[Prognostic importance of lactate dehydrogenase (LDH) in oncology].

Glycolysis is increased in most of the malignant cells, providing the largest proportion of energy needed for cell proliferation. Lactate dehydrogenase (LDH) catalyses the reversible process of pyruvate to lactate in anaerobic condition. LDHA isoenzyme expressed mainly by malignant cells, significantly increases lactate formation. Lactate induces the proliferation of oxygenated malignant cells, angiogenesis, and inhibits the innate and adaptive immune responses. Baseline serum LDH elevation correlates with shorter survival. The authors review the relevant studies exploring the correlation between LDH elevation and the prognosis of malignant diseases. Orv Hetil. 2017; 158(50): 1977-1988.
