Potential value and advances in research on bone mineral density (BMD) measurement in the auxiliary clinical assessment of hepatocellular carcinoma

Abstract

Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer death worldwide and its prognosis is highly heterogeneous, being related not only to underlying chronic liver disease but also to the severity of cancer cachexia. Nutritional factors play a crucial role in influencing the prognosis of HCC. Despite musculoskeletal imbalance being consistently reported as a predictor of perioperative mortality in patients with HCC, this condition is often overlooked in clinical management. Bone mineral density (BMD), which serves as a marker of nutritional status, can be assessed through CT by measuring the pixel density of the vertebral bone. Recent clinical studies have indicated that BMD serves not only as a significant risk factor for development of HCC in cirrhotic patients but also potentially functions as an independent prognostic indicator for post-treatment outcomes in patients with HCC. Preoperative abdominal CT scans provide a convenient and cost-effective method to measure BMD, offering significant assistance in prognostic evaluation of patients with HCC. A thorough grasp of the liver-bone connection, along with the conduct of higher-quality studies and the establishment of standardized methods and cutoff values for BMD measurement, could enhance approaches to manage HCC.
