[The third report from Sapporo Tsukisamu Hospital--chemotherapy for patients with advanced gastric cancer (peritoneal dissemination, peritonitis carcinomatosa)].
Recently, it became possible to reduce the size of tumors in patients with advanced or relapsed gastric cancer by chemotherapy with the combination of several kinds of anti-cancer drugs which are all effective and allowed for use with gastric cancer patients. However, chemotherapy alone can not cure patients with advanced gastric cancer that was shown to improve median survival time (MST), compared with patients provided with the best supportive care (BSC). According to reports from Europe, US and Japan,the MST of patients with advanced gastric cancer and those with peritoneal expansion treated by chemotherapy is almost 7-12 months and 5-6 months,respectively, both of which are short and unsatisfactory. From March 2002, we started to treat patients with advanced gastric cancer (stage IV) with a new regimen; intermittent dosage of 5-FU (-->S-1), CDDP and paclitaxel utilizing the difference of cell cycle between normal and cancer cells (intermittent FP . weekly PTX). In the present study, therefore, we analyzed advanced gastric cancer patients with peritoneal expansion (9 cases, 4 with cancerous peritonitis) treated with this regimen. The results were as follows. The one-and 2-year survival rate was 55.6% and 27.8%, respectively, and the MST was 14 months. Four patients (44.4%) had hematological toxicities over grade 3. All of them had anemia (3 cases) and neutropenia (3 cases). Toxicities of thrombocytopenia were all under grade 1 and nonhematological toxicities were all under grade 2, which were clinically manageable. These results, although the sample was small, suggested that this may contribute to the extension of survival time of patients with stage IV advanced gastric cancer with peritoneal expansion.
