State of the Science of Scale-Up of Cancer Prevention and Early Detection Interventions in Low- and Middle-Income Countries: A Scoping Review

PURPOSE

Cancer deaths in low- and middle-income countries (LMICs) will nearly double by 2040. Available evidence-based interventions (EBIs) for cancer prevention and early detection can reduce cancer-related mortality, yet there is a lack of evidence on effectively scaling these EBIs in LMIC settings.

METHODS

We conducted a scoping review to identify published literature from six databases between 2012 and 2022 that described efforts for scaling cancer prevention and early detection EBIs in LMICs. Included studies met one of two definitions of scale-up: (1) deliberate efforts to increase the impact of effective intervention to benefit more people or (2) an intervention shown to be efficacious on a small scale expanded under real-world conditions to reach a greater proportion of eligible population. Study characteristics, including EBIs, implementation strategies, and outcomes used, were summarized using frameworks from the field of implementation science.

RESULTS

This search yielded 3,076 abstracts, with 24 studies eligible for inclusion. Included studies focused on a number of cancer sites including cervical (67%), breast (13%), breast and cervical (13%), liver (4%), and colon (4%). Commonly reported scale-up strategies included developing stakeholder inter-relationships, training and education, and changing infrastructure. Barriers to scale-up were reported at individual, health facility, and community levels. Few studies reported applying conceptual frameworks to guide strategy selection and evaluation.

CONCLUSION

Although there were relatively few published reports, this scoping review offers insight into the approaches used by LMICs to scale up cancer EBIs, including common strategies and barriers. More importantly, it illustrates the urgent need to fill gaps in research to guide best practices for bringing the implementation of cancer EBIs to scale in LMICs.

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.

Training health care providers to administer VIA as a screening test for cervical cancer: a systematic review of essential training components

BACKGROUND

Training health care providers to administer visual inspection after application of acetic acid (VIA) is paramount in improving cervical cancer screening services for women in low- and middle-income countries. The objective of this systematic review was to create a framework of essential VIA training components and provide illustrating examples of how VIA training programs can be carried out in different clinical settings.

METHODS

A systematic review of PubMed, Embase, and Web of Science (from 2006 to 2021) was undertaken. Our inclusion criteria comprised articles reporting on implemented cervical cancer screening programs using VIA in a screen-and-treat approach. Trained health care providers with any level of health education were included, and the outcome of interest was the reporting of training components. Data were extracted by two reviewers, and a narrative synthesis of the training programs was performed. We developed a framework of seven essential training components and applied it to assess how training courses were conducted in different settings.

RESULTS

13 primary studies were eligible for inclusion, including 2,722 trained health care providers and 342,889 screened women. Most training courses lasted 5-7 days and included theoretical education, practical skill development, and competence assessment. It was unclear how visual aids and training in client counselling and quality assessment were integrated in the training courses. After the training course, nearly all the VIA training programs made provisions for on-job training at the providers' own clinical settings through supervision, feedback, and refresher training.

CONCLUSIONS

This study demonstrates the feasibility of implementing international training recommendations for cervical cancer screening in real-world settings and provides valuable examples of training program implementation across various clinical settings. The diverse reporting practices of quality indicators in different studies hinder the establishment of direct links between these data and training program effectiveness. To enhance future reporting, authors should emphasize specific training components, delivery methods, and contextual factors. Standardized reporting of quality indicators for effective evaluation of VIA training programs is recommended, fostering comparability, facilitating research, and enhancing reporting quality in this field.

Mobile Screening Unit (MSU) for the Implementation of the 'Screen and Treat' Programme for Cervical Cancer Prevention In Pune, India

OBJECTIVES

We are reporting the evaluation of an opportunistic point of care cervical cancer screening initiative in Pune, India using a mobile screening unit (MSU).

METHODS

We conducted 290 cervical cancer screening outreach clinics in the MSU. Screening was performed by trained nurses/ health care providers using visual inspection with 5% acetic acid (VIA). Screen positive women when eligible were treated by thermal ablation during the same sitting. Women with large lesions not eligible for treatment with thermal ablation were referred for colposcopy and treatment.

RESULTS

A total of 10, 925 women were screened between Nov 2016 and June 2019 in 290 outreach clinics in the MSU. The overall screen positivity was 6.6% (95% CI 6.1, 7.0) with a declining trend over time. A total of 304/717 (42.4%, 95% CI 38.7, 46.1) women received treatment with thermal ablation. About 3.6% (11/304) reported minor side effects and 1.6% (5/304) reported lower abdominal pain and all of them subsided after treatment.  Among the 413 women who were advised colposcopy, only 84 (20.33%) women underwent the procedure. Of these 84 women, 64 (76.19%) had normal colposcopy/ histopathology, 7 (8.33%) had CIN1, 2 (2.38%) had CIN 2, 9 (10.71%) had CIN 3 disease and 2 (2.38%) women were diagnosed with invasive cancer.

CONCLUSION

MSUs are useful for providing cervical cancer screening services, using the 'screen and treat' strategy.  Thermal ablation is safe in the field clinics. Additional efforts are needed to improve the compliance for referral of those with large lesions requiring additional visits.
