Docetaxel and Capecitabine in Advanced Gastric Cancer

Patients with locally advanced or metastatic gastric adenocarcinoma who did not receive any prior chemotherapy for advanced disease can be enrolled in the study.

Patients are treated with oral capecitabine 1000mg/sqm twice per day on the days 1-14 and docetaxel 75 mg/sqm on day 1 as a 1 hour i.v. infusion. chemotherapy is repeated every 21 days. Staging by imaging is performed every 2 cycles.

After 40 included patients an amendment was done and the starting of chemotherapy has been reduced to further improve tolerability. Starting dose of docetaxel was amended to 60 mg/sqm, d1, and starting dose of capecitabine reduced to 800 mg/sqm twice per day, d1-14. The patient number to be included was increased to 70 pts.

Therapy is continued up to tumor progression to a maximum of 10 cycles. Therapy is stopped in case of severe side effects, tumor progression or withdrawal of consent.

This investigator initiated study is supported by Hoffmann-La Roche and by Sanofi-Aventis.
