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

backgroundSeveral studies have reported the efficacy of resection for recurrent lesions. However, they involved a limited number of subjects. This study aimed to identify a subset of patients who benefit from surgical resection of recurrent lesions after curative esophagectomy for esophageal squamous cell carcinoma.

methodsClinicopathological features of 186 patients with esophageal squamous cell carcinoma who underwent surgical treatment for postoperative recurrent lesions at 37 accredited institutions of the Japanese Esophageal Society were evaluated.

resultsThe most common recurrence site was the lymph node (106 cases; 58.6%), followed by the lung (40 cases; 22.1%). Univariate analyses revealed that pN 0-1 at esophagectomy (P = 0.0348), recurrence-free interval of ≥ 550 days (P = 0.0306), R0 resection (P < 0.0001), and absence of severe complications after resection for recurrent lesions (Clavien-Dindo grade < IIIa) (P = 0.0472) were associated with better overall survival after surgical resection. According to multivariate analyses, pN 0-1 (P = 0.0146), lung metastasis (P = 0.0274), recurrence-free interval after curative esophagectomy of ≥ 550 days (P = 0.0266), R0 resection (P = 0.0009), and absence of severe complications after resection for recurrent lesions (Clavien-Dindo grade < IIIa) (P = 0.0420) were independent predictive factors for better overall survival.

conclusionsSurgical resection of recurrent esophageal squamous cell carcinoma lesions is a useful option, especially for cases involving lower pN stage, lung metastasis, long recurrence-free intervals after esophagectomy, and technically resectable lesions. Surgical risks should be minimized as much as possible.
