Screening and Tumour Markers for Primary Liver Cancer

HCC has a characteristic imaging signature, so biopsy is reserved for genuine diagnostic dilemmas. An arterially enhancing lesion with venous washout on a properly phased triphasic CT is treated as diagnostic in around 95 percent of cases; MRI is used when the CT is inconclusive. Around 40 percent of HCC patients have an elevated AFP, meaning 60 percent do not, so diagnosis relies on radiology rather than tumour markers.

No. Dr. George has operated on perihilar cholangiocarcinoma patients with bilirubin as high as 30 to 35. Surgical practice has also evolved: where extended resections once left only the left lateral section or right posterior sector achievable, his unit now more often does a left- or right-with-caudate resection with extended bile duct resection, preserving more liver parenchyma. Preoperative biliary drainage, usually percutaneous (PTBD) rather than endoscopic nasobiliary drainage, is reserved for patients with cholangitis or those planned for portal vein embolisation.

Alpha-fetoprotein is the marker primarily elevated in hepatocellular carcinoma. CA19-9 comes primarily from the biliary system and can rise somewhat in cirrhotic patients, but not to a high degree, so it remains the more specific marker for cholangiocarcinoma.

After HCC resection on a normal liver, patients are generally placed on lenvatinib long-term. After transplant, there is no separate adjuvant chemotherapy; instead, immunosuppression is adjusted to tacrolimus plus everolimus rather than the standard tacrolimus and mycophenolate, since everolimus is associated with a lower recurrence risk. For cholangiocarcinoma with nodal or vascular invasion, patients are referred to medical oncology for cisplatin or gemcitabine-based adjuvant therapy, usually once they have recovered, six to twelve weeks later, from preoperative jaundice and cholangitis.

No, this is not typical of the Pringle manoeuvre itself. Needing a stent afterwards points to bile duct involvement: a narrowed biliary confluence after a right hepatectomy, a bile leak that progressed to a stricture after a hepaticojejunostomy, or compromised duct vascularity following preoperative radiotherapy. The Pringle manoeuvre alone may raise liver enzymes, but it should not cause obstructive jaundice.

Patients with known cirrhosis should have an ultrasound and an alpha-fetoprotein (AFP) test every six months. This six-month protocol has been shown to improve survival and remains the standard of care for this population.

No. Unlike hepatocellular carcinoma, cholangiocarcinoma has no established population screening programme.

Yes. AFP is elevated in only about 40 percent of HCC patients, meaning 60 percent have a normal level. PIVKA-II is used alongside AFP to raise sensitivity, but it too can be normal in confirmed disease, which is why diagnosis should never rest on tumour markers alone.

No. Ultrasound remains a screening tool rather than a diagnostic one. Because none of the three tumour markers is reliable enough to stand alone, radiology, specifically phased CT or MRI, carries the actual diagnostic work.
