A Retrospective Study of the Usefulness of Partial Cystectomy for Advanced Colorectal Cancer With Bladder Invasion.

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
Background and aim Bladder invasion in colorectal cancer often necessitates total pelvic exenteration (TPE), a highly radical procedure that offers excellent curability but significantly impairs postoperative quality of life (QoL), especially due to urinary diversion. Although TPE is considered the standard approach, partial cystectomy (PC) may be a feasible option in selected patients. Oncological curability and satisfactory QoL may be achieved with appropriate patient selection. This study aimed to evaluate short-term outcomes and voiding-related QoL in patients with colorectal cancer and bladder invasion who underwent either PC or TPE at a single institution. Methods This retrospective study included patients diagnosed with colorectal cancer and bladder invasion between May 2011 and February 2023 who underwent TPE or PC. Perioperative factors such as duration of surgery, blood loss, hospital stay, pathological outcomes, and short-term results were compared. In the PC group, postoperative urinary function was assessed using the Overactive Bladder Symptom Score (OABSS), International Prostate Symptom Score (IPSS), and IPSS-QoL. Results Twenty-two patients were included in this study, with eight and 14 patients in the PC and TPE groups, respectively. The duration of surgery and blood loss (p<0.001 and p=0.012, respectively) were lower in the PC group. Pathological curability and recurrence rates were not significantly different. In the PC group, the median pre- and postoperative IPSSs were 1 and 6, respectively; IPSS-QoL was 3.5 postoperatively. The median OABSS increased from 0.5 to 3.5. Median increases in IPSS and OABSS were 3 and 2, respectively. Conclusion With appropriate patient selection, PC may provide oncological outcomes comparable to those of TPE while better preserving postoperative QoL in patients with colorectal cancer and bladder invasion.
