Exploration of the pattern of lymph node metastasis in esophageal cancer based on membrane anatomy theory.
Article in Thoracic cancer, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveTo analyze the pattern of lymph node metastasis in esophageal cancer based on the theory of membrane anatomy.
methodsA retrospective analysis was conducted on 143 patients who underwent esophageal surgery at the Cancer Hospital of the Chinese Academy of Medical Sciences from March 2021 to March 2022. Lymph node metastasis was observed and categorized according to postoperative T staging. The characteristics and patterns of lymph node metastasis in different regions were observed, and the lymph node metastasis patterns in patients with clinical T3 esophageal cancer were analyzed using membrane anatomy theory.
resultsAmong the 143 patients with esophageal squamous cell carcinoma, 21 were treated with surgery alone, while the rest received preoperative adjuvant therapy. A total of 5456 lymph nodes were cleared from the 143 patients, with 204 positive lymph nodes, resulting in a positive rate of 3.74%. In the thoracic lymph node dissection, the metastatic rates exceeded 5% for the following regions: 106recR (17.36%), 106recL (12.5%), 107 (10.42%), and 108 (5.56%) station. When analyzing the abdominal lymph node metastasis, the metastatic rates exceeded 5% for regions 7 (13.19%), 3a (7.64%), 2 (6.94%), and 1 (6.25%) station. Group analysis of patients with esophageal squamous cell carcinoma before postoperative pathological T3 stage revealed an increasing trend in tumor lymph node metastasis rate with later T staging. Lymph node metastasis in region 106recR can occur early, with a metastasis rate of 18.37% in T1 tumors. Analysis of lymph node metastasis characteristics in 103 patients clinically staged as T3 showed that 3966 lymph nodes were cleared, with 186 positive nodes, resulting in a positive rate of 4.69%. Lymph node metastasis rates were higher in regions 106recL, 106recR, 107, 108, 110, 1, 2, 3a, and 7, all exceeding 5%.
conclusionThe theory of membrane anatomy can effectively explain the pattern of lymph node metastasis in esophageal cancer.
