Overview
Brief Summary
This phase II trial chose the induction chemotherapy with gemcitabine and cisplatin followed by Chemoradiotherapy (CRT) with gemcitabine to optimize the treatment for pancreas cancer patients with locally advanced disease and the purpose of this trial is to evaluate the efficacy of induction CT with gemcitabine and cisplatin followed by CRT for unresectable pancreatic carcinoma.
Detailed Description
The primary endpoint is feasibility and compliance of induction chemotherapy with gemcitabine and cisplatin followed by CRT for locally advanced unresectable pancreatic cancer. Previous studies showed that approximately 20% of patients with locally advanced disease developed the early distant metastasis.\[6, 7\] Thus, it will be expected that at least 80% of total patients will be eligible for induction chemotherapy after completion of induction chemotherapy. An experimental arm that result a compliance of 80% would merit further study. If the true compliance rate of the patients who will eligible for CRT is ≤ 60%, null hypothesis will be rejected with a power of 80% and a type I error of 5%. Thus, the required number of evaluable patients is 24. Considering the 10% follow-up loss and 20% distant metastasis rate after induction chemotherapy, a total of 34 eligible patients will be enrolled.
