What is the full form of LDH in the context of tumor markers?

In the context of tumor markers, LDH stands for Lactate dehydrogenase. This enzyme plays a crucial role in the process of glycolysis, which is the metabolic pathway that converts glucose into energy. In oncology, LDH is often assessed because it can indicate the presence of tissue damage and is associated with various types of cancers.

Elevated levels of LDH in the blood can reflect tumor burden, disease progression, or response to treatment, making it a useful biomarker in certain cancers such as lymphoma and testicular cancer. The measurement of LDH levels provides valuable insights into patient prognosis and treatment strategies.

The other options do not accurately represent what LDH stands for in the context of oncology or tumor markers, which is why they do not serve as correct alternatives.
