3. General categorization of cervical smear results
For cervical cytology tests done among registered women from 2004 to
2008, the proportions of the results categorized according to the Bethesda
System 2001 are shown in Figure 7. In the past five years, over 92% of
smear results were 'Negative for intraepithelial lesion or malignancy',
while around 7% were abnormal. The proportions of negative (91.2%) and
abnormal smears (8.1%) in 2008 were similar to those of 2006 and 2007
but had changed slightly compared with the data of 2004 and 2005 (Figure
8).

4. Abnormal cervical smear results
Up to 31 December 2008, a total of 38 925 abnormal cervical cytology
tests were recorded among the registrants in CSIS from 2004 to 2008. The
commonest abnormalities were atypical squamous cells of undetermined significance
(ASCUS) (64.0%), followed by low-grade squamous intraepithelial lesion
(LSIL) (30.2%) and high-grade squamous intraepithelial lesion (HSIL) (3.7%).
Squamous cell carcinoma and adenocarcinoma were found in 8 and 36 smears
respectively (Figure 9).
The percentage of abnormal cervical smears among the registered women
by age is shown in Figure 10. The highest proportion of epithelial cell
abnormality (8.5%) was found in the age group of below 25, while the 60-64
age group had the lowest proportion of abnormal result (4.3%). The overall
proportion of abnormal smears was 7.1%.
