Résumé : Thirty-four patients with measurable metastatic gastric adenocarcinoma refractory to prior chemotherapy were treated with cis-platinum 100 mg/m2 in a 6-hr infusion at 3-week intervals. Thirty-one patients were evaluable for response. There were three complete and three partial responses. Median duration of response was 4 months. Toxicity consisted mainly of nausea and vomiting and was severe in 12 patients. One patient had a severe but reversible renal failure. These results confirm other data reported in the literature. Cis-platinum has activity in gastric adenocarcinoma and should now be further investigated in first-line chemotherapy. © 1985.
