The Association With Recurrence in Breast Cancer Patients According to the Preoperative Blood Composition Ratio and Postoperative Pathological Results

ABSTRACT

Purpose@#This study aimed to determine the correlation between various clinical results, including recurrence in patients with breast cancer, and preoperative blood composition ratio and postoperative pathological results. @*Methods@#A total of 444 patients who underwent surgery were included, and the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and postoperative pathological results were classified into postoperative cancer stages to confirm the association with various clinical results, including recurrence. @*Results@#The median age of the patients was 51 years. The stages were divided into 1, 2, 3, and 4. Additionally, stages 1 and 2 comprised one group and stages 3 and 4 comprised another group. The cut-off values of the NLR, PLR, and MLR were confirmed to be 1.43, 158.84, and 0.21, respectively. It was noted that the association with recurrence was higher in the group with hormone receptor negative (p<0.001), higher stage (p<0.001), and underwent neoadjuvant chemotherapy (p<0.001). In the association with blood composition ratio and recurrence, survival was high in the PLR group with a high cut-off value (p=0.004). There was no significant relationship in the NLR and MLR groups. In the disease-free survival and overall-survival curves, only the PLR group showed a significant association of 0.003 and 0.001, respectively. The NLR and MLR groups did not show any significant result. @*Conclusion@#No significant association with recurrence and mortality was confirmed in the NLR and MLR groups. However, the preoperative blood test in the high PLR group showed recurrence and mortality rate were high.
