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

backgroundThe aim of this study was to compare the outcome of patients with adenocarcinoma of the distal esophagus (AEG type I) treated with neoadjuvant chemoradiation or perioperative chemotherapy.

methodsEligible patients from four Austrian centers were selected to conduct a retrospective analysis. All patients treated between January 2007 and October 2017 with chemotherapy according to EOX-protocol (Epirubicin, Oxaliplatin, Xeloda) or chemoradiation according to CROSS-protocol (carboplatin/paclitaxel + RTX 41.4 Gy), before esophagectomy were included. Primary outcomes disease-free survival (DFS) and overall survival (OS) as well as secondary outcomes downstaging of T- or N-stage and achievement of pathological complete response pCR (ypT0N0M0) were analyzed. Data of 119 patients were included.

resultsComplete data was available in 104 patients, 53 patients in the chemoradiation group and 51 patients in the chemotherapy group. The mean number of lymph nodes removed was significantly higher in the EOX group (EOX 29 ± 15.5 vs. CROSS 22 ± 8.8; p < 0.05). Median follow-up in the CROSS group was 17 months (CI 95% 8.8-25.2) and in the EOX group 37 months (CI 95% 26.5-47.5). In the chemotherapy group, the OS rate after half a year, - 1, and 3 years was 92%, 75%, and 51%. After chemoradiation, overall survival after half a year was 85 %, after 1 year 66%, and after 3 years 17%. In the EOX group DFS after ½, - 1, and 3 years was 90%, 73%, and 45%, in the chemoradiation group after half a year 81%, after 1 year 55% and after 3 years 15%. Pathological complete response (pCR) was achieved in 23% of patients after CROSS and in 10% after EOX (p < 0.000).

conclusionsThere seem to be clear advantages for chemoradiation, concerning the major response of the primary tumor, whereas a tendency in favor for chemotherapy is seen in regards to systemic tumor control. Furthermore, the type of neoadjuvant treatment has a significant influence on the number of lymph nodes resected.
