CA72-4 is elevated in which cancer?

CA72-4 is elevated in which cancer?

• A. Pancreatic cancer
• B. Colorectal cancer
• C. Stomach cancer
• D. Lung cancer

Answer: (A)

CA72-4 is a tumor-associated marker often elevated in gastrointestinal malignancies, with meaningful associations to pancreatic and gastric cancers. Among the options given, it is most consistently linked to pancreatic cancer in many URR-style questions, making it the best match. This marker is less specific and is not routinely relied upon for colorectal or lung cancers, where other markers (like CEA or CA19-9) are typically more informative. It can be elevated in stomach cancer as well, but the question’s context points to pancreatic cancer as the classic association for CA72-4.
