BACKGROUND/AIMS: We performed retrospective study in order to compare oxaliplatin, leucovorin, and fluorouracil (FOLFOX) versus irinotecan, leucovorin, and fluorouracil (FOLFIRI) in recurred or metastatic gastric adenocarcinoma. METHODS: We investigated 56 patients who were diagnosed with recurred or metastatic gastric adenocarcinoma in a single center during march, 2003 to march, 2008. The patients received either FOLFOX or FOLFIRI chemotherapy. RESULTS: There were no significant difference between the Oxaliplatin group (30 patients) and Irinotecan group (26 patients) in sex, age, and ECOG performance (p>0.05). Oxaliplatin group showed 1 case of CR (3.3%) and 12 cases of PR (40%), making the response rate 43.3%. Irinotecan group showed CR in 2 cases (7.7%) and PR in 10 cases (38.5%), making the response rate 46.2%. The median value of time to progression was 4 months in the oxlaplatin group and 4.5 months in the irinotecan group. The overall survival showed no significant difference (p=0.784), with the irinotecan group (9.7 months) being slightly longer than the Oxaliplatin group (8.3 months). Grade 3/4 neutropenia occurred similarly in both groups (4 cases in the oxalplatin group, 9 in the irinotecan group). CONCLUSIONS: Both combination treatment can be used safely and effectively in recurred or metastatic gastric adenocarcinoma.

BACKGROUNDRegional intra-arterial infusion chemotherapy (RIAC) has been more valuable to improve prognosis and quality of life of patients with inoperable pancreatic adenocarcinomas, and adjuvant RIAC plays an important role in prolonging survival and reducing risk of liver metastasis after radical resection of pancreatic cancer, but the effect of preoperative or multiple-phase RIAC (preoperative combined with postoperative RIAC) for resectable pancreatic cancers has not been investigated. In this prospective study, the effect of multiple-phase RIAC for patients with resectable pancreatic head adenocarcinoma was evaluated, and its safety and validity comparing with postoperative RIAC were also assessed.
METHODSPatients with resectable pancreatic head cancer were randomly assigned to two groups. Patients in group A (n=50) were treated with new therapeutic mode of extended pancreaticoduodenectomy combined with multiple-phase RIAC, and those in group B (n=50) were treated with extended pancreaticoduodenectomy combined with postoperative RIAC in the same period. The feasibility, compliance and efficiency of the new therapeutic mode were evaluated by tumor size, serum tumor markers, clinical benefit response (CBR), surgical complications, mortality and toxicity of RIAC. The disease-free survival time, median survival time, incidence of liver metastasis, survival rate at 1, 2, 3 and 5 years were also observed. Life curves were generated by the Kaplan-Meier method.
RESULTSThe pain relief rate and CBR in group A was 80% and 84% respectively. Serum tumor markers decreased obviously and tumors size decreased in 26% of patients after preoperative RIAC in group A. No more surgical complications, mortality or severe systemic side effects were observed in group A compared with group B. The incidence of liver metastasis in group A was 34% which was lower than 50% in group B. The disease-free survival time and median survival time in group A were 15.5 months and 18 months respectively. The 1-, 2-, 3- and 5-year survival rates were 54.87%, 34.94%, 24.51% and 12.25% respectively. There was no significant difference of survival time or survival rates between two groups.
CONCLUSIONSMultiple-phase RIAC is effective in combined therapy of resectable pancreatic head carcinomas by enhancing inhibition of tumor growth and reduction of liver metastasis, without negative effect on patients' safety or surgical procedure.
