Application of visual inspection with acetic acid staining for cervical cancer screening in rural area

Objective To investigate the feasibility of visual inspection with acetic acid staining for cervical cancer screening in rural area.Methods Retrospective analysis was performed on the data of cervical cancer screening collected from 2008 to 2009 in Qingyuan city of Guangdong province.Visual inspection with acetic acid(VIA) staining and iodine(VILI) staining were used generally,while the individuals with abnormal result were further performed colposcopy biopsy and pathologic diagnosis.The suspicious individuals screened out in 2008 were reexamined in 2009.The incidences of various grades of lesion tested by visual inspection screening and by the routine screening in our department were compared.Results The rates of compliance population in 2008 and 2009 were 33.38% and 50.71% respectively.The results from pathologic diagnosis on colposcopy biopsy in 2008 and 2009 were as following:normal cases were 52(86.67%) and 51(70.83%) respectively,cases with CIN I were 5(8.83%) and 11(15.28%) respectively,cases with CIN II were 1(1.67%) and 4(5.56%) respectively,cases with CIN III were 2(3.33%) and 5(6.94%) respectively,cases with cervical cancer were 0 and 1 respectively,and the rates of treatment were 33.33% and 30.00% respectively.The rate of reexamination in 2009 was 12.06%,of which pathologically diagnosed as normal were 2 cases(33.33%),CIN I were 3 cases(50.00%),CIN II was 1 case(16.67%) and none with CIN III.There was no statistical significance between the deference of the rates by visual inspection screening in 2008 and by the routine examination in our department,but the difference of the rates by visual inspection screening in 2009 and by the routine examination in our department was statistical significance(P0.05).Conclusions Visual inspection with acetic acid staining for cervical cancer screening is a cost-effective method in the area where resources is limited and economy is underdeveloped.With propaganda and education of the knowledge on cervical cancer,the compliance of participation and treatment will increase which will make early diagnosis and treatment possible and then the incidence and mortality of cervical cancer will be reduced.
