Celecoxib in Preventing Cancer in Patients at High Risk for Ovarian Epithelial Cancer Who Are Undergoing Prophylactic Oophorectomy

Molecular Alterations in Human Ovarian Epithelium Induced by Chemopreventive Agents in Patients at Elevated Inherited Risk of Ovarian Cancer: A Controlled Pilot Study in Ovarian Cancer Chemoprevention

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of celecoxib before prophylactic oophorectomy may be an effective way to prevent the development of ovarian epithelial cancer.

PURPOSE: A controlled pilot trial to study the effectiveness of celecoxib in preventing cancer in patients at high-risk for ovarian epithelial cancer who are undergoing prophylactic oophorectomy.

OBJECTIVES:

Primary

• Compare histologic and molecular alterations in tissue biomarkers of patients at high risk for ovarian cancer treated with celecoxib followed by prophylactic oophorectomy vs prophylactic oophorectomy only.

Secondary

• Compare alterations in gene expression pattern in patients treated with these regimens.

OUTLINE: This is a pilot study. Patients are assigned to 1 of 2 treatment groups.

• Group I: Patients receive oral celecoxib twice daily for 3 months and then undergo prophylactic oophorectomy.
• Group II: Patients undergo immediate prophylactic oophorectomy.

DISEASE CHARACTERISTICS:

• At high risk for ovarian cancer and meets criteria for 1 of the following:

  • Family history of at least 2 ovarian** or breast cancers* among the patient and first- or second-degree relatives in the same lineage

    • Multiple primary cancers in the same person may fulfill this requirement

  • Ashkenazi Jewish ethnicity AND 1 first-degree or 2 second-degree relatives with breast* or ovarian** cancer

  • Ashkenazi Jewish ethnicity AND had prior breast cancer*

  • BRCA1/BRCA2 mutation probability > 20% by BRCAPRO

  • Positive for BRCA1 or BRCA2 mutation

  • First- or second-degree relative with a BRCA1/BRCA2 mutation NOTE: *At least 1 breast cancer must be premenopausal (diagnosed at age 50 or under if menopausal status unknown); ductal carcinoma in situ qualifies as breast cancer

NOTE: **In relatives, only ovarian epithelial cancer, fallopian tube cancer, and primary papillary serous cancer qualifies as ovarian cancer

• No prior or concurrent ovarian cancer, including low malignant potential cancers or primary papillary serous carcinoma of the peritoneum

  • No clinical evidence of ovarian cancer by physical examination, CA 125 evaluation, and pelvic ultrasound
