Introduction:
Thymomas and thymic carcinomas are rare anterior mediastinal tumours, accounting for 0.2-1.5% of all cancers. Surgical resection is key to treatment, though invasion of surrounding structures like great vessels can complicate this. This case report details the management of a type B3 thymoma (T4 N0 M0) in a 41-year-old male.
Case Report:
A 41-year-old male presented with myasthenic symptoms and was diagnosed with a large thymic mass involving the brachiocephalic vein and superior vena cava. After 4 cycles of neoadjuvant chemotherapy, partial resection was performed, followed by radiotherapy. Residual disease led to a second surgery, during which tumour resection and vascular reconstruction using cardiopulmonary bypass were successfully completed. Postoperative recovery was uneventful.
Discussion:
Complete resection, including re-resection, when necessary, is crucial for improved outcomes in thymoma patients. Even with great vessel invasion, aggressive surgery, coupled with chemotherapy and vascular reconstruction, can achieve good survival outcomes.
Conclusion:
Multimodal management, including chemotherapy, complete resection, and vascular reconstruction, offers the best prognosis for invasive thymomas, even with great vessel involvement.
