A Multicenter, Open-label, Single-arm Study of the Safety and Antitumoral Efficacy of Nivolumab After SIRT Using SIR-Spheres for the Treatment of Patients With HepatoCellular Carcinoma That Are Candidates for Locoregional Therapies

The purpose of this study is to evaluate the effect of the anti-programmed death 1 (PD-1) agent nivolumab following selective internal radiation therapy (SIRT) for patients with unresectable hepatocellular carcinoma (HCC).
SIRT using yttrium90-loaded microspheres is increasingly used to treat patients with HCC, particularly those that are not good candidates for transarterial chemoembolization or TACE. SIRT induces disease control (objective tumor remission or stabilization) in most patients while progression usually results from the growth of new lesions. SIR-Spheres are resin-made microspheres used for SIRT.
On the other hand, nivolumab is under clinical development for the treatment of more advanced HCC. Available data in patients that mostly had progression to other therapies and vascular involvement or metastatic disease show significant systemic antitumor activity that results in durable objective remissions and disease stabilizations.
Therefore, in patients with HCC that has not spread beyond the liver, the systemic action of nivolumab may improve the anti-tumor effect of SIRT. Furthermore, by inducing immunogenic tumor cell death, SIRT may have a synergistic effect with nivolumab.

Feasibility of Liver Transplantation after 90Y Radioembolization: Lessons from a Radiation Protection Incident

Article

Author: Lussey-Lepoutre, Charlotte ; Savier, Eric ; Roux, Charles ; Allaire, Manon ; Maisonobe, Jacques-Antoine ; Maksud, Philippe ; Soret, Marine ; Kas, Aurélie ; Payen, Stéphane

Abstract:

Radioembolization using 90Y is a growing procedure in nuclear medicine for treating hepatocellular carcinoma. Current guidelines suggest postponing liver transplantation or surgical resection for a period of 14 to 30 d after radioembolization to minimize surgeons’ exposure to ionizing radiation. In light of a radiation protection incident, we reevaluated the minimum delay required between radioembolization and subsequent liver transplantation. A patient with a hepatocellular carcinoma underwent a liver transplantation 44 h after undergoing radioembolization using 90Y (860 MBq SIR-Spheres). No specific radioprotection measures were followed during surgery and pathological analysis. We subsequently (1) evaluated the healthcare professionals' exposure to ionizing radiation by conducting dose rate measurements from removed liver tissue and (2) extrapolated the recommended interval to be observed between radioembolization and surgery/transplantation to ensure compliance with the radiation dose limits for worker safety. The surgeons involved in the transplantation procedure experienced the highest radiation exposure, with whole-body doses of 2.4 mSv and extremity doses of 24 mSv. The recommended delay between radioembolization and liver transplantation was 8 d when using SIR-Spheres and 15 d when injecting TheraSphere. This delay can be reduced further when considering the specific 90Y activity administered during radioembolization. This dosimetric study suggests the feasibility of shortening the delay for liver transplantation/surgery after radioembolization from the 8th or 15th day after using SIR-Spheres or TheraSphere, respectively. This delay can be decreased further when adjusted to the administrated activity while upholding radiation protection standards for healthcare professionals.

MIDOS: a novel stochastic model towards a treatment planning system for microsphere dosimetry in liver tumors

Article

Author: Dawson, Robert J ; Wehrenberg-Klee, Eric ; Paganetti, Harald ; Bolch, Wesley E ; Bertolet, Alejandro ; Beekman, Chris ; Withrow, Julia D ; Huesa-Berral, Carlos

PURPOSE:

Transarterial radioembolization (TARE) procedures treat liver tumors by injecting radioactive microspheres into the hepatic artery. Currently, there is a critical need to optimize TARE towards a personalized dosimetry approach. To this aim, we present a novel microsphere dosimetry (MIDOS) stochastic model to estimate the activity delivered to the tumor(s), normal liver, and lung.

METHODS:

MIDOS incorporates adult male/female liver computational phantoms with the hepatic arterial, hepatic portal venous, and hepatic venous vascular trees. Tumors can be placed in both models at user discretion. The perfusion of microspheres follows cluster patterns, and a Markov chain approach was applied to microsphere navigation, with the terminal location of microspheres determined to be in either normal hepatic parenchyma, hepatic tumor, or lung. A tumor uptake model was implemented to determine if microspheres get lodged in the tumor, and a probability was included in determining the shunt of microspheres to the lung. A sensitivity analysis of the model parameters was performed, and radiation segmentectomy/lobectomy procedures were simulated over a wide range of activity perfused. Then, the impact of using different microspheres, i.e., SIR-Sphere®, TheraSphere®, and QuiremSphere®, on the tumor-to-normal ratio (TNR), lung shunt fraction (LSF), and mean absorbed dose was analyzed.

RESULTS:

Highly vascularized tumors translated into increased TNR. Treatment results (TNR and LSF) were significantly more variable for microspheres with high particle load. In our scenarios with 1.5 GBq perfusion, TNR was maximum for TheraSphere® at calibration time in segmentectomy/lobar technique, for SIR-Sphere® at 1-3 days post-calibration, and regarding QuiremSphere® at 3 days post-calibration.

CONCLUSION:

This novel approach is a decisive step towards developing a personalized dosimetry framework for TARE. MIDOS assists in making clinical decisions in TARE treatment planning by assessing various delivery parameters and simulating different tumor uptakes. MIDOS offers evaluation of treatment outcomes, such as TNR and LSF, and quantitative scenario-specific decisions.

Predictive Factors for Adverse Event Outcomes After Transarterial Radioembolization with Yttrium-90 Resin Microspheres in Europe: Results from the Prospective Observational CIRT Study.

Article

BACKGROUND:

Using data collected in the prospective observational study CIRSE Registry for SIR-Spheres Therapy, the present study aimed at identifying predictors of adverse events (AEs) following transarterial radioembolization (TARE) with Yttrium-90 resin microspheres for liver tumours.

METHODS:

We analysed 1027 patients enrolled between January 2015 and December 2017 and followed up for 24 months. Four hundred and twenty-two patients with hepatocellular carcinoma (HCC), 120 with intrahepatic carcinoma (ICC), 237 with colorectal liver metastases and 248 with liver metastases from other primaries were included. Prognostic factors were calculated with a univariable analysis by using the overall AEs burden score (AEBS).

RESULTS:

All-cause AEs were reported in 401/1027 (39.1%) patients, with AEs associated with TARE, such as abdominal pain (16.6%), fatigue (17%), and nausea (11.7%) reported most frequently. Grade 3 or higher AEs were reported in 92/1027 (9%) patients. Reports on grade ≥ 3 gastrointestinal ulcerations (0.4%), gastritis (0.3%), radiation cholecystitis (0.2%) or radioembolization-induced liver disease (0.5%) were uncommon. Univariable analysis showed that in HCC, AEBS increased for Eastern Cooperative Oncology Group (ECOG) 0 (p = 0.0045), 1 tumour nodule (0.0081), > 1 TARE treatment (p = 0.0224), no prophylactic embolization (p = 0.0211), partition model dosimetry (p = 0.0007) and unilobar treatment target (0.0032). For ICC, > 1 TARE treatment was associated with an increase in AEBS (p = 0.0224), and for colorectal liver metastases, ECOG 0 (p = 0.0188), > 2 prior systemic treatments (p = 0.0127), and 1 tumour nodule (p = 0.0155) were associated with an increased AEBS.

CONCLUSION:

Our study confirms that TARE is a safe treatment with low toxicity and a minimal impact on quality of life.
