[摘要] 目的 探討老年喉癌患者血清β2-MG和TNF-α與其臨床分型分期的相關性。方法 對60例正常健康者和50例老年喉癌患者的血清采用放射免疫分析(RIA)測定β2-MG和TNF-α的濃度變化情況。結果 老年性喉癌患者血清β2-MG和TNF-α水平顯著高于正常對照組(P<0.01),術后 2w~1個月血清β2-MG和TNF-α水平明顯低于術前(P<0.01),但仍高于正常對照組。且Ⅰ~Ⅱ期與Ⅲ~Ⅳ期喉癌患者血清β2-MG水平比較,差異有統計學意義,而TNF-α水平比較無統計學意義。結論 血清β2-MG和TNF-α水平能反映喉癌患者的機體免疫狀況以及損傷程度,其含量變化可作為喉癌患者病情變化及預后判斷的一項指標。

[Abstract] ObjectiveTo discuss the relevance of the expression of serum β2-MG and TNF-α with the clinical stages of elderly throat cancer patients. MethodsThe concentration changes of serumβ2-MG and TNF-αwere detected in 60 cases of healthy and 50 cases of laryngeal cancer of elderly patients with using radioimmunoassay(RIA). ResultsThe level of serum β2-MG and TNF-α in age-related throat cancer patients were significantly higher than normal controls(P<0.01),after operation 2 w to one month,serum β2-MG and TNF-α level were significantly lower than pre-operative(P<0.01),but still higher than normal controls. And with Ⅰ~Ⅱ,Ⅲ~Ⅳ period of laryngeal cancer patients serum β2-MG levels,the difference was statistically significant,and TNF-αlevels was not significant. Conclusion β2-MG and TNF-αcan reflect the level of immune status in laryngeal cancer patients,as well as the extent of its injury,the content may be as an indicator of the change of condition and judgement of prognosis in patients with laryngeal cancer.

目前,血清β2-微球蛋白(β2-MG)和腫瘤壞死因子-α(TNF-α)作為機體抗腫瘤的效應分子和蛋白國內外已有廣泛深入的研究,但有關老年喉癌患者的相關報道還很少見。本研究對2000年1月~2008年8月我院50例住院老年喉癌患者的血清β2-MG和TNF-α水平進行檢測,現報道如下。
1 材料與方法
1.1 一般資料
50例喉癌患者(均經證實為喉鱗狀細胞癌,無第二原發腫瘤)設為喉癌組,他們均來自我院2000年1月~2008年8月住院患者,其中男34例,女16例;年齡17~71歲,平均(41.6±4.5)歲。正常對照組60例為本院健康者,男35例,女25例,年齡23~72歲,均未患有其他良惡性腫瘤。
1.2 手術分期
按 UICC(1987)頭頸部腫瘤分期標準[1],屬Ⅰ~Ⅱ期者18例、Ⅲ~Ⅳ期者32例。以上受試者均排除免疫系統疾病和感染性疾病,采血前未經任何治療。
1.3 試驗方法
空腹抽取靜脈血3mL,分離血清1mL后置于-20℃冰箱保存待測。血清CEA和微球蛋白以及腫瘤壞死因子(TNF)含量均采用RIA方法測定,試劑由北京東亞生物技術研究所提供(125I批號為200308,抗體批號為200301)。……
