    Background:
    Socioeconomic disparities in survival of patients with lung cancer have been identified in many countries. The aim of this study was to examine determinants of late diagnosis of lung cancer in France.
    
    Methods:
    All patients with a first diagnosis of lung cancer in 2011 in the National hospitals databases were included. Information on gender, age, presence of metastasis at diagnosis and any significant chronic comorbidities (hypertension, diabetes mellitus, renal insufficiency, and other chronic lung diseases) was retrieved. Based on municipality of residence, patients were classified by population density, social deprivation, access to general practitioners and pulmonologists.
    
    Results:
    We identified 41,015 patients newly diagnosed for lung cancer in French hospitals. Mean age at diagnosis was 66.4 (±11.9) years and 72% patients were men. 53% (N=21,613) patients were metastatic at the time of diagnosis. This rate was higher for patients in public compared to private hospitals (56.1% vs 42.9%, p<0.0001) and in community compared to university hospitals (60.2% vs 49.6%, p<0.0001). Multivariate analysis found that metastases at the time of diagnosis were significantly associated with a younger age (55 years or less, OR: 1.22 [95%CI:1.16–1.29]; p<0.0001), a low access to pulmonologists (OR: 1.13 [95%CI:1.04–1.23]; p=0.004), a rural or semi-rural dwelling (OR: 1.07 [95%CI:1.02–1.13]; p=0.004) and deprived areas (OR: 1.06 [95%CI:1.01–1.11]; p=0.01). Of the 8,413 patients (20%) who were initially admitted through emergency room (ER) 68.1% had metastatic tumors. Multivariate analysis showed significantly higher rate of admission through ER at diagnosis in patients from most deprived areas (OR: 1.44 [95%CI:1.37–1.52]; p0.0001), rural or semi-rural (OR: 1.25 [95%CI:1.19–1.32]; p<0.0001), with a low access to pulmonologists and general practitioners (OR: 1.24 [95%CI:1.17–1.30]; p<0.0001 and 1.15 [95%CI:1.08–1.23]; p<0.0001, respectively). Gender (male) and presence of comorbidities were also significant determinants of metastatic disease and admission through ER at diagnosis.
    
    Conclusion:
    A majority of French patients with lung cancer were initially metastatic at the time of diagnosis and 1 out of 5 were diagnosed following admission through ER. Residential socioeconomic indicators and access to general practitioners and pulmonologists were significantly associated with these indicators of poor outcome.
