tumor marker

Головна / Dictionary / tumor marker

Tumor markers are substances detectable in elevated levels in blood, urine, or tissues of some cancer patients, produced either by the tumor or the body in response.​

Limitations in Diagnosis

These markers lack specificity, as levels rise in non-cancerous conditions, and sensitivity, since early-stage cancers often show normal levels; thus, they require combination with biopsies or imaging for diagnosis.​

Clinical Applications

Post-diagnosis, they monitor treatment efficacy, assess disease stage and progression, predict prognosis, and detect recurrence. Common examples include AFP (liver cancer), CEA (colorectal), PSA (prostate), CA-125 (ovarian), HCG, LDH, and NSE.
