F:ALTH Jewish Genetics Ashkenazi Jews should be aware of BRCA gene mutation. Dr. Bernard Lublin Special to the Jewish News he telephone call. Breast can- cer. My 33-year-old niece, Karen, who has three young daughters and no family history of breast cancer. Thirty-five years earlier, I had diagnosed her grandmother with ovarian cancer. Her own internist had not even considered this diag- nosis. His advice for treatment of her symptoms of abdominal bloat- ing: "Stop eating gassy foods:' We didn't know then that the grandmother's ovarian cancer was due to an inherited "BRCA' (short for breast cancer) mutation. We didn't know that the grandmother had silently passed this mutation to her son, that her son had then silently passed the inherited muta- tion to his daughter and that any BRCA mutation can cause both breast cancer and ovarian cancer. At one time, as part of a "com- plete" medical exam, Karen had told her physician of her grand- mother's ovarian cancer. The physi- cian erroneously advised that she need not worry "since this was on the paternal side of her family" In fact, BRCA mutations can be inher- ited from either the mother or the father with equal frequency and can be passed on to both a daugh- ter and a son. After the lump (found by self- exam), the worrisome mammo- gram and the diagnosis by needle biopsy, Karen consulted a surgeon. He erroneously told her that the appropriate surgery would be a lumpectomy, followed by radiation and chemotherapy. Fortunately, she consulted a sec- ond surgeon. His assessment: an Ashkenazi Jew, age 33, with a grandmother who died of ovarian cancer — a genetic test was need- ed to determine the appropriate surgery. T N October 27.2005 Testing's Value The resulting report, positive for a BRCA genetic mutation, led to a full understanding of Karen's disease. Presence of a BRCA mutation in Ashkenazi Jewish women confers a 60-87 percent lifetime risk of breast cancer versus the risk for the female population at large of 10-12 percent. After a thorough discussion of the cancer risks and risk reduction options, patient and surgeon decid- ed jointly for complete and bilateral mastectomy. The reasons: All breast tissue in a woman with an inherit- ed BRCA mutation has a propensi- ty to become cancerous. There is a significant incidence of a later sec- ond malignancy in the same breast when treated by lumpectomy or by simple mastectomy. And there is a significant risk of a later breast cancer in the opposite breast: 15 percent within five years, 27-42 percent within 10 years. This sec- ond malignancy is not a result of residual cells from the earlier can- cer; it is a new malignancy devel- oping in genetically compromised breast tissue. Karen would also have chemotherapy and a prophylactic oophorectomy (removal of ovaries). The same gene mutations that cause breast cancer also cause ovarian cancer. In fact, it was the same mutation that caused her grandmother's ovarian cancer. The lifetime risk of ovarian cancer in a woman with a BRCA mutation is 27-44 percent. Therefore, a woman with a BRCA mutation who has completed childbearing has good reason to consider prophylactic oophorectomy, which not only will reduce the risk of ovarian cancer by 96 percent, but also will reduce the risk of breast cancer by 50 per- cent. And now this surgery can be done on an outpatient basis by laparoscopy. The normal healthy BRCA genes Happy and healthy are Keith and Betsy Lublin of West Bloomfield; Karen and Jon Morton of Miami, with their daughters Eliza and Stephanie, 5, and Rachel, 9; Kathi Paul of Atlanta and father, Bernard Lublin of Richmond, Va. are considered tumor-suppressant genes. Every person has a pair of these genes — one set inherited from each parent. In most individ- uals, both sets are normal. However, an individual might inherit one with a mutation that causes it to not work properly. This is comparable to having a bicycle with two hand brakes — one of which does not work. If the indi- vidual then loses function of the other normal gene (through dam- age from pesticides, industrial chemicals, etc.) then all "braking" control of cell reproduction has been lost and cancerous cell repro- duction proceeds. Karen was diagnosed in 2001. She now lives cancer-free in Miami with her husband, Jon, and daugh- ters, Rachel, 9, and twins Eliza and Stephanie, 5. ❑ Dr. Bernard Lublin is a retired physi- cian. When his niece Karen devel- oped breast cancer, he became aware of the lack of knowledge of the BRCA gene mutation. He began work- ing to raise that awareness among the general and Jewish communities and to advocate for insurance cover- age for testing, reductions in the cost of testing and for changes in stan- dard protocols in working with Ashkenazi cancer patients. He wrote this story to spread the word, espe- cially during October, which is Breast Cancer Awareness Month. He lives in Richmond, Va., and Naples, Fla. His son Keith and daughter-in-law Betsy live in West Bloomfield and had their first child this week. Genetic Testing? •Ashkenazi Jews who have had breast cancer before the age of 50 or who have had ovarian cancer at any age. This serves to find out whether additional treatment is recom- mended, such as oophorectomy or mastectomy of the opposite breast. Testing also benefits offspring, sisters and brothers by informing them that each has a 50 percent chance of the same mutation and that they also should seriously consider testing and preventive measures. This applies to all now living after a diagnosis of breast or ovarian cancer. •Ashkenazi Jews with a family history of breast cancer below age 50 or ovarian cancer at any age. Studies have shown that the risk of breast or ovarian cancer is not related to the number of family members with these can- cers. •Also, women with a BRCA mutation should consider mammography beginning at age 25. Health Insurance Women may fear that testing positive (or even undergoing genetic testing) will lead to discrimination by health insurance carriers. Yet Michigan and most other states already have legislation forbidding discrimination by health insurance carriers based upon genetic information. This protection is reinforced by federal legislation known as HIPAA that was passed in 1996. In large measure, the desire for national anti-discrimi- nation legislation is symbolic rather than substantive. While this has become a rallying point for multiple con- stituencies, most states already have taken care of this issue. It is understood that carriers of life insurance and disability insurance may still discriminate. This results from legitimate actuarial concerns of "adverse selection." How to Proceed Genetic testing for Ashkenazi BRCA mutations is available at a cost of $415, though this is normally covered by health insurance. The test, a simple blood test, is available after a short session with a genetic counselor. Testing is available through the University of Michigan in Ann Arbor at (734) 764-0107 and through the Detroit-based Karmanos Cancer Institute at (313) 576-8748. Results are available within four weeks (although an expedited answer is available for an additional cost). 21
