[A case of liver metastatic recurrence of gastric cancer effectively treated by combined chemotherapy of CPT-11 and CDDP].

The patient was a 72-year-old female with gastric carcinoma. A liver metastatic recurrence was detected 27 months after operation. Although temporary partial responses were obtained by each effective chemotherapy, which was a combination chemotherapy with 5'-DFUR and TXT, TS-1 and TXL, the metastatic lesion proved refractory to all of them.

Prediction of sensitivity to fluoropyrimidines by metabolic and target enzyme activities in gastric cancer.

Background: This study was designed to investigate the role of thymidylate synthase (TS), dihydropyrimidine dehydrogenase (DPD), and thymidine phosphorylase (TP) in tumor progression and sensitivity to 5-fluorouracil (5-FU).

Methods: A total of 275 tumor samples from 275 patients with gastric cancer were utilized in this study. TS activity was determined in 130 samples by 5-fluorodeoxyuridine monophosphate binding assay.

[Combination chemotherapy with intra-perioneal infusion of CDDP and continuous intravenous infusion of 5-FU for peritoneal metastasis in gastric cancer--analysis of long-term survivors].

In order to evaluate the utility of combination chemotherapy with intra-peritoneal infusion of CDDP and continuous intravenous infusion of 5-FU, we performed this therapy in 23 primary gastric cancer patients with peritoneal metastasis. CDDP was administered intraperitoneally at a dose of 70 mg/m2 over 2 hours on day 1, and 5-FU was continuously administered intravenously at a dose of 700 mg/m2 for 5 consecutive days from day 1, respectively. This treatment was given twice.

Evaluation of the ratio of lymph node metastasis as a prognostic factor in patients with gastric cancer.

BACKGROUND: Lymph node metastasis in patients with gastric cancer is one of the important prognostic factors. However, there is no consensus concerning the best classification for lymph node metastasis as a prognostic factor. So, to evaluate the ratio of the number of metastatic lymph nodes to the total number of dissected lymph nodes (the ratio of LN meta) as a prognostic factor, we compared the ratio of LN meta with lymph node status according to the Japan Classification of Gastric Carcinoma and the total number of metastatic lymph nodes with multivariate analysis.
