biochemical monitoring
Serial measurement of tumor markers and hormones to assess treatment response and disease progression in endocrine tumors.
Full Definition
Biochemical monitoring involves systematic tracking of specific biomarkers, tumor markers, and hormone levels to evaluate treatment efficacy and detect disease recurrence in endocrine malignancies. Key parameters include chromogranin A and specific hormones in functional NETs, calcitonin and CEA in medullary thyroid carcinoma, and catecholamine metabolites in pheochromocytoma. The frequency and selection of markers depend on tumor type, treatment modality, and clinical context. Biochemical responses may precede radiological changes and provide early indicators of therapeutic success or resistance. Interpretation requires understanding of marker limitations and potential confounding factors.
Usage
Usage note: Specify which markers are being monitored for clarity.
In Context
- "Biochemical monitoring showed declining chromogranin A levels following initiation of somatostatin analog therapy." — Follow-up assessment
- "Rising calcitonin on biochemical monitoring prompted imaging to assess for recurrent medullary thyroid carcinoma." — Surveillance protocol
