Objective The study was aimed to further explore risk factors of axillary lymph node metastasis in Luminal A breast cancer and revealed high-risk clinicopathological features.Methods From January 2017 to December 2019, the clinical and pathological data of 237 Luminal A breast cancer patients diagnosed in our hospital were retrospectively analyzed. For the identification of related risk factors of axillary lymph node metastasis in Luminal A breast cancer, χ2 test for univariate analysis and logistic regression model for multivariate analysis were conducted.Results Among the 237 patients with Luminal A breast cancer, 115 patients were associated with lymph node metastasis (48.5%). The univariate analysis indicated that multifocal tumor (P=0.001), p53 mutation (P=0.012), and lymphovascular invasion (P=0.022) were correlated with axillary lymph node metastasis in the Luminal A breast cancer. The multivariate analysis identically showed that multifocal tumor (P=0.009), p53 mutation (P=0.019), and lymphovascular invasion (P=0.021) were independent risk factors of axillary lymph node metastasis.Conclusion Multifocal breast cancer, p53 mutation, and lymphovascular invasion are risk factors of axillary lymph node metastasis in Luminal A breast cancer.
