Calcitonin assessment in thyroid diseases is recommended when medullary thyroid cancer (MTC) is suspected in fine needle biopsy, as well as in ‘suspicious for a follicular neoplasm’ class, especially oxyphilic type, in patients with germinal RET proto-oncogene mutation and in nondiagnostic biopsy when no surgical treatment is planned. This assessment is also suggested before any planned thyroid surgery to exclude MTC. Beyond diagnosis confirmation it is also suggeste...

Calcitonin and carcinoembryonal antigen are biochemical markers of medullary thyroid carcinoma (MTC). Assessment of the dynamics of their serum concentration allow for calculation of their doubling times that are independent risk factors for overall survival and progression-free survival in MTC. It is generally accepted that the dynamics and the doubling times remain stable during follow-up.Aim: The aim of the study was to retrospectively verify the stab...

Introduction: Reoperation due to recurrent or persistent thyroid cancer (TC) poses a real challenge to a surgeon who must properly estimate the benefit risk-ratio. Radioguided occult lesion localization (ROLL) technique may facilitate the localization and sufficient and safe removal of nonpalpable TC relapse.Aim: To analyze the efficacy of the ROLL technique in reoperation of TC relapse.Material and methods: A retrospective study o...

The routine use of adjuvant RAI treatment in low-risk DTC remains controversial due to the lack of unequivocal evidences of its effectiveness in radically operated subjects. The aim of the study was a retrospective evaluation of long-term outcomes of combined DTC treatment to evaluate the impact of adjuvant RAI therapy in the low risk group. Primary hypothesis was: ‘if adjuvant RAI treatment was unnecessary, a delay in RAI administration would have no impact on long-term ...

Introduction: Reliable prognostic factors are crucial to choose the optimal treatment strategy and follow-up for differentiated thyroid carcinomas (DTC) patients. Thus, the aim of the study was a retrospective evaluation of prognostic factors of cancer relapse in patients treated in a single institution.Material: The study group consisted of 510 DTC patients, staged pT1b-T4N0-N1M0, treated with total thyroidectomy followed by complementary 131...

Introduction: Gain of function mutations of RET protooncogene are associated with hereditary medullary thyrpoid cancer. There are mainly specific hot-spot RET gene mutations however they may differ between population.Aim of the study: In this study we report the prevalence of RET mutations in Polish population based on 20 years of experience of referral polish centers.Material and methods: RET ge...
