A Retrospective Analysis of Incidental Gallbladder Cancer on Post-cholecystectomy Pathological Review.

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 Gallbladder cancer is a rare cancer with a poor prognosis despite all the advances in treatment options and is mostly detected incidentally. In the current literature, re-excision is performed on patients with stage T1b and above, but high mortality rates are still observed. In this study, we aimed to investigate the reasons affecting the prognosis of incidental gallbladder cancer. Methodology Data from 33 patients were retrospectively analyzed. Patient age, sex, preoperative radiologic findings, surgical procedures, margin status, postoperative results with histologic diagnosis, T stage, complications, and mortality were evaluated. Results Of the 33 patients included in the study, 24 (72.7%) were female, nine (27.3%) were male, and the mean age was 66.4 ± 13.4 years. Seventeen (51.5%) patients in our study were aged over 65 years. Age over 65 years was found to have a significant effect on mortality (p = 0.018). In the preoperative ultrasound imaging, 27 (81.8%) patients had gallstones, two (6.1%) patients had gallbladder polyps, 31 (93.9%) had focal or diffuse thickness increases in the gallbladder wall, and nine (27.3%) patients had pericholecystic fluid. The presence of pericholecystic fluid (p = 0.039) and wall thickness (p = 0.006) were found to be associated with mortality. There was perineural invasion and lymphovascular in 17 patients each. Both perineural invasion (p = 0.016) and lymphovascular invasion (p = 0.007) were associated with mortality. Tumor grade was also associated with mortality (p = 0.001). When the prognosis of the patients was evaluated according to the T stage, the increase in the T stage negatively affected the prognosis (p < 0.001). Overall survival was a median of 17 months (95% confidence interval = 10.6-23.3). Conclusions Incidental gallbladder cancer is detected on routine histologic examination of gallbladder specimens after cholecystectomy. Most patients may require re-excision, but the prognosis is still poor in patients who have undergone re-excision. Age >65 years, pericholecystic fluid, T stage, grade, lymphovascular invasion, and perineural invasion had a significant effect on mortality, the presence of which should trigger the option of re-excision to be examined more carefully.
