[Clinical Practice of 177Lu-DOTATATE in the Treatment of Neuroendocrine Tumors].

Most of the neuroendocrine tumors(NETs) overexpress the somatostatin receptor(SSTR),which provides a reliable target for SSTR-targeted peptide receptor radionuclide therapy(PRRT).Compared with drug therapy,PRRT has high objective response rate and significantly prolongs patients' survival.Moreover,the patients have good tolerance to this therapy.Considering that PRRT is in clinical trial phase in China,this article elaborates on the selection and preparation of patients,pre-treatment medications,administration methods,treatment cycles,side effects,follow-up plan,and the combination of PRRT with other drugs based on the published international guidelines in this field and our experience from clinical practice.Hoping that relevant professionals can well understand the principle of PRRT and apply it in clinical practice,we write this article to provide a basis for serving real-world patients and carrying out clinical trials.
