Value of separate tumor base biopsy in transurethral resection of bladder tumors.
Article in Central European journal of urology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionThe aim of our study was to evaluate whether a biopsy from the tumor base after transurethral resection of bladder tumor (TURBT) has an impact on subsequent management of patients with bladder tumors. While tumor base biopsy at the completion of TURBT is a common practice, there is no definition of its role within the major international professional guidelines. MATERIAL AND
methodsWe retrospectively reviewed the records of consecutive patients undergoing TURBT between 2015 and 2019 at our institution. We recorded demographic and tumor characteristics of initial TURBT, tumor base biopsy and restaging TURBT pathology outcomes. The pathologic outcomes were correlated to assess the additional value of a separate tumor base biopsy.
resultsA total of 532 patients underwent TURBT. A separate tumor base biopsy after completion of TURBT was performed in 154 patients. The mean patient's age was 72.8 ±11.7 years (range 48-94) and 119 (77.2%) were men. In 40 patients (25.9%) muscle was absent in the pathological specimen of the tumor resection. Muscle was present in all but 6 (3.9%) tumor base biopsies. Of the 33 patients who underwent repeated transurethral resection for pT1 tumors, 2 had residual low-grade pTa, 1 had residual high-grade pT1, and 3 patients were upstaged to pT2.
conclusionsAlthough tumor base biopsy at the completion of TURBT is a common practice, our analysis fails to demonstrate any tangible benefit in the staging of bladder tumors. In our experience tumor base biopsy did not change the management in patients with superficial or muscle invasive disease.
