Comparison of the Oncologic Outcomes for Patients with Middle to Lower Esophageal Squamous Cell Carcinoma Undergoing Surgical Treatment Using the Ivor-Lewis or McKeown Operation.
Article in Annals of surgical oncology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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 upper mediastinum is the most common metastatic site of esophageal squamous cell carcinoma (ESCC), and complete dissection of this region is important for oncologic reasons. This study aimed to compare the oncologic outcomes and completeness of upper mediastinal dissection for ESCC patients undergoing the Ivor-Lewis (IL) or McKeown (MK) operations.
methodsBetween 2013 and 2018, 680 patients (IL, 433; MK, 247) underwent upfront esophagectomy with two-field lymph node (LN) dissection for mid-to-lower ESCCs. Propensity score-matching (1:1 ratio) was performed to minimize the effects of confounding factors.
resultsThe mean age was 64.5 ± 8.8 years, and 635 (93.4%) of the patients were male. The median follow-up period was 71.66 months (interquartile range [IQR], 59.60-91.04 months). The IL group had a higher mean age, lower body mass index, higher proportion of advanced T and N, and higher adjuvant therapy rates, but these differences were well-balanced after propensity score-matching. The mean number of dissected LNs at the mediastinum and at the right recurrent laryngeal nerve (RLN) were similar between the two groups after matching, whereas the IL group exhibited a slightly greater number of dissected LNs at the left RLN. Among the matched patients, the IL and MK groups exhibited similar 5-year overall survival (OS: 75.1% vs 78.0%; p = 0.368). The multivariate model showed no differences in OS, disease-free survival, or recurrence-free survival for locoregional, upper mediastinum, or neck between the two groups.
conclusionsThis study suggests that both the IL and MK operations are oncologically feasible for patients with mid-to-lower ESCC.
