The prognostic impact of tumor necrosis in non-muscle invasive bladder cancer.

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
objectiveWe aimed to investigate the impact of tumor necrosis in non-muscle invasive bladder cancer on patients' recurrence and progression rates and survival outcomes.
methodsThis study was conducted retrospectively in a single tertiary center in Turkey. Medical records of patients who underwent transurethral resection of the bladder tumor between January 2016 and January 2021 were reviewed. Patients with pTa and pT1 non-muscle invasive bladder cancer who had undergone complete resection were included in our study. All pathological specimens were reevaluated for the presence of tumor necrosis.
resultsA total of 287 patients (244 males and 43 females) were included in our study. Of them, 33 (11.5%) patients had tumor necrosis. The rates of multiple and large tumors (>3 cm) were higher in patients with tumor necrosis (p=0.002 and p<0.001, respectively). Tumor necrosis was associated with higher rates of pT1 diseases (p<0.001), high-grade tumors (p<0.001), and the presence of lymphovascular invasion (p=0.007). The mean recurrence-free survival of patients with tumor necrosis was 42.3 (4.6) months, and the recurrence-free survival of patients without tumor necrosis was 43.5 (1.8) months (p=0.720). The mean progression-free survival of patients with tumor necrosis was 43.1 (4.6) months, and the progression-free survival of patients without tumor necrosis was 58.4 (0.9) months. In log-rank analysis, there was a statistically significant difference between patients with and without tumor necrosis in terms of progression-free survival (p<0.001).
conclusionIn this study, we demonstrated that patients with non-muscle invasive bladder cancer and tumor necrosis in pathological specimens have shorter progression-free survival and more adverse pathological features.
