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

purposeThe purpose of this study is to determine the clinical significance of micrometastases after neoadjuvant chemotherapy (NAC) and the difference in controlling micrometastases using different NAC regimens in resectable advanced esophageal squamous cell carcinoma (ESCC).

methodsWe analyzed patients with ESCC who underwent esophagectomy with lymph node dissection after NAC with Adriamycin + cisplatin + 5-fluorouracil (ACF) or docetaxel + cisplatin + 5-fluorouracil (DCF). Micrometastasis was defined as a single isolated cancer cell or cluster of cancer cells on the cervical, recurrent nerve, or abdominal LNs as shown by immunohistochemical staining with anti-cytokeratin antibody (AE1/AE3). The associations between micrometastases, recurrence, prognosis, and regimen differences were investigated.

resultsOne hundred and one cases (ACF group: 51 cases; DCF group: 50 cases) were analyzed. Micrometastases occurred in 24 patients (23.8%): 17/51 (33.3%) in the ACF group and 7/50 (13.5%) in the DCF group (p = 0.0403). The 5-year recurrence-free survival (RFS) rates for patients without (n = 77) and with (n = 24) micrometastases were 62 and 32%, respectively, (hazard ratio, 2.158; 95% confidence interval, 1.170-3.980; stratified log-rank test, p = 0.0115). A multivariate analysis showed that stage pN1 or higher and micrometastases were significant risk factors affecting RFS.

conclusionIn resectable advanced ESCC, controlling micrometastases in the LNs after NAC varied by regimen and may be associated with preventing ESCC recurrence.
