Which enzyme is increased in persons with prostate and small-cell lung cancer?

The enzyme that is typically increased in individuals with prostate cancer and small-cell lung cancer is lactate dehydrogenase (LDH). Elevated levels of LDH can indicate tissue breakdown or increased cellular turnover, which is common in various malignancies, including prostate and small-cell lung cancer.

While creatine kinase-1 (CK-1) is more commonly associated with muscle damage and conditions related to the heart or skeletal muscle, it is not specifically linked to prostate or small-cell lung cancers. Gamma glutamyl transferase (GGT) is generally related to liver function and bile duct issues. Amylase is primarily associated with pancreatic function, and its elevation is more relevant in diseases affecting the pancreas rather than specific cancers like prostate or small-cell lung cancer.

Therefore, it is important to recognize that while other enzymes may elevate in different conditions, LDH is the enzyme that has a stronger association with the presence of these specific cancers.
