RESUMEN

Breast cancer (BC) is mainly treated by surgery combined with chemotherapy, radiotherapy, and drugs comprehensively in clinical practice, and such a combined treatment can improve the survival rate of patients. This study was designed to determine the effect of modified radical mastectomy (MRM) combined with neo-adjuvant chemotherapy on patients with BC. Clinical data of 80 patients with BC were analyzed retrospectively. The patients were assigned to the control group (n=39) treated with MRM or the therapy group (n=41) treated with additional neo-adjuvant chemotherapy based on MRM. In this study, patients treated with MRM combined with neo-adjuvant chemotherapy experienced significantly shorter operation time and hospitalization time, less bleeding volume, and higher effective treatment rate than the control group. Moreover, the therapy group showed a significantly lower incidence of complications and higher life quality than the control group. Cox regression analysis showed that neo-adjuvant chemotherapy was an independent factor affecting the progression-free survival time of patients. This study has revealed the application value of MRM combined with neo-adjuvant chemotherapy in patients with BC.
