P3.16-039 - Right Upper Lobectomy with SVC Reconstruction after Induction Chemoradiotherapy for a Patient with Bulky N2 NSCLC (ID 7522)
09:30 - 09:30 | Author(s): T. Kawamura
- Abstract
Background:
The treatment strategy for N2 IIIA non-small cell lung cancer (NSCLC) is still controversial. Some believe that patients with bulky N2 are not good candidates for trimodality treatment. In addition, with regard to the survival of patients underwent lung resection with SVC reconstruction, patients with SVC involvement due to direct invasion of the main tumor have longer survival compared to those with SVC involvement due to mediastinal lymph node (LN) metastasis. We encountered a patient with bulky N2 NSCLC with SVC involvement.
Method:
A 69-year-old man complaining of cough was referred to our hospital for examination of a chest abnormal shadow. Chest CT showed a 58-mm pulmonary mass lesion in the right upper lobe and mediastinal LN swelling (#4R: 31 mm, #2R: 15 mm), which resulted in stenosis of the SVC. Transbronchial biopsy of the mass and EBUS-TBNA of the #4R LN showed squamous cell carcinoma. Since distant metastasis was not apparent, the patient was diagnosed with locally advanced IIIA lung cancer with bulky N2. After induction of concurrent chemoradiotherapy (2 cycles CDDP+VNR + 45 Gy radiotherapy), the lesion showed 9.5% reduction and was defined as stable disease according to the RECIST criteria.
Result:
Since it would be difficult to dissect the SVC and #4R LN, and this procedure would require substantial time, we approached by median sternotomy and right fourth intercostal thoracotomy and established the shunt between the left brachiocephalic vein and the right atrial appendage prior to cross-clump of the SVC. The SVC was resected because of extensive firm adhesion of the #4R LN, and reconstructed with a 12-mm reinforced polytetrafluoroethylene graft. The anastomosis was performed using a 5-0 Plorene suture. The patient underwent right upper lobectomy with mediastinal dissection and combined resection of the SVC. The operation time was 494 min and blood loss was 700 g. The patient was discharged on postoperative day 16. Pathological examination revealed the effect of chemoradiotherapy was Ef2, and viable cells were present in the #4 LN (ypN2).
Conclusion:
While the long-term outcome of this patient is unknown, we believe the trimodality treatment is an option for bulky N2 NSCLC with SVC involvement.
