Chemotherapy significantly improves survival in comparison to best supportive care. In addition, combination chemotherapy improves survival compared to single-agent 5-FU. All patients should be tested for their HER-2 status and trastuzumab should be added to a standard fluoropyrimidine/cisplatin regimen in patients with HER-2 positive tumours. Two and three-drug regimens including 5-FU, cisplatin, with or without an anthracycline, as well as irinotecan or docetaxel-containing regimens are reasonable treatment options for HER-2 negative patients.
[A randomized controlled trial with methotrexate (MTX), 5-fluorouracil (5-FU) and pirarubicin (THP) vs 5-FU alone in advanced or recurrent gastric carcinoma. Tokai Hokuriku THP Study Group].
A randomized controlled trial was designed to investigate the therapeutic benefit of a combination chemotherapy consisting of MTX, 5-FU and THP in patients with advanced or recurrent gastric carcinoma. The patients were randomized into two groups; Group A patients (n = 37) underwent our combined chemotherapy, whereas Group B (n = 34) underwent chemotherapy with 5-FU alone as a control. There were no significant differences in various background factors between the groups. The median survival time was roughly 170 days after the randomization for the patients with advanced cancer (n = 26 for Group A and n = 25 for Group B), with no significant difference between the groups. Two long survivors, however, belonged to Group A. The median survival time of 161 days for Group A (n = 11) was longer than that of Group B (84 days, n = 9), but the difference was not statistically significant. The incidence of toxicities (leukopenia in particular) exceeding JCOG grade 3 was significantly higher for Group A, but no morbidity was observed. These results imply that patients with advanced or recurrent gastric carcinoma may benefit from a regimen of MTX, 5-FU and THP.
