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

objectiveTo evaluate prognostic factors and tumor staging in patients after esophagectomy for cancer. SUMMARY BACKGROUND DATA: Several reports have questioned the appropriateness of the sixth edition of the International Union Against Cancer (UICC) TNM guidelines for staging esophageal cancer. Additional pathologic characteristics, besides the 3 basic facets of anatomic spread (tumor, node, metastases), might also have prognostic value.

methodsAll patients who underwent resection of the esophagus for carcinoma between January 1995 and March 2003 were extracted from a prospective database. Univariate and multivariate analysis was performed to identify prognostic factors for survival. The goodness of fit and accuracy of 3 staging models (UICC-TNM, Korst classification, Rice classification) predicting survival were assessed.

resultsA total of 292 patients (mean age, 63 years) underwent esophagectomy. The 5-year overall survival rate was 29% (median, 21 months). pT-, pN-, pm-stage, and radicality of the resection were independent prognostic factors. Subdivision of T1 tumors into mucosal and submucosal showed significant differences in 5-year survival between both groups: 90% versus 47%, respectively (P = 0.01). Subdivision of pN-stage into 3 groups based on the number of positive nodes (0, 1-2, and >3 nodes positive) or the lymph node ratio (0, 0.01-0.2, and >0.2) also refined staging (P = 0.001 and P < 0.001, respectively). The current subclassification of M1 (M1a and M1b) is not warranted (P = 0.41). The staging model of Rice was more accurate than the UICC-TNM classification in predicting survival.

conclusionThis study supports the view that the current (6th edition) UICC-TNM staging model for esophageal cancer needs to be revised.
