Objective To investigate the factors affecting the survival and prognosis of patients with stage Ⅲ～ Ⅳgastric cancers.Methods A total of 156 cases of Ⅲ ～ Ⅳ gastric cancer was studied retrospectively from September 1,2006 to December 31,2012.Kaplan-Meier analysis,Log-rank univariate analysis,Cox proportional hazards model analysis were used to analyze survival and prognostic factors.Results Twelve cases were lost,to the end of the follow-up,22 cases were alive.The median survival time was 29.3 months.1-year,3-year,and 5-year overall survival rates were 83.3％,37.8％,and 21.2％,respectively.Univariate analysis showed that tumor size,tumor node metastasis (TNM) staging,curative resection,hyperthermic intraperitoneal perfusion chemotherapy (HIPEC),and postoperative chemotherapy were correlated with prognosis (P ＜0.05 for all).Multivariate analysis showed that TNM staging,curative resection,HIPEC,and postoperative chemotherapy were independent prognostic factors (P ＜ 0.01 for all).Conclusions TNM staging,curative resection,hyperthermic intraperitoneal perfusion chemotherapy and postoperative chemotherapy are the independent factors affecting the prognosis of stage Ⅲ～ Ⅳ gastric cancer after resection.Hyperthermic intraperitoneal perfusion chemotherapy and postoperative chemotherapy can improve their survival.

Objective To investigate the efficacy of precise hyperthermic intraperitoneal perfusion chemotherapy (HIPEC) in the treatment of advanced pancreatic cancer.Methods Thirty-six patients with advanced pancreatic cancer were analyzed retrospectively.Eighteen patients who received HIPEC combined with radiotherapy and chemotherapy were assigned as the treatment group and the other 18 patients who received chemotherapy and radiotherapy were assigned as the control group.Recent curative efficacy,Karnofsky Performance Status (KPS) score,postoperative complications and survivals between the two groups were analyzed,respectively.Results Significant differences were found between two groups in total short-term effective rate (P ＜ 0.05).The total short-term effective rate of treatment group and control group were 66.67％ (12/18) and 27.78％ (5/18),respectively.The increment of KPS score of treatment group was significantly higher than that of control group (P ＜ 0.05).There was no significant difference between two groups in postoperative complications (P ＞ 0.05).The median overall survival time (OS) of treatment group was 11 months (7 ～ 31 months),and the median OS of control group was 7 months (4 ～ 18 months).The survival of the treatment group was longer than the control group (P ＜ 0.05).Conclusions HIPEC treatment improved significantly the survival and life quality of advanced pancreatic cancer patients.With acceptable morbidity and mortality rates,HIPEC regime was an effective treatment modality for patients with advanced pancreatic cancer.

Objective To investigate the clinical efficacy and safety of hyperthermic intraperitoneal perfusion chemotherapy (HIPC) in treatment of advanced colorectal cancer.Methods The Meta-analysis was applied to analyze 8 randomized controlled quantitative studies published at domestic and abroad.These patients treated by HIPC after radical operation with colorectal cancer were included for the treatment group,and those treated only by radical operation with colorectal cancer for the control group.Relative risk (RR) of outcome variable of 3-year and 5-year survival rate and safety between the two groups were compared.Results There were 8 selected literatures,including 1 501 cases,in which 765 cases for treatment group,and 736 cases for control group.RR of 5-year survival rate of the total patients was 2.39 (95% CI:1.66-3.45).RR of 3-year survival rate of the total patients was 2.13 (95% CI:1.45-3.13).The results demonstrated that HIPC could improve 5-year and 3-year survival rate,and sensitivity analysis confirmed the conclusions more reliable.The security was described in 5 literatures,the available information showed smaller potential security issue.Conclusions HIPC after radical operation of advanced colorectal cancer can increase 5-year and 3-year survival rate of patients,improve the prognosis of patients.Whether patients with increased incidence of postoperative complications related to the HIPC is no clear-cut conclusions for lack of related research.

Objective To evaluate laparoscopic continuous circulatory hyperthermic intraperitoneal chemotherapy (CHIPC) in the treatment of malignant ascites from peritoneal carcinomatosis.Methods From March 2006 to March 2008, 21 patients of malignant ascites secondary to peritoneal carcinomatosis received CHIPC with three courses of treatment for each patient. The first course was performed in operation room under general anesthesia, the second and third were performed in patients ward or intensive care unit (ICU), NS solution of mitomycin-C and cisplatin was delivered by continuous circulatary perfusion into peritoneal cavity at a rate of 500 ml/min for 90 min with an inflow temperature of 43 degrees C. Results Intraoperative course was uneventful in all cases, and mean operative time was (80 ± 18) min. There was no postoperative deaths and severe complications. After treatment patients KPS KPS (Karnofsky,KPS)grades rose from 10-40, with an average rise of (22.2 ± 2.4) (P ＜ 0.01). After laparoscopic CHIPC, clinical complete regression of ascites and related symptoms was achieved in 19 patients, and partial remission achieved in 2 patients. Follow-up was made to all patients until the death which occurred at post laparoscope-assisted CHIPC 1 - 9 months, with a median survival time of 6 months.Two patients who underwent partial remission suffered from port site seeding and tumor metastasis leading to death after treatment at 1 and 2 months respectively. Conclusions Laparoscopy-assisted CHIPC is effective for the treatment of malignant ascites from inoperable peritoneal carcinomatosis and improves the quality of life of these patients.

Objective To investigate the measurement , feasibility and clinic effect of hyperthermic intraperitoneal chemotherapy (HIPEC) guided by B ultrasound in the treatment of malignant ascites from peritoneal carcinomatosis. Methods From July 2011 to June 2013, B ultrasound-guided approach was used to perform HIPEC on 36 patients affected by malignant ascites secondary to peritoneal carcinomatosis. Every patient underwent HIPEC for three times , by way of continuous circulatory perfusion into peritoneal cavity with saline at 400 ~ 600 mL/min and intraperitoneal perfusion with 5-FU mitomycin-C and cisplatin for 90 minutes with an inflow temperature of (43 ± 0.2)℃. These patients were followed up for a long term. Results Intraoperative course was uneventful in all cases. Complete clinical regression of ascites and related symptoms was achieved in all the 26 patients, partial regression achieved in 8 patients, and no curative effect achieved in 2 cases. The acquired total clinic effectiveness was 94.44%. No postoperative deaths and complication related to the procedure occurred in this study. The KPS grades of patients rose (P < 0.001), the level of tumor markers decreased, including CA199 (P < 0.001), CEA (P < 0.001), CA125 (P = 0.003). Conclusion HIPEC guided by B ultrasound appears to be a safe, feasible and effective procedure for the treatment of debilitating malignant ascites from unresectable peritoneal carcinomatosis , which would have a clinic good perspective in future.
