Prostate cancer with neuroendocrine differentiation is associated with a poor prognosis, rapid disease progression, and treatment resistance, and constitutes a diagnostic and therapeutic dilemma. We present images of 177Lu-DOTATATE scan and 68Ga-DOTATATE PET/CT scan conducted on a 65-year-old man with prostate cancer with neuroendocrine differentiation, whose disease progressed despite conventional treatment and 177Lu-PSMA radioligand therapy; however, an extraordinary radiographic tumor remission, biochemical response, and improvement of clinical symptoms were observed after the patient underwent 177Lu-DOTATATE peptide receptor radionuclide therapy.
