Area of Science:

  • Oncology
  • Medical Artificial Intelligence
  • Surgical Outcomes

Background:

  • Gastric cancer necessitates gastrectomy with lymph node dissection, a procedure with a 10%-20% complication rate.
  • Current surgical methods have limitations in preventing post-gastrectomy complications, including fatalities.

Purpose of the Study:

  • To develop and validate a novel artificial intelligence (AI) model for predicting postoperative complications following radical gastrectomy.
  • To leverage deep learning techniques for early diagnosis of complications in gastric cancer patients.

Main Methods:

  • A deep learning neural network model was constructed using 4000 variables from clinical, surgical, and pathological data.
  • Model parameters were optimized using 70% of patient data, with the remaining 30% used for validation.

Main Results:

  • The AI model achieved a Receiver Operating Characteristic Area Under the Curve (ROC-AUC) of 0.8 for diagnosing complications.
  • The model demonstrated a sensitivity of 81% and specificity of 69% on teaching data, and 50% and 75% on validation data, respectively.

Conclusions:

  • A deep learning-based predictive model for postoperative complications after radical gastrectomy was successfully developed.
  • This AI tool can assist surgeons in accurately predicting the incidence of complications by postoperative day 3.
