gemcitabine and capecitabine with or without t-chos as adjuvant therapy for patients with resected pancreatic cancer

Conditions: Pancreatic Cancer

Summary: this is a single center, randomized, double-blind, placebo-controlled phase ii trial that will compare the efficacy of t-chos in combination with gemcitabine to gemcitabine alone as adjuvant treatment for 6 months in patients with surgically resected pancreatic adenocarcinoma.
