RESUMEN
INTRODUCTION: The French college of general hospital respiratory physicians (CPHG) has conducted 10 years apart two prospective observational studies to assess changes in the primary lung cancer epidemiology and outcomes, including 1-year mortality. METHODS: In 2000 and 2010, all volunteer adult patients followed in the respiratory department of general hospitals participating in the study were consecutively included if their lung cancer was histologically or cytologically diagnosed between 01 January and 31 December (sample date). Their vital status at least 1 year after inclusion and date of death (if applicable) were collected. RESULTS: Respectively, 5667 and 7051 patients were included in the study in 2000 and 2010 and vital status of 5441 (96.0%) and 6981 (99%) patients known. One-year mortality rate was 61.8% in 2000 and 56.4% in 2010 (P<0.0001). Mortality rate significantly decreased from 2000 to 2010 in non-small-cell lung cancer (60.7% vs. 55.2%; P<0.0001) but not in small-cell lung cancer (66.9% vs. 64.2%; P=0.22). The year of diagnosis was an independent risk factor of mortality (OR=0.84; 95% CI: 0.77-0.91; P<0.0001). CONCLUSION: Although it remains low (43.6% in 2010), life expectancy at 1 year for patients with lung cancer has improved in 10 years. Five-year results are expected to show whether this improvement is maintained or not over time.

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.

INTRODUCTION: The diagnosis of chronic obstruction of the pulmonary artery is difficult. We present the case of a woman with an invasive, undifferentiated carcinoma of the pulmonary artery. CASE REPORT: A 61 year old woman complained of increasing dyspnoea. This was evaluated by computed tomography which showed a defect in the main pulmonary artery. There was no clinical or radiological improvement following anticoagulant treatment for two months. A repeat CT scan showed a persisting intravascular defect and the diagnoses considered included post-embolic pulmonary arterial hypertension and angiosarcoma. A surgical biopsy was performed and pericardial and aortic tumour nodules were found during the operation. The pathological examination revealed undifferentiated carcinoma. Further investigations failed to reveal the primary site. CONCLUSION: Invasion of the pulmonary artery by angiosarcoma or other tumour is part of the differential diagnosis of chronic thromboembolic disease. The diagnosis rests on histology obtained by an intravascular or surgical procedure. Complete surgical excision may be possible in angiosarcoma but it was impossible in our patient. The patient died despite two courses of chemotherapy and targeted therapy with erlotinib.
