Expression and prognostic value of ratios of platelet lymphocyte, neutrophil lymphocyte and lymphocyte monocyte in breast cancer patients.

BACKGROUND

The ratios of systemic inflammatory cells, neutrophil lymphocyte (NLR), platelet lymphocyte (PLR) and lymphocyte monocyte (LMR) can be used as prognostic indicators of breast cancer (BC). The purpose of this study was to explore the value of inflammatory markers in predicting the pathological reaction and prognosis of patients with BC after surgical treatment.

METHODS

A total of 144 BC patients who received standard neoadjuvant therapy in Shangqiu First People's Hospital from January 2016 to January 2018 were analyzed retrospectively. The clinical data of patients were collected and the effects of NLR, PLR and LMR on disease-free survival were evaluated by chi-square test and COX regression. The diagnostic value of NLR, PLR and LMR in BC recurrence was analyzed by receiver operating characteristic (ROC) curve.

RESULTS

Of the 144 patients, 20 (13.89%) had local or distant metastasis. The areas under the ROC curve of NLR, PLR and LMR in peripheral blood for the diagnosis of BC recurrence were 0.713, 0.683 and 0.765, respectively. Multivariate Cox regression analysis showed that T stage, lymph node metastasis, PLR, LMR and HER2 were independent risk factors for prognosis.

CONCLUSION

Inflammatory markers based on NLR, PLR and LMR may become biological indicators to predict the pathological features and prognosis of invasive BC in the future.
