Committee Opinion No. 634: Hereditary Cancer Syndromes & Risk Assessment



open access 


ABSTRACT:

A hereditary cancer syndrome is a genetic predisposition to certain types of cancer, often with onset at an early age, caused by inherited mutations in one or more genes. Cases of cancer commonly encountered by obstetrician–gynecologists or other obstetric–gynecologic providers––such as breast cancer, ovarian cancer, and endometrial cancer––are features of specific hereditary cancer syndromes. The most common hereditary cancer syndromes related to gynecologic cancer include hereditary breast and ovarian cancer syndrome, Lynch syndrome, Li–Fraumeni syndrome, Cowden syndrome, and Peutz–Jeghers syndrome. A hereditary cancer risk assessment is the key to identifying patients and families who may be at increased risk of developing certain types of cancer. Screening should include, at minimum, a personal cancer history and a first- and second-degree relative cancer history that includes a description of the type of primary cancer, the age of onset, and the lineage (paternal versus maternal) of the family member. In addition, a patient’s ethnic background can influence her genetic risk. If a hereditary cancer risk assessment suggests an increased risk of a hereditary cancer syndrome, referral to a specialist in cancer genetics or a health care provider with expertise in genetics is recommended for expanded gathering of family history information, risk assessment, education, and counseling, which may lead to genetic testing.
