Overall survival is determined by counting deaths from any cause after a cancer diagnosis, so it uses deaths from all causes to reflect how long patients live overall. This approach records every death, regardless of its cause, providing a direct picture of longevity in the real world and avoiding reliance on how death is attributed to cancer. It can be influenced by deaths from other causes, but that is exactly what makes it a true measure of the total mortality risk after diagnosis.

In contrast, cause-specific survival counts only deaths attributed to cancer (censoring other deaths), so it focuses on cancer control rather than overall longevity. Relative survival and net survival are adjusted concepts that estimate cancer survival by comparing observed outcomes to what would be expected in the general population, rather than using all-cause deaths directly. Thus, the measure that uses deaths from all causes and reflects overall survival is observed all-cause (overall) survival.
