Neuroendocrine neoplasms (NENs) are biologically diverse tumors. This article is a critical review of recent evidence focusing on systemic therapies (through mid-2025). We summarize what is most practice-relevant and where gaps remain. In diagnosis, somatostatin-receptor PET/CT has largely replaced older scintigraphy, and adding FDG PET can flag more aggressive disease. Blood-based tests and selected tissue markers (e.g., MGMT, DAXX/ATRX/ALT) show promise but require cautious interpretation in routine care. In treatment, radioligand therapy (PRRT) is used earlier in appropriate receptor-positive disease; cabozantinib improves progression-free survival after prior therapy; and belzutifan offers a biomarker-guided option for malignant pheochromocytoma/paraganglioma. Immunotherapy remains limited to defined subsets, including high-grade neoplasms. We appraise strengths and limitations of key trials, note issues of access and toxicity, and highlight active areas in development (SSTR antagonists, alpha emitters, and dose-guided PRRT). Our goal is to provide a concise, evidence-based map of the field to support informed clinical judgment and future research priorities.
神经内分泌肿瘤(NENs)是一类生物学特性多样的肿瘤。本文对截至2025年中期的全身性治疗最新证据进行了批判性评述,重点总结最具临床实践价值的内容及现存研究空白。在诊断方面,生长抑素受体PET/CT已基本取代传统闪烁显像技术,联合FDG PET可有效识别更具侵袭性的病变。血液检测及特定组织标志物(如MGMT、DAXX/ATRX/ALT)虽展现应用前景,但在常规诊疗中需审慎解读。治疗领域进展包括:放射性配体疗法(PRRT)在适宜受体阳性患者中应用时机前移;卡博替尼可改善经治患者的无进展生存期;贝组替凡为恶性嗜铬细胞瘤/副神经节瘤提供了生物标志物指导的治疗选择。免疫治疗目前仍限于特定亚群,包括高级别神经内分泌肿瘤。本文评估了关键临床试验的优势与局限,关注治疗可及性与毒性问题,并着重指出当前重点研发方向(SSTR拮抗剂、α粒子疗法及剂量引导的PRRT)。旨在通过简明扼要的循证医学图谱,为临床决策制定与未来研究方向提供参考依据。
