OBJECTIVE: To investigate the complications in intra-operative radiotherapy (IORT) for patients with local advanced pancreatic cancer.
METHODS: The clinical data, operation material, overall dose of IORT, postoperative therapy, complications, treatment and prognosis were retrospectively analyzed in all the in-hospital pancreatic cancer patients from Nov 2008 to Jan 2012.
RESULTS: There were 115 patients with local advanced pancreatic cancer treated with IORT in this study. 81 cases had a tumor in the head of pancreas and 34 cases in the pancreatic body and tail. The operation method was IORT combined with internal drainage surgery. The intra-operative radiotherapy was performed using Mobetron mobile electron accelerator, with a total dose of 12-20 Gy. Bilioenteric anastomosis and/or gastrointestinal anastomosis were included in the internal drainage surgery. Gastroparesis syndrome (10.4%), hemorrhage (3.5%), abdominal infection (2.6%), pancreatic fistula (0.9%) and renal failure (1.7%) were the common postoperative complication of IORT. All patients were cured except one who died of digestive tract hemorrhage.
CONCLUSIONS: Major complications of IORT are gastroparesis syndrome, abdominal infection and hemorrhage. The incidence of gastroparesis syndrome is at the top of the list. However, early complications have a relatively better prognosis, indicating that IORT is a safe and reliable therapy for patients with locally advanced pancreatic cancer.
