In this real-world dataset, the highest expression of SSTR2 was found in ONB and EBV+ SNUC, suggesting a role for SSTR2-directed strategies.
Additionally, all EBV+ SNUCs were PD-L1+, immunogenic, and predominantly T-cell inflamed suggesting potential for immunotherapeutic strategies. For SNUC, validation of these results in additional cohorts is important.
