Official title

A Randomized Controlled Pilot Trial of Vitamin D3 Replacement of Placebo Followed by Bilateral Salpingo-Oophorectomy for Women at Increased Risk of Developing Ovarian, Fallopian, or Primary Peritoneal Cancer.

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this research is to study Vitamin D3 replacement for patients at high risk of developing ovarian, fallopian tube, or peritoneal cancer, and see if the Vitamin D3 replacement may be able to prevent the cancer. This study is being done because in the United States ovarian cancer is the leading cause of death among women with gynecologic cancer. Women with BRCA mutations, a personal history of breast cancer, and a family history of breast and ovarian cancer are at high risk of developing ovarian, fallopian, and primary peritoneal cancer. Novel treatments other than surgery which can decrease the risk of developing ovarian, fallopian tube, and primary peritoneal cancer are important. Vitamin D has been shown to reduce the risk of developing bladder, breast, colon, endometrial, esophageal, gallbladder, gastric, lung, pancreatic, prostate, rectal, renal, vulvar and Hodgkin and non-Hodgkin lymphoma, and it may play a role in the prevention of ovarian cancer.
