Abstract

Background: Platinum-based chemotherapy is the standard treatment for advanced gastric cancer (GC). This trial explored the efficacy and tolerability of combined docetaxel (Taxotere) + oxaliplatin (DOCOX) in GC patients.

Patients and methods: Patients with untreated stage IV GC or adenocarcinoma of the gastroesophageal junction (AGEJ) received docetaxel 60 mg/m(2) followed by oxaliplatin 130 mg/m(2) on day 1 of each 21-day cycle until progression or unacceptable toxicity. The primary end points were response rate (RR), toxicity, progression-free survival (PFS), and overall survival (OS).

Results: Baseline characteristics (N = 71): median age 59 years, 72% male, 51% esophagogastric junction cancer, and Eastern Cooperative Oncology Group performance status of zero, one, two were 42%, 51%, 7%, respectively. The median number of cycles was 6 (range, 1-19). Grades 3-4 toxic effects: neutropenia (70%); vomiting (17%); nausea (16%); dehydration, fatigue, or diarrhea (13%, each); and thrombocytopenia or febrile neutropenia (7%, each). Sixty-six patients completed >/=2 cycles. The RR was 36% with 25 partial response (PR) and no complete responses (CRs); stable disease (SD) was 49%. Clinical benefit rate (CBR = CR + PR + SD >/=6 months) was 40%; median PFS was 4.3 months, and OS was 8.5 months.

Conclusions: DOCOX produced manageable toxicity in patients with advanced GC and AGEJ. The confirmed RR of 36%, CBR of 40%, and median survival of 8.5 months are encouraging and comparable to standard front-line regimens.
