To be the gold standard for monitoring, a biomarker must have a strong, consistent, and predictable quantitative relationship with the total body burden of viable tumor. Its serum level should rise and fall proportionally as the tumor grows or shrinks. This allows clinicians to reliably assess treatment efficacy and detect recurrence early based on trends in the biomarker level, often before changes are visible on imaging.
