[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.
