[Relationship between primary lung cancer and tobacco consumption. Results of the KBP-2010-CPHG study by the French College of General Hospital Respiratory Physicians]. / Relation entre cancer bronchique primitif et consommation tabagique. Résultats de l'étude KBP-2010-CPHG du Collège des pneumologues des hôpitaux généraux.

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. A standardized form was completed at diagnosis and a steering committee checked the completeness of inclusion. RESULTS: Only 10.9% of patients were never-smokers and 89.1% ever-smokers (i.e., current or former smokers). Respectively, 3.7%, 10.7% and 85.6% of ever-smokers consumed/had consumed 1-10, 11-20, and >20 pack-years. Mean smoking duration was 37.5 years. Former smokers had stopped smoking on average 14.8 years previously. Only 20.7% of never-smokers reported that they had been exposed to tobacco smoke passively. At diagnosis, statistically significant differences were found between never- and ever-smokers (P<0.0001) for sex (women: 60.8% vs 18.8%), age (mean: 70.7 years vs 64.9 years), stage (IV: 70.8% vs 58.7%), histology (adenocarcinoma: 68.5% vs 42.6%), EGFR mutation exploration (51.4% vs 28.0%) and positivity (37.0% vs 4.6%). Differences between never- and ever-smokers rose with increasing tobacco consumption. CONCLUSIONS: This study confirms that differences exist between never- and ever-smoker patients presenting with primary lung cancer and shows the impact of the level of tobacco consumption, in particular on histology.

Five-year survival for lung cancer patients managed in general hospitals.

INTRODUCTION: In 2000, the college of pulmonologists of general hospitals undertook an epidemiological study (KBP-2000-CPHG) enrolling all new cases of histologically confirmed lung cancer managed in general hospitals. This paper reports the 5-year survival in these cases. METHODS: Vital status was available for 5447 out of 5667 patients included in the original study. The effect of different prognostic factors on mortality was assessed. RESULTS: At 5 years, 567 patients (10.4%) were still alive. Median survival for the 4880 (89.6%) deceased patients was 7 months. Univariate analysis identified age, smoking history, performance status, histological type and disease stage (TMN classification) as determinants of survival. For non-small cell lung cancer (n=4885) multivariate analysis identified five predictive factors for mortality - age, gender, histological type, performance status and stage. CONCLUSIONS: Five-year survival in lung cancer continues to be poor. As the risk factors for poor outcome at the time of diagnosis are not modifiable and pending, the results of screening studies reduction in mortality must rest on primary prevention.

[Pulmonary mucormycosis: benefit of aerosol amphotericin B?]. / Mucormycose pulmonaire: intérêt des aérosols d'amphotéricine B?

Mucormycosis is an opportunistic fungal infection usually observed in diabetic or neutropenic patients. Prognosis is serious with a high rate of mortality. Intravenous amphotericin B is the gold standard treatment. The main side effect is renal failure. Liposomal amphotericin B (AmBisome(R)) is not nephrotoxic and can be proposed as an alternative treatment although its cost is high. We report a case of mucormycosis in a diabetic woman who developed renal failure after intravenous amphotericin B treatment. AmBisome(R) could not be used for long-term treatment due to its high case. The patient was given nebulized amphotericin B and achieved recovery. This kind of treatment may provide a useful alternative to intravenous amphotericin B.
