Alpha-fetoprotein increases by more than 1 μg/L per year

Under normal circumstances, an annual increase of more than 1 μg/L in alpha-fetoprotein (AFP) may be caused by physiological factors, pregnancy, hepatitis, liver cirrhosis, or hepatocellular adenoma. Patients are advised to follow medical guidance for symptomatic treatment. The detailed analysis is as follows:

1. Physiological factors

Alpha-fetoprotein is a glycoprotein primarily synthesized by hepatocytes and the yolk sac. In women, AFP levels may rise slightly, but the increase is generally modest and considered a normal physiological phenomenon that does not require special treatment.

2. Pregnancy

Elevated AFP does not necessarily indicate a health problem. In women, AFP levels naturally rise during pregnancy. This is a normal occurrence, with AFP concentrations in the blood typically peaking between the 7th and 8th months of gestation and gradually returning to normal levels about three weeks after delivery.

3. Hepatitis

Hepatitis refers to inflammation of the liver, commonly caused by infections from bacteria, viruses, or parasites. Liver inflammation can impair liver function, leading to elevated AFP levels. Under a doctor's supervision, patients may take medications such as compound glycyrrhizin tablets or bifendate tablets for treatment.

4. Liver cirrhosis

Liver cirrhosis is usually caused by long-term bile stasis, drug-induced injury, or other factors. Impaired liver function due to cirrhosis can disrupt AFP synthesis, resulting in elevated levels. Patients may be prescribed entecavir tablets or tenofovir alafenamide fumarate tablets under medical guidance.

5. Hepatocellular adenoma

Hepatocellular adenoma is a relatively common benign liver tumor, often caused by congenital factors or long-term oral contraceptive use. The presence of a liver tumor can impair liver function, causing AFP elevation. Treatment may include medications such as sorafenib tosylate tablets or apatinib mesylate tablets under medical supervision. In more severe cases, surgical intervention may be required as directed by a physician.

In addition, primary liver cancer can also cause an annual increase of over 1 μg/L in AFP. If patients experience any discomfort, they should seek timely medical evaluation and receive targeted treatment to avoid disease progression.
