Etoposide, adriamycin, and cisplatinum (EAP) combination chemotherapy for advanced gastric cancer. A phase II trial by the "Chemotherapiegruppe Gastrointestinaler Tumoren (CGT)".
In a multicenter trial, 49 patients with histologically proven advanced gastric cancer were treated with a combination chemotherapy consisting of etoposide 120 mg/m2 d 4, 5, 6 adriamycin 20 mg/m2 d 1, 7 and cisplatinum 40 mg/m2 d 2, 8. Therapy was repeated every 4 weeks, 45 patients were evaluable for response after 8 weeks of treatment. Eight patients achieved a partial remission (PR: 18%), 17 patients had no change (NC: 38%), and 20 patients showed tumor progression (P: 44%). Four patients with primarily inoperable tumor and without distant metastases who achieved a partial remission, underwent second look operation with curative intention. All 4 patients died within 12 months after second look operation due to tumor recurrence. Median survival time of all patients was 9 months. Toxicity was considerable. WHO grade 3/4 toxicity appeared in 20-30% of patients (nausea, vomiting, loss of appetite, leucopenia). After 3 cycles complete alopecia was present in 70% of patients. Severe infection, requiring treatment, occurred in 10 patients. Five patients discontinued therapy because of intolerable subjective toxicity. The observed response rate of 18% objective partial remissions is disappointing and does not give support to the communications reporting response rates over 50% with EAP and other regimens including cisplatinum. In conclusion, and considering the high subjective and objective toxicity of this regimen, it can not be recommended for standard use in patients with advanced gastric cancer.
