摘 要:目的:探讨血清细胞角蛋白19片段( CYFRA21-1)检测在食管癌患者中的临床意义。方法采用ELISA方法分别检测72例食管良性肿瘤和反流性食管炎患者血清CYFRA21-1的浓度及60例食管癌患者术前与术后第7天血清CYFRA21-1的浓度。同时对食管癌患者术后随访3年,监测其血清CYFRA21-1的浓度。结果(1) CYFRA21-1的正常参考值为0~3.30μg/L 时,术前食管癌患者CYFRA21-1阳性率为51.67%(31/60),与对照组[16.67%(12/72)]比较差异有统计学意义(χ2=3.88,P<0.05)。(2)术前Ⅰ、Ⅱ期及Ⅲ、Ⅳ期食管癌患者的CYFRA21-1浓度分别为(3.27±0.33)、(4.88±1.21)μg/L,对照组为(2.24±1.17)μg/L,术前Ⅰ、Ⅱ期及Ⅲ、Ⅳ期食管癌患者的CYFRA21-1浓度高于对照组,差异均有统计学意义( t值分别为2.37、2.00,P均<0.05)。(3)术后第7天,食管癌患者CYFRA21-1浓度为(2.26±1.16)μg/L,与对照组比较差异无统计学意义(t=0.95,P>0.05)。姑息性切除患者CYFRA21-1的浓度为(3.31±0.66)μg/L,与对照组比较差异有统计学意义(t=4.33,P<0.05)。(4)随访3年,影响食管癌生存率的因素有肿瘤病理分期( OR 4.423,95%CI 1.943~4.972,P<0.05)、手术根治性切除与否( OR 0.023,95%CI 0.012~0.036,P<0.05),手术前CYFRA21-1水平( OR 6.798,95%CI 4.328~8.105,P<0.05)、术后CYFRA21-1下降水平(OR 0.117,95%CI 0.074~0.202,P<0.05)。(5)随访期间,吻合口局部复发及远处转移食管癌患者CYFRA21-1浓度为(7.97±0.44)μg/L,与对照组比较差异有统计学意义( t=5.11,P<0.05)。结论 CYFRA21-1对食管癌术前阳性率诊断、术后复发监测、远处转移监测、预后预测具有重要的临床应用价值。Objective To study the clinical significance of the novel tumor marker Cytokerantin-19-fragment( CYFRA 21-1) of peripheral blood in patients with esophageal cancer. Methods The CYFRA 21-1 level in peripheral blood of 72 patients with benign tumor of esophagus or reflux esophagitis and 60 patients with esophageal cancer was examined before and 7 days after operation by enzyme-linked immuno sorbent assay ( ELISA) . At the same time, patients with esophageal cancer were followed up for 3 years, and the level of CYFRA21-1 was examined. Results (1)Before the operation,the level of CYFRA 21-1 was 0-3. 30 μg/L in 51. 67%( 31/60 ) of the patients with esophageal cancer, higher than that of the control group ( 16. 67%(12/72),χ2=3. 88,P〈0. 05). (2)Before the operation,the level of CYFRA21-1 in patients with esophageal cancer,stage Ⅰ,Ⅱ and stage Ⅲ,Ⅳ were (3. 27±0. 33) μg/L and (4. 88±1. 21) μg/L,and of the control group was (2. 24±1. 17) μg/L. The levle of CYFRA21-1 in patients with esophageal cancer,stage Ⅰ,Ⅱ andⅢ,Ⅳ were significantly higher than that of the control group( t=2. 37,2. 00,P〈0. 05) . ( 3) On the 7th day after operation,the level of CYFRA21-1 was (2. 26±1. 16) μg/L,and the difference was not significant compared with the control group(t=0. 95,P〉0. 05). The level of CYFRA21-1 with the palliative resection of esophageal cancer was (3. 31±0. 66) μg/L,and the difference was significant compared with the control group(t=4. 33,P〈0. 05) . ( 4 ) After 3 years of follow-up, the factors affecting the survival rate of esophageal cancer were as following:the pathologic stages of tumor(OR 4. 423,95%CI 1. 943-4. 972,P〈0. 05),types of operation(OR 0. 023,95%CI 0. 012-0. 036,P〈0. 05),the level of CYFRA21-1 before operation(OR 6. 798,95%CI 4. 328-8. 105,P〈0. 05),and the decreased level of CYFRA21-1 after operation(OR 0. 117,95%CI 0. 074-0. 202,P〈0. 05) . ( 5) During the follow-up period,the leve
