Area of Science:

  • Endocrinology
  • Oncology
  • Data Science

Background:

  • Post-operative tumor progression in non-functioning pituitary neuroendocrine tumors (NF PitNET) is unpredictable.
  • Accurate outcome prediction is crucial for patient management.

Purpose of the Study:

  • To evaluate machine learning (ML) models for predicting post-operative outcomes in NF PitNET patients.
  • To compare ML model performance against traditional statistical methods.

Main Methods:

  • Analysis of data from 383 patients undergoing surgery for NF PitNET.
  • Application of ML models: k-nearest neighbor (KNN), support vector machine (SVM), and decision tree.
  • Comparison with logistic regression for predicting tumor progression.

Main Results:

  • ML models, particularly SVM, demonstrated superior performance in predicting tumor progression compared to logistic regression.
  • Extent of surgical resection was the most significant predictor of progression.
  • Patient age, tumor volume, and radiotherapy use also influenced outcomes.

Conclusions:

  • ML models show significant potential for improving post-operative outcome prediction in NF PitNET.
  • Complete resection was associated with no recurrence, highlighting surgical success.
  • Future research should incorporate multicenter data and advanced imaging for enhanced prediction.
