Abstract:
Objective:To investigate the changes of lymphocyte to monocyte ratio (LMR), matrix metalloproteinase-2 (MMP-2), hypoxia inducible factor-1 (HIF-1 α) in patients with breast cancer undergoing surgical resection before and after radiotherapy and their relationship with short-term prognosis.Methods:106 patients with breast cancer who underwent surgical resection and radiotherapy from Jan. 2021 to Jan. 2024 were analyzed as the study subjects. All patients received the same scheme of radiotherapy. The changes of LMR, MMP-2, and HIF-1 α levels at different time points before and after radiotherapy were recorded, and the clinical efficacy of the two groups of patients after radiotherapy was compared. According to the short-term efficacy after radiotherapy, the patients were divided into 31 patients with poor efficacy (progression+deterioration) and 75 patients with good efficacy (complete remission+effective remission+partial remission). The basic clinical data of the two groups were compared. The binary regression analysis was used to analyze the factors that affect the short-term prognosis of patients with breast cancer who had undergone surgery after radiotherapy. A risk prediction model was constructed, and the ROC analysis model was used to predict the value.Result:Compared with before radiotherapy, LMR decreased and MMP-2 and HIF-1 α increased after one week of radiotherapy ( t=2.68, -2.76, -1.96, P=0.008, 0.006, 0.052); After one course of radiotherapy and three courses of radiotherapy, LMR increased and MMP-2 and HIF-1 α decreased ( t=-3.02, 5.14, 5.86, all P<0.05; t=-7.95, 19.80, 21.36, all P<0.001). Low expression of LMR, high expression of MMP-2 and high expression of HIF-1 α are independent risk factors for poor short-term prognosis of breast cancer patients after radiotherapy. LMR、MMP-2、HIF-1α、The prediction model can predict the poor short-term prognosis of breast cancer patients after radiotherapy. The AUC values were 0.780 (95% CI: 0.674~0.887), 0.759 (95% CI: 0.659~0.859), 0.840 (95% CI: 0.748~0.931), and 0.887 (95% CI: 0.808~0.965), respectively. When taking the cut-off values, the sensitivities were 0.853, 0.903, 0.677, and 0.920, and the specificities were 0.677, 0.533, 0.933, and 0.774, respectively. Bootstrap method (B=1000) was used to perform internal validation on the prediction model of poor short-term prognosis of breast cancer patients after radiotherapy. The results showed that the prediction curve after deviation correction was close to the ideal state, and the C-index reached 0.774, indicating that the model had strong prediction ability. In addition, the decision curve of the model shows that the net profit is always positive and better than the two invalid reference lines within the threshold probability range of 0.1 to 1.0. Conclusion:LMR of postoperative radiotherapy patients with breast cancer decreased first and then increased, MMP-2 and HIF-1 α increased first and then decreased, all of which are independent predictors of short-term prognosis. The combined model has a significant predictive effect on poor efficacy and can be used as an important reference for clinical prognosis evaluation.
