ABSTRACT

Background and Purpose:The recurrent rate of breast cancer after mastectomy was 5%~20%,high risk factors were included it could achieve 34%~40%,Chest wall recurrence was the most common.This paper explores the reason for chest wall recurrence of breast cancer after mastectomy,hoping to find an efficient way to prevent and reduce chest wall recurrence after mastectomy.Methods:For 39 patients with local recurrence on the chest wall after mastectomy clinical data was reviewed retrospectively.Results:This group of patients was 5.1% of all breast cancer patients in the same period.Most of recurrences(59.0%)occured within two years affer operation.The recurrent rate of T_1～T_4 was 1.6%、1.9%、9.7% and 37.2% respectively.Rate of chest wall recurrence in patients with negative axillary nodes and positive axillary nodes was 1.3%、7.6%,but if the amount of positive axillary nodes≥4,it was 13.4%.Conclusions:In the patients who had more positive axillary nodes,larger primary tumor and no proper adjuvant therapy,recurrence on the chest wall was seen more often.Adjuvant chemotherapy and postoperative radiotherapy are efficient ways to prevent recurrence on the chest wall.
