Demographic and Prognostic Significance of Surgically-Treated Intrathyroidal Thymic Carcinoma: A Systematic Review and Meta-Analysis.

Analysis of 55 articles (154 patients) showed that patients with intrathyroidal thymic carcinoma are likely to be symptomatic (95.2%, 95% CI 91.1-99.2) with neck mass (72.2%, 62.2-82.1) as the most common symptom with no laterality preferences (left:right, 46.4%:53.6%).

Overall survival (OS) at 15 years was 96.0% (mean OS time:19.7 years; median OS time 18 years).
