[A study of arterial infusion chemotherapy for gastric cancer patients with peritoneal metastasis]

We analyzed the clinical response, toxicities, out-patient and overall survival time among 41 gastric cancer patients with peritoneal metastasis to evaluate chemotherapies and drug delivery routes. Sixteen patients were treated by arterial infusion (AI) and 25 by systemic therapy (ST), with either 5-FU/MTX (FMTX) therapy or 5-FU/CDDP (FP) therapy. Partial response was observed in 8 patients (50%) among 16 with AI and in 6 (24%) among 25 with ST (p = 0.09). There were no differences in the incidence of side effects (> or = grade 2 according to WHO criteria) between AI and ST group, at 25% and 36%, respectively. No significant differences were observed in either survival time or home care duration among patients with AI chemotherapy and those with ST procedure.
