Abstract

OBJECTIVE:

To evaluate the relationship between use of fertility medication (i.e., selective estrogen receptor [ER] modulator, gonadotropin, or other) or infertility treatment (i.e., IVF or IUI) and the risk of ovarian cancer among women with a BRCA1 or BRCA2 mutation.

DESIGN:

A matched case-control study of 941 pairs of BRCA1 or BRCA2 mutation carriers with and without a diagnosis of ovarian cancer.

SETTING:

Genetic clinics.

PATIENT(S):

Detailed information regarding treatment of infertility was collected from a routinely administered questionnaire.

INTERVENTION(S):

None.

MAIN OUTCOME MEASURE(S):

Conditional logistic regression was used to estimate odds ratios and 95% confidence intervals associated with fertility treatment.

RESULT(S):

There was no significant relationship between the use of any fertility medication or IVF treatment (odds ratio, 0.66; 95% confidence interval 0.18-2.33) and the subsequent risk of ovarian cancer.
