Luteinized Thecomas ("Thecomatosis") with Sclerosing Peritonitis (LTSP): Report of 2 Cases and Review of an Enigmatic Syndrome Associated with a Peritoneal Proliferation of Specialized (vimentin+/keratin+/CD34+) Submesothelial Fibroblasts.

Objective: To present the clinicopathologic features of two cases of luteinized thecomas with sclerosing peritonitis (LTSP), characterize the cellular proliferation in the sclerosing peritonitis (SP), and review the literature.

Methods: The clinical, laboratory, and imaging data, operative findings, and pathology materials were reviewed and summarized. Samples of the SP were stained with keratin AE1/AE3, vimentin, CD34, calretinin, smooth muscle actin, ER/PR, CD10 and desmin.

Risk of malignancy index in the evaluation of patients with adnexal masses.

Objective: To determine if the risk of malignancy index (RMI) can distinguish between benign and malignant adnexal masses in a population of women referred to a department of gynaecologic oncology for surgical resection of an adnexal mass.

Methods: We performed a retrospective review of the medical of charts of 259 consecutive patients. Ninety-six charts did not have data available to calculate the RMI, leaving a total of 163 for review.

Stage II endometrial carcinoma: limiting post-operative radiotherapy to the vaginal vault in node-negative tumors.

Objective: To evaluate the outcomes of patients with node-negative stage II endometrial cancer who received vault brachytherapy without external beam pelvic radiotherapy (EBRT).

Methods: A retrospective review of all stage II endometrioid type endometrial cancer patients referred to Cancer Care Manitoba was undertaken between October 1995 and March 2001. Forty-nine patients were identified with disease confined to the uterus, but not all patients received extended surgical staging (ESS) with pelvic lymphadenectomy.

High-risk surgical stage 1 endometrial cancer: outcomes with vault brachytherapy alone.

Objective: Prior to 1995, in our center, patients with surgically staged endometrial cancer with greater than 50% myoinvasion (FIGO 1C) were treated with vault brachytherapy and whole pelvis (WP) radiotherapy despite negative nodes. After October 1, 1995, these patients were treated with vault brachytherapy alone. The aim of this study was to ensure that the survival and recurrence rate had not changed.
