Palliative MEFLEP therapy in advanced pancreatic cancer: excellent response in a patient with Her-2/neu amplification

INTRODUCTION: Patients with pancreatic cancer often present initially in advanced disease with many compromising factors, and yet they may still be responsive to chemotherapy. AIMS: The response of 23 patients with advanced pancreatic cancer to continuous infusion therapy was investigated. METHODOLOGY: From September 1995 to February 1998, 23 patients with advanced pancreatic cancer, many with compromising factors, were treated with a MEFLEP regimen: biweekly 24-hour infusions of etoposide, 5-fluorouracil, leucovorin, epirubicin, and cisplatin, all given through an infusion pump, plus megestrol acetate, 160 mg/d, taken daily. A total of 145 courses were given. Overall response rate was 21% (4/19) for assessable chemo-naive patients; median survival for all 23 patients was 6 months; 22% of patients were alive at 1 year; and a clinical response benefit was attained in 35%. RESULTS: Toxicity was manageable; grade 3 or 4 leukopenia occurred in 1 patient each, 1 patient had fever and grade 3 infection, and grade 3 and 4 hyperammonemic encephalopathy developed in 3 and 1 patients, respectively. All four of the latter patients recovered uneventfully within 2 days of initiation of therapy. Nine patients were evaluated by fluorescence in situ hybridization for the Her-2/neu oncogene, but for only one patient did amplification of the gene occur. She attained complete remission with treatment and lived for 26.7 months after diagnosis. CONCLUSION: Biweekly MEFLEP is an active and manageable regimen for patients with advanced pancreatic cancer with compromised clinical status.
