Gemcitabine-Based Bladder Preservation in BCG-Unresponsive High-Risk NMIBC: Evidence, Limitations, and Clinical Positioning.
Review in Biomedicines, 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
Bacillus Calmette-Guérin (BCG)-unresponsive non-muscle-invasive bladder cancer (NMIBC) is a high-risk disease state for which early radical cystectomy remains the guideline-supported oncologic reference in surgically fit patients. Bladder-sparing therapy is necessary for patients ineligible for or declining cystectomy, but it is a preference-sensitive trade-off rather than an equivalent alternative: failure may permit high-grade recurrence, progression, and loss of a curative window. This targeted narrative review synthesizes the evidence for intravesical gemcitabine monotherapy, sequential gemcitabine-docetaxel, and the sustained-release gemcitabine intravesical system TAR-200/INLEXZO, updated through 4 August 2026. Because the review is not systematic and the evidence is dominated by single-arm and retrospective studies, cross-study comparisons are descriptive and establish neither superiority nor equivalence; many gemcitabine studies enrolled mixed BCG-failure cohorts that do not satisfy the contemporary definition. Gemcitabine monotherapy is active but shows declining disease control over time. Sequential gemcitabine-docetaxel has accumulated substantial multicenter observational experience, yet a 2026 retrospective comparison did not demonstrate improved high-grade recurrence-free survival over gemcitabine alone. TAR-200 achieved a centrally confirmed complete response at any time in 82.4% of patients, with a median duration of response of 25.8 months in the single-arm phase 2b SunRISe-1 study and is approved in the United States as INLEXZO for BCG-unresponsive carcinoma in situ with or without papillary tumors; no approved agent holds a papillary-only indication. Comparative patient-reported outcome evidence remains limited, and molecular markers, urinary tumor DNA and transcriptomic subtypes remain investigational rather than validated selection tools. Bladder-sparing treatment should therefore be phenotype- and label-aware, time-limited, and coupled to intensive surveillance with predefined triggers for cystectomy.
