However, adding other screening methods to this test may increase the sensitivity and specificity of case finding. Current study has been designed to assess the sensitivity and specificity of the combination of Tru-Screen and Pap tests in comparison to Pap smear alone in women referred for annual screening. Methods: This case-control study was conducted in two groups of 66 and 73 women with epithelial cell abnormality and normal results on Pap smear, respectively. Both groups were subsequently tested with Tru-Screen and colposcopy. Positive finding in any of the three studies made the patient candidate for biopsy as the standard diagnostic test. SPSS software was used to analyze sensitivity, specificity, positive predictive value, and negative predictive value of TruScreen, Pap smear, colposcopy and the combination of TruScreen and Pap tests. Results: 105 out of 139 women underwent biopsy. Of these, 32 (30.5%) had abnormal result in biopsy. Combination of True screen and Pap smear led to a sensitivity of 93.8% and specificity of 79.5% which means an improvement in both parameters. False negative rate decreased to 6.3% but false positive rate increased to 82.2%. Positive and negative predictive values of the combined tests were 33.3% and 86.7%, respectively. Conclusion: Combination of TruScreen and Pap smear is associated with a significant improvement in both sensitivity and specificity for early screening of preneoplastic and neoplastic cervical epithelial lesions.展开更多

Objective: To investigate the prevalence and risk factors of cervical epithelial abnormalities among patients attending a health care specialty center (HCSC) of King Abdulaziz Medical City, Riyadh, KSA. Design: A questionnaire was developed to collect information about socio-demographic variables followed by cytopathological analysis of Papanicolaou (Pap) smear. Settings: Female patients attending the gynecology clinic in the HCSC for cervical abnormalities during 2006 and 2008 were selected for the study. Subjects and Methods: Pap smear was collected and subjected to cytopathological analysis, which was further classified according to the revised Bethesda 2001 system. Information on socio-demographic variables, type and duration of oral contraceptives usage, active or passive smoking, history of sexually transmitted disease, or cervical cancer was collected by trained healthcare professionals. Results were analyzed using chi-square test and t-test. Main outcome measures: Lower frequency of cervical lesions among KSA females in comparison with the western countries. Results: A total of 495 Pap smears were studied, out of which 31 Pap smears were found to be unsatisfactory and therefore excluded. Among the remaining Pap smears, 6.5% were found to be abnormal;however, this was not statistically significant. None of the studied socio-demographic factors were found to be significantly correlated with the appearance of abnormal Pap smears, except for passive smoking. Conclusion: Saudi Arabia had a lower frequency of cervical lesions in comparison with the western countries. Further, this study can serve as a pilot study for a larger national screening program for the identification of prevalence and risk factors of cervical lesions in the women of KSA. Limitations: Cases included in the study belong to the particular period, and patients with abnormal Pap smears were not followed up. In-extension, the included data were not restricted for a particular community.展开更多

In this study, we assessed the triage value of human papillomavirus （HPV） 16/18 genotyping in 273 patients with LSIL/CINI. HPV16/18 genotyping was performed at baseline and follow-up was at 6-monthly intervals for up to 2 years. At each follow-up, women positive for cytology or high-risk HPV （hrHPV） were referred for colposcopy. Enrollment cytology, HPV16/18 genotyping, and questionnaire-obtained factors were linked to the 2-year cumulative progression rate. Univariate and multivariate analyses were performed taking into account time-to-event with Cox proportional hazard regression. The results showed that 190 cases （69.6%） regressed, 37 （13.6%） persisted, and 46 （16.8%） progressed. HPV16/18 positivity （hazard ratio （HR）, 2.708; 95% confidence interval （CI）, 1.432-5.121; P=-0.002） is significantly associated with higher 2-year cumulative progression rate. Sub-analysis by enrollment cytology and age restricted the positive association among patients preceded by mildly abnormal cytology and aged 30 years or older. Immediate treatment is a rational recommendation for the high-risk subgroup, when good compliance is not assured.展开更多

Follow up, to ensure adherence to regular screenings, still poses challenges in poor resource settings. Objective: This study aims at determining the cervical cancer screening uptake, adherence to follow up instructions and interval cervical cancer screening and intervention to improve adherence through personalized reminders (phone calls and text messages). Methods: This was a prospective study of clients screened for cervical cancer at the University of Nigeria Teaching Hospital, Enugu from January 2012 to December 2016. The participants were studied for adherence to interval follow-up screening. Eligible participants were followed up using phone calls and text messages and the outcome noted. The data was analysed using statistical software for social sciences (SPSS) version 17. Results: The mean age and parity of 1146 participants screened for cervical intra-epithelial abnormalities within the study period was 44.18 ± 11.08 years and 3.78 ± 2.08 respectively. Most of the subjects (91.8%) screened negative to squamous intra-epithelial lesion (SIL) or malignancy, 8.2% (94/1146) had various grades of SIL. Thirty-five (37%), 29 (31%), 16 (17%) and 14 (15%) of the 94 SIL positive cases had atypical cells of unknown significance (ASCUS), low-grade squamous intra-epithelial lesion (LGSIL), high-grade squamous intra-epithelial lesion (HGSIL) and cervical carcinoma respectively. Adherence to instructions for repeat cytology was only 37.7% while that for 3 yearly interval rescreening was 17.5%. Phone calls and messages to clients improved adherence to appreciable extent. Conclusion: Adherence to interval and follow-up screening for cervical cancer was low. The use of phone calls and short message services (SMS) to remind clients of screening appointments increased adherence and should be employed in developing countries.展开更多
