Survival of Patients after Resection for Lung Cancer

Abstract
The predictive value of staging of primary lung cancer by CT and thoracotomy with respect to survival was assessed in a series of 151 consecutive patients. The new international staging system for lung cancer was used, with an additional indeterminate stage employed for cases in which a definite classification was impossible by CT. The survival rate curves for the stage groups assessed at CT and thoracotomy showed moderate to good parallelism. The patients with tumor stage I at thoracotomy but indeterminate or IIIa at CT had a significantly lower survival rate than those scored stage I at both. It was concluded that a sign of tumor spread obtained at any of the investigations should lead to an active approach, increasing the radicality of surgery or omitting noncurative operations.
