Management of italian patients with advanced non-small-cell lung cancer after second-line treatment: Results of the longitudinal phase of the life observational study

Results The longitudinal phase was conducted between January and August 2012. Of 464 patients who began second-line therapy outside of clinical trials within the baseline evaluation, 56 (12.1%) were still receiving second-line therapy at the end of the observation period and 17 (3.7%) withdrew during or after second-line therapy. Of the remaining 391 patients, 158 (40.4%) received third-line treatment outside of clinical trials: 93 received a third-line chemotherapy and 65 a targeted agent. The main reason for interrupting third-line treatment was disease progression or death. During the same observation period, 25 of 113 patients who completed a third-line therapy received a fourth line of treatment. From diagnosis of NSCLC to the end of observation, biomarkers were tested in 323 patients (59.7%): epidermal growth factor receptor mutations in 315 (58.2%), Kirsten rat sarcoma 2 viral oncogene homolog (KRAS) mutations in 83 (15.3%) and Anaplastic lymphoma kinase (ALK) translocation in 84 (15.5%).Conclusion In Italian clinical practice, the proportion of patients with advanced NSCLC receiving more than 2 treatment lines of therapy is not negligible.Patients and Methods In the longitudinal phase, described here, the primary aim was to determine the proportion of patients receiving third-line therapy among those who received second-line active treatment according to clinical practice. The proportion of patients receiving further treatment lines was also estimated.Introduction/Background Patients with advanced NSCLC who experience disease progression after second-line therapy might receive further active treatment. LIFE was an Italian cohort multicenter observational study composed of a cross-sectional and a longitudinal phase
