简要总结
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.
详细描述
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.

结局指标
主要结局
Change in magnetic resonance elastography (MRE) liver tumor stiffness
时间窗: Baseline to 6 weeks
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.
Change in percent non-viable/necrotic tumor
时间窗: Baseline to 6 weeks
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.
次要结局
- Overall survival(18 months)
- Change in tumor size and enhancement(Baseline to 18 months)
- Time to tumor progression(18 months)
