A preoperative computed tomography radiomics model to predict disease-free survival in patients with pancreatic neuroendocrine tumors

Eur J EndocrinolPublished Retrospective cohort study

Study context

Population
French patients with surgically resected pancreatic neuroendocrine tumors (pNETs) and available computed tomography (CT) examinations; median age 61 years, 20 men; grade 1 57%, grade 2 32%, grade 3 11%
Participants
37 patients
Exposure
Radiomics index >0.4 vs ≤0.4
Outcome
RFS and OS predicted by preoperative CT radiomics index (Kaplan-Meier)
Methodological detailsobservational, radiomics model, Features extracted with 3D-Slicer® (manual segmentation); LASSO selection trained on Ki67 rate (≤2 or >2); ROC used to select cutoff

Main finding

As reported in the abstract

Median RFS

P = 0.013

Observational data: associations, not effects.

Further findings

No associations between the radiomics index and OS
P = 0.86
