1 · What the graph read from it

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.

2 · The registry

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

backgroundRectal cancer is frequent in Germany and worldwide. Several studies have assessed laparoscopic surgery as a treatment option and most have shown favorable results. However, long-term oncologic safety remains a controversial issue.

methodsThe current dataset derives from 30 clinical cancer registries in Germany and includes 16,378 patients diagnosed with rectal cancer between 2007 and 2016. Outcomes were 90-day mortality, overall survival (OS), local recurrence-free survival (RFS) and relative survival of patients treated with either open or laparoscopic surgery. Multivariable logistic regression was used to evaluate factors that affected the probability of a patient undergoing laparoscopic surgery as well as to evaluate short-term mortality. OS and RFS were analyzed by Kaplan-Meier plots and multivariable Cox regression conducted separately for UICC stages I-III, tumor location, and sex as well as by propensity score matching followed by univariable and multivariable survival analysis.

resultsOf 16,378 patients, 4540 (27.7%) underwent laparoscopic surgery, a trend which increased during the observation period. Patients undergoing laparoscopy attained better results for 90-day mortality (odds ratio, OR 0.658, 95% confidence interval, CI 0.526-0.822). The 5-year OS rate in the laparoscopic group was 82.6%, vs. 76.6% in the open surgery group, with a hazard ratio (HR) of 0.819 in multivariable Cox regression (95% CI 0.747-0.899, p < 0.001). The laparoscopic group showed a better 5-year RFS, with 81.8 vs. 74.3% and HR 0.770 (95% CI 0.705-0.842, p < 0.001). The 5-year relative survival rates were also in favor of laparoscopy, with 93.1 vs. 88.4% (p = 0.012).

conclusionLaparoscopic surgery for rectal cancer can be performed safely and, according to this study, is associated with an oncological outcome superior to that of the open procedure. Therefore, in the absence of individual contraindications, it should be considered as a standard approach.
