Summary

The RESOLVE trial, an open-label, single-arm, multi-center study, aims to assess the efficacy and safety of ablative radioembolization using TheraSphere Yttrium-90 microspheres. This trial specifically targets patients diagnosed with hepatocellular carcinoma accompanied by localized portal vein tumor thrombosis (Vp1-Vp3) and who maintain good liver function.

PROCEDURE

Ablative radioembolization

The interventional radiologist utilizes a pre-test with 99mTc-MAA SPECT-CT and cone-beam CT for procedural planning. For tumors confined to a single segment, the treatment area is planned to receive a radiation dose of over 400 Gy using the single-compartment MIRD technique. For tumors extending beyond a single segment, the multi-compartment MIRD technique is used to plan a radiation dose of 700 Gy (± 20%) to the tumor. The upper limit for the estimated lung dose is set at 25 Gy, and the upper limit for the perfused non-tumoral liver dose is 250 Gy. In cases where tumors extending beyond a single segment cannot receive the planned dose of 700 Gy (± 20%) due to limits on lung or normal liver dose, the plan is adjusted to deliver the maximum dose to the tumor within the permissible range for lung and normal liver doses. Radioembolization is typically performed in a single session, and any methods not mentioned here should follow the instructions for use of TheraSphere.
