简要总结
This study aims to evaluate the effectiveness and safety of Holmium-166 (Ho-166) transarterial radioembolization (TARE) for treating patients with locally advanced hepatocellular carcinoma (HCC), a common type of liver cancer. HCC is often linked to conditions like liver cirrhosis and viral hepatitis, with a poor prognosis for advanced stages. TARE involves delivering radioactive particles directly to liver tumors, sparing healthy tissue and providing targeted radiation.
This study will include patients diagnosed with HCC who have received Holmium-166 TARE treatment between January 2010 and December 2024. Researchers will look at patient and tumor characteristics, side effects, how well the treatment works, and survival outcomes. The goal is to determine whether Holmium-166 TARE is a safe and effective treatment option for people with locally advanced HCC.
The findings will help doctors better understand how this therapy can be used to treat liver cancer and whether it can improve survival rates for patients with this challenging disease.
详细描述
This study investigates the use of Holmium-166 (Ho-166) transarterial radioembolization (TARE) as a treatment for patients with locally advanced hepatocellular carcinoma (HCC), a primary liver cancer. The research focuses on evaluating both the safety and effectiveness of this therapeutic approach in patients who have been diagnosed with HCC and treated with Ho-166 TARE between January 2010 and December 2024.
HCC is a highly aggressive cancer that commonly arises in individuals with liver cirrhosis, often due to underlying chronic viral hepatitis or metabolic dysfunction-associated fatty liver disease (MAFLD). As the disease progresses, treatment options become limited, particularly in cases where the cancer has reached advanced stages with symptoms, vascular invasion, or extrahepatic spread. Holmium-166 TARE is an interventional procedure that involves delivering microspheres containing the radioactive isotope Holmium-166 directly to the tumor site via the hepatic artery. This targeted radiation therapy is designed to maximize tumor destruction while minimizing damage to surrounding healthy liver tissue.
The study will retrospectively analyze the medical records of patients who received Ho-166 TARE as part of their treatment plan. This includes examining factors such as patient demographics, tumor characteristics, treatment-related side effects or toxicity, radiologic response to the therapy, progression-free survival (PFS), and overall survival (OS). The primary aim is to assess whether Ho-166 TARE provides a significant benefit in terms of tumor response, survival outcomes, and safety when compared to other treatment modalities.
Pre-treatment planning for Holmium-166 TARE involves a detailed assessment of the liver's blood supply through angiography and the use of cone-beam CT and SPECT/CT scans to guide precise delivery of the radioactive microspheres. The dosage is tailored to each patient, aiming to deliver over 150 Gy to the tumor while keeping the healthy liver dose below critical thresholds.
By focusing on a diverse patient population with locally advanced HCC, this study seeks to provide important data that could help refine treatment strategies for liver cancer. The results may support the broader use of Ho-166 TARE in clinical practice, especially for patients who are not eligible for curative treatments like surgery or liver transplantation.
