TuM2-PK检测在消化道肿瘤中的应用价值

Application Value of TuM2-PK Detection in Gastrointestinal Tumors

食管、胃、结直肠等部位的肿瘤总称为消化道肿瘤,由于早期消化道肿瘤患者没有明显的临床症状,从而导致就诊时基本都是肿瘤的中晚期,因此治疗效果差,预后欠佳。大量的研究和临床数据证实,预防和降低死亡率最有效的办法就是早诊断、早治疗。肿瘤的发生、发展与肿瘤标记物的表达水平在一定程度上显示相关性,因此,寻找可用于早期诊断和预后判断的肿瘤标志物一直是人们关注的焦点。M2型丙酮酸激酶(pyruvate kinase isoenzyme type M2, PKM2)是糖酵解过程中的限速酶丙酮酸激酶的同分异构体中的一种,可通过瓦伯格效果促进肿瘤细胞的生长与增值,是肿瘤能量代谢的重要标志,是一种潜在的新型肿瘤标记物,作者对其进行了综述和梳理。

Tumors of the esophagus, stomach, colorectum and other parts are collectively called gastrointesti-nal tumors, because patients with early gastrointestinal tumors have no obvious clinical symptoms, resulting in the middle and advanced stages of the tumor at the time of treatment, so the treatment effect is poor and the prognosis is poor. A large number of studies and clinical data confirm that the most effective way to prevent and reduce mortality is early diagnosis and early treatment. The oc-currence and development of tumors and the expression level of tumor markers show a correlation to a certain extent, so the search for tumor markers that can be used for early diagnosis and prog-nosis judgment has always been the focus of attention. M2 type pyruvate kinase isoenzyme type M2 (PKM2) is an isomer of the rate-limiting enzyme pyruvate kinase during glycolysis, which can pro-mote the growth and appreciation of tumor cells through the waberg effect, is an important marker of tumor energy metabolism, and is a potential new tumor marker. The authors reviewed it and combed the tumor.
