Lung cancer is one of the commonest and most lethal cancers throughout the world. Among the subtypes of lung cancer, non-small cell lung cancer (NSCLC) is the most prevalent, accounting for 85% of all new cases. The epidemiological and pathological profile of the disease differs among various ethnicities and geographical boundaries. Therefore, the aim of this study was to analyse the current clinico-pathological profile and factors affecting survival of Egyptian NSCLC patients at the department of Clinical Oncology and Nuclear medicine in Ain Shams University hospitals.


All patients with pathologically proven primary NSCLC in the period from 2012 to 2014 were included for analysis. Data from records of 195 cases were available for clinicopathological evaluation during the study period. Treatment received and outcome was collected.


The mean age at diagnosis of the study population was 59 years, Male to female ratio was 3.6:1, 71.2% of cases were current or x-smokers, 44.6% of patients had ECOG performance status 1. The most common symptom at presentation was dyspnea and right upper lobe was the most common tumor site. Adenocarcinoma was the most common histological subtype representing 62% of cases. Most common stage at diagnosis was stage IV (56.4%) and the most common site of metastasis was bones. Statistically significant improvement in overall survival rate and progression free survival rate was found in the following groups: female sex, PS 1 or 2, never smokers, grade II tumors, lower tumor size, less lymph nodal stations involvement, lower stage at diagnosis, single versus multiple metastatic sites and response to definitive treatment.


The present analysis suggested that lung cancer incidence in Egypt is less than most of the western countries. Patients presented at younger age compared to other areas of the world. Most of the patients had advanced disease at presentation. Adenocarcinoma was the most common histological subtype. Female sex, better performance status, never smokers, smaller tumors, less lymph nodal affection, earlier stage at diagnosis, fewer metastatic sites and response to definitive treatment have a statistically significant better OS and PFS.
