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

backgroundEsophageal cancer is one of the leading types of cancer, and it is a particularly deadly form of malignancy. TNM classification is the most common staging system, but it has been reported that prognosis is not reflected adequately by this classification. The purpose of this study was to clarify independent prognostic factors in esophageal squamous cell carcinoma (ESCC), a dominant type of esophageal cancer in Japan, to broaden the staging system to improve its predictive value. Thus staging could be expanded to make the prognosis a valuable clinical tool, and to improve knowledge of the biological traits of advanced ESCC.

methodsThe present study included 121 patients with advanced ESCC (stage II to IVA) treated by esophagectomy between 1990 and 2003 at the Kitasato University Higashi Hospital.

resultsUnivariate prognostic analysis of the disease-specific survival revealed that TNM stage (p < 0.0001), lymph node metastasis density over 10% (ND10; p < 0.0001), R-category (p = 0.003), intramural metastasis within the esophagus (IM; p = 0.009), growth pattern (p = 0.01), and size of tumor (p = 0.02) were significantly associated with a poor outcome in advanced ESCC. Multivariate analysis confirmed that growth pattern (p = 0.02, HR = 3.1) and ND10 (p = 0.02, HR = 2.0) were finally remnant prognostic factors independent of TNM stage. Growth pattern was prominent in stage II, whereas ND10 was directly proportional to stage progression and characteristics to stage IV disease. Interestingly, ND20, the most malignant phenotype of ESCC, was the only prognostic determinant, even in stage IV disease.

conclusionsFrom the present study, we concluded that progression of lymph node density is characteristic of a life-threatening phenotype of advanced ESCC, and it should be employed as a therapeutic target to improve patient survival. Growth pattern is an alternative target characteristic of less advanced ESCC. Both of these parameters may be applied as useful clinical tools in the management of patients with advanced esophageal cancer.
