Abstract

Although locally advanced lung cancer frequently necessitates extended resections to preserve a chance for cure, a higher morbidity is associated with extended resections. It is not known whether the increased morbidity is of relevance for the long-term outcome. It also remains unclear whether exclusion of certain patients according to their risk factors can diminish mortality in these patients. This study therefore investigated whether certain risk factors predispose patients undergoing extended pulmonary resections to increased morbidity or mortality. It also assessed the long-term survival. The cases of 126 consecutive patients with locally advanced lung cancer (stage T3 or T4) were prospectively documented. Seventy-five percent of the patients required an extended resection and 25% a nonextended resection. Extended resections were associated with a significantly increased overall morbidity ( p < 0.002). However, mortality, severe complications, or multiple complications were not significantly increased after extended resections. No risk factor predisposed to an increased mortality. Risk factors that were associated with particular postoperative complications were pathologic ergonometry ( p < 0.002), a positive cardiac score ( p < 0.003), coronary artery disease ( p = 0.021), and an increased pulmonary risk score ( p < 0.05). Overall 3-year survival was 31%. Patients undergoing extended resections for stage T3 or T4 tumors with no residual tumor (70% of the patients) showed a 3-year survival of 33%. We conclude that postoperative mortality cannot be reduced by excluding patients on the basis of particular risk factors from operations that require extended resections. If a patient is considered to be eligible to undergo pulmonary resection, he or she can be considered to be eligible to undergo extended pulmonary resection. Because prognosis is dismal in nonresected locally advanced lung cancer, we recommend an aggressive surgical approach.(J T HORAC C ARDIOVASC S URG 1995;110:386-95)
