Smoking status at diagnosis and histology type as determinants of long-term outcomes of lung cancer patients

Abstract

Smoking status at time of surgery does not effect long-term survival in patients with squamous cell carcinoma. Smoking status makes a significant difference to the long-term outcomes of patients with adenocarcinoma even after adjustment for their risk factors. This implies that a histological classification of adenocarcinoma may incorporate genetically diverse adenocarcinomas with regard to prognosis.
