Volumen plaquetario medio e índice de plaquetas-linfocitos como factores de pronóstico en cáncer papilar de tiroides.

Abstract

Background: Papillary thyroid cancer is the most common endocrine neoplasia. There are prognostic factors that establish risk of recurrence and mortality; however, patients considered low risk may have a less favorable evolution and hence the importance of finding new markers.

Objective: To assess whether the mean platelet volume (MPV) and the platelet-lymphocyte index (PLI) show a relationship with the clinical staging in papillary thyroid cancer.

Method: Retrospective, observational and analytical study. Preoperative MPV and PLI were recorded, its relationship with TNM and MACIS systems was sought, as well as locally advanced invasion and tumor focality.

Results: 107 cases treated from November 2017 to February 2020. No statistically significant difference was observed in these two preoperative parameters with advanced and initial stages, risk groups or tumor focality. The statistical analysis used was one-way ANOVA with SPSS 25, a 95% confidence interval and p < 0.05.

Conclusions: Despite the logical reasoning of tumor pathophysiology, our study did not find a relationship between papillary thyroid carcinoma with MPV and PLI, and should be complemented with more extensive studies.
