Deep Myometrial Infiltration leads to a measurable Inflammatory Response in Endometrial Cancer. A Prospective Observational Study.

Backgrounds: This study aims to evaluate the correlation between inflammation indices, such as neutrophil-lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MLR), platelet-lymphocyte ratio (PLR) and deep myometrial infiltration (≥50%) prospectively in patients with endometrial carcinoma, providing insights into the interaction between these parameters MATERIAL AND METHODS: A prospective observational cohort study was conducted at AOU Vanvitelli in Naples, Italy, from August 2023 to March 2024. Data from 161 patients undergoing surgery for endometrial cancer, including preoperative blood counts and histopathological information, were collected. Statistical analyses were performed using R software.
Results: After logistic regression, NLR and MLR showed a statistically significant association with deep myometrial infiltration (NLR log(OR) 0.15, P = .040; MLR log(OR) 0.30, P = .008). However, after multivariate logistic regression which included other risk factors such as grading, histotype, and MSI only NLR retained statistical significance, (Log(Or) 0.18, P = .031).
Conclusion: Our results demonstrate noticeable changes in inflammation indices associated with deep myometrial infiltration in endometrial carcinoma. Moreover, a correlation between NLR and deep myometrial infiltration exists regardless of microsatellite instability, histotype, and grading.
