ＴＳＧＦ是一种新的多糖链肿瘤标志物 ,与恶性肿瘤血管增殖有关 ,在消化道肿瘤、呼吸道肿瘤及其它系统的一些实体肿瘤中 ,其血液浓度均有升高 ,已有文献报道其具广谱性、敏感性、特异性 ,对肿瘤的诊断有帮助。本文测定头颈部恶性肿瘤患者治疗前后血清ＴＳＧＦ的浓度变化加以说 TSGF is a novel tumor marker of polysaccharide chains, which is associated with the proliferation of malignant tumor vessels. The blood concentrations of TSGF are elevated in digestive tract tumors, respiratory tract tumors, and solid tumors of other systems. It has been widely reported in literature. Spectral, sensitivity, and specificity are helpful in the diagnosis of tumors. This article measures the changes of the concentration of serum TSGF before and after treatment in patients with head and neck cancer.
