Abstract

BACKGROUND: The New Bethesda System terminology has opened a series of problems about the atypical squamous cells of undetermined significance and low grade squamous intraepithelial lesion categories, particularly on their follow up.
METHODS
We observe 12300 Pap smear examination, from jan 1995 to Dec 1999, in the Health promotion Center in a university hospital. Subjects were defined a the Health Promotion Center in a university hospital by electrical record and chart review.
RESULTS
We find 48 cases of ASCUS and 33 cases of LSIL. When it is followed up by Pap smear, 34 cases of ASCUS are confirmed normal 19 cases(55.9%), benign cellular change 6 cases(17.6%), ASCUS 5 cases(14.7%), HSIL 4 cases(11.8%) and 27 cases of LSIL are confirmed normal 11 cases(40.7%), benign cellular change 3 cases(11.1%), ASCUS 3 cases(11.1%), LSIL 8 cases(29.6%), HSIL 2 cases(7.4%). 14 cases of ASCUS and 23 cases of LSIL are diagnosed by biopsy. Hostologic results of 14 cases of ASCUS are confirmed cervicitis 10 cases(71.4%), Moderate dysplasia 2 cases(14.3%), carcinoma in sute 2 cases(14.3%) and histologic results of 23 cases of LSIL are confirmed cervicitis 15 cases(65.2%), mild dysplasia 3 cases(13%), moderated dysplasia 3 cases(13%), sever dysplasia 1 cases(4.3%), carcinoma in situ 1 case(4.3%). Pap smear only was used for follow-up at family medicine clinic and 14 cases(29.2%), 4 cases(12.1%) are follow-up loss.
CONCLUSION
After it is diagnosed ASCUS or LSIL Lesion of Pap smear in healthy care visitors, Follw-up loss is high in only follow-up Pap smear examination and follow-up results are presented more we severe lesions. To reduce follow-up loss, aggressive diagnosis and managements may be needed more than Pap smear follow-up examination.
