BACKGROUND: Even among @entity1 considered to be functionally eligible for major lung resection, some experience postoperative @entity1353 . Based on our previous study with quantitative computed tomography (CT), we hypothesized that postoperative @entity1353 is associated with the collapse of the remaining lung, and thus, prediction of the postoperative lung volume may contribute to risk assessment for postoperative @entity1353 . METHODS: We measured the @entity358 and functional lung volume (FLV) separately on whole lung CT using an image analysis software in 290 @entity1 undergoing major lung resection for cancer between January 2006 and December 2012. The postoperative FLV was predicted by a stepwise multiple regression analysis. RESULTS: Fourteen @entity1 @entity86 (complicated group), five of them presented with @entity1576 . The postoperatively measured FLV was significantly lower in the complicated group than in the control group (P  <  0.01). The postoperative FLV could be calculated using preoperative variables, including the forced vital capacity, number of resected segments, FLV, and @entity358 . The predicted postoperative FLV was significantly lower in the complicated group than in the control group (P  <  0.01, area under the curve  =  0.78; sensitivity 86%; specificity 73%). The predicted postoperative FLV was also useful in distinguishing complicated @entity1 from matched-control @entity1 who had similar preoperative pulmonary function (P  =  0.02). CONCLUSIONS: @entity86 is likely accompanied by a collapse of the remaining lung. Quantitative assessment of the lung morphology on preoperative CT is useful to screen for @entity1 at risk of postoperative @entity1353 .
