Aim: A study to assess the role of visual inspection with acetic acid VIA as an alternative to Pap smear in screening program for cervical cancer in low resource settings. Method: Two hundred and twenty five women in reproductive age group attending the Gynecology department at K.S Hegde Charitable Hospital were enrolled in the study. A Papanicolaou smear and visual inspection of the cervix with acetic acid was done. All women then underwent colposcopy using the video colposcope. All patients who tested positive on screening then underwent colposcopy guided biopsy. Pap smear of Low grade squamous intraepithelial lesion (LSIL) and above was taken as abnormal. The statistical test used was chi square test and results were computed using Statistical Package for the Social Sciences (SPSS) version 12.0. Results: Out of 225 patients, VIA was positive in 27(12%) patients and Pap smear was abnormal in 26(11.7%). There were 15 LSIL, 6 high Grade Squamous intraepithelial lesions (HSIL) and 5 were squamous cell carcinoma. On biopsy, there were 15 mild dysplasia, 2 moderate dysplasia, 4 severe dysplasia and 3 squamous cancers. Pap smear had a sensitivity of 83%, specificity of 98%, and positive predictive value of 80 % and negative predictive value of 97.9%. VIA had a sensitivity of 70.8%, specificity of 95%, and positive predictive value of 62.9 % and negative predictive value of 96.5%. Conclusion: Since diagnostic values of VIA is comparable to Pap smear, and it performs well in detecting high grade lesion we conclude that VIA can be used as a screening modality for cervical cancer in low resource settings.

Background: Cervical Cancer is the second most common cancer in women worldwide and India alone contribute the 1/4th of the world’s cases of cervical cancer. In view to this huge burden there was need to establish a feasible screening programme to detect cervical carcinoma at earliest in developing country.Methods: This is a prospective study of 500 women who fulfil the selection criteria. 50 pregnant patients for VIA (Visual inspection with acetic acid), 50 pregnant patients for VILI (Visual inspection with lugol’s iodine) and 400 non-pregnant women for VIA, VILI and colposcopy were enrolled. In positive cases, cervical biopsy with histopathological examination was done. The sensitivity, specificity and positive predictive value of each test were obtained and compared. Chi-square (X2) test was used to test the significance of difference between two proportions of a quantitative data.Results: The sensitivity, specificity, positive predictive value and negative predictive value for VIA (85.1%, 84.1%, 41.7%, 97%), VILI (95.7%, 92.4%, 62.5%, 93.4%) and Colposcopy (83%, 86%, 51.3%, 96.6%) were statistically significant with its histopathological report.Conclusions: In a poor developing country like India where pap smear and colposcopy is not available in low resource setting VIA and VILI can prove a very helpful tool in picking up abnormal looking cervix which can then be confirmed by pap or colposcopy. It will go a long way in reducing the incidence of cervical carcinoma.

Background: Cervical cancer is one of the commonest malignancies and a leading cause of morbidity and mortality among women. The aim of this study was to evaluate the diagnostic value of Papanicolaou (PAP) smear and visual inspection with acetic acid as methods of cervical cancer screening.Materials and Methods: This was a observational cross-sectional study conducted from the period of 2068.11.01 to 2069.11.01. The study population consisted of women with histologically confirmed cervical intraepithelial neoplasia or invasive carcinoma who had undergone prior PAP smear.Results: During the study period 160 patients underwent both PAP smear and cervical biopsy. Of these patients, 49 had a histological diagnosis of cervical intraepithelial neoplasia or invasive carcinoma. The histopathological and cytological diagnoses were compared. Visual inspection with acetic acid status was available for 31 of the 49 cases. The sensitivity of PAP smear was 61%, specificity 97%, positive predictive value 91%, negative predictive value 85% and diagnostic accuracy 86% for detection of cervical neoplasia. Visual inspection with acetic acid had a sensitivity of 74%, specificity 48%, Positive predictive value 64%, Negative predictive value 60% and diagnostic accuracy of 63%. Combining the two procedures increased sensitivity by 26%, Negative predictive value by 11%  and diagnostic accuracy by 2 per cent.Conclusion: PAP smear has a higher specificity, Positive predictive value, Negative predictive value and diagnostic accuracy but lower sensitivity than visual inspection with acetic acid. Visual inspection with acetic acid by itself is not an effective screening method. A combination of PAP smear and visual inspection with acetic acidcan ensure adequate screening of cervical neoplasia.

Objective: Cervical cancer is potentially preventable but still remains a leading cause of cancer mortality in in developing countries like Nigeria. Cytology-based screening programmes are difficult to maintain in these countries. Developing a cheap and reliable alternative is an important public health measure in these regions. This study was carried out to compare the utility of VIA and Pap smear as Cervical cancer screening methods in HIV-infected and non HIV-infected women. Methodology: Between March, 2013 and March, 2014, 461 consenting women, comprising 231 HIV positive women (HPW) and 230 HIV negative women (HNW) were recruited and screened for cervical cancer using conventional Pap smear and VIA simultaneously in University of Uyo Teaching Hospital. The Pap smear findings were classified using the 2001 Bethesda system. Patients with a positive Pap smear or abnormal VIA findings were recalled for biopsy. The results of the two tests were compared using biopsy as the gold standard. Results: The overall sensitivity, specificity, positive predictive value and negative predictive value for VIA were 100%,80%,76.9%, and 100%, respectively compared to 80%, 100%, 100%, and 88.2% for conventional Pap smear. Visual inspection of the cervix with acetic acid for cervical cancer screening is not specific but has a high negative predictive value. Conclusion: This study does not support a “see-and-treat” approach in cervical cancer management using VIA only. In resource-challenged areas, VIA can be applied on a large scale basis in primary screening for cervical cancer so as to triage, women who will benefit from further evaluation before applying the appropriate treatment.

Objectives:To compare the sensitivity, specificity, positive and negative predictive values, and accuracy of Papanicolaou test with visual inspection with acetic acid (VIA)/VIA using magnification devices (VIAM) and develop the best strategy for screening in low resource settings.Materials and Methods:This is a prospective cross-sectional study on 408 symptomatic multiparous women in the reproductive age group, sequentially using the Papanicolaou test, the VIA, and the VIAM for screening. Women with a positive screening test underwent guided biopsy and endocervical curettage. The site of biopsy was recorded. Histopathological findings were taken as the "gold" standard in comparing the methods.Results:The mean (SD) age was 32.3 (6.8) years (range, 15-49 years), whereas the mean (SD) parity was 2.9 (1.2) (range, 1-9). Abnormal cytological findings were detected in 2.9% patients, whereas the remaining smears were negative for any intraepithelial lesion or malignancy. A total of 113 cases were screened positive by one/all methods. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the Papanicolaou test, the VIA, and the VIAM were 24, 98, 42, 96, and 94%; 95, 78, 19, 99, and 79%; and 95, 78, 19, 99, and 79%, respectively, for high-grade lesions.Conclusions:The Papanicolaou test had low sensitivity but high specificity, whereas visual detection methods had a high sensitivity in addition to being cheaper. Alternative methods of screening such as VIA/VIAM can be a valuable alternative to the Papanicolaou test for cervical cancer screening in low resource settings. Visual inspection using magnification devices may be of benefit over VIA in doubtful cases.

Introduction: An important reason for higher cervical cancer incidence in developing countries is lack of effective screening programs like pap smear, aimed at detecting precancerous conditions before they progress to invasive cancer. The potential difficulties in implementing cervical cytology based screening in low-resource settings have prompted the investigation of accuracy of alternative low technology tests such as Visual inspection with acetic acid application [VIA], Visual inspection with acetic acid application with magnification [VIAM], visual inspection on Lugol’s Iodine application [VILI] in early detection of cervical neoplasia .In our study we compared pap smear with VIA to study the accurarcy of VIA as it is simpler and easier technique to be used as screening in low resource settings. Aim: This is a hospital based descriptive, prospective study to evaluate validity of pap smear and VIA techniques as screening tests in identifying cervical lesions. Materials And Methods: After general and systemic examination as a routine,visual local pelvic examination including visualisation of cervix and vagina per speculum and the findings are documented in the proforma .Then VIA and pap smear are done in that order, if any of these tests are positive then cervical biopsy will be taken and further advise to the subject is given. Results: A total of 313 women were involved in the study. The sensitivity of pap smear is 54.5% specificity is 98.9% while that of VIA 95.4% and 97.9%respectively. We found that VIA accuracy was comparatively more than that of pap smear. Conclusion: In low resource settings, usefulness of VIA is more than that of pap smear. We suggest to perform VIA in all the women inspite of having pap smear facility to improve detection rate of cervical lesions and provide better patient councelling and treatment.
