摘要:
神经内分泌肿瘤(Neuroendocrine neoplasms, NENs)是一种异质性神经内分泌系统肿瘤,其特点是惰性的生长速率和分泌多种肽激素和生物胺的能力。主要发生在消化道系统,且胃肠胰部位更加多见。目前,胃肠胰NENs (Gastroenteropancreatic-NENs, GEP-NENs)已成为消化系统第二类常见的癌症肿瘤。临床常用的CgA、Syn、CD56、NSE及Ki-67和新兴潜在SSTR2、INSM1和CD200的生物标记物的表达在诊断GEP-NENs方面被不断研究,但在疾病的预测、预后等方面仍有缺陷,随着神经内分泌肿瘤类型不断细化,迫切需要更加准确的生物标记物。因此,深入了解上述标记物与疾病的关系不仅对GEP-NENs的预测、诊断、治疗和预后有着深刻意义,而且为这些难治性肿瘤提供潜在治疗靶点。Neuroendocrine neoplasms (NENs) are heterogeneous tumors of the neuroendocrine system characterized by inert growth rates and the ability to secrete multiple peptide hormones and biogenic amines. They occur mainly in the digestive system and are more common in gastroenteropancreatic sites. Currently, gastroenteropancreatic-NENs (GEP-NENs) have become the second most common type of cancerous tumors of the digestive system. The expression of clinically used biomarkers of CgA, Syn, CD56, NSE and Ki-67 and emerging potential SSTR2, INSM1 and CD200 have been continuously investigated in the diagnosis of GEP-NENs. However, they are still defective in the prediction of the disease, prognosis, etc. With the continuous refinement of neuroendocrine tumor types, there is an urgent need to continue with more accurate biomarkers. Therefore, an in-depth understanding of the relationship between the above markers and the disease is not only of profound significance for the prediction, diagnosis, treatment and prognosis of GEP-NENs, but also provides potential therapeutic targets for these refractory tumors.
