CA72-4 is elevated most notably in which cancer?

Explanation:
CA 72-4 is a tumor-associated antigen that can be elevated in several gastrointestinal cancers, particularly mucin-producing ones. Among the cancers listed, the level of CA 72-4 tends to be highest and most notable in pancreatic cancer, making it the best association for this marker in this context. Prostate cancer is typically linked with PSA, thyroid cancer with thyroglobulin, and melanoma with markers like S-100 or LDH, so CA 72-4 is not the characteristic marker for those.
