Treatment and survival of non-metastatic small cell carcinoma of the bladder from multiple centers in China.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Small cell carcinoma of the bladder (SCCB) is a rare, highly malignant neuroendocrine tumor. This study attempted to analyze tumor characteristics, treatments and clinical outcomes in China. We conducted a retrospective analysis of patients diagnosed with non-metastatic SCCB at multi-institutions between January 2007 and January 2022. The Kaplan-Meier method was used to calculate survival. A total of 20 patients were included. 10 had localized disease (T1-2N0), and 10 had locally advanced disease (≥ T3 or N+). 13 received local treatment (partial cystectomy or transurethral resection of the bladder tumor) and 7 received radical treatment (radical cystectomy or radiotherapy). A total of 18 patients (90%) received chemotherapy (CT), either neoadjuvant CT (n = 5) or adjuvant CT (n = 13). The median OS for the receiving local treatment was 65.3 months (95% CI 0 to 138 months) and the corresponding 1-year, 2-year, and 3-year OS was 77%, 54%, and 54%, respectively. The median OS for the receiving radical treatment was not reached and the corresponding 1-year, 2-year, and 3-year OS was 100%, 100%, and 75%, respectively. The median PFS for receiving local treatment was 13.8 months (95% CI 9.3 to 18.3 months) and the corresponding 1-year, 2-year, and 3-year PFS was 46%, 31%, and 31%, respectively. The median PFS for the receiving radical treatment was not reached and the corresponding 1-year, 2-year, and 3-year PFS was 83%, 56%, and 56%, respectively. This study reported the largest cohort of non-metastatic SCCB among Chinese population. Given its metastatic potential, CT remained an essential part of the treatment. The survival outcomes of radical cystectomy and RT in non-metastatic SCCB were encouraging.
