Summary

The objective is to evaluate the efficacy and safety of carbon ion radiotherapy (CIRT) combined with nituzumab and gemcitabine in the treatment of locally advanced and metastatic pancreatic cancer.

Conditions

  • Pancreatic Cancer Metastatic
  • Pancreatic Cancer Non-resectable

Interventions

RADIATION

carbon ion radiotherapy (CIRT)

1.CIRT: GTV: Primary tumor visible on imaging and clinical examination, and involved regional lymph nodes identified by CT/MRI (≥1.0 cm) or PET/CT scan. CTV: GTV plus 5mm margin, include posterior peritoneal plexus area and elective node irradiation around the pancreas (ENI). PTV: CTV plus 2.5-5mm margin (depending on the system error of each unit; When pancreatic head cancer is close to the stomach and intestines, the gastrointestinal direction does not expand). ITV: delineated on 4D-CT considering the influence of respiratory activity. Prescription dose: Stratification by measuring the nearest distance between PTV and gastrointestinal tract (≥5mm or \< 5mm); Pancreatic head cancer (distance \< 5mm) : 52.8Gy(RBE)/4.4Gy/12Fx; Pancreatic head, body and tail cancer (≥5mm) : 57.2Gy(RBE)/4.4Gy/13Fx. CIRT was once a day, four or five times a week. 2.Chemotherapy:Gemcitabine 1000mg/m2, intravenous infusion, dl, d8; Q3w . 3.Targeted therapyNituzumab injection 400mg, Qw，at least 4-6 cycles.
