Evaluating PIVKA-II levels in liver cancer patients with portal vein thrombosis

Prothrombin Induced by Vitamin K Absence II (PIVKA-II) Serum Level as a Predictor for Portal Vein Tumor Thrombosis in Hepatocellular Carcinoma Patients.

Observational Tanta University · NCT06960954

This study is trying to see if measuring a specific protein in the blood can help tell if liver cancer patients have a blockage in their portal vein caused by the tumor.

What this trial studies

This observational study aims to assess the relationship between Prothrombin induced by vitamin K absence II (PIVKA-II) serum levels and the presence of portal vein tumor thrombosis (PVTT) in patients diagnosed with hepatocellular carcinoma (HCC). Researchers will compare PIVKA-II levels in HCC patients who have PVTT against those who do not. Participants will undergo a series of evaluations including clinical examinations, laboratory tests, and imaging studies to determine tumor characteristics and the presence of PVTT. The study seeks to enhance understanding of PIVKA-II as a potential biomarker for PVTT in HCC patients.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 years with confirmed hepatocellular carcinoma, regardless of the presence of portal vein tumor thrombosis.

Not a fit: Patients who have undergone prior locoregional therapy, liver transplantation, or those with other malignancies may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a reliable biomarker for predicting portal vein thrombosis in hepatocellular carcinoma patients, aiding in early diagnosis and treatment.

How similar studies have performed: While the specific approach of using PIVKA-II for this purpose may be novel, similar studies have explored biomarkers in relation to portal vein thrombosis in liver cancer, indicating potential for success.
