[Intraoperative radiation treatment of carcinoma of the pancreas. Initial clinical results].

Intraoperative radiotherapy (IORT) was administered to 13 patients with carcinoma of the pancreas, using high-velocity electrons of a LINAC accelerator in a single dose of maximally 25 Gy applied directly to the tumour or tumour bed with the abdomen open. There were no disorders of wound healing or other serious early complications which could be ascribed to the radiation. Stomach and intestines were excluded from the radiation field to avoid late radiation damage, such as stenoses or ulcers. The method is particularly indicated for locally non-resectable, non-metastasized pancreatic carcinoma, possibly also as tumour-bed radiation during radical surgery. Patients with distant metastases were not given radiation. First results point to IORT providing lasting improvement of pancreatic pain. It is too early to know whether survival time is favourable influenced.
