Multidisciplinary treated thymomas with fatal outcome. A retrospective study

Area of Science:

• Thoracic Surgery
• Oncology
• Neurology

Background:

• Thymoma is a rare tumor of the thymus gland.
• Myasthenia gravis (MG) is frequently associated with thymoma.
• Outcomes for patients with thymoma and MG require further investigation.

Purpose of the Study:

• To identify factors contributing to fatal outcomes in patients who underwent surgery for thymoma.
• To analyze the impact of associated myasthenia gravis on mortality.
• To evaluate prognostic indicators in thymoma management.

Main Methods:

• Retrospective observational study of 10 thymoma patients.
• Analysis of patient data including associated conditions, tumor classification, and surgical outcomes.
• Long-term follow-up to determine causes of death.

Main Results:

• Mortality rate was 38.4% with a mean survival of 4.45 years.
• Myasthenia gravis (MG) exacerbation caused death in 60% of cases.
• Complete surgical resection was achieved in most patients; completeness of resection was a key prognostic factor.

Conclusions:

• Aggravation of myasthenia gravis (MG) is the primary cause of death, even after complete resection and treatment.
• Complete surgical resection is the most significant prognostic factor for thymoma patients.
• WHO types B and C thymomas were associated with fatal outcomes in this series.
