Abstract
ObjectiveThe aim of this work is to study the survival of lung cancer patients treated at a referral hospital in Zaragoza (Spain). Material and methodThe Kaplan-Meier test was used to calculate observed survival. The automatic calculation of the Catalan Institute of Oncology was used to analyse relative survival. ResultsMean survival time was 25.74 months. There was no difference when comparing age groups (P=.151), gender (P=.369), and histological type of tumour (P=.086). Survival by stage of the disease at diagnosis revealed statistically significant differences (P<.001). Relative survival 5 years after diagnosis for the group analysed was 14%. Survival was higher for men (15.5%), in patients under 60 (16.7%) and squamous tumours (18.7%). ConclusionsSurvival by tumour stage was in line with the TNM Staging System for Lung Cancer. These results suggest that overall survival rate for lung cancer in Zaragoza remains very low in the long term, and this depends on the stage of the disease at diagnosis.
