Table 2:
Target population | Delivery level | Country Examples | |
---|---|---|---|
Improved cancer surveillance in MICs | |||
Population based cancer registries | All cancer cases in a defined population catchment area | National and subnational level, with central coordination | Zimbabwe National Cancer Registry, Kampala Cancer Registry (subnational)34 |
Participation in epidemiological & clinical studies of cancer risk factors | General population in LMICs | Community based research | H3 Africa consortium on molecular epidemiology and risk factors for NCDs108 |
Prevention of modifiable risk factors | |||
Tobacco taxation | General population, current and potential future tobacco users | National, through legislation increasing excise taxes on tobacco | Philippines – introduction of high excise tobacco taxes in 2012 led to an estimated 3 million fewer smokers within 3 years31 |
HPV vaccination | Girls aged 9-12 years | Primary care/community based School based for those enrolled |
A number of MICs including Zambia & Ethiopia have introduced community and school-based HPV vaccination program over the past 10 years, achieving >90% coverage 109 |
Targeted & opportunistic cancer screening | |||
Point of care diagnostics: HPV testing | Sexually-active women, with focus on high risk subpopulations: HIV(+), sex-workers, tobacco users | Primary care or community based | Argentina – used an existing network of trained CHWs to implement self-collection HPV tests among high-risk groups to increase coverage 4 fold110 |
Screen & treat: VIA + HPV testing | As above | Primary care or community based | Zambia: since 2006 Zambia has used its HIV program infrastructure to introduce the Cervical Cancer Prevention Program, a nurse driven screen and treat program which initially focused on women with HIV and later expanded coverage to oter women, reaching 58,000 women within it’s first 5 years60 |
Clinical breast examination (conditional recommendation) | Women aged 30 years+ | Primary care or community based | Malawi – delivery of CBE through trained lay women, implemented in primary care health clinics among women presenting for reasons other than a breast concern70 |
Familial/hereditary risk stratification | First-degree relatives of patients with breast, colorectal cancers | Primary care (family history screening tools), secondary/tertiary care (familial cancer registries, kindred studies) | Nigeria – first-degree relative (FDR) registry maintained within African Research Group for Oncology’s multi-site hospital-based colorectal cancer registry. FDRs in registry invited to participate in high risk screening studies111 |
Earlier detection of symptomatic cancers | |||
Risk stratification tools | Symptomatic patients on first contact with health provider | Primary care | Nigeria – development of a cardinal symptoms tool for colorectal cancer, to prompt referral for further investigation of symptoms92 |
Public awareness campaigns | General population | Community based | Rwanda (a LIC) introduced a public awareness campaign for women’s cancers in 2020 as part of it’s National Cancer Control Plan112 |
Provider education | Community health workers, primary care | Community health and primary care facilities | Peru: Community-based Program for Breast Health, a collaboration between PATH, the Peruvian Ministry of Health, the National Cancer Institute (Lima), and the Regional Cancer Institute (Trujillo). Phased implementation of public and primary care provider education on breast cancer diagnosis improved capacity for early diagnosis among first-level health workers113 |
Point of care diagnostics | Symptomatic patients presenting to primary care or a first level hospital | All levels of the health system but targeted at primary care, first level hospitals without advanced imaging and pathology capacity | Nigeria – prospective evaluation of urine-based POC testing for colorectal cancer using metabolomics114 |
