ObjectiveTo study the impact of TNM stage and various preoperative functional parameters on survival in patients who underwent lobectomy for non-small cell lung cancer (NSCLC) in Iceland from 1999 to 2008.Materials And MethodsRetrospective study including 213 patients (mean age 66.9 yrs, equal male/female ratio) that underwent lobectomy for NSCLC. Tumors were staged by the TNM staging system, survival was estimated by the Kaplan-Meier method and prognostic factors of survival studied using the Cox proportional hazards regression model.ResultsSurvival at 1 year was 82.7% and 45.1% at 5 years. Operative mortality at 30 days was 0%. Most tumors were found to be in stage I (59.6%) or stage II (17.8%) and 7% were stage IIIA, whereas 14.6% were in stage IIIB or IV. Using multivariate analysis; advancing stage, increasing tumor size, reduced lung function and history of arrhythmia, predicted worse survival, whereas adenocarcinoma histology was a positive prognostic factor (HR 0.5, p=0.002) when compared to other histological types.ConclusionsSurvival for patients undergoing lobectomy for operable non-small cell lung cancer in Iceland is comparable with other studies. Advanced stage, tumor size, reduced lung function and arrhythmia were negative predictors of survival, but in contrast to many but not all studies adenocarcinoma histology predicted a better prognosis compared to other tumor types.
