Current Practices in B7-H3 Testing

Author(s)Joshua K. Sabari, MD

Joshua K. Sabari, MD, discusses whether individual B7-H3 analysis is available at his institution, noting that, if it is, he obtains IHC for both PD-L1 and B7-H3 expression levels in all patients with SCLC. If B7-H3 testing becomes available, he would consider adding it to the biomarker assay, particularly at the time of diagnosis or recurrence.
