  <dc:description xmlns:ns0="xml" ns0:lang="en">Purpose: The sensitivity of cytology after fine needle aspiration (FNA-cytology) in detecting medullary thyroid carcinoma (MTC) is low.  To overcome this problem, measuring calcitonin (CT) in washout fluid of FNA (FNA-CT) has been largely diffused and showed good  performance. However, no evidence-based study exists comparing systematically the sensitivity of FNA-cytology and FNA-CT. This  study aimed to systematically review the literature and collect data allowing a head-tohead comparison meta-analysis between FNA- cytology and FNA-CT in detecting MTC lesions. Methods: The online databases of PubMed/MEDLINE and Scopus were searched  until June 2021. Original articles reporting the use of both FNA-cytology and FNA-CT in the same series of histologically proven MTC  lesions were included They were extracted general features of each study, number of MTC lesions (nodule and neck lymph nodes),  and true positive and false negatives of both FNA-cytology and FNA-CT. Results: Six studies were included. The sensitivity of FNA- cytology varied from 20% to 86% with a pooled value of 54% (95% CI 35–73%) and significant heterogeneity. The sensitivity of FNA- CT was higher than 95% in almost all studies with a pooled value of 98% (95% CI 96–100%) without heterogeneity. The sensitivity of  FNA-CT was significantly higher than that of FNA-cytology. Conclusions: FNA-CT is significantly more sensitive than FNA-cytology in  detecting MTC. Accordingly, FNA-CT represents the standard method to use in patients with suspicious MTC lesions, combined with cytology.</dc:description>
