CLIFFORD HUDIS, MD: The goal of adjuvant therapy is to kill cancer cells that might have spread beyond the breast and lymph nodes before the surgery took place. So they exist; they're out and about in the body. And we don't have a way of identifying exactly where they are so we have to treat with medicines that circulate throughout the body and kill cancer cells wherever they may be.
ANNOUNCER: One of these "systemic" treatments is chemotherapy. Chemotherapy is easier to take than in years past. But nausea and diarrhea and other sometimes difficult side effects do occur. How does a patient weigh reduced risk of recurrence against the cost of these side effects?
GENEROSA GRANA, MD: There have been some interesting studies that show that women are very willing to accept the side effects of chemotherapy for even small amounts of gain. In one old study now, there was a suggestion that women, for as little as a 1 percent improvement in odds of survival, would willingly accept chemotherapy.
ANNOUNCER: For women with certain types of cancer, hormonal therapy is another treatment used to ward off recurrence. Before menopause, tamoxifen is the appropriate drug. After menopause, women can choose either tamoxifen or drugs called aromatase inhibitors. Hormonal agents are generally easier to handle than chemotherapy. But here, too, patients must balance risk and treatment goals.
GENEROSA GRANA, MD: The most bothersome side effects, for women, associated with hormonal therapy tend to be the hot flashes and the night sweats that are associated with both tamoxifen and the aromatase inhibitors.
ANNOUNCER: Sometimes because of family or medical history, treatment goals may include minimizing risk of blood clots or uterine cancer. Then the risks-and-benefits balance tips toward one type of these hormonal agents, or the other.
GENEROSA GRANA, MD: On a more serious vein, uterine cancer appears to be increased with tamoxifen, as do blood clots, clots in the leg, clots in the lung and even stroke.
The aromatase inhibitors don't appear to have such an increase in those side effects. They, on the other hand, are associated with worsening osteoporosis and fracture risk.
ANNOUNCER: Treatment of early stage breast cancer involves surgery, powerful chemotherapy, and hormonal medicines taken for many years. Women may find it easiest to chart a course through these treatments if they maintain a clear focus on therapeutic goals and balance side effects with their quality of life.
