简要总结
RATIONALE: Screening tests may help doctors detect cancer cells early and plan more effective treatment for ovarian cancer.
PURPOSE: Screening trial to determine the significance of cancer antigen 125 (CA125) levels in detecting ovarian cancer in participants who have a high genetic risk of developing ovarian cancer.
详细描述
OBJECTIVES:
- Determine the feasibility of prospective ovarian cancer screening studies within the Cancer Genetics Network and other NCI ovarian programs for participants who are at high genetic risk for developing ovarian cancer.
- Identify the logistical issues of screening these participants and their solutions within this framework.
- Establish normal ranges and distributions of CA125 values over time within and between high-risk participants, with subclassification by pre- or post-menopausal status, estrogen-replacement therapy usage, and prior prophylactic oophorectomy.
- Estimate the specificity and positive predictive value of the "risk of ovarian cancer algorithm" (ROCA) suitable for designing a definitive trial of screening for ovarian cancer in high-risk participants.
- Establish a longitudinal serum and plasma biorepository for retrospective evaluation of other promising biomarkers with special relevance to inherited ovarian and breast cancer risk.
OUTLINE: This is a multicenter study. Participants with 1 or 2 ovaries are assigned to group A, whereas participants with prior prophylactic bilateral oophorectomy are assigned to group B (closed to accrual as of 10/18/04).
At baseline, participants who are not eligible by breast cancer susceptibility gene (BRCA) mutation criteria or family history criteria undergo a probability of having a BRCA mutation given family history of cancer (BRCAPRO) evaluation. Participants in both groups complete a questionnaire requesting demographic information and a personal and family health history at baseline and a questionnaire requesting hospitalization or cancer diagnosis information after each blood test. Participants in both groups also complete health status questionnaires once every 3 months for 6 months-7 years. Participants undergo blood draws for measurement of CA125 levels once every 3 months for 6 months-7 years. For each CA125 measurement, the risk of ovarian cancer algorithm (ROCA) is calculated.
Group A (1 or 2 ovaries at baseline):

入选标准
- •DISEASE CHARACTERISTICS:
- •Participant meet the criteria for one of the following conditions:
- •Participant has tested positive for a mutation in the breast cancer susceptibility gene 1 (BRCA1) or breast cancer susceptibility gene 2 (BRCA2) or has a first- or second-degree relative with a BRCA1 or BRCA2 mutation
- •At least 2 ovarian or breast cancers (including ductal carcinoma in situ) have occurred among the participant and her first- and second-degree relatives within the same lineage
- •Condition may be satisfied by multiple primary cancers in the same person
- •Where breast cancer is required to meet this criterion, at least 1 breast cancer patient must have been pre-menopausal (age 50 and under at diagnosis if age at menopause unknown)
- •Participant is of Ashkenazi Jewish ethnicity and either has had breast cancer or has 1 first-degree or 2 second-degree relatives with breast cancer (including ductal carcinoma in situ) or ovarian cancer
- •Where breast cancer is required to meet this criterion, at least 1 breast cancer patient must have been pre-menopausal (age 50 and under at diagnosis if age at menopause unknown)
- •Probability of carrying a BRCA1 or BRCA2 mutation exceeds 20% as calculated by BRCAPRO, given family pedigree of breast cancer (including ductal carcinoma in situ) and ovarian cancer
- •Participant must have no prior or concurrent ovarian cancer (including low malignant potential (LMP) cancers) or primary papillary serous carcinoma of the peritoneum
- •Participant must not be negative for the same BRCA1 or BRCA2 mutation for which a first- or second-degree relative has tested positive
- •Participants who test negative for BRCA1 or BRCA2 mutation are still eligible if the pedigree or BRCAPRO criteria are satisfied, including Ashkenazi women who test negative for the three founder mutations
- •Documentation of family history is by participant's self-report
- •In relatives, ovarian cancer is defined as invasive ovarian epithelial cancers, fallopian tube cancers, or primary papillary serous carcinoma of the peritoneum
- •Germ cell or granulosa tumors or LMP ovarian cancers do not qualify
- •First- and second-degree relatives include half siblings of the participant or her first-degree relative

- •PRIOR CONCURRENT THERAPY:
- •Biologic therapy:
- •Not specified
- •Chemotherapy:
- •At least 3 months since prior adjuvant anticancer chemotherapy
- •Endocrine therapy:

- •Radiotherapy:
- •At least 3 months since prior adjuvant anticancer radiotherapy
- •At least 3 months since prior intraperitoneal surgery (laparoscopy or laparotomy)
