Nasopharyngeal carcinoma may express somatostatin receptors (SSTR). We present a case with metastatic nasopharyngeal carcinoma in the liver, bone, and lymph nodes. The patient was in progression after chemotherapy, external beam radiation therapy (ERBT), atezolizumab, and cetuximab. Due to strong SSTR expression of the metastases, PRRT was applied. After 3 cycles of intravenous 177Lu-DOTATOC and 1 cycle of intraarterial 90Y-DOTATOC therapy, the hepatic and bone metastases showed excellent response after PRRT. No nephrotoxicity or myelotoxicity was observed.
