Crit Rev Oncol Hematol 2024; 199:104364. [PMID: 38729319 DOI: 10.1016/j.critrevonc.2024.104364] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Accepted: 04/15/2024] [Indexed: 05/12/2024] Open
Abstract
Inter-professional collaboration could improve timely access and quality of oncogenetic services. Here, we present the results of a scoping review conducted to systematically identify collaborative models available, unpack the nature and extent of collaboration proposed, synthesize evidence on their implementation and evaluation, and identify areas where additional research is needed. A comprehensive search was conducted in four journal indexing databases on June 13th, 2022, and complemented with searches of the grey literature and citations. Screening was conducted by two independent reviewers. Eligible documents included those describing either the theory of change, planning, implementation and/or evaluation of collaborative oncogenetic models. 165 publications were identified, describing 136 unique interventions/studies on oncogenetic models with somewhat overlapping collaborative features. Collaboration appears to be mostly inter-professional in nature, often taking place during risk assessment and pre-testing genetic counseling. Yet, most publications provide very limited information on their collaborative features, and only a few studies have set out to formally evaluate them. Better quality research is needed to comprehensively examine and make conclusions regarding the value of collaboration in this oncogenetics. We propose a definition, logic model, and typology of collaborative oncogenetic models to strengthen future planning, implementation, and evaluation in this field.

Shain J, Michel A, May MS, Qunaj L, El-Sadr W, Chung WK, Appelbaum PS, Jacobson JS, Justman J, Neugut AI. Cancer genetic mutation prevalence in sub-Saharan Africa: A review of existing data. Semin Oncol 2023; 50:123-130. [PMID: 38171987 DOI: 10.1053/j.seminoncol.2023.12.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 12/15/2023] [Accepted: 12/16/2023] [Indexed: 01/05/2024]
Abstract
BACKGROUND Cancer represents a leading cause of death worldwide. Germline mutations in several genes increase the risk of developing several cancers, including cancers of the breast, ovary, pancreas, colorectum, and melanoma. An understanding of the population prevalence of pathogenic germline variants can be helpful in the design of public health interventions, such as genetic testing, which has downstream implications for cancer screening, prevention, and treatment. While population-based studies of pathogenic germline variants exist, most such studies have been conducted in White populations. Limited data exist regarding the prevalence of germline mutations within sub-Saharan African populations. MATERIALS AND METHODS We identified countries defined as sub-Saharan Africa by the World Bank and conducted a scoping literature review using PubMed. For each country, we identified and summarized studies that focused on the prevalence of germline genetic mutations with sample sizes >10 and in a population directly from sub-Saharan Africa, either with or without diseases associated with the relevant genetic mutations. Studies that evaluated the prevalence of somatic or likely benign variants were excluded. RESULTS Within the 48 countries in sub-Saharan Africa, we identified 34 studies which meet the inclusion criteria. Twenty studies were conducted in South Africa, Nigeria, or Burkina Faso; four countries had more than two published papers. We found that 33 of 48 countries in sub-Saharan Africa lacked any genetic studies. Notably, there has been an increase in relevant studies starting in 2020. Importantly, of the 34 studies identified, 29 included data on BRCA1 or BRCA2. Data on the prevalence of mutations contributing to familial cancer syndromes other than BRCA1 and BRCA2 was limited. CONCLUSIONS While some progress has been made towards understanding the prevalence of germline mutations in cancer susceptibility genes, the characterization of genetic mutations among sub-Saharan African populations remains strikingly incomplete. Given the genetic diversity in the region, there remains a great need for large-scale, population-based studies to understand the prevalence of germline pathogenic variants and adequately capture all the subpopulations in this part of the world.

Feasibility of cancer genetic counselling and screening in Cameroon: perceived benefits and barriers. Ecancermedicalscience 2023; 17:1588. [PMID: 37799957 PMCID: PMC10550300 DOI: 10.3332/ecancer.2023.1588] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2022] [Indexed: 10/07/2023] Open
Abstract
Because there was no genetic testing service in Cameroon, we assessed the acceptance, perceived benefits and barriers and willingness to pay for genetic cancer screening in Cameroon amongst patients with cancers. We carried out a hospital-based, cross-sectional study on adult cancer patients at the Yaoundé General Hospital and the non-Governmental Organisation Solidarity Chemotherapy between February 1, 2021, and December 31, 2021. This was a convenience sampling that included all consenting patients. Qualitative and quantitative data were analysed by Epi info version 7 and SPSS version 20. Our study included 160 (87.5% females) cancer patients, whose ages ranged from 20 to 82 years, with a mean of 49.9 ± 13.0 years. Only 11.9% had undergone some form of genetic counselling or information sessions, and most found this to be helpful in terms of increased knowledge and prevention strategies (13, 68.4%). Almost all participants (156, 97.5%) stated they will like their relatives to undergo genetic counselling. Of these, 151 (94.4%) expressed their desire for their relatives to discuss their cancer risk with a specialist. Perceived benefits of genetic testing included cancer prevention (108, 67.5%) and motivation of self-examination (81, 50.6%). Prominent possible barriers included the cost (129, 80.6%), unavailability of equipment (49, 30.6%) and anticipated anxiety (40, 25.0%). However, a majority of the participants (156, 97.5%) were willing to test for genetic mutations. One hundred and thirty-five (84.4%) participants were willing to pay for genetic testing, with the majority of them (71.8%) ready to pay between $16.7 and $100. Almost all of the participants expressed their willingness to receive cancer genetic counselling and testing but the cost became the main barrier. This pilot study will serve as a guide to the processes of establishing a cancer risk assessment clinic in Cameroon.
