What this trial studies

This multicenter observational study aims to collect data on lung cancer patients across Canada, focusing initially on specific molecular alterations such as ALK, EGFR, and ROS1. By utilizing both retrospective and prospective methods, the study seeks to understand the natural history, treatment patterns, and outcomes of various lung cancer subgroups. The goal is to generate real-world data that reflects how treatments and outcomes translate from clinical trials to everyday practice. The study will expand to include other rare molecular alterations in its second year.

Who should consider this trial

Good fit: Ideal candidates are Canadian adults aged 18 years or older who have been diagnosed with lung cancer since 2006.

Not a fit: Patients who are unable to provide informed consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the treatment and management of lung cancer, leading to improved patient outcomes.

How similar studies have performed: Other studies have successfully utilized similar observational approaches to gather real-world data on cancer treatment and outcomes.
