[Formalization of clinico-topometric information in planning combined programmed gamma-therapy of endometrial cancer].

The paper is concerned with the problems of obtaining clinico-diagnostic and topometric information and its preparation for further computer-assisted use. Topometric schemes were made in the frontal, sagittal, and a series of transversal planes which permit assessment of the nature of ionizing radiation energy distribution in the main projection area of normal organs involved in the irradiated zone as well as within the limits of extended targets on the basis of optimized computer-assisted total dose distribution at the level of the tumor center. A dosimetric plan is regarded as a normal one if it meets the requirements of quality at all studied levels.

[Roentgenotopometric studies using a simulator during the preparation of patients with uterine cancer for irradiation].

During the examination of 170 patients with corpus and cervix uteri cancer it has been established that simulators give an opportunity to define orienting points in the same position as that used during irradiation, to obtain all necessary topometric data for preparing anatomotopographic maps and calculating with their help irradiation programs, and simulate geometric conditions of an irradiation program.

[Combined gamma-therapy of rectal cancer using movable radiation sources in intracavitary irradiation].

The authors present a technique of concomitant radiotherapy of rectal cancer using 60Co movable sources of the Agat-B unit for contact irradiation. The paper is illustrated with the schemes of radiation sources in relation to tumors and pictures of dose fields formed by various radiation sources and positions as well as their time intervals in each position during a therapeutic session. The results of treatment of patients in the main group (47 persons) and in the control group when the patients received gamma-beam therapy only (45 persons) are also given in the paper. Two-year survival rates have shown significantly improved long-term results in the main group. The new method is recommended for practical use as a variant for extended indications to concomitant radiotherapy of rectal cancer and for improving its results.
