Video-assisted thoracoscopic lobectomy for clinical stage I non-small cell lung cancer: experience with 111 consecutive patients demonstrating comorbidity.

Abstract The outcomes of video-assisted thoracoscopic lobectomy for clinical stage I non-small cell lung cancer (NSCLC) patients with comorbidities were examined to determine the technical feasibility and safety of this procedure. Between January 2002 and December 2007, 111 consecutive patients with suspected stage I lung cancer, who individually had one or more comorbidities cited in the modified Kaplan-Feinstein Index, were scheduled for a video-assisted thoracoscopic lobectomy. The demographic, perioperative, and outcome variables were assessed. One hundred of 111 patients had non-small cell lung cancer. Ninety-nine patients underwent successful video-assisted thoracoscopic lobectomies, while there was one conversion because of a hemorrhage from the pulmonary artery in the early stage. Including this one conversion, no patients required a blood transfusion during surgery or postoperatively. There were no intraoperative or in-hospital deaths. No complications occurred in 78 (78.8%) of 99 patients. Only one patient (1.0%) with a Kaplan-Feinstein Index Score of severe grade contracted pneumonia indicating grade 3 (severe), whereas the remaining 20 patients had grade 1 (mild) or 2 (moderate) complications. At a median follow-up of 40 months, the overall 3-year survival rates for postoperative stage IA (N.=52); IB (N.=26); and II or more (N.=21) were 100%; 78%; and 71%, respectively. A video-assisted thoracoscopic lobectomy is therefore considered to be a feasible and safe procedure for clinical stage I NSCLC even in patients with comorbidities.
