Elevated alpha-fetoprotein (AFP) is seen in which conditions?

• A. Ovarian cancer, endometriosis, and lung cancer
• B. Prostate cancer
• C. Pancreatic cancer
• D. Colorectal cancer

Answer: (A)

Alpha-fetoprotein rises most clearly with hepatocellular carcinoma and germ cell tumors, especially yolk sac tumors. It is produced by fetal liver and yolk sac, and in tumors that resemble these tissues, AFP can be secreted into the blood. Pregnancy also causes a normal, physiologic rise. In the ovaries, AFP elevation occurs when the tumor is a germ cell type, such as a yolk sac tumor or other AFP-secreting ovarian germ cell neoplasms. It is not a typical marker for ordinary epithelial ovarian cancers or for endometriosis. Pancreatic, colorectal, or prostate cancers do not usually raise AFP, though rare cases can show mild increases. So, elevated AFP fits best with conditions that involve AFP-secreting tissues, particularly hepatocellular carcinoma and yolk sac-type ovarian germ cell tumors; endometriosis and most common solid tumors like colorectal or pancreatic cancer are not typical AFP producers.
