Decoding Sarcoma Drug Resistance: From Molecular Mechanisms to Precision Interventions.
Review in Anti-cancer agents in medicinal chemistry, 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
introductionThis study aims to systematically synthesize current knowledge on the molecular and microenvironmental mechanisms driving sarcoma drug resistance, and to evaluate emerging precision strategies for overcoming these obstacles.
methodsWe conducted a comprehensive literature review (PubMed, Web of Science, Embase; inception- 31 July 2025) using MeSH and free-text terms relating to sarcoma, drug resistance, biomarkers, and precision medicine. Inclusion criteria were peer-reviewed original or review studies in human or pre-clinical sarcoma models reporting resistance mechanisms or counter-strategies. Data were qualitatively categorized by resistance pathways (efflux pumps, DNA repair, apoptosis inhibition, secondary mutations, and immune evasion) and linked to therapeutic countermeasures.
resultsABC transporter over-expression (especially P-gp) and heightened DNA repair via homologous recombination were recurrent chemo-resistance drivers. Targeted-therapy failure was dominated by secondary KIT/PDGFRA or NTRK mutations, bypass signaling (PI3K/AKT ↔ RAS/MAPK), and epithelial- mesenchymal transition. Immune escape occurred through antigen loss, MHC-I down-regulation, adenosine- rich immunosuppressive microenvironments, and T-cell exhaustion (PD-1/CTLA-4 up-regulation). Epigenetic dysregulation (EZH2, HDAC, DNMT) further fostered stem-like survival. Liquid-biopsy ctDNA enabled real-time resistance monitoring. Next-generation TKIs, dual-pathway inhibitors, epigenetic drugs, and rationally designed chemo-immuno combinations showed synergistic activity in pre-clinical and early clinical studies. DISCUSSION: Integrating multi-omics profiling, liquid biopsies, and patient-derived organoids into adaptive trial designs can individualize therapy sequences and delay resistance. Limitations include heterogeneous sarcoma biology, limited clinical validation, and economic barriers to the implementation of precision.
conclusionResistance to drugs in sarcoma is multifactorial and changeable. Nevertheless, fusing mechanistic knowledge with biomarker - guided combination/sequential therapies offers a clear way to improve patient situations.
