Cervical Cancer Care Continuum in South India: Evidence from a Community-based Screening Program

Community cancer screening at primary care level in Northern India: determinants and policy implications for cancer prevention

OBJECTIVE

Despite the established cancer screening programme for oral, breast and cervical cancer by the Government of India, the screening coverage remains inadequate. This study aimed to describe the determinants for oral, breast and cervical cancer prevention in a rural community at the primary care level of Northern India and its policy implications.

DESIGN

This was a camp-based project conducted for 1 year, using oral visual examination, clinical breast examination and visual inspection of cervix by application of 5% acetic acid according to primary healthcare operational guidelines. During the project, screen-positive participants were followed through reverse navigation. Information about socio-demographic profile, clinical and behavioural history and screening were collected. Predictors for screen-positivity and follow-up compliance were identified through multivariable analysis.

SETTINGS

Based on the aim of project, one of the remotely located and low socioeconomic rural blocks, having 148 villages (estimated population of 254 285) in Varanasi district, India was selected as the service site. There is an established healthcare delivery and referral system as per the National Health Mission of Government of India. Oral, breast, gallbladder and cervical cancers are the leading cancers in the district.

PARTICIPANTS

We invited all men and women aged 30-65 years residing in the selected block for the last 6 months for the screening camps. Unmarried women, women with active vaginal bleeding, those currently pregnant and those who have undergone hysterectomy were excluded from cervical cancer screening.

RESULTS

A total of 14 338 participants were screened through 190 camps and the majority (61.9%) were women. Hindu religion, tobacco use, intention to quit tobacco and presence of symptoms were significantly associated with screen-positivity. Nearly one-third (220; 30.1%) of the screened-positives complied with follow-up. Young age and illiteracy were significantly associated with lower compliance.

CONCLUSION

Poor follow-up compliance, despite the availability of tertiary cancer care, patient navigation, free transportation and diagnostic services, calls for research to explore the role of contextual factors and develop pragmatic interventions to justify 'close the care gap'. Community cancer screening needs strengthening through cancer awareness, establishing referral system and integration with the National Tobacco Control and Cancer Registry Programmes.

Challenges in Cervical Cancer Prevention: Real-World Scenario in India

Satinder KaurIn spite of global falling trends, cervical cancer remains a major healthcare challenge for India, South Asia Association for Regional Cooperation region, and other low- and middle-income countries. Our survey was to document the real-world challenges that still exist in India. A total of 316 eligible and complete responses to the 21 questions were analyzed. Screening of mothers and vaccinating their daughters was considered as the most important strategy to prevent cervical cancer by 65.8% (208/316). Screening was offered to all asymptomatic eligible females by 79% (250/316). Improvement in screening rates requires promoting the national program (67.7%; 214/316), strengthening existing infrastructure (62%; 196/316), regular training of primary healthcare workers (57.6%; 182/316), and increasing awareness among schools and colleges (57.9%; 183/316). Almost all responders (93%; 294/316) wanted to have human papillomavirus (HPV) vaccination included in the national immunization schedule. Cost of vaccine was considered a major roadblock. If it became available at INR 250 per dose, 96.8% (306/316) respondents would recommend it for all eligible patients. With the impending availability of this indigenous tetravalent HPV vaccine jointly produced by Department of Biotechnology, Govt of India and Serum Institute of India, the war against cervical cancer just got easier.

Cervical cancer elimination in indian context: Moving from barriers to facilitators

It has been 46 years since the launch of cancer control programs in India and yet the recent National Family Health Survey (fifth round, 2019-2021) has reported that just 1.9% of women aged 30-49 years have ever undergone cervical cancer screening. The cost of delayed diagnosis of cervical cancer and its treatment is overwhelming, and the rural population takes the worst hit. It is the need of the hour that the Indian health system and policymakers identify the barriers and facilitators for cervical cancer early detection and provide pragmatic solutions so that the targets of cervical cancer elimination can be achieved in a timely manner.

Cervical Cancer Screening Cascade for women living with HIV: a cohort study from Zimbabwe

Countries with high HIV prevalence, predominantly in sub-Sahahran Africa, have the highest cervical cancer rates globally. HIV care cascades successfully facilitated the scale-up of antiretroviral therapy. A cascade approach could similarly succeed to scale-up cervical cancer screening, supporting WHO's goal to eliminate cervical cancer. We defined a Cervical Cancer Screening Cascade for women living with HIV (WLHIV), evaluating the continuum of cervical cancer screening integrated into an HIV clinic in Zimbabwe. We included WLHIV aged ≥18 years enrolled at Newlands Clinic in Harare from June 2012-2017 and followed them until June 2018. We used a cascade approach to evaluate the full continuum of secondary prevention from screening to treatment of pre-cancer and follow-up. We report percentages, median time to reach cascade stages, and cumulative incidence at two years with 95% confidence intervals (CI). We used univariable Cox proportional hazard regressions to calculate cause-specific hazard ratios with 95% CIs for factors associated with completing the cascade stages. We included 1624 WLHIV in the study. The cumulative incidence of cervical screening was 85.4% (95% CI 83.5-87.1) at two years. Among the 396 WLHIV who received screen-positive tests in the study, the cumulative incidence of treatment after a positive screening test was 79.5% (95% CI 75.1-83.2) at two years. The cumulative incidence of testing negative at re-screening after treatment was 36.1% (95% CI 31.2-40.7) at two years. Using a cascade approach to evaluate the full continuum of cervical cancer screening, we found less-than 80% of WLHIV received treatment after screen-positive tests and less-than 40% were screen-negative at follow-up. Interventions to improve linkage to treatment for screen-positive WLHIV and studies to understand the clinical significance of screen-positive tests at follow-up among WLHIV are needed. These gaps in the continuum of care must be addressed in order to prevent cervical cancer.

Cervical Cancer Prevention Efforts in India

Purpose

Cervical cancer is one of the leading cancers among women in India. Its prevention and control require a concerted effort to improve awareness among women regarding primary and secondary prevention strategies as well as access to care for treatment and palliation. A focused strategy is important to reach the World Health Organization’s targets for cervical cancer elimination, due to be completed by 2030.

Methods

Currently available literature was reviewed regarding cervical cancer prevention strategies in India including various national programmes and other initiatives on the part of government, non-governmental organizations and professional organizations. Their applicability to the present situation was assessed.

Results

National programmes need to build on success stories of various states and neighbouring countries as well as to audit the performance. Strengthening of cancer registries and improvement of linkages between different healthcare levels with incorporation of task-shifting, adding digital technology and supporting programmes that promote women’s welfare and health will also provide synergy to cancer control programmes. In the current pandemic era, HPV self-sampling can be an ideal method for screening. The development of an affordable, point-of-care HPV test is urgently needed to facilitate its introduction in low- and middle-income countries. HPV vaccination efforts need to be speeded up.

Conclusion

Scaling up of cervical cancer prevention with inclusion of widespread HPV vaccination and primary HPV test should be the new standard of care.
