[Combined neutron and gamma-therapy of tongue cancer].

The authors conducted a comparative study of the electivity of various schemes of interstitial therapy with 252Cf of 37 tongue cancer patients with tumors corresponding to the clinical stage T2N0M0. The immediate, short- and long-term results of contact neutron therapy alone, by the conventional scheme of combined therapy and a new method were assessed. Interstitial neutron therapy of a primary tumor was given at the first stage, gamma-beam therapy of a primary focus and regional metastatic zones was given at the second stage.

Californium-252 interstitial implants in carcinoma of the tongue.

A clinical study using 252Cf sources in brachytherapy of tumors began in the Research Institute of Medical Radiology of the Academy of Medical Sciences of the USSR in 1973. 252Cf afterloading cells were utilized by the method of simple afterloading. Dosimetry and radiation protection of medical personnel were developed.
