title: [The intraoperative irradiation of tumors].
abstract: Intraoperative irradiation of tumor was performed in 40 patients with cancer of the lung, stomach, breast, bone and soft tissues. It included irradiation of the bed of tumor removed. Fast electron beam was produced by a small betatron (collimator size--5 x 6 cm and 8 x 12 cm) installed in the operating room. Radiation was given to a single or to multiple fields in a single dose of 10-20 Gy to each field. Location of the radioactive source in the operating room proved technically, economically and medically advantageous since it was cheaper, assured a shorter period of the treatment and delivered from patient transportation to a radiotherapy department and ensuing complications. The procedure did not interfere with postoperative period. The efficacy of the treatment modality will be evaluated as soon as sufficient end results have been obtained.
