Summary

This study reports a rare case of a patient with myasthenia gravis and a mediastinal tumor. Multimodal treatment involving surgery, chemotherapy, and radiotherapy led to a favorable long-term outcome without recurrence.

Area of Science:

  • Oncology
  • Thoracic Surgery
  • Neurology

Background:

  • Myasthenia gravis can be associated with thymic tumors.
  • Mediastinal invasive tumors pose surgical challenges due to potential invasion of surrounding structures.

Observation:

  • A 61-year-old male patient presented with myasthenia gravis and a mediastinal invasive tumor.
  • Surgical resection revealed invasion into the pericardium, pleura, and diaphragm, necessitating an extended thymo-thymectomy and partial resection of adjacent organs.
  • Incomplete tumor resection was achieved due to diaphragmatic dissemination.

Findings:

  • The patient received adjuvant chemotherapy with ADOC (Adriamycin, Cisplatin, Cyclophosphamide, Etoposide) and radiotherapy to the mediastinum and diaphragm.
  • Four years post-treatment, the patient showed no evidence of tumor recurrence or myasthenia gravis exacerbation.

Implications:

  • This case highlights the effectiveness of a multimodal treatment approach for invasive mediastinal tumors with associated myasthenia gravis.
  • Aggressive surgical management combined with adjuvant chemotherapy and radiotherapy can achieve long-term disease control.
  • Further research into optimal treatment strategies for similar complex cases is warranted.
