Clinical Analyses Of "Three-Step" Technique In The Diagnosis Of Cervical Diseases

Objective:To discuss the clinic value of "three-step" technique in the screening and treatment of cervical lesions.Methods:In this study,we analyzed the patients with Cervical lesion which were diagnosed with "three-step" technique from January 2007 to December 2007 in gynecological of Qilu Hospitalof Shandong university.All patients were applied "three-step" technique (Cytology-colposcopy-pathology).The first step,we selected the patients whose cytology were positive(We regarded the ASCUS and over the ASCUS as positive cases);The second step was to use colposcopy;The third step was to use biopsy at the many pots under the guidance of colposcopy.The pathology results is the gold standard.The Cytology and biopsy results are for the control of the results.Give the patients with cervical lesion LEEP,after and before treatment the results of the Pathology are contrasted.The patients review TCT after three months and six months of treatment.Results:1.The examined 279 patients with ASCUS or above lesions,ASCUS was 171 cases(61.29%),LSIL was 73(26.16%);HSIL was 34(12.19%);SCC was 1(0.36%);2.The detection of HSIL rate during TCT and colposcopy was 85.00%and 90.00%,and the two methods have a significant difference (P＜0.05).The detection of LSIL rate during TCT and colposcopy was 77.66% and 84.04%,two methods have significant difference(P＜0.05).279 cases with masculine TCT are biopsied under colposcopy and the results:CINⅠis 94 cases,CINⅡis 19 cases,CINⅢis 21 cases,SCC is 3 cases.The results Cytology and biopsy under colposcopy were in line with the rate: LSIL is 79.41%,HSIL is 69.86%;3.158 cases receive the treatment of cervical LEEP,after and before biopsy the pathological specimens are compared,the same result is 108 cases(68.35%) and the different result is 50 cases(31.65%).The existence is to exist between the different diagnosis,and the x~2 test was significant difference(x~2=16.7521, P＜0.001).Conclusions:1.TCT system can improve the detection rate of cervical lesion and early discover cervical lesions.2.Biopsy under the guidance of colposcopy can improve the detection rate of cervical lesion.Give the ASC-US patients colposcopy biopsy can reduce the rate of misdiagnosis. 3.LEEP is an excellent diagnosis and treatment ways to cervical lesion. 4.Three-step technique is a standard program to diagnose,treat and manage the cervical lesion.
