# The preventable burden is a delivery problem, from stigma to treatment failure

*Three preprints posted on October 29 link cervical cancer stigma in Nepal, preventable infection-related cancers among migrants in the EU, and tuberculosis burden in India to the same gap: what works does not reliably reach the people who need it.*

## Key facts

- In a preprint survey of women in urban Nepal, formal education was associated with lower cervical cancer stigma, and awareness that cervical cancer is preventable and treatable was also associated with lower stigma. (self-reported) [cites: 1793318668762105521]
- In a preprint model, newly arrived migrants in the EU were projected to experience 635,000 lifetime infection-related cancer cases, with HPV vaccination and cervical screening potentially preventing 65 percent and 60 percent of cervical cancer cases respectively. (self-reported) [cites: 1793315963541253515]
- In a preprint modelling study in India, treatment failure accounted for 63 percent of infectiousness-weighted tuberculosis burden, with a median effective infectious time of 16 months versus 3 months without failure. (self-reported) [cites: 1793315817530331309]
- In a preprint, a combined package of active case finding, diagnostic improvement and treatment support reduced projected 2035 tuberculosis incidence by 34 percent. (self-reported) [cites: 1793315817530331309]

## Stigma blocks the first step

In a preprint based on a survey of women living in urban Nepal, formal education was associated with lower cervical cancer stigma scores, and awareness that cervical cancer is preventable and treatable was also associated with lower stigma. [cites: 1793318668762105521]

The preprint also reports higher stigma scores for Janjati women and for Dalit and Madhesi women than for Brahmin and Chettri women. The pattern suggests that general awareness campaigns may miss the groups carrying the heaviest stigma, and that specific disease knowledge, rather than name recognition alone, tracks with lower stigma. [cites: 1793318668762105521]

That distinction matters for prevention. If stigma discourages engagement with screening, then a programme that raises awareness of the disease name without explaining prevention, treatability, signs and symptoms leaves the barrier largely intact, according to the associations reported in the preprint.

## A large preventable share, on paper

A second preprint models the expected and potentially preventable burden of infection-related cancer among newly arrived migrants in the European Union. It projects 635,000 lifetime cases of infection-related cancers, covering liver, cervical and gastric cancers, in that population. [cites: 1793315963541253515]

The modelled prevention shares are large. ECDC-recommended hepatitis interventions could prevent 15 percent of liver cancer cases among newly arrived migrants, HPV vaccination could prevent 65 percent of cervical cancer cases and cervical screening 60 percent among eligible migrants, and H. pylori screen-and-treat interventions could prevent 44 percent of gastric cancer cases among all newly arrived migrants. [cites: 1793315963541253515]

The preventable share is therefore a measure of what screening and vaccination could do if delivered, not a forecast of what will happen without delivery systems to match. [cites: 1793315963541253515]

## Treatment failure drives transmission

A third preprint, an agent-based modelling study of tuberculosis in India, shows the same delivery gap from the treatment side. Treatment failure, with or without diagnostic failure, accounted for 63 percent of infectiousness-weighted tuberculosis burden in the model. [cites: 1793315817530331309]

The time dimension explains why that share is so large. Median effective infectious time was 16 months for patients with treatment failure, compared with 3 months for those with no failure. A patient who starts treatment but does not complete it successfully therefore remains infectious far longer than a patient whose treatment succeeds, which changes how burden should be counted. [cites: 1793315817530331309]

The preprint tests a combined response rather than a single fix. A package of active case finding, diagnostic improvement and treatment support reduced projected 2035 tuberculosis incidence by 34 percent, with a 95 percent confidence interval of 31 to 36 percent. No single element of that package, on its own, is presented as the answer. [cites: 1793315817530331309]

## The common thread

Read together, the three preprints describe prevention as a chain with several weak links. Knowledge and lower stigma must come before screening in Nepal, screening and vaccination must actually reach newly arrived migrants in the EU, and diagnosis must be followed by treatment support that prevents failure in India. A break at any link leaves the burden in place even when the intervention itself is known. [cites: 1793318668762105521, 1793315963541253515, 1793315817530331309]

Each study is a preprint, so its numbers should be read as modelled or surveyed estimates awaiting further validation, not as settled programme results. That is a further reason to treat the 34 percent reduction as a modelled scenario rather than a promised result. [cites: 1793315817530331309]

## What is still unresolved

- No longitudinal data in the Nepal study confirming whether knowledge interventions reduce stigma over time, or how stigma affects actual screening uptake.
- Whether targeted knowledge programmes reach the higher-stigma groups identified in the Nepal survey.

## Decision card

- **Useful for:** Public health planners designing screening, vaccination and treatment-support programmes; Clinicians and programme managers tracking where patients drop out of a care cascade
- **Not for:** Forecasting programme results from modelled prevention shares alone; Assuming awareness alone will raise screening uptake
- **Compare against:** Observed screening uptake and treatment completion rates in the same populations; Cost-effectiveness analyses for the proposed interventions
