Thymoma Profile at Dr. Moewardi General Hospital: Does Thymoma Size Really Affect Distant Metastasis?

Abstract

Introduction: Size is a predictor factor of a patient’s prognosis and metastasis in solid tumors. This study determined the relationship between thymoma size and distant metastasis. Methods: A cohort retrospective study using medical record data was conducted at Dr. Moewardi General Hospital, Surakarta, from January 2019 to August 2021. Of 1,430 thoracic oncology patients, 150 (10%) had mediastinal mass with thymoma as the majority (48.6%). About 73 thymoma patients were included. The size of the thymoma was the dependent variable, and the metastasis (distant and non-distant) was the independent variable. The cut-off point of thymoma size was determined with receiver operating characteristic (ROC) analysis. The correlation of thymoma size with distant metastasis was analyzed with the Chi-Square test, and p 8.25 cm was categorized as large thymoma. Distant metastasis was found in 86.0% of large thymoma patients. The large tumors tend to spread into various sites (OR = 5.39; 95% CI 2.8-32.6; p = 0.002). Conclusion: Thymoma must be taken into account when there are male patients in their forties presented with dyspnea and mediastinal mass. The cut-off point of 8.25 cm for the thymoma size can predict distant metastasis.
