"If I am here, it is because the system failed": a critical qualitative study of global commercial clinical trials for advanced cancer in Chile.
Article in Globalization and health, 2025. 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
backgroundThe pharmaceutical industry is a key global health actor given its crucial role in the development and testing of medicines. Within Latin America, Chile currently has the highest number of multinational commercial clinical trials per inhabitant, predominantly for oncological therapies. Insufficient attention has been paid to context-specific conditions that enable clinical trials' successful implementation in the Global South. In examining what makes Chile an attractive hub for commercial trials and why patients enroll in them, this study seeks to elucidate the interplay among the pharmaceutical industry, health systems, and societies. We analyze how trial providers, cancer practitioners, and patient participants draw from their own lived experience to make sense of local healthcare, health policies and global pharmaceutical market trends, amid global health crises.
methodsUsing a critical political economy of global health framework, we conducted a critical ethnography in 2022-23 at a tertiary cancer center that is the lead recruiter of patients into oncology commercial trials in Santiago, Chile. In-depth interviews, participant observation, and document gathering were conducted, with materials analyzed through thematic content analysis using Nvivo12.
resultsForty-seven subjects -fourteen patients, four caregivers, and twenty-nine providers- were interviewed and/or shadowed. The main theme, "A failed (health) system" reveals a perception that the growing presence of commercial clinical trials for advanced cancer works synergistically with a deficient health system. Subthemes of political economy levels of (mal)functioning, were grouped as follows: (i) the COVID-19 pandemic and the global organization of commercial trials; (ii) national factors (health services and post-trial access policies); and (iii) community/relational factors (palliative care and unaffordability of high-cost drugs). Clinical trials were experienced as an exit strategy from a broken healthcare system, even as participants regarded the pricing strategies of anticancer therapies acritically.
conclusionsThe conditions that make Chile an attractive hub for cancer commercial clinical trials are determined by an interplay of global, national, and community-level structural arrangements between public and private actors. Chile serves as an important global health case study on the role of the pharmaceutical industry in capitalizing on systemic healthcare failures to advance clinical research on metastatic cancer.
