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

RADIATIONSBRT

SBRT: in 5-6 fractions with CyberKnife

DRUGChemotherapy

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
