Abstract
Non-small cell lung carcinoma (NSCLC) is the main cause of cancer-related death in Latin America. Nonetheless, there is insufficient information regarding its epidemiology, treatment and outcomes in the region. The goals of this study are to describe disease characteristics, treatment patterns and survival for advanced NSCLC in Latin America. LACOG 0116 LATINO Lung is a prospective cohort study aiming to include approximately 800 patients with advanced stage NSCLC (stage III/IV at diagnosis or distant relapse of early-stage disease) from 24 sites in Brazil, Argentina, Mexico, Colombia and Chile. All consecutive newly diagnosed patients seen at each site will be invited to participate. Data on socioeconomic and demographic characteristics, medical/oncologic history and clinical-pathological characteristics will be collected at baseline. Thereafter, patients will be followed every 6 months for 3 years in order to gather information regarding treatment patterns and sequencing, reasons for treatment discontinuation, response to treatment, disease progression and overall survival. Data will be collected during medical visits or telephone calls and by medical charts review. Primary endpoint is to estimate the overall survival. Descriptive analysis of treatments and outcomes are planned. Multivariable regression methods will be applied to assess possible independent prognostic or predictive factors. As of April 3rd, 2019, 107 patients have been included, all of them within 16 sites in Brazil. Currently, there are 2 sites from Argentina, 2 from Mexico, 3 from Colombia and 1 from Chile awaiting regulatory approval to begin enrollment. Recruitment is planned to last until December 2019, when the estimated sample size will be achieved. LACOG 0116 LATINO Lung is the first Latin American lung cancer prospective cohort study that will generate real-world data on NSCLC. The study may identify gaps and inequities in a diverse population of NSCLC in Latin America and consequently raise the need for improvement and individualized approach of lung cancer care in the region.
