Like any elevated tumor marker, elevated AFP by itself is not diagnostic, only suggestive. Tumor markers are used primarily to monitor the result of a treatment (e.g. chemotherapy). If levels of AFP go down after treatment, the tumor is not growing. In the case of babies, after treatment AFP should go down faster than it would normally. A ...
Very high AFP levels may be subject to hooking (see Tumor marker), which results in the level being reported significantly lower than the actual concentration. [29] This is important for analysis of a series of AFP tumor marker tests, e.g. in the context of post-treatment early surveillance of cancer survivors, where the rate of decrease of AFP ...
Diagnosis of EST in pregnant women and in infants is complicated by the extremely high levels of AFP in those two groups. Tumor surveillance by monitoring AFP requires accurate correction for gestational age in pregnant women, and age in infants. In pregnant women, this can be achieved simply by testing maternal serum AFP rather than tumor ...
Tumor marker Associated tumor types Alpha fetoprotein (AFP) germ cell tumor, hepatocellular carcinoma [9] CA15-3: breast cancer [10] CA27.29: breast cancer [11] CA19-9: Mainly pancreatic cancer, but also colorectal cancer and other types of gastrointestinal cancer. [12] CA-125
A surge in the plasma levels of human chorionic gonadotropin and alpha-fetoprotein is indicative of OGMTs. [1] Lactate dehydrogenase, alkaline phosphatase and cancer antigen 125 might potentially increase as well. [24] To visualize the location and morphology of the tumor, transvaginal ultrasonography is usually employed. [1]
There may be elevations in serum human chorionic gonadotropin (hCG) and alpha fetoprotein (AFP) levels but it would be in association with other tumors, (e.g. yolk sac tumor) because they themselves do not produce the serum markers. [4] At surgery, there is extension of the tumour beyond the ovary in forty percent of cases.
