Combination chemotherapy with epirubicin, docetaxel and cisplatin (EDP) in metastatic or recurrent, unresectable gastric cancer

Based on single agent activities and the additive or synergistic effects of three individual drugs in gastric cancer, we performed a phase II study of a new regimen combining epirubicin, docetaxel and cisplatin (EDP) for unresectable gastric cancer. The patients with histologically confirmed metastatic or recurrent, unresectable gastric cancer and no history of palliative chemotherapy were eligible for this trial. In total, 40 mgm(-2) epirubicin (reduced to 30 mgm(-2) due to high incidence of febrile neutropaenia; 75%) intravenously (i.v.) over 30 min, followed by 60 mgm(-2) docetaxel i.v. over 1 h, then 75 mgm(-2) cisplatin i.v. over 1 h was administered every 3 weeks. Between January 2002 and February 2003, 30 patients (epirubicin 40 mgm(-2), eight; 30 mgm(-2), 22) were enrolled. The median age was 52 years (range, 33-68). The patients received a median of four cycles (range, 1-8). One patient (3%) achieved a complete response, 13 (43%) showed partial responses, 13 (43%) had stable diseases and three (10%) progressed. The overall response rate was 47% (95% CI, 28-66%), and the median duration of response was 5.0 months (95% CI, 3.0-7.0). The median time to progression was 4.1 months (95% CI, 2.4-5.9), and the median overall survival was 11.0 months (95% CI, 9.5-12.4). Grade 4 neutropaenia were observed in 41%, and febrile neutropaenia in 32%, out of the patients receiving 30 mgm(-2) of epirubicin. Grade 3 nonhaematological toxicities included nausea, vomiting, anorexia and peripheral neuropathy. In conclusion, EDP is active in gastric cancer, with a manageable and predictable toxicity profile.
