MATERIALS AND METHODS: Retrospective 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. RESULTS: Survival 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. CONCLUSIONS: Survival 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.Inngangur: Skurðaðgerð er helsta læknandi meðferð við lungnakrabbameini. Tilgangur þessarar rannsóknar var að kanna stigun, lífshorfur og forspárþætti lífshorfa hjá sjúklingum sem gengist hafa undir lungnablaðnám vegna lungnakrabbameins á Íslandi. Efniviður og aðferðir: Afturskyggn rannsókn á 213 sjúklingum (meðalaldur 66,9 ár) sem gengust undir blaðnám á Íslandi við lungnakrabbameini öðru en smáfrumukrabbameini (ÖES) á tímabilinu 1999-2008. Æxlin voru stiguð samkvæmt TNM-stigunarkerfi og ein- og fjölþáttagreining notuð til að meta forspárþætti lífshorfa. Niðurstöður: Heildarlífshorfur (Kaplan-Meier) eftir eitt ár og fimm ár voru 82,7% og 45,1%, en enginn lést
