Social and clinical factors associated with non-adherence to radiotherapy with curative intent in a cancer centre in Peru.
Article in Ecancermedicalscience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Adherence to radiotherapy with curative intent is essential to achieve optimal tumour control and improve survival. In low- and middle-income countries, particularly in rural and multicultural settings, structural and sociocultural barriers can significantly compromise treatment completion. Objective: To identify the social and clinical factors associated with non-adherence to radiotherapy with curative intent and its impact on progression-free survival in patients treated at a Peruvian cancer centre. Methods: A retrospective observational study was conducted that included 254 patients treated with radiotherapy with curative intent between 2020 and 2021. Data were obtained through structured review of medical records and validated surveys. Multivariate logistic regression and survival analysis using Kaplan-Meier curves were applied. Results: Non-adherence was significantly associated with belonging to an indigenous ethnic group (odds ratio (OR): 10.45; 95% confidence interval (CI): 2.34-46.67), lack of access to paved roads (OR: 2.19; 95% CI: 1.10-4.36) and incomplete secondary education (OR: 2.31; 95% CI: 1.33-4.01). These factors were also associated with reduced progression-free survival. Conclusions: Structural and sociocultural determinants significantly influence adherence to radiotherapy in underserved populations. Tailored interventions-such as transport support, intercultural health education and the implementation of hypofractionated protocols-are urgently needed to improve equity in cancer care.
