Phase II Trial of Weekly Docetaxel/Irinotecan Combination in Advanced Pancreatic Cancer
Cancer J. 2007 July/August;13(4) :257-262
AbstractBACKGROUND:: Docetaxel and irinotecan have activity in pancreatic cancer. The combination of docetaxel and irinotecan is attractive because of preclinical evidence of synergy between the two drugs. We have previously demonstrated the safety of docetaxel 35 mg/m and irinotecan 50 mg/m given on days 1, 8, 15, and 21 of a 35-day schedule. PATIENTS AND METHODS:: Patients who had unresectable or metastatic adenocarcinoma of the pancreas, bidimensionally measurable disease, Eastern Cooperative Oncology Group (ECOG) performance status 0-2, and normal bilirubin levels were eligible. Tumor assessment was performed with computed tomography, computed tomographic angiography, or magnetic resonance imaging every 2 cycles. Response was graded according to World Health Organization criteria. RESULTS:: We enrolled 37 eligible patients. Principal grade 3/4 toxicities were diarrhea (21%), neutropenia (30%), and hyperglycemia (30%). There were 3 patients with febrile neutropenia and no toxic deaths. There were 4 early deaths. Among 36 evaluable patients, 9 (24%) attained a partial response and 1 (3%) attained a complete response for an objective response rate of 27%. One patient enrolled because she had been deemed to have unresectable disease but then underwent resection with negative margins after attaining a confirmed partial response. Median survival for all eligible patients is 9.4 months (range 0-68+ months) with minimum follow-up for surviving patients of 23.4 months. One-year survival is 43%. The patient who attained a complete response is alive with recurrent disease at 68 months. CONCLUSIONS:: The docetaxel/irinotecan combination given on a weekly schedule is an active treatment for advanced pancreatic cancer.
