Official title

Adaptive Stereotactic Radiotherapy With Superparamagnetic Iron Oxide Nanoparticles (SPION) Cellular Magnetic Resonance Imaging on MR-Linac (MR-L-SPION) for Primary and Metastatic Hepatic Malignancies With Assessment of Treatment Response.

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

There is a high prevalence of hepatic cirrhosis in patients with hepatocellular carcinomas (HCC), or chemotherapy-induced hepatic atrophy or hepatosteatosis in patients with liver metastases associated with high risk of radiation-induced liver disease (RILD) after stereotactic body radiotherapy (SBRT). MRI-SPION radiotherapy planning will facilitate detection and maximize avoidance of residual functionally active hepatic parenchyma from over-the-threshold irradiation thus increasing safety of liver SBRT in patients with pre-existing liver conditions. The investigators have previously demonstrated that liver SBRT with SPECT/CT functional treatment planning utilizing 99mTc sulfur colloid in transplant eligible patients associated with minimal hepatotoxicity and without hastening of advanced hepatic cirrhosis progression while patients await liver transplant. Switching from nuclear medicine to an MR-Linac-SPION based quantitative treatment-planning platform will substantially improve diagnostic accuracy in defining safe volumes of residual functional hepatic parenchyma for liver SBRT planning on MR-Linac.
