 5-Fu (75 mg/kg) and verapamil(25 mg/kg) were administered simultaneously as in A and B. In group D (simple verapamil group) only 6 ml of verapamil (25 mg/kg)was administered as above.Results Compared with groups A, B and D, The volume of cancer and the contents of liver cancer DNA and protein were significantlyreduced. The rates of inhibiting cancer (89.9% in group C and 35.4% in group B) were significantly increased in group C. Group C hadsignificantly long survival time compared to groups A, B and D ( P < 0.05) . By light microscopy, a number of focal necroses were foundin cancer tissue in group C.Conclusion Calcium channel blockers can enhance the antineoplastic effect of 5-Fu intraperitoneal chemotherapy to liver cancer ; Theuse of verapamil can not increase the toxicity of 5-Fu.
文摘AIM： To investigate the most important aspects of hyperthermic intraperitoneal chemotherapy （HIPEC） that has been accepted as the standard treatment for pseudomyxoma peritonei （PMP）, with special regard to morbidity, overall survival （OS） and disease free survival （DFS） over 10 years. METHODS： Fifty-three patients affected by PMP underwent cytoreduction （CCR） and HIPEC with a ＂semi-closed＂ abdomen technique in our institution. The peritonectomy procedure and completeness of CCR were classified according to Sugarbaker criteria. Preoperative evaluation always included thoracic and abdominal CT scan to stage peritoneal disease and exclude distant metastases. Fifty-one patients in our series were treated with a protocol based on administration of cisplatinum 100 mg/m^2 plus mitomycin C 16 mg/m^2, at a temperature of 41.5℃ for 60 min. Anastomoses were always performed at the end of HIPEC. The mean duration of surgery was 12 h including HIPEC. Continuous monitoring of hepatic and renal functions and hydroelectrolytic balance was performed in the postoperative period. RESULTS： Twenty-four patients presented with postoperative complications： surgical morbidity was observed in 16 patients and 6 patients were reoperated. All complications were successfully treated and no postoperative deaths were observed. Risk factors for postoperative morbidity were considered to be gender, age, body surface, duration of surgery,Peritoneal Cancer Index （PCI） and tumor residual value （CC score）. No statistically significant correlation was found during the multivariate analysis： only the CC score was statistically significant. The OS in our experience was 81.8%, with a DFS of 80% at 5 years and of 70% at 10 years. CONCLUSION： In our experience, even if HIPEC combined with cytoreductive surgery involves a high risk of morbidity, postoperative complications can be resolved favorably in most cases with correct patient selection and adequate postoperative care, thus minimizing mortality. The association of CCR and HIPEC can be considered as the standard treatment for PNP. The OS and DFS results confirm the validity of this combined approach for the treatment of this rare neoplasm. The impact of preoperative chemotherapy on OS, in our opinion, is due to a major aggressiveness of tumors in treated patients.

文摘Objective:Systemic chemotherapy has limited efficacy in the treatment of peritoneal metastasis(PM)in gastric cancer(GC).Hyperthermic intraperitoneal chemotherapy(HIPEC)combined with complete cytoreductive surgery(CRS)has shown promising outcomes but remains controversial.The present study aimed to evaluate the safety and efficacy of HIPEC without CRS in GC patients with PM.Methods:This retrospective propensity score-matched multicenter cohort study included GC patients with PM treated with either chemotherapy alone(Cx group)or with HIPEC combined with chemotherapy(HIPEC-Cx group)in four Chinese high-volume gastric medical centers between 2010 and 2017.The primary outcomes were median survival time(MST)and 3-year overall survival(OS).Propensity score matching was performed to compensate for controlling potential confounding effects and selection bias.Results:Of 663 eligible patients,498 were matched.The MST in the Cx and HIPEC-Cx groups was 10.8 and 15.9 months,respectively[hazard ratio(HR)=0.71,95%confidence interval(95%CI),0.58-0.88;P=0.002].The 3-year OS rate was 10.1%(95%CI,5.4%-14.8%)and 18.4%(95%CI,12.3%-24.5%)in the Cx and HIPEC-Cx groups,respectively(P=0.017).The complication rates were comparable.The time to first flatus and length of hospital stay for patients undergoing HIPEC combined with chemotherapy was longer than that of chemotherapy alone(4.6±2.4 d vs.2.7±1.8 d,P<0.001;14.2±5.8 d vs.11.4±7.7 d,P<0.001),respectively.The median follow-up period was 33.2 months.Conclusions:Compared with standard systemic chemotherapy,HIPEC combined with chemotherapy revealed a statistically significant survival benefit for GC patients with PM,without compromising patient safety.
文摘Advanced gastric cancer （GC） has been recognized as lethal disease when peritoneal metastases （PM） occurred.There is no standard treatment for advanced GC with PM.Until 1980s,the therapeutic arena for these patients had remained stagnant,with no therapeutic approach having shown a survival gain in GC with PM.However,cytoreductive surgery （CRS） with peritonectomy procedures and intraperitoneal chemotherapy （IPC） promising new combined therapeutic approach to achieve disease control for GC with PM.The recent publications changed the GC with PM treatment landscape by providing an evidence that CRS and IPC led to prolongation in overall survival （OS）.This review will provide an overview of the evolving role of CRS and IPC in the management of advanced GC with PM in the current era.
文摘Peritoneal carcinomatosis in gastric cancer is associated with a dismal prognosis.Systemic chemotherapy is not effective because of the existence of a blood-peritoneal barrier.Cytoreductive surgery and intraperitoneal chemotherapy can improve survival and quality of life in selected patients.Patient selection for this multimodal approach is one of the most critical issues,and calls for interdisciplinary evaluation by radiologists,medical and surgical oncologists,and anaesthetists.This article sets forth criteria for selection of gastric cancer patients suffering from peritoneal carcinomatosis.

文摘Objective:Intraperitoneal(IP)chemotherapy through subcutaneous port is an effective treatment for gastric cancer(GC)patients with peritoneal metastasis(PM).The objective of this study is to assess the port complications and risk factors for complications in GC patients with PM.Methods:In retrospective screening of 301 patients with subcutaneous ports implantation,249 GC patients with PM who received IP chemotherapy were screened out for analysis.Port complications and risk factors for complications were analyzed.Results:Of the 249 analyzed patients,57(22.9%)experienced port complications.Subcutaneous liquid accumulation(42.1%)and infection(28.1%)were the main complications,and other complications included port rotation(14.1%),wound dehiscence(12.3%),inflow obstruction(1.7%)and subcutaneous metastasis(1.7%).The median interval between port implantation and occurrence of complications was 3.0 months.Eastern Cooperative Oncology Group(ECOG)performance status[odds ratio(OR),1.74;95%confidence interval(95%CI),1.12-2.69],albumin(OR,3.67;95%CI,1.96-6.86),implantation procedure optimization(OR,0.33;95%CI,0.18-0.61)and implantation groups(OR,0.37;95%CI,0.20-0.69)were independent risk factors for port complications(P<0.05).ECOG performance status was the only factor that related to the grades of port complications(P=0.016).Conclusions:Port complications in GC patients who received IP chemotherapy are manageable.ECOG performance status,albumin,implantation procedure and implantation group are independent risk factors for port complications in GC patients with PM.
文摘BACKGROUND Gastric cancer is the second most common malignant tumor in China,ranking third among all malignant tumor mortality rates.Hyperthermic intraperitoneal chemotherapy(HIPEC)has been shown to increase significantly the effectiveness of intraperitoneal chemotherapeutic drugs,prolong the action time of these drugs on intraperitoneal tumor cells,and enhance their diffusion in tumor tissues.HIPEC may be one of the best choices for the eradication of residual cancer cells in the abdominal cavity.AIM The aim of this study was to study the role of preventive HIPEC after radical gastrectomy.METHODS A prospective analysis was performed with patients with c T4 N0-3 M0 gastric cancer to compare the effects of postoperative prophylactic HIPEC plus intravenous chemotherapy with those of routine adjuvant chemotherapy.Patients’medical records were analyzed,and differences in the peritoneal recurrence rate,diseasefree survival time,and total survival time between groups were examined.RESULTS The first site of tumor recurrence was the peritoneum in 11 cases in the conventional adjuvant chemotherapy group and in 2 cases in the HIPEC group(P=0.020).The 1-year and 3-year disease-free survival rates were 91.9%and 60.4%,respectively,in the conventional adjuvant chemotherapy group and 92.1%and 63.0%,respectively,in the HIPEC group.The 1-year and 3-year overall survival rates were 95.2%and 66.3%,respectively,in the conventional adjuvant chemotherapy group and 96.1%and 68.6%,respectively,in the HIPEC group.No significant difference in postoperative or chemotherapy complications was observed between groups.CONCLUSION In patients with c T4 N0-3 M0 gastric cancer,prophylactic HIPEC after radical tumor surgery is beneficial to reduce peritoneal tumor recurrence and prolong survival.
文摘Although gastric cancer with peritoneal carcinomatosis is associated with poor prognosis and is generally treated with palliative systemic therapy, recent studies have shown that cytoreductive surgery（CRS） and hyperthermic intraperitoneal chemotherapy（HIPEC） may prove to be an efficacious treatment option. In addition to reviewing the natural history of gastric cancer with peritoneal carcinomatosis, this mini-review examines literature on the efficacy of CRS and HIPEC as compared to chemotherapy and surgical options. Both randomized and nonrandomized studies were summarized with the emphasis focused on overall survival. In summary, CRS and HIPEC are indeed a promising treatment option for gastric cancer with peritoneal carcinomatosis and large randomized clinical trials are warranted.
文摘There are diverse protocols to manage patients with recurrent disease after primary cytoreductive surgery(CRS) with hyperthermic intraperitoneal chemotherapy(HIPEC) for peritoneal carcinomatosis. We describe a case of metachronous liver metastasis after CRS and HIPEC for colorectal cancer, successfully treated with a selective metastectomy and partial graft of the inferior vena cava. A 35-year-old female presented with a large tumour in the cecum and consequent colonic stenosis. After an emergency right colectomy, the patient received adjuvant chemotherapy. One year later she was diagnosed with peritoneal carcinomatosis, and it was decided to carry out a CRS/HIPEC. After 2 years of total remission, an isolated metachronous liver metastasis was detected by magnetic resonance imaging surveillance. The patient underwent a third procedure including a caudate lobe and partial inferior vena cava resection with a prosthetic graft interposition, achieving an R0 situation. The postoperative course was uneventful and the patient was discharged on postoperative day 17 after the liver resection. At 18-mo follow-up after the liver resection the patient remained free of recurrence. In selected patients, the option of re-operation due to recurrent disease should be discussed. Even liver resection of a metachronous metastasis and an extended vascular resection are acceptable after CRS/HIPEC and can be considered as a potential treatment option to remove all macroscopic lesions.
文摘BACKGROUND Almost all elderly patients with peritoneal metastatic gastric cancer(PGC)are unlikely to tolerate cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy(HIPEC)and adjuvant chemotherapy.However,determining how to optimize the treatment strategy for such patients has always been a clinical problem.Both HIPEC and palliative adjuvant chemotherapy can benefit patients with PGC.Therefore,optimizing HIPEC and chemotherapy regimens has potential clinical value in reducing side effects,and improving treatment tolerance and clinical effectiveness.AIM To explore the effect of HIPEC containing elemene,which is an anti-cancer component extracted in traditional Chinese herbal medicine,combined with reduced capecitabine and oxaliplatin(CapeOx)chemotherapy regimens,in elderly patients with PGC.METHODS In the present study,39 of 52 elderly PGC patients were included and assigned to different HIPEC treatment groups[lobaplatin group(group L)and mixed group(group M)]for analysis.Lobaplatin was used for all three HIPECs in group L.In group M,lobaplatin was used in the middle of the three HIPECs,and elemene was used for the first and third HIPEC.After HIPEC,patients received CapeOx chemotherapy.The incidence of complications(abdominal infection,lung infection,and urinary tract infection),myelosuppression,immune function(CD4/CD8 ratio),average length of hospital stay,and prognosis were compared between these two groups.RESULTS There was no significant difference in the incidence of complications between the two groups during hospitalization(P>0.05).Compared to patients in group M,patients in group L exhibited severe myelosuppression(P=0.027)and increased length of hospital stay(P=0.045).However,no overall survival benefit was observed in group M.Furthermore,the immune function of patients in group M was less affected(P<0.001),when compared to that of patients in group L.The multivariate analysis suggested that the cycles of chemotherapy after perfusion significantly affected the prognosis of patients in both groups.CONCLUSION Compared to the lobaplatin-based HIPEC regimen,the administration of elemene reduced the myelosuppression incidence in elderly PGC patients.The present study sheds light on the implementation of this therapeutic strategy for this set of patients.
