The prognostic significance of modified frailty index-5 in patients undergoing pneumonectomy for lung cancer.

Objectives: In some centrally located lung cancers, complete excision of the mass cannot be achieved with parenchymal-sparing procedures and pneumonectomy may be required. The mortality and morbidity rates of pneumonectomy were reported to be considerably high. Here, we investigated the effectivity of modified frailty index-5 (MFI-5) in patients undergoing pneumonectomy for non-small cell lung cancer.
