Skeletal Muscle Quality is Associated with Worse Survival After Pancreatoduodenectomy for Periampullary, Nonpancreatic Cancer.

Background Body compositionmeasures may predict outcomes of cancer surgery. Whereas low musclemass shown on preoperative computed tomography (CT) scans has been associated with worse outcomes after surgery for pancreatic cancer, less consideration has been given to low muscleattenuation, reflecting poor musclequality. Studies relating musclemass and muscleattenuation with outcomes for patients with periampullary, nonpancreatic cancer are lacking.
