Tiroid Papiller Mikrokarsinomunda Prognostik Faktörler

Abstract

Aim: Our aim in this retrospective study is to evaluate the factors that are important in the prognosis of thyroid papillary microcarcinoma. Material and Method: This study is a retrospective study. In the study, 277 thyroid papillary microcarcinoma nodules belonging to 178 patients, diagnosed in Kütahya University of Health Sciences Hospital, between 2010 and 2020, were included. The prognostic significance of tumor diameter, unilaterality, bilaterality, multifocality, number of tumor foci, fibrosis, distance from the capsule and Gal-3, HBME-1 and CK19 staining were investigated retrospectively by comparing with negative prognostic factors such as lymphovascular invasion, lymph node metastasis, capsular invasion and extrathyroidal spread. Moreover, the relationship between immunostains and fibrosis was examined. Results: The significant association was found between >0.5 tumor diameter and lymph node metastasis. Unilaterality, bilaterality, multifocality and number of tumor foci was associated with lymphovascular invasion and lymph node metastasis. Fibrosis was associated with capsular invasion and extrathyroidal spread. A correlation was found between the prevalence of Gal- 3 and capsular invasion and extrathyroidal spread, and between the prevalence of CK-19 and lymph node metastasis. A positive correlation was found between fibrosis and Gal-3 and CK19, and negative correlations with HBME-1 intensity. Conclusion: Negative prognostic markers are >0.5 tumor diameter, unilaterality, bilaterality, multifocality, number of tumor foci, fibrosis, Gal-3 and CK19 prevalence. A positive correlation was found between fibrosis and Gal-3 and CK19, and negative correlation with HBME-1 intensity.
