Cost-effectiveness analysis of prevention strategies for gynecologic cancers in Lynch syndrome.

Background: Women with Lynch syndrome (hereditary nonpolyposis colorectal cancer) have an increased lifetime risk for endometrial and ovarian cancer. Screening and prophylactic surgery have been recommended as prevention strategies. In this study, the authors estimated the net health benefits and cost-effectiveness of these strategies in a Markov decision-analytic model.

Prospective determination of prevalence of lynch syndrome in young women with endometrial cancer.

Purpose: Age younger than 50 years at the time of colon cancer diagnosis is often used as a screening criterion for Lynch syndrome (hereditary nonpolyposis colorectal cancer syndrome). The purpose of this study was to determine the prevalence of MLH1, MSH2, and MSH6 mutations in an unselected cohort of women diagnosed with endometrial cancer at age younger than 50 years.

Methods: A prospective, multicenter study was performed at three institutions.

Prophylactic bilateral salpingo-oophorectomy compared with surveillance in women with BRCA mutations.

Objective: The objective of this study was to evaluate clinical factors associated with choosing prophylactic bilateral salpingo-oophorectomy (BSO) over surveillance in women with a BRCA1 or BRCA2 mutation.

Methods: Between 1996 and 2005, 139 women who tested positive for a BRCA1 or BRCA2 mutation were identified. Thirty-three women were excluded due to a personal history of ovarian or fallopian tube cancer before genetic testing, resulting in 106 women for the final analysis.

Prophylactic surgery to reduce the risk of gynecologic cancers in the Lynch syndrome.

Background: Women with the Lynch syndrome (hereditary nonpolyposis colorectal cancer) have a 40 to 60 percent lifetime risk of endometrial cancer and a 10 to 12 percent lifetime risk of ovarian cancer. The benefit of prophylactic gynecologic surgery for women with this syndrome has been uncertain. We designed this study to determine the reduction in the risk of gynecologic cancers associated with prophylactic hysterectomy and bilateral salpingo-oophorectomy in women with the Lynch syndrome.

Pathologic features of endometrial carcinoma associated with HNPCC: a comparison with sporadic endometrial carcinoma.

Background: Endometrial carcinoma is a common malignancy in hereditary nonpolyposis colorectal carcinoma (HNPCC). Like colon carcinoma, endometrial carcinoma is diagnosed at an earlier age in women with HNPCC. In contrast to colon carcinoma, the pathologic features of endometrial carcinoma in HNPCC have not been studied in detail.
