Thoracoscopic thymectomy with partial superior vena cava resection for locally advanced thymomas

Area of Science:

• Thoracic Surgery
• Surgical Oncology
• Minimally Invasive Procedures

Background:

• Video-assisted thoracoscopic surgery (VATS) is increasingly used for early-stage thymic malignancies.
• VATS is not typically recommended for locally advanced thymic tumors.
• This study explores VATS thymectomy with partial superior vena cava (SVC) resection for advanced thymic tumors.

Purpose of the Study:

• To evaluate the feasibility and safety of VATS thymectomy with partial SVC resection for locally advanced thymic tumors (IASLC/ITMIG stage III).
• To assess peri-operative outcomes and short-term follow-up results of this challenging surgical approach.

Main Methods:

• Retrospective review of patients who underwent VATS thymectomy with partial SVC resection between August 2017 and October 2018.
• Analysis of peri-operative data including operative time, blood loss, chest tube duration, and hospital stay.
• Evaluation of short-term follow-up for complications and recurrence.

Main Results:

• Four patients with stage III thymic tumors invading the SVC underwent VATS thymectomy with partial SVC resection.
• Average operative time was 228 minutes, with a mean blood loss of 88 mL.
• Mean chest tube drainage was 4.5 days, and mean hospital stay was 7.3 days, with no major complications, mortality, or recurrence at 14 months follow-up.

Conclusions:

• VATS thymectomy with partial SVC resection is technically feasible for selected patients with locally invasive thymic tumors involving limited SVC invasion.
• Careful patient selection and significant surgical expertise are crucial for successful outcomes.
• This minimally invasive approach offers a potentially viable option for advanced thymic malignancies previously considered unresectable via VATS.
