Dosimetric Analysis of Vaginal Cuff Brachytherapy in Endometrial Carcinoma

Completed

• Conditions: Endometrial Carcinoma; Cervix Cancer; Carcinoma of the Uterus

• Registration Number: NCT00165126
• Lead Sponsor: Dana-Farber Cancer Institute

Brief Summary

The purpose of this study is to investigate the effect of certain variables such as the fullness of the patients bladder and the position of the treatment applicator on the dose of radiation that other organs such as the bladder and the rectum receive during radiation treatment for endometrial carcinoma.

Detailed Description

* This study is separated into 2 phases. In phase 1, patients will be asked to have their bladder full for the second planned insertion of the brachytherapy applicator and empty for the third insertion. For phase 2, the effect of cylinder angle on normal tissue dosimetry will be investigated. Of the two bladder states assessed in phase 1 (empty or full), the one deemed to give the lower dose to the total amount of bladder tissue will be considered the standard and applied to all patients in phase 2.

* In phase 1, to standardize bladder filling, patients will be asked to empty their bladder, then to drink 32 oz of water one and a half hours before the CT scan. The patient will undergo a treatment-planning scan after the brachytherapy cylinder is inserted and before brachytherapy treatment.

* In phase 2, patients will be asked to fill or empty their bladder according to the results of phase 1. The vaginal cylinder will be placed horizontally for the second treatment. The cylinder will then be angled at a specific angle for the subsequent treatment.

* A history and physical exam will be performed within 2 weeks of study entry, then at 14 days, 90 days, and 180 days following the completion of therapy.
