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

purposeTo compare R0 resection rates and short-term and oncologic outcomes between laparoscopy and open surgery for T4 colon cancer.

methodsPatients with non-metastatic T4 colon cancer (n = 117) underwent treatment either through laparoscopy (n = 51) or open surgery (n = 66). Conversion to open surgery occurred in seven cases (13.7%).

resultsHistory of abdominal surgery (2.0 vs. 12.1%) and emergency operation (2.1 vs. 24.2%) were less frequent in the laparoscopy group. Conversion to open surgery occurred in seven cases (13.7%). Resection of adjacent organs was less frequently performed in the laparoscopy group (27.5 vs. 53.0%, p = .005). The mean operative time (189 vs. 210 min) and rate of 30-day postoperative complications (12 vs. 24%) were similar between the two groups. Shorter time to soft diet (7 vs. 9 days, p = .018) and hospital stay (14 vs. 18 days, p = .044) were observed in the laparoscopy group. T4b tumor was also less frequent in the laparoscopy group (3.9 vs. 18.2%, p = .018), while R0 resection rates were similar between the laparoscopy (96.1%) and open surgery group (95.5%). The mean number of lymph nodes was 22 in the laparoscopy group and 27 in the open surgery group (p = .021). No differences in 3-year overall survival rate (82.5 vs. 75.7%), recurrence-free survival rate (61.9 vs. 63.5%), and local recurrence-free survival rate (89.8 vs. 88.5%) were observed between the groups. Operation time, blood loss, 30-day complication rate, time to diet, duration of hospital stay, R0 resection rate, 3-year overall and local recurrence-free survival rates showed no difference between the converted and open surgery groups.

conclusionsOur results indicate that laparoscopy is a surgically safe and oncologically acceptable approach and thus could be considered for well-selected patients with T4 colon cancer in order to allow faster short-term recovery.
