SBRT, Locally Advanced Pancreatic Cancer, Biological Effective Dose
Brief summary
The aim of this study is to compare the safety and efficacy of SBRT in LAPC with different biological effective dose (BED) (\<70Gy Vs.\>70Gy ) , to identify a dose range that could achieve better survival benefit and minimize the toxicity of radiotherapy.
Interventions
SBRT: in 5-6 fractions with CyberKnife
Gemcitabine 1000mg/m\^2 and nab-paclitaxel 125mg/m\^2, administered intravenously, on day 1 and 8 of a 21-day cycle for six cycles
