Effects of modified radical mastectomy on immune function,thyroid hormone and prognosis of patients with breast cancer
Objective To investigate the effects of modified radical mastectomy on the immune function,thyroid hormone and prognosis of patients with breast cancer.Methods From May 2019 to May 2022,153 patients with breast cancer who were clinically studied and followed up in the Qionghai People's Hospital were selected in this study.They were divided into control group(n=65)and study group(n=88).Traditional and modified radical mastectomies were applied in the control group and study group,respectively.Perioperative related indicators,immune function and thyroid hormones before surgery and one month after surgery,complications and prognosis within one year after surgery were compared between the two groups.Results The study group had shorter operating time and hospitalization time and less intraoperative bleeding than the control group(P＜0.05).Compared to before surgery,CD4+ T,CD4+/CD8+,natural killer(NK)cells in both groups were significantly decreased one month after surgery(P＜0.05),while CD8+ T cells were significantly increased(P＜0.05).The CD4+ T,CD4+/CD8+ and NK cell levels in the study group were significantly lower than those in the control group(P＜0.05),while CD8+ T cell level in the study group was significantly higher than that in the control group(P＜0.05).Compared to before surgery,triiodothyronine(T3),thyroxine(T4),free triiodothyronine(FT3)and free thyroxine(FT4)in both groups were significantly decreased one month after surgery(P＜0.05),while thyroid stimulating hormone(TSH)was significantly increased(P＜0.05).The levels of T3,T4,FT3 and FT4 in the study group were significantly lower than those in the control group(P＜0.05),while TSH in the study group was significantly higher than that in the control group(P＜0.05).The study group had lower incidence of complications,local recurrence rate,axillary lymph node recurrence rate,and distant metastasis rate and higher survival rate than the control group(P＜0.05).Conclusion Modified radical mastectomy can effectively shorten the operation time and hospital stay,decrease intraoperative bleeding,improve the immune function and thyroid hormone levels,reduce complications,and improve the prognosis and survival of patients with breast cancer.
