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

purposeLocally advanced esophageal cancers are generally treated with neoadjuvant chemoradiotherapy, followed by surgery in operable candidates. However, even if the patients were diagnosed as operable disease, surgery could not be performed on patients with poor condition or other comorbidity. In this case, definitive chemoradiotherapy (dCRT) is the other option for localized esophageal cancer. Therefore, the purpose of this study was to evaluate the efficacy and clinical prognostic factors for dCRT in locally advanced esophageal cancer. MATERIALS AND

methodsWe conducted a review of patients who received dCRT for locally advanced squamous esophageal cancer from 2004 to 2010, focusing on stages III and IVa. All patients received at least two cycles of platinum-based chemotherapy during radiation, and all tumor burdens were included in the radiation field. The treatment results were analyzed for patterns of failure and prognostic factors associated with survival.

resultsIn total, 63 patients were enrolled in this study. The overall response rate was 84.1%. Relief from dysphagia after dCRT was achieved in 48 patients. The most frequent failure was local recurrence. The median overall survival (OS) was 23.0 months, and the 2-year survival rate was 45.4%. Similar results were observed for elderly study patients. Significant prognostic factors for OS were duration of smoking, high grade of dysphagia (score of 3 or 4), and shorter duration of progression-free and dysphagia-free survival. Maintenance chemotherapy after dCRT did not influence OS. However, "good risk" patients receiving maintenance chemotherapy showed better OS than those who did not receive maintenance chemotherapy (30.4 months vs. 12.0 months, p=0.002).

conclusiondCRT has a major role in improving survival and palliation of dysphagia in inoperable advanced esophageal cancer, even in elderly patients. Maintenance chemotherapy after dCRT may be effective in prolonging survival in "good risk" patients.
