My expertise is in the following area:
Etiology And Genetics Of Breast Cancer - A major emphasis of my research in recent years has been breast cancer. Working with Dr. Kathleen Malone, we have completed interviews on 1,400 women who were diagnosed with breast cancer before age 45 during the years 1983-1992 and a similar number of general population controls. A primary interest in these studies was the role of oral contraceptive use and induced abortion in the etiology of these tumors. Currently, we are funded to follow-up this cohort of women to determine their survival and relate it to tumor markers as well as patient characteristics and exposures. This cohort, as well as their control group, also are the focus of family studies looking at the genetics of breast cancer. We are also using DNA samples collected from these women and their controls to assess the role that the BRCA1, BRCA2 and AT genes play in this disease and to identify other genes. These studies are done in collaboraton with Drs. Peggy Porter, Elaine Ostrander, and Lue Ping Zhao.
We are also participating in a seven-year multicenter case-control study of breast cancer in women 35-64 years of age. The FHCRC study site is the genetics coordinating center for this study. This study,which includes 5,500 breast cancer cases and 5,500 controls, has as its primary goal to evaluate the risk of breast cancer associated with use of both oral contraceptives and hormone replacement therapy. Although previous studies have shown only modest increases in risk, if any, associated with oral contraceptive use, the risk associated use of both oral contraceptives and hormone replacement therapy can only now be evaluated. This study also has the goal to contrast risk factors for breast cancer in African Americans and Caucasians. One third of the study population is African American.
A second major interest we have had is evaluating the role of human papilloma viruses (HPVs) in the etiology of anogenital cancers; i.e., cervix, vulva, vagina, anal and penile. Although we now know the infection with HPV is necessary for the developmentof these tumors, since infection with HPV is relatively common, other exposures or patient characteristics are necessary for cancer to occur. One co-factor we have identified is being a cigarette smoker at diagnosis. We are exploring this association by looking for genetic susceptibility markers among our cases, particularly those that may be involved in the metabolism and detoxification of the active metabolities of the carcinogenics in tobacco. The gluathione S-transferases and debrisoquine hydroxylasegenes are currently being studied. These studies are done in collaboration with Drs. Steve Schwartz, Chu Chen, Denise Galloway, and James McDougall. Studies of thyroid cancer, prostate cancer, ovarian cysts and neoplasms, ovarian cancer, and uterine leiomyomas are also research topics that I
collaborate on with other faculty members in our group.
