Study Notes
Oncofetal Antigens
- Produced mainly by normal cells of fetus or placenta, leading to higher levels in mothers and babies compared to healthy adults.
- Production increases in certain tumors in adults.
Tumor Markers
-
α1-Fetoprotein (AFP)
- Used for follow-up of malignant teratoma in conjunction with HCG.
- Used for early detection and follow-up of hepatoma by measuring fucosylated AFP.
Tumor Markers
-
Carcinoembryonic Antigen (CEA)
- Used for follow-up of colorectal carcinoma.
Tumor Markers
-
Human Chorionic Gonadotropin (HCG)
- Used for early diagnosis, detection of CNS metastasis, and follow-up of trophoblastic tissue tumors.
- Used for follow-up of teratoma in conjunction with AFP, specifically for testicular teratoma.
Tumor Markers
-
Placental-like ALP
- Used for monitoring patients treated for seminoma.
