About this trial
This observational, retrospective study aims to understand the treatment patterns and outcomes of patients with pulmonary and extra-pulmonary neuroendocrine carcinomas (NEC) in Latin America (Brazil, Mexico, Argentina, and Peru). The research will collect data from medical records to analyze factors like patient demographics, diagnosis methods, tumor characteristics, treatment approaches, and disease progression. The study is non-interventional, meaning patient care will follow standard clinical practice, with data gathered via an electronic system.

Treatment groups
Trial outcomes
Primary outcomes
Patterns of Initial Cancer Treatment: number of participants treated within vs. outside high-volume sites and associated treatment characteristics
Treatment patterns will be analyzed descriptively using tables and graphs to illustrate the distribution of patients receiving initial cancer treatment within versus outside high-volume treatment centers. Key characteristics of the initial treatment will be assessed.
Event-free survival (EFS)
defined as time from diagnosis until relapse, death, or definitive failure of treatment strategy that implicates failure of curative-intent treatment \[for patients treated with curative intent\]. Participants who are lost to follow up or reach the study end will be censored at their last date of contact.
Time to treatment failure (TTF)
in first and second-line: defined as time from first dose of treatments until date of discontinuation of treatment for any reason, including progression of disease, treatment toxicity, and death. Participants who are lost to follow up or reach the study end will be censored at their last date of contact
Progression-free survival (PFS)
defined as time from treatment initiation until progression or death \[for patients treated with palliative intent\]. Participants who are lost to follow up or reach the study end will be censored at their last date of contact.
