Video-Assisted Thoracic Surgery Lobectomy for Non-small Cell Lung Cancer in Patients with a Charlson Comorbidity Index Score of Two or More

IntroductionWe evaluated the feasibility and safety of the video-assisted thoracic surgery (VATS) lobectomy for non-small cell lung cancer (NSCLC) in patients with comorbidity.MethodsBetween April 2000 and December 2006, a prospective database of 58 consecutive patients undergoing a VATS lobectomy for NSCLC, who had a Charlson comorbidity index score of 2 or more, was retrospectively analyzed. The demographic, perioperative, histopathologic, and outcome variables, including the recurrence and survival, were assessed.ResultsThe VATS lobectomy was successfully performed in 57 patients (16 women and 41 men; median age, 70 years). Twenty-three patients (40.4%) were aged 75 years or older. The total score of the Charlson comorbidity index was as follows: 2 in 26 patients, 3 in 13 patients, 4 in 12 patients, 5 in five patients, and 6 in one patient. None of the patients required a blood transfusion during surgery or during the postoperative course. We observed no intraoperative or in-hospital deaths, and no complications occurred in the 45 patients (78.9%). At a median follow-up of 34 months, a recurrence was observed in five patients who had advanced stages: a local recurrence in one and a distant recurrence in four. The overall 5-year survival rates for postoperative stage IA (n = 25) and IB (n = 16) were 100% and 94%, respectively.ConclusionsWe believe that a VATS lobectomy is a feasible and safe procedure for NSCLC in patients with comorbidity because this modality demonstrates an acceptable morbidity and a favorable oncologic outcome.
