[Dose fractionation in photon and neutron therapy in the combined treatment of osteogenic sarcoma]. / Fraktsionirovanie dozy fotonnoi i neitronnoi terapii pri kombinirovannom lechenii osteogennoi sarkomy.

The paper is concerned with the clinical testing of irradiation fractionation in photon therapy, of which the optimum variant was worked out using a method of mathematical simulation. It was conducted in 30 patients with osteogenic sarcoma. In 5 cases a course of photon therapy was supplemented by neutron irradiation. Good tolerance of the proposed scheme by the patients, the absence of contraindications for its administration and marked antitumor efficacy were revealed. Radiation pathomorphism of osteogenic sarcoma after photon and neutron therapy was described.

[Working classification of spinal tumors and their surgical treatment]. / Rabochaia klassifikatsiia opukholei pozvonochnika i ikh khirurgicheskoe lechenie.

A working classification of vertebral tumors is discussed. The classification is based on tumor process expansion, presence of soft-tissue component and the degree of vertebral and neurologic complications. The extent and type of surgical procedure are determined in accordance with the authors' approach to tumor process staging.
