Abstract

Content of image described in text.

Cancer stigma, both underaddressed and understudied, remains a pervasive challenge in sub-Saharan Africa. Currently, the region is experiencing rising cancer incidence alongside some of the lowest cancer survival rates worldwide. With complex and multifaceted sociocultural factors contributing to this stigma and subsequent lack of screening, low treatment adherence and poorer health outcomes, it is critical to implement effective interventions in the region, at both the clinical and policy levels. To achieve a path forward, it is necessary to create targeted efforts that incorporate existing infrastructure and key cultural contexts.

Comments

Dear Dr. Bass and Dr. Chibanda,

Please consider our comment, titled: “The growing and urgent need for interventions to mitigate cancer-related stigma in sub-Saharan Africa,” by Nosayaba Osazuwa-Peters, Brandon Knettel, Huda Haque, Judith Mwobobia, Megan Huchko, Kim Madundo, Furaha Serventi, Blandina Mmbaga, and Kristin Schroeder.

Cancer-related stigma remains a significant barrier to care globally, particularly across the sub-Saharan African region where incidence is rapidly rising and survival rates are among the lowest worldwide. While HIV-related stigma in the region has been relatively well-quantified, cancer-related stigma and its effects on patients’ mental health remain overlooked from both research and interventional perspectives. Drawing on qualitative data and established cultural/societal contributors to cancer-related stigma in the region, this comment calls for urgent attention to research and interventional gaps. Specifically, we propose that multilevel, sensitive interventional strategies are crucially needed to address the rising incidence of cancer and associated mental health implications. Interventions should engage with various aspects and the existing cultural infrastructure of sub-Saharan African society, including traditional and religious healers, family networks, and policies to support the mental health of patients.

Given the focus of this comment on global mental health and the need for interventional changes regarding sociocultural stigma and cancer outcomes, we believe it will be of interest to Global Mental Health’s readership. We are grateful for the opportunity to submit our work here and are thankful for your consideration.

Lastly, we declare the following:

1. This is an original work that is not being considered for publication elsewhere, either in whole, or part.

2. The views and opinions stated in this work are solely those of the authors, and do not represent the view of employers, or of any organization or corporation. All conflicts of interest have been declared, as well as coauthors’ funding information.

3. We confirm that all authors had full access to all aspects of the research, participated in writing and approving this manuscript for publication, and take final responsibility for the paper.

Sincerely,

Conflict of interest statement

Reviewer declares none.

Comments

This is a well written review that makes a compelling case for interventions to mitigate cancer related stigma in Sub -Saharan Africa.

1. From the evidence adduced and the arguments advanced, it is apparent that policy makers have a crucial, if not the most crucial role in enabling the interventions suggested from funding to promulgating policies that help create a practice environment which enables cancer related stigma to be effectively addressed. It would therefore make the review even better if you add suggestions on how policy makers can be brought on board because without their buy in the status quo will remain even with well written papers like this.

2. The sentence (line 85-88) “In the context of sub-Saharan Africa, stigma around cancer is often driven by deeply rooted cultural misconceptions about the illness—for example, there are prevalent beliefs that religious punishment manifests as cancer, or that the disease can be contagious, spread through food or clothing” needs a reference.

Comments

The manuscript addresses an important and underexplored topic in global mental health; however, the central research question and its contribution relative to existing literature should be articulated more explicitly in the Introduction.

The rationale for the chosen study design and analytical framework requires clearer justification, particularly in relation to alternative approaches commonly used in this field.

Key concepts and constructs should be more precisely defined early in the manuscript to avoid ambiguity in interpretation, especially for readers from diverse disciplinary backgrounds.

The description of data sources would benefit from greater transparency regarding coverage, representativeness, and known limitations, particularly in low-resource settings.

Additional detail is needed on inclusion and exclusion criteria to clarify how the analytic sample was derived and to support reproducibility.

The methods section should more clearly explain how potential sources of bias (e.g., measurement error, missing data, or reporting heterogeneity across regions) were addressed or mitigated.

Statistical methods require more detailed reporting, including assumptions underlying the models used and how these assumptions were assessed.

The handling and interpretation of uncertainty should be strengthened, with clearer explanation of confidence or uncertainty intervals and their implications for inference.

Results would benefit from improved structure, with clearer separation between descriptive findings and model-based estimates.

The manuscript should more consistently distinguish between absolute measures and relative or standardized metrics to prevent misinterpretation.

Several key findings are presented with limited contextualization; stronger linkage to prior empirical evidence would enhance interpretability.

The Discussion occasionally overstates causal implications; language should be more carefully framed to reflect the observational nature of the data.

Greater attention should be given to heterogeneity across regions, populations, or subgroups, including clearer discussion of possible drivers of observed differences.

Limitations are acknowledged but could be expanded to more fully address issues of data sparsity, construct validity, and generalizability.

The policy and practice implications would benefit from sharper focus, prioritizing a smaller number of actionable recommendations grounded directly in the study’s findings.

Figures and tables are generally informative, but captions should be expanded to allow them to be interpreted independently of the main text.

Some figures appear dense and may benefit from simplification or redistribution to supplementary materials.

Terminology and notation should be standardized throughout the manuscript to improve clarity and coherence.

Redundancies between the Results and Discussion sections should be reduced to enhance readability.

A careful editorial review is recommended to address minor inconsistencies in formatting, references, and statistical reporting.

Recommendation: The growing and urgent need for interventions to mitigate cancer-related stigma in sub-Saharan Africa — R0/PR5

Comments

The manuscript has an important topic with clear relevance to global mental health, policy, and cancer care in low resource settings. All three reviewers recognize the significance of the issue and the potential contribution of the review, particularly its emphasis on multilevel, culturally grounded interventions.

However, the reviewers raised some concerns that of the need for a major revision. Addressing these comments will enhance the manuscript clarity, credibility, and policy relevance.

Additionnaly to this:

-although the manuscript is labeled as a “Review”….., it does not describe how the literature was identified, selected, leaving readers unable to judge rigor and completeness. This is a substantive methodological weakness that prevents the paper from meeting expected standards for narrative, scoping or systematic reviews.

-In the first sentence “ Globally, stigma plays a significant yet largely unaddressed role in cancer mortality..” yet manuscript focuses almost exclusively on sub-Saharan Africa without contextualizing findings against global research trends.

-it does not provide actionable or evidence-based pathways forward. There is no categories of interventions are defined. This can be policy…… psychosocial.., clinical... No actors delivery platforms are identified example primary care, CHWs or the hospitals..

So I recommend Major Revision, and invite the authors to carefully and comprehensively revise the manuscript.

Comments

The Introduction should more explicitly situate the research question within current global mental health policy frameworks, clarifying how the findings may inform scaling of mental health services.

Greater clarity is needed regarding the theoretical or programmatic model underpinning the intervention or service being evaluated, including how it aligns with existing mental health care frameworks.

The description of participant recruitment procedures should be expanded to clarify whether consecutive, convenience, or purposive sampling strategies were used.

The manuscript should more clearly state how participant retention was monitored and whether attrition may have influenced the final analytic sample.

The authors should provide additional detail regarding fidelity of implementation, including whether standardized procedures or monitoring mechanisms were used to ensure consistent intervention delivery.

Greater attention should be given to contextual factors (e.g., health system capacity, cultural perceptions of mental illness, workforce availability) that may influence implementation outcomes.

The manuscript would benefit from clearer differentiation between feasibility outcomes, effectiveness outcomes, and implementation outcomes.

The measurement tools used to assess mental health outcomes should be more thoroughly described, including information on cultural adaptation, translation procedures, and psychometric validation.

The statistical analysis section should clarify whether clustering or site-level variation was considered, particularly if data were collected across multiple facilities or communities.

The manuscript would be strengthened by including a brief justification for the chosen follow-up duration and its adequacy for capturing meaningful mental health change.

The Results section should more clearly prioritize the primary outcomes, as currently several secondary findings receive comparable emphasis.

The authors should clarify whether any subgroup analyses were prespecified or conducted post hoc.

Greater transparency is needed regarding potential sources of implementation variability across sites or providers.

The Discussion should more explicitly consider alternative explanations for the observed outcomes, including contextual changes unrelated to the intervention.

The manuscript would benefit from a deeper discussion of scalability and sustainability, particularly with respect to financial, workforce, and health system constraints.

Equity considerations should be more explicitly addressed, including whether the intervention reached underserved or marginalized populations.

The limitations section should discuss the potential influence of participant expectations or provider enthusiasm on reported outcomes.

The policy implications should be more cautiously framed, emphasizing the need for replication in diverse contexts before large-scale adoption.

The conclusions would be strengthened by more clearly distinguishing between findings supported directly by the data and broader programmatic recommendations.

Tables and figures could be refined to improve readability, particularly by simplifying dense data presentations.

The manuscript would benefit from a brief statement regarding data transparency and availability to enhance reproducibility.

Comments

The manuscript has improved and addresses several of my comments, particularly regarding intervention frameworks and policy relevance. However, the absence of any description of how literature was identified remains a significant methodological gap, even for a narrative review. Most narrative reviews include a brief description of how literature was identified, such as: databases searched, search terms, time frame, inclusion focus (e.g., stigma, oncology, mental health)
