Details of out-field regional recurrence after involved-field irradiation with concurrent chemotherapy for locally advanced esophageal squamous cell carcinoma.
Article in OncoTargets and therapy, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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 purpose of this study was to describe the patterns of out-field regional recurrence after involved-field irradiation (IFI) in definitive concurrent chemoradiotherapy (CCRT) for locally advanced esophageal squamous cell carcinoma (LA-ESCC) and identify the possible risk factors. PATIENTS AND
methodsEighty patients with LA-ESCC who received CCRT with IFI between January 2003 and January 2009 at the Shandong Cancer Hospital were recruited and analyzed. Imaging scans demonstrating first sites of failure were compared with original computed tomography-based radiation treatment plans, and failure patterns were defined as in-field, outfield regional (failures in initially uninvolved regional nodes), and distant failures.
resultsAfter a median follow-up time of 52.6 months, 24 patients had evidence of out-field regional failure, 43 patients had evidence of in-field failure, and 33 patients had the evidence of distant failure. Multivariate analysis revealed that out-field regional failure was associated with clinical tumor status (T4 vs T1-3, odds ratio [OR] =6.547, P=0.002), tumor length (>8 cm vs ≤8 cm, OR =4.130, P=0.036), response to CCRT (complete response vs no complete response, OR =2.646, P=0.035), and in-field failure (no in-field failure vs in-field failure, OR =1.32, P=0.016). Survival analyses indicated that, compared to in-field failure or distant failure alone group, out-field regional failure alone group tended to have longer overall (P=0.006) and progression-free survival (P=0.164).
conclusionOur data suggested that the predominant failure pattern after IFI was not out-field regional failure, which also did not influence survival significantly, and that out-field regional failure did not shorten the time to disease recurrence, which also did not influence survival significantly. In addition, out-field regional failure was likely to appear later than in-field and distant failures. The relatively advanced local disease followed by poor local control and distant metastases contributed more to the poor outcome of LA-ESCC. Further prospective studies are needed to verify the findings of this study.
