SAN FRANCISCO – Dr. Eleftherios (Terry) Mamounas reviews the first day of the annual breast cancer symposium sponsored by the American Society of Clinical Oncology.

Key sessions covered the increasingly complex topic of genetic risk assessment and stirred up the debate about management of ductal carcinoma in situ (DCIS). Dr. Mamounas, professor of surgery at the University of Central Florida and medical director of the comprehensive breast program at the University of Florida Health Cancer Center, both in Orlando, discusses the significance of atypical hyperplasia, including new data suggesting that the fourfold increased risk of developing breast cancer in women with ductal carcinoma in situ (DCIS) is not further worsened by having a family history of DCIS.

Among the top oral presentations, one study suggested that a nomogram helped predict the risk of locoregional recurrence in patients treated for breast cancer using accelerated partial-breast irradiation. Another study examined the effect of hormone receptor status and local treatment on overall survival for patients with early-stage breast cancer.

Dr. Mamounas also discusses his own study, which he presented at the meeting, showing lower rates of locoregional recurrence in patients who have a pathologic complete response to neoadjuvant therapy. He puts the findings in context with tips on how to incorporate pathologic complete response data into clinical practice.

A separate study reported some of the first data on complication rates after unilateral or bilateral mastectomy and reconstruction. Dr. Mamounas wraps up the day’s review by discussing sessions on the effect of luteinizing hormone-releasing hormone agonists during chemotherapy in preserving ovarian function, and on breast cancer prevention, including the use of aromatase inhibitors.

Dr. Rugo is director of the Breast Oncology Clinical Trials Program at the University of California, San Francisco, Helen Diller Family Comprehensive Cancer Center.

Dr. Mamounas reported financial associations with Genomic Health, Genentech/Roche, Pfizer, GlaxoSmithKline, Eisai, Celgene, and GE Healthcare.
