2 Pneumonectomy after induction Rx Optimal treatment strategies for operable advanced stage lung cancer is still uncertain In patients with locally advanced lung cancer, improved resectability has been seen after concurrent chemoradiotherapy at, Chest x-ray courtesy of David J. Sugarbaker, M.D.

3 Challenges with pneumonectomy after induction therapy Chemoradiation may reduce pulmonary function and can result in significant fibrosis around key hilar structures Induction therapy may increase patient susceptibility to pulmonary edema and impair ability of bronchial stumps to heal Known complications/morbidity associated with pneumonectomy after induction therapy include: ARDS, pulmonary edema, broncho-pleural fistula, arrhythmias, prolonged air leak, vocal cord paralysis, and empyema Krasna MJ, Gamliel Z, Burrows WM, Sonett JR, Kwong KF, Edelman MJ, et al.

9 Allen et al, 2008 Retrospective review, 73 pts Patients underwent pneumonectomy after induction chemort 6% 30 day mortality, 10% 100 day mortality Allen AM, Mentzer SJ, Yeap BY, Soto R, Baldini EH, Rabin MS, et al.

10 Allen et al, Conclusions Lymph node downstaging after induction chemort leads to improved survival Not all pts had N2 nodes so lymph node downstage rate could not be assessed in their study Trimodality approach should be done at high volume centers at, Allen AM, Mentzer SJ, Yeap BY, Soto R, Baldini EH, Rabin MS, et al.

12 Daly et al, 2006 Death in 4 pts, 13.3% Median survival 22 months, 5 year 33% 3yr survival after high-dose RT and concurrent chemotherapy without surgery as definitive tx for stage IIIA-N2 disease in INT % 55% with N2 nodal downstaging but no correlation with survival at, Daly BD, Fernando HC, Ketchedjian A, Dipetrillo TA, Kachnic LA, Morelli DM, et al.

14 29/103 pts (28%) downstaged to N0, 5 year survival of 35.8% 74/103 pts (72%) pts with persistent disease with N1/N2 status, 5 year survival of 9% Recommend restaging with thoracoscopy, PET, lymph node biopsy via EUS at Bueno R, Richards WG, Swanson SJ, Jaklitsch MT, Lukanich JM, Mentzer SJ, et al.

15 Restaging the mediastinum after induction therapy will allow the surgeon to prevent resection in patients with less survival benefit Methods to restage mediastinum include: VATS Redo mediastinoscopy PET EBUS at

17 Jaklitsch et al, pts underwent VATS: 3 negative stations confirmed in 7 pts Persistent N2 in 16 pts 4 pts with pleural carcinomatosis 20 pts with obliterated nodal stations Recommend PET/EBUS as adjuncts in restaging Jaklitsch MT, Gu L, Demmy T, Harpole DH, D Amico TA, McKenna RJ et al.

20 Nasir et al, pts with negative EBUS, 3 underwent mediastinoscopy and 2 with persistent nodal disease 22 patients underwent thoracotomy and 1 pt was found to have N2 disease Negative predictive value of 88% Nasir BS, Bryant AS, Minnich DJ, et al.

21 Conclusions Pneumonectomy after induction therapy is feasible and safe Careful patient selection, N2 disease status Restage patients after neoadjuvant therapy Should be performed by experienced surgeons at high volume centers at,
