Dear nburl, According to the 2000 National Institute of Health Consensus Conference on Adjuvant Therapy for Breast Cancer. Adjuvant chemotherapy (treatment given after surgery to try to prevent or minimize the growth of microscopic deposits of tumor cells that might grow into a recurrent tumor) is recommended for the majority of women with primary breast cancers that are greater than 1 cm in diameter. This is independent of nodal, menopausal or hormone receptor status.
An anthracycline containing regimen (the A – adriamycin – in AC) has been shown to produce a small but statistically significant improvement in survival over nonanthracycline- containing regimens. Prior to giving the adriamycin your heart function will be tested and usually again after the treatment course is completed to monitor. There is a point of total lifetime dose of adriamycin, where giving treatment after that amount the risk to the heart increases dramatically.
Adjuvant hormonal therapy is recommended to women whose tumors express hormone receptor protein (ER/PR+). At present five years of tamoxifen is standard adjuvant hormone therapy.
The above information is from the National Health Institute Consensus Statement regarding adjuvant treatment for breast cancer, published December 2000.
