Clinicopathological Factors Affecting Stomach Preservation Following Laparoscopic Sentinel Node Navigation Surgery in Patients with Early Gastric Cancer: A Secondary Analysis of the Multicenter Randomized Phase III SENORITA Trial.
Trial report in Annals of surgical oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 SENORITA phase III trial demonstrated the effectiveness of laparoscopic sentinel node navigation surgery (LSNNS) in preserving stomach function for patients with early gastric cancer (EGC), although some patients experienced surgical failure or recurrence. The purpose of this study was to analyze patients' clinicopathologic features from the SENORITA trial who were allocated to LSNNS with stomach-preserving surgery but ultimately did not preserve stomach or experienced recurrence. PATIENTS AND
methodsPatients were categorized into two groups: the failure group (stomach preservation failure or cancer recurrence after LSNNS) and the success group (stomach preservation without recurrence following LSNNS). This study analyzed the detailed clinicopathologic characteristics of patients in the failure group from the SENORITA trial.
resultsAmong 258 patients who underwent LSNNS, 193 patients (74.8%) achieved stomach preservation, while 65 patients (25.2%) failed to preserve. Intraoperative failure was the most common cause of unsuccessful stomach preservation, occurring in 35 of 65 cases (53.8%). Advanced pathological TNM stage was the only independent risk factor by multivariate analysis, with stage IB and IIA patients showing 5.9- and 45.0-fold higher failure risks. The main causes of failure included sentinel basin detection failure, metastatic lymph nodes, positive tumors at resection margins, and complications. The failure group also included five cases of gastric cancer recurrence following LSNNS.
conclusionAccurate preoperative staging and patient selection are crucial for optimizing LSNNS outcomes. Ensuring precise resection with an adequate number of harvested sentinel basin nodes is essential to succeed the stomach-preserving surgery.
