Cancer stem cells and drug resistance in cancer: molecular mechanisms and therapeutic targets.
Review in Molecular biomedicine, 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
Cancer therapy has advanced substantially through targeted therapies and immunotherapy; however, durable clinical responses remain limited by the development of drug resistance. Increasing evidence identifies cancer stem cells (CSCs) as central drivers of therapeutic failure, tumor recurrence, metastasis, and minimal residual disease. CSCs possess self-renewal and differentiation capacities together with remarkable adaptability under therapeutic stress, enabling long-term tumor maintenance and regeneration. CSC-mediated resistance arises through coordinated intrinsic and extrinsic mechanisms. Intrinsically, CSCs employ multiple survival programs, including cellular quiescence, enhanced DNA damage response and repair, ATP-binding cassette transporter-mediated drug efflux, apoptosis evasion, and metabolic reprogramming. Extrinsically, these mechanisms are reinforced through dynamic interactions with the tumor microenvironment (TME), particularly hypoxic and perivascular niches that support stemness and therapeutic tolerance. Importantly, CSCs are increasingly recognized as dynamic cellular states rather than fixed populations and exhibit marked plasticity through reversible transitions between stem-like and non-stem states, frequently mediated by epithelial-mesenchymal transition (EMT). This plasticity promotes intratumoral heterogeneity and replenishes resistant cell populations. In this review, we provide a comprehensive synthesis of the molecular and microenvironmental mechanisms underlying CSC-driven drug resistance and critically discuss emerging therapeutic strategies targeting CSC plasticity, niche interactions, metabolic adaptation, and immune evasion. Collectively, these insights support the development of integrated multi-target therapeutic approaches to improve long-term clinical outcomes.
