[Relationship between primary lung cancer and tobacco consumption. Results of the KBP-2010-CPHG study by the French College of General Hospital Respiratory Physicians].

Introduction: The Collège des Pneumologues des Hôpitaux Généraux has performed a prospective multicentre epidemiological study which aims to describe the baseline characteristics of all new cases of primary lung cancer histologically or cytologically diagnosed in 2010 and followed-up in the respiratory department of general hospitals. The present publication compares the characteristics of these presentations according to their smoking history.

Methods: Seven thousand and fifty-one adult patients were included from 104 respiratory departments.

[Pituitary metastasis revealing a lung cancer].

Introduction: Pituitary metastases are rare and difficult to diagnose. Their optimal approach and management remains to be defined.

Case Report: We report the case of a 56-year-old patient suffering from squamous cell lung carcinoma who developed pituitary metastasis with secondary hypopituitarism, the symptoms of which were initially attributed to depression.

Early detection of lung cancer: role of biomarkers.

Early detection of lung cancer requires none or few invasive techniques. Distal lung cancer (40% of the cases in most European countries) can be sensitively detected by spiral computed tomography. Theoretically, in 60% of cases, the proximal lesions (main to segmental bronchi, accessible by bronchoscopy) should be able to be detected by sputum cytology.
