Albumin is a protein found in the blood that plays a crucial role in maintaining various bodily functions, including blood volume, blood pressure, and the transport of hormones, vitamins, and minerals.
Associated with improved prognosis in certain types of cancer.
May be a marker of improved nutritional status and reduced inflammation in cancer patients.
Albumin is the most abundant plasma protein, synthesized by the liver. Biologically, it maintains oncotic pressure, transports hormones/drugs, and buffers redox and metabolic stress.
In oncology, serum albumin is a host-state biomarker, not a tumor marker.
What Low Albumin Means in Cancer
-Hypoalbuminemia reflects a convergence of cancer-relevant processes:
-Chronic inflammation (IL-6 suppresses hepatic albumin synthesis)
-Catabolism and cachexia
-Poor nutritional reserve
-Liver synthetic stress
-Advanced systemic disease
Low albumin is therefore a global severity signal, not a single-pathway readout.
ALB (Albumin) — Major plasma transport protein synthesized primarily by the liver. Albumin maintains plasma colloid osmotic pressure and binds/transports fatty acids, hormones, bilirubin, metal ions, metabolites, and numerous drugs. It also contributes to antioxidant capacity and systemic nutritional/inflammatory status.
Typical modulation in cancer: ↓ circulating albumin is commonly associated with advanced disease, systemic inflammation, malnutrition, and poorer prognosis across many cancer types. Higher pretreatment serum albumin is generally associated with improved survival. However, ALB is usually a prognostic biomarker rather than a direct tumor-driving molecular target.
