Visual inspection methods for cervical cancer prevention.

The need for simple, cost-effective screening approaches for cervical cancer prevention in low-resource countries has led to the evaluation of visual screening with 3-5% acetic acid. The low reproducibility and wide variation in accuracy reflect the subjective nature of the test. Pooled sensitivity, specificity, positive and negative predictive values were 80%, 92%, 10% and 99%, respectively, for detecting cervical intraepithelial neoplasia grade 2 or worse lesions.

Cancer pattern and survival in a rural district in South India.

Background: Cancer pattern data are rare and survival data are none from rural districts of India.

Methods: The Dindigul Ambilikkai Cancer Registry (DACR) covering rural population of 2 millions in Dindigul district, Tamil Nadu state, South India, registered 4516 incident cancers during 2003-2006 by active case finding from 102 data sources for studying incidence pattern, of which, 1045 incident cancers registered in 2003 were followed up for estimating survival. House visits were undertaken annually for each registered case for data completion.

Education and cancer incidence in a rural population in south India.

Background: Population-based studies describing the association between education and cancer incidence has not yet been reported from India.

Methods: Information on the educational attainment of 4417 cancer cases aged 14 years and above, diagnosed during 2003-2006 in Dindigul district, Tamil Nadu, India, was obtained from the Dindigul Ambilikkai Cancer Registry, which registers invasive cancer cases by active methods from 102 data sources. Population distribution by 5-year age groups and for four educational levels namely no education, education 12 years, was obtained from census data.

Human papillomavirus infection and cervical cancer prevention in India, Bangladesh, Sri Lanka and Nepal.

Although one-third of the world cervical cancer burden is endured in India, Bangladesh, Nepal and Sri Lanka, there are important gaps in our knowledge of the distribution and determinants of the disease in addition to inadequate investments in screening, diagnosis and treatment in these countries. Prevalence of human papillomavirus (HPV) infection among the general populations varies from 7-14% and the age-specific prevalence across age groups is constant with no clear peak in young women. This observation may be the result of a low clearance rate of incident infections, frequent re-infection/reactivation, limited or no data in target high-risk age groups (teenagers), and sexual behavioural patterns in the population.

Cervical and oral cancer screening in India.

Incidence of both cervical and oral cancer are high in India. Although there are no organized cervical or oral screening programmes in the country, a number of research projects are ongoing or recently completed. In cervical screening, a number of studies of visual inspection with various aids and studies of human papillomavirus (HPV) testing are in progress.

Initial results from a randomized trial of cervical visual screening in rural south India.

The impact of a single round of screening of visual inspection with acetic acid (VIA) on cervical cancer incidence and mortality was investigated in a cluster randomized trial in south India. Women 30-59 years of age in 113 clusters in Dindigul District were randomized to VIA screening (57 clusters, 48,225 women) by nurses and to a control group (56 clusters, 30,167 women). 30,577 eligible women were screened between May 2000 and April 2003; 2,939 (9.

Determinants of participation of women in a cervical cancer visual screening trial in rural south India.

The efficacy of a single round of screening of visual inspection with acetic acid (VIA) on cervical cancer incidence and mortality is investigated in a cluster randomized controlled trial in south India. Women aged 30-59 years in 113 clusters in Dindigul District were randomized to VIA screening by nurses (57 clusters, 48,225 eligible women) and to a control group (56 clusters, 30,167 women). 30,577 (63.
