Perioperative predictors of biochemical remission in acromegaly: a predictive modeling study

PituitaryPublished Retrospective cohort study

Authors' conclusion

Predictive modeling may help estimate biochemical remission after surgery for acromegaly.

Study context

Population
Patients with acromegaly who underwent endoscopic endonasal transsphenoidal resection of GH-secreting primary pituitary adenomas, January 2018 to January 2025
Participants
86 patients
Outcome
Biochemical remission after transsphenoidal resection
Methodological detailspredictive modeling, machine learning, random training/test split, Missing data addressed by median and KNN imputation, Five ML models (GBM, RF, GLMNET, KNN, Nnet) trained with exhaustive feature subset selection, evaluated by AUROC and accuracy

Remission associated with lower Knosp grade
p < 0.0001
Remission associated with dense CAM 5.2 staining
p = 0.037
Best model (RF, 4 features: gender, tumor shape, extent of resection, CAM 5.2) accuracy, test set
0.8235
Best model (RF) AUROC, test set
