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.

Abstract

backgroundRetrospective studies have shown that adjuvant treatment improves survival of patients with stage IIB-III esophageal squamous cell carcinoma, but there is no evidence from prospective trials so far. MATERIALS AND

methodsPatients with pathological stage IIB-III esophageal squamous cell carcinoma were randomly assigned to receive surgery alone (SA), postoperative radiotherapy (PORT), or postoperative concurrent chemoradiotherapy (POCRT). PORT patients received 54 Gy in 27 fractions; the POCRT group received 50.4 Gy in 28 fractions, plus concurrent chemotherapy with paclitaxel (135-150 mg/m

resultsA total of 172 patients were enrolled (SA, n = 54; PORT, n = 54; POCRT, n = 64). The 3-year DFS was significantly better in PORT/POCRT patients than in SA patients (53.8% vs. 36.7%; p = .020); the 3-year OS was also better in PORT/POCRT patients (63.9% vs. 48.0%; p = .025). The 3-year DFS for SA, PORT, and POCRT patients were 36.7%, 50.0%, 57.3%, respectively (p = .048). The 3-year OS for SA, PORT, and POCRT patients were 48.0%, 60.8%, 66.5%, respectively (p = .048).

conclusionPORT/POCRT (especially POCRT) may significantly improve DFS and OS in stage IIB-III esophageal squamous cell carcinoma. IMPLICATIONS FOR PRACTICE: The results of this phase III study indicated that postoperative radiotherapy/postoperative concurrent chemoradiotherapy (PORT/POCRT) could significantly improve disease-free survival and overall survival in stage IIB-III esophageal squamous cell carcinoma compared with surgery alone with acceptable toxicities. In-field and out-of-field recurrences were comparable between the POCRT and PORT groups, which demonstrates the rationality and safety of the radiation field used in this study. The postoperative regimens in this trial might be accepted as standard treatment options for pathological stage IIB-III esophageal cancer. Larger sample size prospective randomized trials to identify the value are warranted.
