          Abstract

          Background:

          Breast, cervical, and oral cancers contribute to majority of cancer deaths among women in India. However, there is poor implementation of screening programs at primary health care (PHC). There is a need to understand the perspectives of healthcare providers at PHC level for feasibility of implementation of a cost-effective cancer screening program, particularly in the rural and tribal areas that are under served by cancer services.

          Materials and Methods:

          A continuous medical education (CME) program on “Prevention and early detection of common cancers” was held for all Medical Officers of Palghar District, Maharashtra. A self-administered questionnaire was used to assess the knowledge, attitude, practices, perspectives regarding common cancers, screening methods, and human papilloma virus (HPV) vaccination. A pre- and post-assessment was carried out before the commencement and on completion of the CME among 76 participants.

          Results:

          Knowledge about etiology of common cancers was high; however, awareness of risk factors was low. There were knowledge gaps about HPV vaccination. There was overall improvement about the available screening methods and knowledge of HPV vaccine and dosages after the CME (pretest 65% to posttest 95%). Providers had no experience in performing cervical cancer screening on a routine basis. While the majority of the providers (97%) indicated that screening for cancer was essential and feasible at PHC level; however, training (52%) and resources (53%) would be needed.

          Conclusion:

          Healthcare providers though from the underserved tribal areas, were optimistic to implement screening for common cancers and were willing to take training for the same. This emphasizes the need for educating and training the healthcare providers with simple techniques for effective implementation of cancer screening programs in underserved areas.

          Effect of screening on oral cancer mortality in Kerala, India: a cluster-randomised controlled trial.

          Oral cancer is common in men from developing countries, and is increased by tobacco and alcohol use. We aimed to assess the effect of visual screening on oral cancer mortality in a cluster-randomised controlled trial in India. Of the 13 clusters chosen for the study, seven were randomised to three rounds of oral visual inspection by trained health workers at 3-year intervals and six to a control group during 1996-2004, in Trivandrum district, Kerala, India. Healthy participants aged 35 years and older were eligible for the study. Screen-positive people were referred for clinical examination by doctors, biopsy, and treatment. Outcome measures were survival, case fatality, and oral cancer mortality. Oral cancer mortality in the study groups was analysed and compared by use of cluster analysis. Analysis was by intention to treat. Of the 96,517 eligible participants in the intervention group, 87,655 (91%) were screened at least once, 53,312 (55%) twice, and 29,102 (30%) three times. Of the 5145 individuals who screened positive, 3218 (63%) complied with referral. 95,356 eligible participants in the control group received standard care. 205 oral cancer cases and 77 oral cancer deaths were recorded in the intervention group compared with 158 cases and 87 deaths in the control group (mortality rate ratio 0.79 [95% CI 0.51-1.22]). 70 oral cancer deaths took place in users of tobacco or alcohol, or both, in the intervention group, compared with 85 in controls (0.66 [0.45-0.95]). The mortality rate ratio was 0.57 (0.35-0.93) in male tobacco or alcohol users and 0.78 (0.43-1.42) in female users. : Oral visual screening can reduce mortality in high-risk individuals and has the potential of preventing at least 37,000 oral cancer deaths worldwide.

            Cost-effectiveness of cervical-cancer screening in five developing countries.

            Cervical-cancer screening strategies that involve the use of conventional cytology and require multiple visits have been impractical in developing countries. We used computer-based models to assess the cost-effectiveness of a variety of cervical-cancer screening strategies in India, Kenya, Peru, South Africa, and Thailand. Primary data were combined with data from the literature to estimate age-specific incidence and mortality rates for cancer and the effectiveness of screening for and treatment of precancerous lesions. We assessed the direct medical, time, and program-related costs of strategies that differed according to screening test, targeted age and frequency, and number of clinic visits required. Single-visit strategies involved the assumption that screening and treatment could be provided in the same day. Outcomes included the lifetime risk of cancer, years of life saved, lifetime costs, and cost-effectiveness ratios (cost per year of life saved). The most cost-effective strategies were those that required the fewest visits, resulting in improved follow-up testing and treatment. Screening women once in their lifetime, at the age of 35 years, with a one-visit or two-visit screening strategy involving visual inspection of the cervix with acetic acid or DNA testing for human papillomavirus (HPV) in cervical cell samples, reduced the lifetime risk of cancer by approximately 25 to 36 percent, and cost less than 500 dollars per year of life saved. Relative cancer risk declined by an additional 40 percent with two screenings (at 35 and 40 years of age), resulting in a cost per year of life saved that was less than each country's per capita gross domestic product--a very cost-effective result, according to the Commission on Macroeconomics and Health. Cervical-cancer screening strategies incorporating visual inspection of the cervix with acetic acid or DNA testing for HPV in one or two clinical visits are cost-effective alternatives to conventional three-visit cytology-based screening programs in resource-poor settings.

              Effect of VIA screening by primary health workers: randomized controlled study in Mumbai, India.

              Cervical cancer is the leading cause of cancer mortality among women in India. Because Pap smear screening is not feasible in India, we need to develop effective alternatives. A cluster-randomized controlled study was initiated in 1998 in Mumbai, India, to investigate the efficacy of visual inspection with acetic acid (VIA) performed by primary health workers in reducing cervical cancer mortality. Four rounds of cancer education and VIA screening were conducted at 24-month intervals in the screening group, whereas cancer education was offered once at entry to the control group. The study was planned for 16 years to include four screening rounds followed by four monitoring rounds. We present results after 12 years of follow-up. Poisson regression method was used to calculate the rate ratios (RRs); two-sided χ(2) was used to calculate the probability. We recruited 75360 women from 10 clusters in the screening group and 76178 women from 10 comparable clusters in the control group. In the screening group, we achieved 89% participation for screening and 79.4% compliance for diagnosis confirmation. The incidence of invasive cervical cancer was 26.74 per 100000 (95% confidence interval [CI] = 23.41 to 30.74) in the screening group and 27.49 per 100000 (95% CI = 23.66 to 32.09) in the control group. Compliance to treatment for invasive cancer was 86.3% in the screening group and 72.3% in the control group. The screening group showed a statistically significant 31% reduction in cervical cancer mortality (RR = 0.69; 95% CI = 0.54 to 0.88; P = .003). VIA screening by primary health workers statistically significantly reduced cervical cancer mortality. Our study demonstrates the efficacy of an easily implementable strategy that could prevent 22000 cervical cancer deaths in India and 72600 deaths in resource-poor countries annually.
