Impact of Symptom Phenotype on Surgical Quality and Survival in Small-Bowel Neuroendocrine Tumours: A Quality Metrics Analysis.
Article in Journal of surgical oncology, 2026. 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
backgroundThere is debate regarding the optimal management of small-bowel neuroendocrine tumours (SBNETs), particularly concerning upfront resection in various clinical presentations. While symptom phenotypes are known to influence survival, their impact on technical surgical quality, especially in the emergency setting, remains poorly defined. This study evaluates whether symptom phenotype compromises the delivery of guideline-concordant surgical care.
methodsA retrospective analysis of 108 consecutive SBNET resections (2000-2023) at a specialized tertiary centre was performed. Patients were stratified into four phenotypes: obstructive/perforation (n = 54), carcinoid syndrome (22), asymptomatic/incidental (22), and other symptoms (9). Operative metrics, including lymph-node harvest (LNY) and margin status (R0/R1), were compared alongside overall survival (OS).
resultsSymptom phenotype was a predictor of operative urgency and approach. Obstructive cases required emergency surgery in 50% of instances compared to ≤ 11% in all other groups (p < 0.001). Synchronous liver metastases were most prevalent in the carcinoid syndrome phenotype (50%) and lowest in the asymptomatic group (5%) (p = 0.002). Despite these disparities in presentation and urgency, technical quality markers were uniform across all groups: median LNY ranged from 10 to 13 (p = 0.426), R1/R2 margin rates were statistically similar (p = 0.290), and median length of stay was 8 days for all cohorts (p = 0.311). Multivariable analysis identified the asymptomatic phenotype as independently protective for OS (HR 0.42, p = 0.032), while liver metastasis was the strongest adverse prognostic factor (HR 3.25, p < 0.001).
conclusionsSymptom phenotype dictates operative urgency and reflects disease burden but does not compromise the technical standards of surgery in a specialized unit. These findings suggest that high-quality, guideline-concordant lymphadenectomy is achievable even in emergency obstructive presentations, and correspondingly, access to specialized surgical oncology expertise may be sought even in obstructed patients to ensure technical quality is maintained.
