Dose escalation and split course of 4-epidoxorubicin in combination chemotherapy (FEM II) of advanced gastric carcinoma. A phase-II trail of the 'Chemotherapiegruppe Gastrointestinaler Tumoren (CGT)'.

In a phase II trial 46 patients with advanced gastric carcinoma were treated with FEM combination chemotherapy (5-fluorouracil, 4-epidoxorubicin and mitomycin C) in which 4-epidoxorubicin was administered by escalated dose and split course (FEM II). Twenty-nine patients with measurable disease were evaluable for response. One complete remission and 7 partial remissions were achieved, suggesting an overall response rate of 28%; 2 minimal responses (7%) and 9 patients with no change were observed (31%); 10 patients had tumor progression (34%). Median survival time for all patients was 6.2 months, for patients with CR + PR + MR 16.2 months, for patients with no change 8.4 months, and with tumor progression 3.5 months. WHO grade 2 and 3 leukopenia appeared in 6%, thrombocytopenia in 0% and alopecia in 27% of the patients after the first cycle. Nausea and vomiting grade 2 and 3 were seen in 21%. Comparing these results with our earlier data achieved with FEM I, FEM II showed a tendency towards better response and survival, and subjective toxicity (nausea/vomiting) was significantly reduced. Therefore, in our opinion FEM II is preferable for practical use.
