Brief Summary

Liver failure is one of the most severe complications in patients undergoing liver surgery for hepatic malignancies. However, it can be predicted through preoperative assessment of liver function. Technetium-99m galactosyl human serum albumin (\[99mTc\] Tc-GSA), combined with single-photon emission computed tomography fused with computed tomography (\[99mTc\] Tc-GSA SPECT/CT), is widely used in Asia due to its superiority in predicting postoperative liver failure. Unfortunately, its clinical use in Western countries remains limited due to concerns about disease transmission. In 2022, the Department of Clinical Physiology and Nuclear Medicine at Rigshospitalet optimized the in-house production of \[99mTc\] Tc-GSA under European regulations, and in April 2025, received approval from the Danish Medicines Agency for its clinical use. This study aims to evaluate, for the first time, the diagnostic accuracy of \[99mTc\] Tc-GSA SPECT/CT in quantifying liver function in European patients with hepatic tumors. Hypothesis: \[99mTc\] Tc-GSA SPECT/CT is capable of and superior to indocyanine green clearance test (ICG), Child-Pug score, Model for End-Stage Liver Disease (MELD) score, and ultrasound elastography in quantifying liver function and predicting surgical outcomes in a Danish cohort of patients with liver tumors. Perceived quality of life may be associated with postoperative complications. However, postoperative complications and survival can be more accurately predicted when quality of life is assessed in combination with preoperative liver function and clinical conditions. Objectives Primary objectives:

  1. 1.To evaluate the correlation between \[99mTc\] Tc-GSA SPECT/CT and established liver function assessments, including ICG clearance, Child-Pugh score, MELD score, and ultrasound elastography.
  2. 2.To compare the discriminative ability of \[99mTc\] Tc-GSA SPECT/CT with existing liver function tests in predicting postoperative complications.
  3. 3.To assess the correlation of \[99mTc\] Tc-GSA SPECT/CT, ICG clearance, Child-Pugh score, MELD score, and ultrasound elastography with postoperative outcomes.
  4. 4.To develop and internally validate a multivariable predictive model combining the best predictive liver function test with preoperative clinical characteristics to predict postoperative complications.

Outcome Measures

Primary Outcomes (5)

  • Correlation between [99mTc] Tc-GSA SPECT/CT parameters and ICG clearance

    The correlation between quantitative liver uptake parameters derived from \[99mTc\] Tc-GSA SPECT/CT and indocyanine green (ICG) clearance will be assessed using Pearson's/Spearman's rank correlation coefficient. \[99mTc\] Tc-GSA SPECT/CT units: Liver function test expresed in Uptake Index (UI) and percentage of total liver volume (FLR%). Indocyanine green (ICG) clearance units: Liver function test reported as: 1.- ICG retention ratio after 15 min (ICGR15), unit: percentage (%) 2.- Rate constant (k) of ICG indicator-dilution curve (KICG), unit: min-1 3.- Plasma dis-appearance rate of ICG (PDRICG), unit: % min-1.

    Once before receiving the planned treatment for a hepatic tumor.

  • Correlation between [99mTc] Tc-GSA SPECT/CT parameters and Child-Pugh score

    The correlation between quantitative \[99mTc\] Tc-GSA SPECT/CT-derived liver function parameters and Child-Pugh score will be assessed using Pearson's/Spearman's rank correlation coefficient. \[99mTc\] Tc-GSA SPECT/CT units: Uptake Index (UI) and percentage of total liver volume (FLR%). Child-Pug score description and units: : Scoring system that estimates cirrhosis severity. It classifies patients into three categories: A - good hepatic function, B - moderately impaired hepatic function, and C - advanced hepatic dysfunction.

    Once before receiving the planned treatment for a hepatic tumor.

  • Correlation between [99mTc] Tc-GSA SPECT/CT parameters and the Model for End-Stage Liver Disease (MELD) score

    he correlation between quantitative \[99mTc\] Tc-GSA SPECT/CT-derived liver function parameters and MELD score will be assessed using Pearson's/Spearman's rank correlation coefficient. \[99mTc\] Tc-GSA SPECT/CT units: Uptake Index (UI) and percentage of total liver volume (FLR%). MELD score definition and units: The Model for End-Stage Liver Disease (MELD) is a prognostic score to measure the severity of liver failure. The MELD score is based on results from five blood tests: Bilirubin, Creatinine, Internal normalized ratio (INR), Serum sodium, and Albumin. The MELD score ranges from 6 to 40, and quantifies end-stage liver disease for transplant planning. The higher the score, the more severe the disease.

    Once before receiving the planned treatment for a hepatic tumor.

  • Correlation between [99mTc] Tc-GSA SPECT/CT parameters and liver stiffness measured by ultrasound elastography

    The correlation between quantitative \[99mTc\] Tc-GSA SPECT/CT-derived liver function parameters and liver stiffness measured by ultrasound elastography will be assessed using Pearson's/Spearman's rank correlation coefficient. 99mTc\] Tc-GSA SPECT/CT units: Uptake Index (UI) and percentage of total liver volume (FLR%) Ultrasound elastography: kilopascals (kPa)

    Once before receiving the planned treatment for a hepatic tumor.

  • Discriminative ability of [99mTc] Tc-GSA SPECT/CT compared with standard liver function tests to predict major postoperative complications

    The discriminative ability of \[99mTc\]Tc-GSA SPECT/CT to predict major postoperative complications (Clavien-Dindo grade ≥ III) will be compared with standard liver function tests, including ICG clearance, Child-Pugh score, MELD score, and ultrasound elastography (units and definitions have been previously described). The Clavien-Dindo classification ranks the severity of surgical complications and consists of seven grades (I, II, IIIa, IIIb, IVa, IVb, and V). Complications of grade ≥ III will be considered major. Discriminative performance will be assessed using the area under the receiver operating characteristic curve (AUC) for each test. AUCs will be compared using DeLong's test.

    Once after the completion of 90-day follow-up.

    Once during the final analysis after completion of 90-day follow-up.

  • Association of [99mTc] Tc-GSA, ICG, Child-Pugh, MELD, and ultrasound elastography with length of stay.

    Once during the final analysis after completion of 90-day follow-up.

  • Association of [99mTc] Tc-GSA, ICG, Child-Pugh, MELD, and ultrasound elastography with readmission.

    Once during the final analysis after completion of 90-day follow-up.

Model Details: The aim of this study is to evaluate the diagnostic accuracy of \[99mTc\] Tc-GSA SPECT/CT in quantifying liver function in European patients with hepatic tumors.

The compassionate permit allows the use of \[99mTc\] Tc-GSA for preoperative evaluation of regional liver function in the part of the liver that is preserved after liver resection due to malignant liver disease (primary liver cancer, primary biliary cancer and colorectal liver metastases). This study will explore the benefits of using \[99mTc\] Tc-GSA in combination with SPECT/CT in patients with a confirmed or suspected diagnosis of hepatic tumor (benign ot malignant) and a planned local treatment (resection and/or ablation).
