Breast cancer is being diagnosed earlier with about 94% of patients presenting with disease limited to the breast or axilla. Despite this trend, more and more patients are receiving adjunctive therapy. In Stage II disease the results of clinical trials suggest that single agent chemotherapy has little if any role in adjuvant therapy. Polychemotherapy can improve survival in premenopausal women with a gain in outcome of about 26%. The duration of therapy appears optimal when given for 6 months. In postmenopausal estrogen receptor‐negative women, chemotherapy also has a major role. Tamoxifen appears to offer approximately a 22% improvement in mortality for postmenopausal women. The longer duration of tamoxifen as adjuvant therapy appears to enhance the effect. Premenopausal women may also benefit using tamoxifen but the gain is less clear. Adding tamoxifen to chemotherapy does not enhance the effect. Patients with more than four positive lymph nodes may require more intensive therapy to show a major benefit. Radiotherapy can be integrated along with chemotherapy as adjunctive therapy.
