Abstract:
Purpose:To study the expression of CK19 and CK2 0mRNA in peripheral blood patients with FRGO Stage ⅠA to ⅡA cervical carcinoma and to investigate its clinical significance. Methods:Using the reverse transcription polymerase chain reacti on(RT-PCR),CK19 and CK20mRNA expression was examined in peripheral blood fro m 250 patients with early cervical carcinoma before operation,50 Patients with benign gynecological tumors and 18 healthy volunteers. In 250 patients,possible correlations between clinical pathological factors were analyzed. Results:The positive expression rates of CK19 and CK20mRNA were 36% and 24% in 250 cervical carcinomas respectively,in comparison with 3.0% an d 0% with benign gynecological tumors and all subjects in healthy volunteers wer e negative; The expression of CK19 and CK20 mRNA were significantly correlated w ith lymph vascular space involvement,but was not associated with prognostic fac tors including stage,differentiation,pathological types ,lymph node metastasis ,bully tumor size . In patients with CK19 mRNA(+)/CK20 mRNA(+),the rate of lymp h node metastasis and vascular space involvement and recurrence outside the pelv is was significantly higher than that of patients with CK1R mNA9(-)/CK20 mRNA(- )(P
