血清可溶性Apo-1/Fas水平对监测胃癌生物学行为和预后的临床价值

背景与目的:国内外研究检测发现一些恶性肿瘤血清可溶性Apo-1/Fas(sApo-1/Fas)水平明显高于正常人,但有关化疗对血清sApo-1/Fas影响的研究不多;本课题通过检测胃癌患者血清sApo-1/Fas水平及化疗对血清sApo-1/Fas影响的研究,探讨其临床价值。方法:采用酶联免疫吸附试验(ELISA)检测42例胃癌患者化疗前后血清sApo-1/Fas水平,并与30例正常人作对比分析。结果:胃癌患者血清sApo-1/Fas水平明显高于正常对照组(P<0.01),血清sApo-1/Fas水平与临床分期、细胞分化程度有关,与患者性别、年龄无关。Ⅳ期胃癌患者血清sApo-1/Fas水平明显高于Ⅲ期和Ⅱ期(P<0.05～0.01),Ⅲ期明显高于Ⅱ期(P<0.05)。中、高分化胃癌患者血清sApo-1/Fas水平低于低分化胃癌患者(P<0.05～0.01),化疗后有效(完全缓解和部分缓解)患者血清sApo-1/Fas水平明显低于化疗前(P<0.01)。结论:血清sApo-1/Fas与胃癌的发生、发展相关,可作为胃癌生物学行为和预后的标记物。sApo-1/Fas有可能成为胃癌治疗的新靶点。

Clinical value of serum soluble Apo-1/Fas for predicting biological behaviors and prognosis of gastric carcinoma

BACKGROUND & OBJECTIVE: Literatures reported that the soluble Apo-1/Fas(sApo-1/Fas) levels in serum of patients with malignant carcinoma were higher than that in normal control subject, but there were fewer studies was seldom to detect the level of sApo-1/Fas in patients with malignancy carcinoma and effect of chemotherapy; the subject is to detect the level of sApo-1/Fas in patients with gastric carcinoma and effect of chemotherapy on it, and to investigate its clinical value. METHODS: Enzyme linked immunosorbent assays(ELISA) was available to detect the level of sApo-1/Fas in 42 case of patients with gastric carcinoma before and after chemotherapy, as compared with 30 case of normal control subject. RESULTS: Levels of sApo-1/Fas were elevated in all subgroups of patients with gastric carcinoma as compared to the controls (P < 0.01), sApo-1/Fas was correlated with clinical stage and histological grade, and not with sex, age; the sApo-1/Fas level in stage IV was higher in comparison with stage III and II (P < 0.05-0.01), and in stage III it was higher than in stage II (P < 0.05); being lower in the well differentiated and moderately differentiated than the poorly differentiated(P < 0.05-0.01), that the sApo-1/Fas levels were remarkably reduced in complete remission or partial remission patients(P < 0.01) after chemotherapy. CONCLUSION: sApo-1/Fas may play closely reflect growth and regulation in gastric carcinoma, it may be a predictor for biological behaviors and prognosis of gastric carcinoma; sApo-1/Fas may be a new target in treating gastric carcinoma.
