摘　　要：目的 :检测宫颈癌患者外周血标本中的组织特异性标志物 (CK19mRNA)与宫颈癌相对特异性标志物(HPV16mRNA)的表达。方法 :采用RT PCR技术检测了Ⅰb～Ⅱb期宫颈癌患者的外周血标本 30例 ,远处转移宫颈癌患者 8例 ,妇科良性疾病患者 16例 ,健康人 9例。结果 :30例外周血标本中 3例扩增出CK19的特异性条带 ,检出率为 10 .0 % (3/ 30 )。远处转移患者CK19检出率为 8/ 8,良性病变患者为 0 / 16 ,健康者为 0 / 9。 30例宫颈癌患者中有 10例患者术后宫颈癌标本的免疫组化HPVE6和 (或 )原位杂交为阳性 ,均未检测到HPV16mRNA(0 / 10 ) ;8例远处转移患者的检出率为 12 .5 % (1/ 8) ,妇科良性病变患者和健康者的检出率分别为 0 / 16和 0 / 9。结论 :CK19mRNA作为宫颈癌患者外周血的检测标志物显示了较好的敏感性和特异性。HPV16mRNA的检出率较低 ,临床价值有待进一步研究。Purpose:To detect the expression of cytokeratin 19 (CK19) mRNA and human papillomavirus type 16 (HPV16) mRNA in peripheral blood of cervical cancer patients. Methods:We used reverse transcription polymerase chain reaction (RT-PCR) to determine the expression of CK19 and HPV16 mRNA of 30 cervical cancer patients,8 patients with known distant metastases,16 patients with benign gynecological tumors and 9 healthy persons as control. Results:The presence of CK19 mRNA was observed in 3 peripheral blood samples among 30 cervical cancer patients (10%). The positive ratios for cervical patients with metastases,benign tumors and healthy control were 8/8,0/16 and 0/9. Only 10 cervical samples were proved to be HPV 16 positive by immunohistochemistry and/or hybridization in situ,whose expression of HPV16 mRNA in the peripheral blood were all negative (0/10). The positive ratios for cervical patients with metastasis,benign tumors and healthy control were 1/8,0/16 and 0/9,respectively. Conclusions:CK19 mRNA may be considered a powerful biomarker in the detection of peripheral blood of cervical cancer patients due to its high sensitivity and specificity. The detection of HPV16 mRNA was low and its clinical significance needs further evaluation.
