Carcinoembryonic Antigen (CEA)
What tumor marker is used for the early diagnosis, detection of CNS metastasis, and follow-up of trophoblastic tissue tumors?
Human Chorionic Gonadotropin (HCG)
In addition to Human Chorionic Gonadotropin (HCG), which other tumor marker is used for the follow-up of malignant teratoma?
α1-Fetoprotein (AFP)
Which tumor marker is specifically monitored in patients treated for seminoma?
Placental-like ALP
For the early detection and follow-up of hepatoma, which specific form of AFP is measured?
Fucosylated AFP
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.
