    Abstract:
    BACKGROUND: Even after presumably curative resection the 5-year survival rates are only 60-80% in stage I and 40-50% in stage II NSCLC. Purpose of the present study was the identification of independent clinico-pathological predictors of their survival. METHODS: A retrospective review of 519 consecutive subjects who had undergone attempted curative resection for stage I or II NSCLC was performed. Patients who had received any adjuvant or neo-adjuvant chemo- or radiation therapy were excluded. Primary outcome measure was the duration of overall survival. RESULTS: Median survival was 7.25 years for stage IA, 5.71 years for stage IB and 3.85 years for stage IIB. In univariate analysis, six variables were significantly associated (p-value<0.05) with poorer survival: older age, larger size of the tumor, male gender, surgery other than lobectomy, squamous histology and later stages (stage IB and IIB). In multivariate analysis, age (Hazard ratio=1.06 per year increase in age; p<0.0001), larger tumor size (Hazard ratio=1.54 per doubling of tumor size; p<0.0001), type of surgery (Hazard ratio=1.50 for surgery other than lobectomy; p=0.036), and gender (Hazard ratio=1.45 for male gender; p=0.039) were the predictors of overall survival. CONCLUSIONS: In surgically treated early stage (I and II) NSCLC patients, age, tumor size, type of surgery, and gender are the important predictors of survival.
