Comparison of unexpected vs preoperatively diagnosed thyroid carcinomas

Research output: Contribution to conferenceAbstractpeer-review

Abstract

Aim of study is to determine main diagnostic, management and outcome differences in thyroid cancer which were unexpected findings and those diagnosed prior operations. From 2015-2020 were performed 1475 thyroid operations. Thyroid cancer was diagnosed in 456 (30.9%) patients. From those unexpected cancers diagnosed in 110 (24.1%) patients – Group A, 346 (75.9%) were preoperatively diagnosed carcinomas – Group B. Data were analysed regarding indications for surgery, operation type, morphology, tumour size, thyroid weight. Main indications for surgery in Group A were compression symptoms –71 and thyrotoxicosis – 39 vs in Group B – suspected malignancy in 144, a proven malignancy – 196 cases. Fine needle aspiration (FNA) was performed in Group A in 57 (51.8%), B - 333 (96.2%) cases. Thyroidectomy performed in Group A: 65 (59.1%), B –297 (85.8%); unilateral procedure: Group A – 37 (33.6%), B – 46 (13.3%). Papillary cancers found in Group A – 83 (75.5%), B – 312 (90.2%); follicular cancers – Group A: 21 (19.1%), B - 20 (5.8%). Medullary cancer and anaplastic cancer found in Group A and B respectively: 2 (1.8%) and 2 (1.8%) vs 11 (3.2%) and 0 (0 %). Multiple different cancers Group A: 2 (1.8%), B - 3 (0.9%). Microcarcinomas found in Group A – 77 (70.0%), B – 162 (46.8%). Mean tumour size in Group A: 13.4mm (1–95 mm), B – 14.0mm (1–75mm). Multifocal cancers found in Group A: 21 (19.1%), B – 86 24.9%. Mean excised thyroid weight in Group A – 53.9g, B – 30.0g. Metastatic lymph nodes were diagnosed in 8 (7.2%) cases in Group A, B – 80 (23.1%). Unexpected thyroid cancer is not rare finding in patients operated due to benign pathologies. Large part of follicular cancers is still found incidentally despite commonly performed FNA.
