text: Yo, check it out, I got a story to tell,
  'Bout bile acids, they're implicated, can't you tell?
  In gastrointestinal cancer, they play a role,
  Like cholangiocarcinoma, taking its toll.
  
  Concentrations of bile acids, they may rearrange,
  Affecting the pathogenesis, causing a change.
  So we set out to study, to uncover the facts,
  The bile acid profile in gallbladder bile, that's a wrap.
  
  Patients underwent liver resection, we took a peek,
  Thirty-seven with cholangiocarcinoma, strong and unique.
  Hepatocellular carcinoma, we had five in sight,
  And seven with benign biliary diseases, keeping it tight.
  
  Using high pressure liquid chromatography, we analyzed,
  Conjugated and unconjugated bile acids, we realized.
  CCA patients with low or high bilirubin levels,
  Had higher concentrations, it's something that revels.
  
  Total bile acid and conjugated bile acid, they rose,
  In CCA patients, that's how it goes.
  Cholic and chenodeoxycholic acid, they were high,
  In CCA cases with bilirubin reaching the sky.
  
  Total bile acids and primary bile acid, they correlate,
  With serum cholesterol, bilirubin, and ALP, can't debate.
  And guess what? The carcinoembryonic antigen, no lie,
  It correlates with bile acids, and chenodeoxycholic acid, oh my!
  
  So here's the deal, cancer patients have a different game,
  Bile acid concentrations, not the same.
  Accumulation of certain acids, it's plain to see,
  They may be involved in carcinogenesis, that's the key.
