An Analysis of Effect Postoperative Adjuvant Therapy for Breast Cancer

Objective To study the effect of stage, Iymph nodes and therapy methods on the survival rate for breast cancer after radical operation. Methods Treatment results were compared between 110 stage Ⅱ and 90 stage Ⅲ breast cancers who received postoperative radiotherapy(RT),Chemotherapy (CT)and chemotherapy plus radiotherapy (CRT) in our department. Results The local recurrence rates for stage Ⅱ and stage Ⅲ with RT group and CRT group compared with CT group have significance (P＜0.05).Distance metastasis rates for stage Ⅲ patients with CT group and CRT group compared with CT group have significance (P＜0.05).The 5-year survival rates for patients with ≥4 positive axillary's Iymph nodes in stage Ⅱ decrease (P＜0.05),The 5-year survival rates of stage Ⅲ breast cancer declined gradually with increase of the N. Conclusion Postoperative RT of breast cancer could reduce the local recurrence rates.Postoperative CT for stage Ⅲ breast cancer could reduce distance metastasis rates.Axillary's Iymph nodes effect on the 5-year survival rates.
