Context:
Purpose Adjuvant chemotherapy prolongs survival in patients with pancreatic cancer, but its benefit is limited. Long-term survival times of up to 44 months after adjuvant chemoradioimmunotherapy in phase II trials motivated the present study.
Patients and Methods Between 2004 and 2007, 132 R0/R1 resected patients received either fluorouracil (FU), cisplatin, and interferon alfa-2b (IFN a-2b) plus radiotherapy followed by two cycles of FU (arm A, n = 64) or six cycles of FU monotherapy (arm B, n = 68). One hundred ten patients (arm A, n = 53; arm B, n = 57) received at least one dose of the study medication, and these patients composed the per-protocol (PP) population. Biomarkers were analyzed longitudinally for their predictive value.
