An Investigational Scan (Magnetic Resonance Elastography) in Detecting Treatment Response in Patients With Advanced Liver Cancer

An Investigational Scan (Magnetic Resonance Elastography) in Detecting Treatment Response in Patients With Advanced Liver Cancer

This trial studies how well an investigational scan (magnetic resonance elastography [MRE]) works with standard imaging (magnetic resonance imaging [MRI]) in detecting response to treatment in patients with liver cancer that has spread to other places in the body. Diagnostic procedures, such as MRE with MRI, may make it easier for researchers to see if the treatment for liver cancer is working.

PRIMARY OBJECTIVE: I. To evaluate the ability of magnetic resonance (MR) elastography (MRE) to detect changes in hepatocellular carcinoma (HCC) between baseline and after initial 6 weeks of treatment (change in MRE liver tumor stiffness compared to percent non-viable/necrotic tumor). SECONDARY OBJECTIVES: I. Correlate MRE imaging measurements with patient survival (overall survival and time to tumor progression) over 18 months. II. Correlate MRE measurements with change in tumor size and enhancement on standard of care MR imaging sequences. OUTLINE: Patients undergo standard of care MRI and MRE over 30-90 minutes within 5 days of liver biopsy before receiving any medical treatment for HCC, at 6 weeks after medical treatment for HCC, and then every 12 weeks for up to 24 months.

Advanced Adult Hepatocellular Carcinoma, Stage III Hepatocellular Carcinoma AJCC v8, Stage IIIA Hepatocellular Carcinoma AJCC v8, Stage IIIB Hepatocellular Carcinoma AJCC v8, Stage IV Hepatocellular Carcinoma AJCC v8, Stage IVA Hepatocellular Carcinoma AJCC v8, Stage IVB Hepatocellular Carcinoma AJCC v8

Patients undergo standard of care MRI and MRE over 30-90 minutes within 5 days of liver biopsy before receiving any medical treatment for HCC, at 6 weeks after medical treatment for HCC, and then every 12 weeks for up to 24 months.

Imaging measurements and percent necrosis will be summarized using mean, standard deviation (SD), and range. Pearson correlation coefficient will be estimated between imaging measurements and percent necrosis.

Will be determined by pathologists using follow-up biopsy/surgery samples. Imaging measurements and percent necrosis will be summarized using mean, SD, and range. Pearson correlation coefficient will be estimated between imaging measurements and percent necrosis.

Cox proportional hazard model will be used to correlate imaging measurements with survival endpoints.

Will correlate MRE measurements with change in tumor size and enhancement on standard of care MR imaging sequences. Linear mixed model will be used to correlate MRE imaging measurements with other tumor characteristics (e.g. size, etc.).
