Summary
We report a rare case where targeted Yttrium-90 radioembolization led to the regression of tumors in untreated liver lobes. This suggests a potential abscopal effect in liver cancer treatment, warranting further investigation into its immune mechanisms.
Area of Science:
- Oncology
- Radiotherapy
- Immunology
Background:
- Squamous cell carcinoma can metastasize to the liver.
- Radioembolization is a locoregional therapy for liver tumors.
- The abscopal effect is a rare phenomenon where targeted radiation induces regression of distant, non-targeted tumors.
