Abstract
A 64-year-old man with metastatic castration-resistant prostate cancer presented for prostate-specific membrane antigen (PSMA) PET/CT in preparation for 177 Lu-PSMA radioligand therapy. For precedent BRCA mutation assessment, fine-needle aspiration cytology of 2 PSMA-positive lymph node metastases was conducted. The acquired material was suitable for next-generation sequencing-based gene panel diagnostics and did not show a BRCA1 / 2 mutation, thus PSMA radioligand therapy was initiated. Fine-needle aspiration cytology of lymph node metastases may be a viable option in evaluating further therapeutic alternatives.
