[Interstitial gamma therapy of recurrences and metastases of cancer of the uterus and rectum to the vagina].

The authors devised a technique of interstitial radiation therapy for locally disseminated vaginal recurrences and metastases that occur after the use of various therapeutic methods for uterine and rectal cancer. Indications and counterindications to interstitial radiation therapy with 60Co as an independent method or the main therapeutic component in combined or multimodality treatment, were determined. Methods of the topometric and dosimetric planning of treatment, methods of needle administration and fixation by the system of manual afterloading were developed. Interstitial radiation therapy was given to 22 patients with a complete tumor regression in 17 of them. Interstitial radiation therapy is recommended as a method of choice for the therapy of vaginal recurrences and metastases.
