BACKGROUND: To the authors' knowledge, there is no established second-line chemotherapy for patients with pancreatic cancer who have received gemcitabine-based therapy. A phase 2 trial was conducted to explore the efficacy of capecitabine and oxaliplatin (XELOX) in patients with advanced pancreatic cancer previously who were treated with gemcitabine. METHODS: Patients aged < or =" 65" style="border-bottom: 1px dashed rgb(0, 102, 204); cursor: pointer;" class="yshortcuts" id="lw_1225555975_9">Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 to 1 received oxaliplatin at a dose of 130 mg/m(2) given on Day 1 and capecitabine at a dose of 1000 mg/m(2) twice daily for 14 days. For patients aged >65 years or with an ECOG PS of 2, the oxaliplatin dose was 110 mg/m(2) on Day 1 and the capecitabine dose was 750 mg/m(2) twice daily for 14 days. The treatment was repeated every 3 weeks. Tumor measurements were performed every 9 weeks and the primary study objective was 6-month overall survival. RESULTS: The study enrolled 41 patients. Of the 39 evaluable patients, 1 patient had a partial response and 10 patients demonstrated stable disease. The Kaplan-Meier estimate of the overall median survival was 23 weeks (95% confidence interval [95% CI], 17.0-31.0 weeks). Progression-free survival was 9.9 weeks (95% CI, 9.6-14.5 weeks). The 6-month and 1-year survival rates were 44% (95% CI, 31%-62%) and 21% (95% CI, 11%-38%), respectively. The most common grade 3-4 nonhematologic toxicity was fatigue (toxicity was graded using the National Cancer Institute Common Toxicity Criteria [version 2.0]). CONCLUSIONS: The combination of capecitabine and oxaliplatin is active in gemcitabine-pretreated patients with advanced pancreatic cancer, especially in patients with a good PS and those who have responded to first-line chemotherapy.
