Does Beclin-1 predict disease-free interval for primary tumors alone?

Explanation:
Beclin-1’s role in autophagy makes it an interesting biological marker, but its expression in the primary tumor does not reliably forecast how long a dog will remain disease-free after initial treatment. Disease-free interval for primary tumors depends on many factors, including micrometastatic disease, tumor biology, surgical margins, and treatment response, and Beclin-1’s prognostic value varies with context. Because there isn’t a consistent, universal link between Beclin-1 levels in the primary tumor and recurrence risk across tumor types and scenarios, it does not serve as a dependable predictor of disease-free interval for primary tumors.
