Late events and clinical prognostic factors in stage I non small cell lung cancer.
Two hundred and forty six consecutive patients with pathological T1-2 N0 M0 non-small cell lung cancer were reviewed. Median follow-up was 79 months (range 3-144). So far, 110 patients have relapsed (45.6%). Actuarial median time to recurrence was 26 months in the 45 patients with thoracic relapses versus 12 months of the 65 metastatic (P<0.001). Disease-free survival (DFS) rates at 5 and 10-year were 62 and 49%, respectively. Fifteen percent of the patients (20) disease-free at 5 years relapsed in the following years; of them, 40% (8) underwent new surgery. Extrapulmonary malignancies other than lung cancer occurred in 27 patients (11.2%), mostly (21) after the diagnosis of lung cancer; in this subset median time to occurrence was 52 months (range 8-105) with a rate of occurrence remaining constant over the years after operation. Univariate and multivariate analysis demonstrated that large cell histology, lower performance status (PS) and presence of symptoms were unfavourable prognostic factors both for DFS and survival.


CONCLUSIONS
this study found a non-negligible proportion of late events and identified some prognostic factors (PS, presence of symptoms and large cell histology) using information obtained from routine data.
