AFP-L3 and DCP: the other liver cancer markers | CION Cancer Clinics
AFP-L3 and DCP, also called PIVKA-II, are two blood markers that can add information when doctors watch a liver for primary liver cancer. Neither one diagnoses cancer, and neither replaces an ultrasound or a scan. This page explains what each marker measures, what else can raise it, when a doctor might order it, and how to read the report without being misled. At CION Cancer Clinics, our team goes through your scan, blood test and biopsy reports with you and plans the next step.

The short answer
What are AFP-L3 and DCP, and why was I asked to test them?
AFP-L3 and DCP are two extra blood markers that some doctors add when they are watching a liver for hepatocellular carcinoma (HCC), the cancer that starts in the liver's own cells. They do not diagnose cancer on their own. They add a little more information to an ultrasound or a scan, and they are most useful when the ordinary AFP test is normal or unclear.
This page is about primary liver cancer
These markers are built around HCC. If you have been told the cancer in your liver started somewhere else, such as the bowel or the breast, they are rarely helpful and your team will follow other markers instead. The page on primary and secondary liver cancer explains the difference.
Why anyone looks beyond AFP
AFP is the marker most people know. Its weakness is that many small liver cancers never raise it, and hepatitis flares can raise it without any cancer at all. The page on a normal AFP with liver cancer explains why. AFP-L3 and DCP were developed to fill part of that gap. They fill some of it, not all of it.
No blood marker replaces the six-monthly ultrasound for someone with cirrhosis or hepatitis B.Three markers, three jobs
How is AFP-L3 different from AFP, and what is DCP?
They sound alike on a report. They measure quite different things.
AFP
A protein made by the liver of an unborn baby. Adults make very little of it, but levels can rise with liver cancer, with active hepatitis and with a liver that is healing after damage.
Read more on what AFP measures.AFP-L3
Not a different protein, but one particular form of AFP. Cancer cells tend to attach a slightly different sugar chain to the AFP they make. The laboratory measures how much of your AFP carries that cancer-style pattern, and reports it as a share of the total.
Why that helps
- Hepatitis raises AFP, but mostly the ordinary form
- A high share of AFP-L3 points more towards a tumour
- It means little when total AFP is very low
DCP, also called PIVKA-II
An unfinished form of a clotting protein called prothrombin. A healthy liver uses vitamin K to finish it. Some liver cancers release the unfinished version into the blood, and it can be raised even when AFP is normal.
What else raises it
- Warfarin-type blood thinners, which block vitamin K
- Low vitamin K from poor diet or long antibiotic courses
- Blocked bile flow, which stops vitamin K being absorbed
Why they are used together
Each marker misses different tumours. Read side by side, and with a scan, they catch more than any one of them alone. Some scoring tools combine them with age and sex, which is explained on the page about newer surveillance blood tests.
Not sure whether this applies to you?
Ask an oncologistIn practice
When would a doctor actually order these tests?
A surveillance result that does not add up
The ultrasound is hard to read because of a scarred or fatty liver, or AFP is creeping up without a clear cause. The extra markers help decide how soon a better scan is needed.
A nodule that needs a closer look
A nodule has been found. The main next step is a triple-phase CT or MRI, which CION arranges through diagnostic partners. The markers sit beside that scan. They never replace it.
Before treatment starts
If HCC is confirmed, a raised AFP-L3 or DCP gives a starting value. Some teams use that baseline to help judge how the tumour is behaving and how it responds.
During follow-up
After surgery, ablation or TACE, a marker that was raised before treatment can be watched again. A fall is encouraging. A new rise is a reason for a scan, not a verdict on its own.
On your report
What do the words on an AFP-L3 or PIVKA-II report mean?
- AFP-L3 percent
- The share of your total AFP that carries the cancer-style sugar pattern. The laboratory prints its own reference range beside it.
- PIVKA-II
- Another name for DCP. Some Indian laboratories use only this name.
- Reference range
- The values the laboratory sees in most healthy people. It varies by laboratory and method, so compare results from the same laboratory.
- Above range
- A reason for your doctor to look more closely. It is not a diagnosis.
- Not reported
- Some laboratories do not report AFP-L3 when total AFP is too low to measure it reliably. That is normal practice, not a fault.
- GALAD
- A score that combines sex, age, AFP, AFP-L3 and DCP into one number. It is still being tested and is not standard care in India.

Commonly believed
Do more markers mean a more accurate answer?
"If all three markers are normal, there is no cancer."
Some liver cancers raise none of them. A normal panel lowers the worry a little. It does not clear a nodule that a scan has already shown, and it does not replace the next surveillance ultrasound.
"A high PIVKA-II means the cancer has come back."
Warfarin-type blood thinners, low vitamin K and blocked bile ducts all raise it. Tell your doctor every medicine you take, including blood thinners and antibiotics, before reading anything into the number.
"These newer tests are better, so we should skip the ultrasound."
International liver guidelines still build surveillance around ultrasound, with or without AFP. The newer markers are an add-on that some doctors use. They are not a replacement, and the evidence for them is still growing.
"Testing every marker every month will catch it sooner."
More frequent testing mostly produces more borderline results, more worry and more cost. Your doctor sets the interval to match your risk. Following that plan steadily matters more than testing often.
Being straight with you
What this page cannot tell you
It cannot tell you whether your own result means cancer. A marker value only makes sense beside your scans, your liver function, your medicines and your earlier results. The doctor who ordered the test, or an oncologist reviewing everything together, is the right person to read it.
Availability is uneven
Not every laboratory in India offers AFP-L3, and PIVKA-II is more widely available in larger cities than in district towns. If your doctor wants these tests, ask which laboratory will run them, so later results can be compared fairly. Costs vary and are quoted separately.
Who this does not apply to
If you have no liver disease and no hepatitis B, these markers are not a sensible check-up test. If your liver cancer started elsewhere, such as the bowel, other markers matter more. The page on why tumour markers are not a cancer test explains why random testing causes more harm than good.
If you have a marker report and are not sure what it means, the CION tumour board can review it alongside your scans.Questions we are asked
Common questions about AFP-L3 and DCP
Is PIVKA-II the same as DCP?
Yes. Both names describe the same unfinished clotting protein. DCP stands for des-gamma-carboxy prothrombin, and PIVKA-II is an older name that many Indian laboratories still print. If you are comparing two reports, check that both used the same name and ideally the same laboratory.
My AFP is normal but PIVKA-II is high. Should I worry?
It needs explaining, not panic. First check for a warfarin-type blood thinner, recent antibiotics, poor eating or jaundice, because each can raise it. If none applies and you have liver disease, your doctor will usually ask for a triple-phase CT or MRI to look properly.
Can AFP-L3 be high when total AFP is normal?
It can, though when total AFP is very low many laboratories cannot measure the share reliably and leave it blank. A raised share with a normal total is something your doctor reads together with your scan. It is a reason to look carefully, not proof of a tumour.
Do I need to fast before these tests?
Usually not, but follow the laboratory's own instructions. What matters more is telling them, and your doctor, about any blood thinner, vitamin K injection or antibiotic you have taken recently, because those can change the DCP result.
Will my doctor stop surveillance scans if the markers are normal?
No. Surveillance for people with cirrhosis or hepatitis B is built around regular ultrasound. Normal markers do not change that plan. The page on ultrasound plus AFP explains why the scan stays central.
Are these markers used for bile duct cancer?
Not usually. AFP-L3 and DCP are linked to HCC. Cancers of the bile ducts inside the liver are followed with other markers, mainly CA 19-9, alongside scans and a biopsy. Your team will choose markers to match the type of tumour you have.
Does a falling DCP after treatment mean the cancer is gone?
A fall after surgery, ablation or TACE is encouraging, especially if it was high before. It does not prove that every cancer cell has gone. Follow-up scans are still needed on the schedule your team gives you, whatever the markers show.
Who can look at my reports for me?
Bring your marker reports, scans and liver function tests to a CION oncologist. The tumour board can read them together and tell you whether anything needs doing now. Call the helpline if you are not sure which clinic to visit.
