Postoperative treatment with docetaxel, cisplatin, and capecitabine (DCX) and chemoradiotherapy (CRT) with capecitabine for resected gastric adenocarcinoma.

INTRODUCTION: We conducted a feasibility study on docetaxel/capecitabine/cisplatin (DCX) with chemoradiotherapy as adjuvant treatment for gastric cancer patients. METHODS: Patients were scheduled to receive 2 cycles of DCX, followed by 50.4 Gy plus capecitabine as radiotherapy, followed by an additional 2-DCX cycles. RESULTS: From the 40 enrolled patients, 26 (65%) completed treatment as per protocol and 14 (35%) discontinued with the treatment (patients' refusal: n=6; adverse events: n=8). There were 2 toxic deaths. Grade >3 toxicity was 12.1% before and 13.3% after chemoradiotherapy. Disease progression was documented in 11 (27.5%) patients. CONCLUSIONS: No further development of this regimen is justified on the basis of poor tolerability in patients.
