Value of the NF-B signalling pathway and the DNA repair gene PARP1 in predicting distant metastasis after breast cancer surgery
SCIENTIFIC REPORTS(2024)
摘要
The DNA repair gene PARP1 and NF-kappa B signalling pathway affect the metastasis of breast cancer by influencing the drug resistance of cancer cells. Therefore, this study focused on the value of the DNA repair gene PARP1 and NF-kappa B pathway proteins in predicting the postoperative metastasis of breast cancer. A nested case-control study was performed. Immunohistochemical methods were used to detect the expression of these genes in patients. ROC curves were used to analyse the predictive effect of these factors on distant metastasis. The COX model was used to evaluate the effects of PARP1 and TNF-alpha on distant metastasis. The results showed that the expression levels of PARP1, IKK beta, p50, p65 and TNF-alpha were significantly increased in the metastasis group (P < 0.001). PARP1 was correlated with IKK beta, p50, p65 and TNF-alpha proteins (P < 0.001). There was a correlation between IKK beta, p50, p65 and TNF-alpha proteins (P < 0.001). ROC curve analysis showed that immunohistochemical scores for PARP1 of > 6, IKK beta of > 4, p65 of > 4, p50 of > 2, and TNF-alpha of > 4 had value in predicting distant metastasis (Se-PARP1 = 78.35%, Sp(PARP1) = 79.38%, AUC(PARP1) = 0.843; Se-p50 = 64.95%, Sp(p50) = 70.10%, AUC(p50) = 0.709; SeTNF-alpha = 60.82%, Sp(TNF-alpha) = 69.07%, AUC(TNF-alpha) = 0.6884). Cox regression analysis showed that high expression levels of PARP1 and TNF-alpha were a risk factor for distant metastasis after breast cancer surgery (RRPARP1 = 4.092, 95% CI 2.475-6.766, P < 0.001; RRTNF-alpha = 1.825, 95% CI 1.189-2.799, P = 0.006). Taken together, PARP1 > 6, p50 > 2, and TNF-alpha > 4 have a certain value in predicting breast cancer metastasis, and the predictive value is better when they are combined for diagnosis (Se-combine = 97.94%, Sp(combine) = 71.13%).
