Background: Patients with metastatic gastric adenocarcinoma have a relatively poor prognosis with a median survival of 6 months. The three-drug regimen of docetaxel, oxaliplatin, and fluorouracil (DOF) has been shown to improve survival compared to the two-drug regimen of docetaxel and oxaliplatin with similar toxicity. However, there is no published Indian experience with this regimen. Aim: The aim of this study was to evaluate the efficacy in terms of progression-free survival (PFS) and overall survival (OS) of DOF regimen for metastatic gastric adenocarcinoma patients in Indian settings. Materials and Methods: All patients with metastatic gastric adenocarcinoma who were treated with DOF regimen chemotherapy at our tertiary care center in North India from 2014 to 2018 were retrospectively reviewed. The DOF regimen consisted of docetaxel 50 mg/m2 on day 1, followed by oxaliplatin 85 mg/m2 on day 1, and 5-FU 2400 mg/m2 continuous intravenous infusion over 46 h; (cycle repeated at two weekly intervals until progression or unacceptable toxicity). The endpoints were overall response rate (ORR), PFS, and OS, which were evaluated using Kaplan–Meier analysis. Results: Fifteen patients with a median age of 52 years were identified; 73% were male. ORR was seen in 86.7% of patients (complete response: 20%, partial response: 60%, and stable disease: 6.7%) and progressive disease was seen in 13.3% of patients. With a median follow-up of 14 months, the median PFS was 7 months and the median OS was 16 months from the start of therapy. One-year PFS was 22% and 1- and 2-year OS was 79% and 26%, respectively. The most frequent Grades 3–4 adverse events in our patients being mucositis (33.3%), neutropenia (26.7%), and diarrhea (20%). Conclusion: DOF regimen is an effective and feasible regimen in patients with metastatic gastric cancer.
