Abstract
Introduction
Thymic epithelial tumors represent the most common cause of anterior mediastinal masses in adults. Among these tumors, thymomas constitute the majority, whereas thymic carcinomas are less prevalent and associated with a poorer prognosis. This study seeks to investigate the clinical and prognostic factors of these rare entities, thymoma, and thymic carcinomas.
Materials and methods
We conducted a retrospective analysis on a cohort of 60 patients diagnosed with thymoma and thymic carcinoma, who were under follow-up at our clinic between January 1998 and February 2023. The clinical characteristics and prognostic factors of these patients were analyzed separately.
Results
Thymomas accounted for 75% of the cases. The median age at diagnosis was 46 years in both patient groups. Masaoka stage 4 was observed in 28.9% of thymoma patients and 66.7% of thymic carcinoma patients. The median overall survival (mOS) for thymoma patients was 261.4 months, while it was 9.23 months for patients with thymic carcinoma. Curative surgery emerged as a prognostic factor significantly influencing overall survival in both thymoma and thymic carcinoma patients.
Conclusion
Our study highlights the significance of Eastern Cooperative Oncology Group (ECOG) performance status and curative surgery as prognostic factors affecting overall survival in thymoma patients. In thymic carcinoma, only curative surgery was found as a prognostic factor. These findings may enhance patient care and guide personalized treatment strategies. Further investigations and prospective studies are warranted to corroborate and expand upon these results.
