Traditional markers, such as albumin (ABL) (5), total protein (TP) (6), total cholesterol (TCH) (7), glucose (GLU) (8), lactate dehydrogenase (LDH) (9), electrolytes (10), and granulocytes (11), are often used to evaluate the nutritional status of cancer patients (12–16), with ALB and TP being the most commonly used indicators for assessing nutritional status (17, 18). The gene discussed is ALB; the disease is cancer.
