Summary
Phrenic nerve (PN) sparing during thymoma resection is feasible, offering comparable survival rates to PN removal in high-risk patients. However, this approach is associated with an increased risk of recurrence, even with adjuvant radiation therapy.
Area of Science:
- Thoracic Surgery
- Surgical Oncology
- Neurosurgery
Background:
- Locally advanced thymomas frequently involve the phrenic nerve (PN) due to their mediastinal location.
- En bloc resection of the phrenic nerve can lead to severe postoperative complications, particularly in myasthenia gravis patients.
Purpose of the Study:
- To evaluate the feasibility and outcomes of sparing the phrenic nerve (PN) during thymoma resection.
- To compare the results of phrenic nerve sparing with en bloc resection in patients with locally advanced thymoma.
Main Methods:
- Retrospective study of 114 patients with Masaoka Stage III and IV thymomas involving the phrenic nerve (PN) between 1998 and 2012.
- Phrenic nerve (PN) was spared unless specific criteria for resection were met (e.g., preoperative paralysis, severe comorbidities).
- All patients received postoperative radiation therapy.
Main Results:
- Phrenic nerve (PN) was spared in 64% of patients and removed in 36%.
- Postoperative phrenic nerve (PN) palsy occurred in 5.4% of patients where the nerve was spared.
- Recurrence rates were higher in the spared group (39.5% vs. 19.5%), but 5-year disease-free and overall survival rates were comparable between groups.
Conclusions:
- Sparing the phrenic nerve (PN) during thymoma resection provides comparable long-term and disease-free survival to en bloc resection in high-risk patients.
- Phrenic nerve (PN) sparing is associated with a higher risk of recurrence, necessitating careful consideration despite adjuvant radiation therapy.
