Laparoscopy-assisted colectomy as an Oncologically safe alternative for patients with stage T4 Colon Cancer: a propensity-matched cohort study.
Article in BMC cancer, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundIt is still controversial whether laparoscopy-assisted colectomy (LAC) is suitable for patients with stage T4 colon cancer. This study aimed to compare the short- and long-term outcomes of LAC and open colectomy (OC) for patients with pathologic T4 colon cancer.
methodsData of eligible patients with colon cancer in our institution from March 2004 to September 2014 were retrospectively reviewed. The patients were followed up to September 2016. Propensity score matching was performed to control the bias.
resultsTwo hundred and forty two patients were selected by propensity score matching, with 121 patients in the LAC group and 121 in the OC group. Mean operating time and rate of intraoperative blood transfusion were similar between two groups. In LAC group, shorter time to first flatus and first liquid intake were observed in patients with pT4b stage disease, but not for patients with pT4a stage disease. Less blood loss and shorter length of postoperative hospital stay were examined in LAC group, including pT4a and pT4b stages. Conversion was required in 9.1% (11 out of 121) cases. DFS and OS were similar between LAC and OC groups. The 5-year DFS rate was 64.2% for pT4a stage and 35.5% for pT4b stage in LAC group, and 62.9% and 33.7% in OC group for pT4a (p = 0.374) and pT4b (p = 0.385) stage respectively. For 5-year OS rates, two groups did not differ in pT4a stage (LAC 69.2% vs. OC 66.0%, p = 0.151) and pT4b stage (LAC 37.5% vs. OC 38.1%, p = 0.510).
conclusionsLaparoscopic colectomy appears to be safe for selected patients with pT4 colon cancer in centres with expertise in minimally invasive surgery.
