Neoadjuvant Chemotherapy Combined with Breast-Conserving Surgery in the Treatment of Triple-Negative Breast Cancer

OBJECTIVE: To study the clinical efficacy and quality of life of neoadjuvant chemotherapy combined with breast-conserving surgery in the treatment of triple-negative breast cancer. METHODS: A retrospective analysis of 100 patients with triple-negative breast cancer was performed from May 2012 to April 2017. The patients were divided into an observation group and a control group according to different treatment methods, with 50 cases in each group. The control group received AC-T sequential chemotherapy after breast-conserving surgery, and the observation group received AC-T sequential chemotherapy before breast-conserving surgery (neoadjuvant). The operation time, postoperative immune function, postoperative tumor markers, postoperative efficacy, and postoperative complications of the two groups of patients were statistically analyzed, and the quality of life of the two groups of patients 1 year after the operation was compared. RESULTS: Compared with the control group, the operation time and blood loss of the observation group were significantly reduced, and the difference was statistically significant (P < 0.05). The observation group produced significantly higher total effective rate after treatment (82.00% vs. 56.00%) (P < 0.05). The observation group exhibited superior immune function indexes CD3, CD4, and CD8 after operation when compared with the control group (P < 0.05). There was no significant difference in serum tumor marker levels between the two groups before surgery and after surgery (both P > 0.05). Three days after operation, the levels of procalcitonin (PCT) and TNF-α in the observation group were lower than those in the control group (P < 0.05). There was no significant difference in the local recurrence rate, distant metastasis rate, and 3-year survival rate between the two groups (P > 0.05); however, the postoperative complication rate of the observation group was 6.00%, which was significantly lower than that of the control group (30%) (P < 0.05). The overall health, physiological function, physiological function, and body pain of the observation group were significantly higher than those of the control group (P < 0.05). CONCLUSION: Neoadjuvant chemotherapy combined with breast-conserving surgery for triple-negative breast cancer can not only improve the therapeutic effect of patients and reduce the incidence of postoperative adverse reactions but also significantly improve the quality of life of patients after surgery.
