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

backgroundThe surgical indications for liver metastasis from bile duct cancer remain contentious, because surgery is generally thought unlikely to improve survival. However, recent reports show that long-term survival has been achieved with liver resection of metastasis from recurrent bile duct cancer in selected patients.

methodsLiver resection for liver metastasis from bile duct cancer was proposed only when the following criteria were met: liver-only metastasis, a solitary tumor, and no increase in the number of lesions during 3 months of observation. This study aimed to validate our criteria and to analyze which factors impact on survival.

resultBetween 2003 and 2017, 164 patients underwent pathologically curative resection for bile duct cancer. Recurrence developed in 98 of these patients, as liver-only metastasis in 25. Eleven of these 25 patients underwent liver resection (liver resection group), and 14 did not (non-liver resection group). The median overall survival was longer in the liver resection group than in all the patients (44 months vs. 17.8 months, respectively p = 0.040). The median overall survival was better in the liver resection group than in the non-liver resection group (44 months vs. 19.9 months, p = 0.012). The disease-free interval was also significantly longer in the liver resection group than in the non-liver resection group [22 months (range; 4-34 months) vs. 3 months (2-11), p < 0.001].

conclusionPotentially, metachronous solitary liver metastasis from bile duct cancer is an indication for liver resection when the patient has had a long disease-free interval. Observation for 3 months from first detection of metastasis may optimize the selection for this surgery.
