ABSTRACT
The WORLD07 study was a female-specific database, to prospectively characterise the clinical, histological, molecular and treatment-related features in Spanish women with lung cancer. Data were collected from patients' medical records and patient interviews from October 2007 to December 2012. A total of 2,060 women were analysed: median age, 61.3 years; white, 98.6%; postmenopausal, 80.2%; and no smokers, 55% including never smokers and ex-smokers. A family history of cancer was found in 42.5% of patients, 12.0% of patients had had a previous history of cancer (breast cancer, 39.7%). Most patients (85.8%) were diagnosed of non-small-cell lung cancer (NSCLC), most commonly reported with adenocarcinoma (71.4%), which was stage IV at diagnosis in 57.6%. Median overall survival (OS) for the entire population was 24.0 months, with a 1- and 2-year survival rate of 70.7% and 50.0% respectively. Median OS in patients with small-cell lung cancer was 18.8 months versus 25.0 months in patients with NSCLC (p = 0.011). Lung cancer appears to be a biologically different disease in women. By collecting prospective information about characteristics of women with lung cancer attending university hospitals in Spain, we hope to highlight the need to develop strategies based on gender differences and influence future healthcare policy.

The WORLD07 study characterizes lung cancer in Spanish women. This analysis investigated lung cancer features in never-smoking women. Of 2072 women recruited, 2035 were analyzed. Patient characteristics and demographics were similar for current/former smokers and never smokers. Among never smokers, 38.3% were exposed to passive smoking. Non-small-cell lung cancer was the most common type (78.8% of current/former smokers and 96.1% of never smokers) and adenocarcinoma the most common histology (69.1% and 83.4% respectively). There was a high incidence of lung cancer in Spanish never-smoking women and a high proportion (about 50%) had mutant epidermal growth factor receptor.
