Medullary thyroid cancer (MTC) is a rare neuroendocrine neoplasm with calcitonin as its main biomarker. Elevated neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII) have been considered as negative prognostic factors in other neoplasms. This study aims to evaluate the potential role of NLR, PLR, and SII as biomarkers in MTC.
Medullary thyroid cancer (MTC) is a rare neuroendocrine neoplasm, and calcitonin is its main biomarker. An elevated neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and systemic immune-inflammation index (SII) have been considered as negative prognostic factors in several neoplasms. The aim of this study is to evaluate the potential role of NLR, PLR and SII as biomarkers in MTC. Clinical data and tumor histological characteristics of patients with sporadic MTC, referred to the NET Unit of Federico II University of Naples (ENETS CoE) from 2012 to 2022, were retrospectively evaluated by analyzing preoperative and postoperative calcitonin, NLR, PLR and SII. We included 35 MTC patients undergoing total thyroidectomy. The mean preoperative NLR was 2.70 (& PLUSMN;1.41, 0.93-7.98), the PLR was 121.05 (& PLUSMN;41.9, 40.98-227.23) and SII was 597.92 (& PLUSMN;345.58, 186.59-1628). We identified a statistically significant difference between pre- and post-thyroidectomy NLR (p = 0.02), SII (p = 0.02) and calcitonin (p = 0.0) values. No association with prognosis or tumor characteristics emerged. Elevated preoperative NLR and SII suggest a possible disease-associated inflammatory response, and their reduction after surgery may be related to debulking effects. Further studies are needed to define the role of NLR, PLR and SII as prognostic markers in MTC.
