This study is to investigate whether neoadjuvant chemotherapy plus SBRT results in better outcomes compared with neoadjuvant chemotherapy alone and also compare the efficacy of gemcitabine plus nab-paclitaxel with SBRT and S-1 plus nab-paclitaxel with SBRT.
This research study is a Phase II clinical trial that investigate whether neoadjuvant chemotherapy plus SBRT results in better outcomes compared with neoadjuvant chemotherapy alone and also compare the efficacy of gemcitabine plus nab-paclitaxel with SBRT and S-1 plus nab-paclitaxel with SBRT. It is known that neoadjuvant therapy is vital for improved survival, which has been confirmed in previous studies that neoadjuvant chemotherapy with or without radiotherapy provides superior overall compared with upfront surgery. However, question of whether the addition of radiotherapy to neoadjuvant chemotherapy can improve prognosis compared with chemotherapy alone is a challenging matter. Also, no studies have evaluated the efficacy of S-1 as the neoadjuvant chemotherapy regimen for BRPC albeit similar prognosis has been found between S-1 and gemcitabine in advanced pancreatic cancer. In this trial, patients with biopsy and radiographically confirmed BRPC will be randomly allocated into three groups: neoadjuvant gemcitabine plus nab-paclitaxel, neoadjuvant gemcitabine plus nab-paclitaxel with SBRT and neoadjuvant S-1 plus nab-paclitaxel with SBRT. Surgical resection will be performed 3 weeks after SBRT. The primary endpoint is overall survival. The secondary outcomes are progression free survival, pathological complete response rate, R0 resection rate and incidence of adverse effects. If results show the survival benefits of neoadjuvant chemotherapy plus SBRT and similar outcomes between S-1 and gemcitabine, it may provide evidence of clinical practice of this modality for BRPC.

Neoadjuvant gemcitabine plus nab-paclitaxel is used in the intervention group for 3 cycles. Standard doses of gemcitabine and nab-paclitaxel are adopted. Surgical resection will be performed after neoadjuvant chemotherapy.
Neoadjuvant gemcitabine plus nab-paclitaxel with SBRT is used in the intervention group for 3 cycles. Standard doses of gemcitabine and nab-paclitaxel are adopted. The radiation dose of SBRT is 7.5-8Gy/f for 5 fractions. Surgical resection will be performed 3 weeks after SBRT.
