Leptin as a predictive marker for lymph node metastasis in patients with papillary thyroid cancer

Authors

Abstract

Background
Leptin is a neuroendocrine hormone produced from adipose tissue with many vital functions. There is a well-known association between leptin and papillary thyroid cancer (PTC). Preoperative prediction of lymph node metastasis is one of the interesting topics in PTC. This study aimed to determine whether the serum leptin peptide is a significant predictor marker for node metastasis in cases with PTC.
Patients and methods
This is a prospective comparative study which was conducted at Ain Shams University Hospitals and El-Sheikh Zayed specialized hospital between January 2021 and January 2023. Forty patients with PTC were enrolled in this study and according to postoperative histopathology, we divided them into two groups: group A, 24 cases, those with pathological negative node and group B, 16 cases, those with pathological positive node.
Results
We had no statistically significant difference in the preoperative demographics data between both groups. Postoperatively, the median serum leptin level and percentage of leptin decrease were significantly higher in in group B. Multivariate logistic regression analysis showed that preoperative serum leptin level, thyroid imaging reporting and data system, multifocality, extra thyroid extension, and size of dominant nodule were significant predictors for node metastasis. There was a significant negative correlation between leptin level and age, while there was a significant positive correlation between leptin level and lymph node metastasis.
Conclusion
Preoperative serum leptin level is considered a significant predictor marker for lymph node metastasis in PTC.
