In which context is Beclin-1 a predictive biomarker according to the data?

Beclin-1 acts through autophagy, a process that can alter how tumor cells cope with stress from therapy. A predictive biomarker is one that forecasts how a tumor will respond to a specific treatment, not just the disease course in general. The data indicate that Beclin-1’s expression levels are associated with recurrence or treatment response only when tumors receive adjunctive therapy after the primary treatment. In untreated tumors, Beclin-1 does not reliably predict outcomes, and it does not serve as a universal biomarker for all MCTs. So the favorable context is its predictive value specifically in tumors that are treated with adjunctive therapy.
