    P2.04-012 - A Risk of Death from a Second Cancer Following Complete Resection of Thymoma (ID 4217)

    14:30 - 14:30  |  Author(s): H. Date
    • Abstract

    Background:
    A portion of patients undergoing complete resection of thymoma develop recurrence of thymoma, while those undergoing thymectomy for thymoma are at risk of developing a second cancer, but it remains unknown whether those patients are more at risk of death from thymoma or from a second cancer.
    
    Methods:
    Retrospective chart review was performed on our prospectively maintained database of patients undergoing complete resection of thymoma at our institution between 1991 and 2016. Thymoma-specific survival was calculated from thymectomy to death of recurreence of thymoma. Second cancer-specific survival was calculated from thymectomy to death of a second cancer. Both were estimated with Kaplan-Meier method.
    
    Results:
    Follow-up ranged from 1 to 239 months (median: 54). One hundred and sixty-four patients were identified. During the follow-up, there were four thymoma deaths and 4 deaths from a second cancer. Five-year and 10-year thymoma specific survival was 97.8% and 96.1%, respectively. Five-year and 10-year second cancer specific survival was 98.2% and 96.1%, respectively.
    
    Conclusion:
    It appears that patients undergoing thymectomy for thymoma are at a similar risk of a second cancer death to that of thymoma death. However, there are too few events during the follow-up and a multi-institutional database is required to more rigorously evaluate both risks.
