We reviewed our experience with 81 patients who had undergone followup needle biopsies of the prostate between 12 and 27 months after 192iridium template radiotherapy combined with external beam radiation therapy. When broken down by stage 82% of the patients with stage A2, 92% with B1, 95% with B2 and 55% with C disease demonstrated a negative biopsy and adequate local control of the cancer. We believe that in elderly patients, poor risk patients with early stage disease and stage C lesions this low morbidity, low mortality therapy offers a viable option to other modalities of treatment.

Background: Interstitial accelerated partial breast irradiation is generally limited to patients with extremely low risk of local recurrence.
Materials And Methods: Between 2004 and 2008, 53 women in the early-stage of breast cancer were treated with multicatheter interstitial brachytherapy in very short general anaesthesia. All patients had T1 (1-22 mm) tumour with no positive auxiliary node and with negative surgical margins.
The use of fluoroscopy to guide needle placement in interstitial gynecological brachytherapy.

Purpose: Interstitial brachytherapy is generally performed for gynecological malignancies with extensive parametrial involvement, by inserting the needles through a transperineal template. Often, the implanted needles are not parallel, and the multiple sources can be difficult to identify on localization radiographs, especially if obtained with a portable X-ray unit. We have used fluoroscopy to guide the needles for interstitial brachytherapy to treat various gynecological malignancies.

Vaginal cancer is highly curable in all stages by combining the proper interstitial or intracavitary endocurietherapy (ECT) techniques and external beam radiation therapy (EXRT). Each case must be individualized following careful evaluation of stage and local extent of disease. We describe three afterloading ECT techniques used for treatment of various presentations of vaginal cancer: 1) 137cesium vaginal obturator used for superficial lesions; 2) afterloading 192iridium tube and button technique used for localized lesions of the lower one-third of the vagina which do not involve more than one-half of the circumference; and 3) afterloading transperineal interstitial 192iridium template technique used for thick invasive lesions of the upper two-thirds of the vagina.

Two afterloading techniques of endocurietherapy are used, first, the intracavitary technique with 137Cesium, and second, the interstitial technique with 192Iridium. Because of displacement of the bladder and rectum away from the applicator in intracavitary ECT, compared to interstitial ECT where vaginal packing cannot be used, the rectal and bladder reference point doses are much lower.
