Brief summary

This pilot trial studies how well single photon emission computed tomography (SPECT)/computed tomography (CT) with technetium Tc-99m sulfur colloid works in measuring liver function in patients with liver cancer that has or has not spread to other place in the body who are undergoing radiation therapy or surgery. Diagnostic procedures, such as sulfur colloid SPECT/CT scans, may measure normal liver tissue before, during and after treatment and help doctors plan better treatment for liver cancer patients.

Detailed description

OUTLINE: Patients are assigned to 1 of 2 cohorts depending on which standard of care they are receiving outside of this study, as part of their cancer treatment: radiation treatment (RT) or surgery. All patients have a total of 3 SPECT/CT imaging with 99mTc-SC. The first scan in both cohorts is routine medical care (not experimental) and takes place prior to initiation of RT or surgery. Two follow up scans are part of the protocol. COHORT A (patients receiving radiation therapy per standard cancer treatment): The first follow up scan occurs at mid-RT, and the second one at 1 month post-RT. COHORT B (patients undergoing surgery per standard cancer treatment): The first follow-up scan occurs 3-5 days postoperatively, and the second one at 1 month post-operatively. An additional intravenous (IV) contrast enhanced CT scan (70 second delay) will be obtained immediately following the SPECT/CT scan for all 3 SPECT/CT scans. After completion of study, patients are followed up at 6 months.

MeasureTime frameDescription
Longitudinal Changes in Liver Function as Measured by SC SPECT/CT Functional Liver Volume: Cohort A - RadiationBaseline, mid-treatment at 2 weeks, and post-treatment at 1 monthFunctional liver volume ratio (FLV): represents the percent of the anatomic liver which is functioning and is defined as the ratio of liver functional volume (in cc of volume) to the anatomic liver volume (in cc of volume). Since this outcome measure is a ratio, it is unitless. A higher FLV ratio reflects a higher volume of functional liver.
Longitudinal Changes in Liver Function as Measured by SC SPECT/CT Liver-to-Spleen Mean: Cohort A - RadiationBaseline, mid-treatment at 2 weeks, and post-treatment at 1 monthLiver-to-spleen ratio (L/S mean): represents the magnitude of the global liver function and is defined as the ratio of the mean SC counts in the functional liver to the mean SC counts in the spleen. Since this outcome measure is a ratio, it is unitless. A higher L/S mean ratio reflects higher magnitude of liver function.
Longitudinal Changes in Liver Function as Measured by SC SPECT/CT Total Liver Function: Cohort A - RadiationBaseline, mid-treatment at 2 weeks, and post-treatment at 1 monthTotal liver function (TLF): represents the integral liver function and is defined by the product of the functional liver volume (FLV) ratio and liver-to-spleen (L/S) mean ratio. Since this outcome measure is a product of ratios, it is unitless. A higher TLF ratio reflects higher liver function. Median differences were estimated using Wilcoxon (Mann-Whitney) tests.
Longitudinal Changes in Liver Function as Measured by SC SPECT/CT Spatial Heterogeneity: Cohort A - RadiationBaseline, mid-treatment at 2 weeks, and post-treatment at 1 monthTo characterize spatial distribution of functional liver, the coefficient of variation (CV) within the FLV will be measured (unitless). A higher CV means more variability or heterogeneity in liver function.
