Breast Conserving
Treatment an Option for Women with Implants
Behind the Cancer Headlines®
Breast conserving surgery followed by radiation therapy is a
good option for women with early-stage breast cancer who have breast implants,
according to a study presented at the American Society for Therapeutic
Radiology and Oncology's 47th Annual Meeting in
The new findings challenge past studies that showed delivering radiation to a breast with an implant in place causes significant problems in the implant, resulting in poor cosmetic results.
"Past research was based on a small sample of patients and older radiation techniques," said Rosalyn Morrell, M.D., lead author of this Mayo Clinic study. "Therefore, we investigated a larger group of women treated with radiation using newer techniques that refuted the reports of poor cosmetic outcome among patients."
Most women with early-stage breast cancer are able to undergo breast conservation surgery to keep their breast after treatment. Typically, this means that they first have surgery to remove the cancer (a lumpectomy), followed by a course of radiation therapy to kill any cancer cells that may remain. This approach is just as effective as a mastectomy in treating the cancer and is preferred by many women.
More women today are opting to have cosmetic breast implants. As women age, their risk of breast cancer increases, so a fraction of these women will eventually develop breast cancer. These are the patients who would be most interested in preserving their breasts and avoiding mastectomy.
Between 1994 and 2004, researchers reviewed the records of
26 breast cancer patients with previously augmented breasts who were treated
with breast conservation surgery and radiation at the Mayo Clinic. All patients
had their implants in place before their breast cancer diagnosis. Eighty-five
percent of patients followed over a three-year period had favorable cosmetic
results following radiation therapy. None of the patients in the study suffered
a relapse of their cancer.
