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

objectiveEsophageal squamous cell carcinoma (ESCC) is characterized by a high incidence of lymph node metastasis, and prophylactic lymphadenectomy plays a critical role in esophagectomy. However, the optimal extent of lymphadenectomy after neoadjuvant chemotherapy (NAC) remains unclear. We aimed to investigate the extent and significance of lymphadenectomy after NAC by comparing its therapeutic impact with that of upfront esophagectomy.

methodsIn total, 200 consecutive patients who underwent McKeown esophagectomy for ESCC between 2009 and 2021 were eligible. We compared the therapeutic value index (TVI) between patients who underwent esophagectomy after NAC and those who underwent upfront esophagectomy.

results96 (48.0%) patients underwent upfront esophagectomy and 104 (52.0%) patients underwent esophagectomy after NAC. In the upper mediastinum, middle/lower mediastinum, and peri-gastric regions, TVI in the NAC group was greater than that in the upfront group. In contrast, subcarinal lymphadenectomy showed no therapeutic benefit in the NAC group, and supra-pancreatic TVI was lower in the NAC group than in the upfront group (2.4 vs. 7.0). After propensity score matching (PSM), the results were essentially unchanged from those before matching. Subgroup analysis revealed almost no therapeutic benefit in the supra-pancreatic region for upper/middle thoracic tumors or early-stage cancers, whereas a benefit remained for lower thoracic tumors.

conclusionsLymphadenectomy in the upper mediastinum, middle/lower mediastinum, and peri-gastric regions remains important after NAC for ESCC. However, the apparent therapeutic value of subcarinal and supra-pancreatic lymphadenectomy was limited after NAC.
