Uterine thickness determination using real-time ultrasonography: A guide for intracavitary brachytherapy in the treatment of endometrial carcinoma

Two patients with medically inoperable stage I endometrial carcinoma were treated with intracavitary implants alone using Simon capsules, tandems, and ovoids. In both cases, uterine thickness was measured during the implant procedure by real-time ultrasonography. Tumor doses in both patients were then calculated to the midmyometrium and to the serosal surface of the uterus. These estimates, rather than the usual milligram-hours or points A and B, were used to make treatment decisions.
