Regression in local recurrence in the contralateral breast following mastectomy in bilateral locally advanced breast cancer: A comparison of neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios

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.

The Research Progress on the Prognostic Value of the Common Hematological Parameters in Peripheral Venous Blood in Breast Cancer

Breast carcinoma is one of the most malignant tumors, severely influencing the physical and mental health of people. The latest epidemiological and clinical studies have found that breast tumor and inflammation are determinate relationships with each other. Inflammation is an essential component of the tumor microenvironment, and the change of inflammatory cells might influence tumor progression, such as neoplastic cell proliferation, migration, invasion, the collapse of antitumor immunity, metastasis and so forth. Peripheral blood tests at the time of diagnosis and treatment can reflect inflammatory conditions within the neoplasm. Evaluation of peripheral blood parameters including white blood cell, neutrophil, lymphocyte, monocyte, platelet counts, as well as neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocyte ratio (d-NLR) (neutrophil count divided by the result of white blood cell count minus neutrophil count), platelet-to-lymphocyte ratio (PLR) and lymphocyte-to-monocyte ratio (LMR), which are indicators of systematic inflammatory response, have been widely proposed as prognostic factors for many malignancies. To intensively study the relationship between the common markers in peripheral blood and the treatment or prognosis of breast cancer will have critical clinical significance and application prospect, and can provide useful information for the clinicians. Herein, we review the research progress in the prognostic role of the peripheral blood in breast cancer to provide a new method for the treatment and prognosis of breast cancer.
