Survival of patients after resection for lung cancer. Predictive value of staging by CT vs thoracotomy.
OBJECTIVE
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.


METHODS
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.


RESULTS
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.
