Summary
Introduction: Papillary thyroid cancer (PTC), especially micropapillary variant (MPTC), is the most common thyroid malignancy. Biological behavior is not aggressive and the patient’s prognosis is satisfactory. The objective of our comparative retrospective study was to evaluate whether the incidence is rising in the Region of Zlín and if less extensive approach was adopted by Czech endocrinologists.
Methods: We compared 2 groups from years 2005–2008 and 2014–2018. The incidence of thyroid cancer, the PTC and the MPTC, the extent of the surgery and the lymphadenectomy, number of removed lymph nodes and the number of positive lymph nodes were observed.
Results: We gathered 1353 patients in group 1. We found 220 malignancies (16.3%), 180 (81.8%) were PTC with MPTC variant in 44.4% (80 patients). All patients underwent a total thyroidectomy. We made 18 central and 10 lateral lymphadenectomies, 280 lymph nodes were collected with metastasis in 29,3 %. In group 2 with 1569 patients we found 318 (20.3%) carcinomas, PTC in 302 (94.6%) cases. The MPTC accounted for 215 (67.4%) cases. 10 patients with MPTC underwent hemithyroidectomy only. Numbers of central and lateral lymphadenectomies rose to 52 and 24 respectively. We gathered 376 lymph nodes with proven metastasis in 44.4% of these nodes.
Conclusion: Both, the incidence and the frequency of PTC and MPTC are rising in our region. However, the number of less invasive procedures is not increasing significantly despite representing a sufficient way of treatment. We need wider adoption of these evidence-based recommendations by indicating endocrinologists in the Czech Republic.
