“…There was no significant difference between the prevalence of negative results from this study and that presented by Naud et al (2001), who sampled 100 women in Brazil 24 .

“…Even though these issues contributed to a high unsatisfactory rate, the study had significantly lower unsatisfactory results compared with Stewart (1996) in a similar study population 21 . In other developing countries, studies demonstrate varying rates of unsatisfactory smears 14,24 . There was a significant higher number of unsatisfactory Pap smears in this study compared with the Victorian Cervical Cytology Registry (VCCR) 25 .…”

Objective: To use the Pap smear to establish a recent prevalence of cervical abnormalities within a select population in Vanuatu, a developing country. Methods: Cervical smears (n=907) were collected from Ni‐Vanuatu women from both urban and rural islands within Vanuatu between August 2001 and September 2005. Results: The prevalence of low‐grade epithelial abnormalities for the total population was 2.9% and the prevalence of the high‐grade epithelial abnormalities/cancer was 2.0%. There was a significant difference (p<0.05) in prevalence of high‐grade epithelial abnormalities/cancer between the urban and rural populations sampled, with a higher prevalence in the urban population. Conclusions: The prevalence of pre‐cancer and cancer in Vanuatu is high compared with Victorian (Australian) statistics yet comparable with other developing countries with no cervical screening programs available. Implications: This study will hopefully assist in future planning of women's health programs and relevant preventive strategies to combat cervical cancer in Vanuatu.

“…Cervical cancer is the second most common cancer in women throughout the world, and it is the leading cause of cancer death among women in underdeveloped countries ( 1–3 ) . The incidence and mortality rate of cervical cancer have markedly decreased in developed countries since cytologic cervical cancer screening was introduced more than 50 years ago ( 3–6 ) .…”

The aim of this study was to estimate the sensitivity and specificity of visual inspection of the uterine cervix with acetic acid (VIA) as a screening test for cervical carcinoma and its precursors. One thousand and two hundred eligible women were screened by VIA and Papanicolaou smear. Those positive on one or both of these screening tests (n = 308) or those who had clinically suspicious lesions, even if the tests were negative [25% of remainders (n = 290)], were referred for colposcopy. Three hundred and fifty five of 598 women at colposcopy underwent biopsies or endocervical curettage. Those with cervical intraepithelial neoplasia I (CIN I) or worse lesions, diagnosed by histology, were considered true positive. VIA was positive in 191 women (16.1%). In 175 true-positive cases, VIA detected 130 cases, yielding a sensitivity of 74.3% and a specificity of 94%. By considering atypical squamous cell of undetermined significance or worse lesions on Papanicolaou smear as referring threshold for colposcopy, the sensitivity and specificity of cytology were 72 and 90.2%, respectively. In conclusion, the sensitivity and specificity of VIA is high and comparable with that of cytology. Hence, VIA can be undertaken as a feasible method of screening in cervical cancer in countries where access to cytopathology is limited.
