This is often termed isolated biomarker elevation or marker-only recurrence. It describes a situation where a tumor marker (e.g., PSA after prostatectomy, CA 125 after ovarian cancer treatment) becomes elevated on serial testing, but conventional imaging (CT, MRI, bone scan) shows no evidence of metastatic disease. This state indicates the presence of microscopic or low-volume disease that is below the detection limit of standard scans. It often prompts more sensitive imaging (e.g., PET-CT) or closer surveillance.
