ARTICLE HIGHLIGHTS
Research background

Yttrium-90 (Y-90) radioembolization (RE) is an intra-arterial targeted liver therapy for patients with hepatic malignancies. Recent publications demonstrate that Y-90 RE can be performed as a single combined procedure, rather than a staged procedures performed over multiple days.

Research motivation

Given the coronavirus disease 2019 (COVID-19) pandemic, there has been an increased need to mitigate infection risk and logistical challenges. By reducing the number of in-person visits, same day Y-90 RE provides an opportunity to improve patient care for oncology patients during the COVID-19 and beyond. However, existing literature describing same day Y-90 RE predominantly report the use of planar scintigraphy without single photon emission computed tomography/computed tomography (SPECT/CT), which may limit the ability to optimize therapy for patients with more advanced malignancies. This retrospective analysis describes the use of pre- and post-treatment SPECT/CT with personalized dosimetry during the COVID-19 pandemic.

Research objectives

Describe the use of same day Y-90 RE with routine SPECT/CT.

Research methods

A same day procedure was developed, consisting of angiography, imaging, and Y-90 resin particle delivery. Routine SPECT/CT after Tc-99m MAA administration was performed for assessment of arterial supply, personalized dosimetry, and extrahepatic activity. Post-treatment Y-90 bremsstrahlung SPECT/CT was performed for confirmation of particle delivery, by utilization of energy windowing to limit signal from previously administered Tc-99m MAA particles.

Research results

A total of 14 patients underwent same day Y-90 RE with SPECT/CT. Mean lung shunt fraction was 6.13% (range 3.5%-13.1%). Y-90 RE was performed for a single lesion in 7 patients, while the remaining 7 patients had treatment of multifocal lesions. All patients tolerated the procedure well and were discharged the same day.

Research conclusions

Same day Y-90 RE with resin-based microspheres is feasible, and provides an opportunity to mitigate infection risk and logistical challenges associated with the COVID-19 pandemic. Consideration of routine SPECT/CT is recommended, especially among patients with complex malignancies, for the potential to improve outcomes and eligibility of patients to undergo same day Y-90 RE.

Research perspectives

Further studies of long-term patient outcomes and cost-benefit analyses would be useful to validate the utility of same day Y-90 with SPECT/CT.
