Predicting Cancer in Pancreatic Cystic Lesions Through Artificial Intelligence

April 30, 2025 updated by: Centre Hospitalier Universitaire de Nice

Deep Learning for Malignant Degeneration Prediction of Pancreatic Cystic Lesions - Beyond High-risk Stigmata

This international, multicenter retrospective study aims to develop a deep learning (DL)-based predictive model to identify malignant transformation in pancreatic cystic lesions, improving upon current clinical guidelines. The model will integrate clinical, biochemical, and multimodal imaging data. Several 3D convolutional neural networks will be trained using advanced preprocessing, data augmentation, and hybrid fusion techniques. Model performance will be compared to that of existing international guidelines. The study involves no additional procedures for patients and adheres to strict data anonymization and privacy regulations.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

Patients who underwent pancreatic surgery for pancreatic cystic lesions, in the absence of preoperative evidence of cancer. Indication of surgery must be based on one or more current guidelines concerning pancreatic cystic lesions management.

Inclusion Criteria:

  • Patients diagnosed with PCL(s ) who underwent pancreatic surgery in one of the participant centers. Surgical indication must adhere to at least one of current guidelines on PCLs management (6), based on clinical, biochemical, and radiological (MR and/or EUS) features.
  • Pancreatic surgery B83performed for supposed increased risk of cyst(s) malignant degeneration following current guidelines on PCLs management (6).
  • Absence of clinical, biochemical, radiological, and anatomopathological evidence of pancreatic cancer at pancreatic surgery.
  • Non-opposition to the anonymous data processing by the included patients.

Exclusion Criteria:

  • Patients presenting with evidence of pancreatic cancer at surgery.
  • PCL(s) diagnosis and treatment performed without one between EUS and pancreatic MR. surgery performed in the absence of the criteria proposed by current guidelines.
  • Unavailability of both preoperative EUS and pancreatic MR data.
  • Unavailability of postoperative PCL(s) anatomopathological analysis results.
  • SBO diagnosis performed without CT-scan.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Prediction of malignant degeneration of pancreatic cystics lesions
Time Frame: 90 days from patients hospital discharge.
Predict the presence of malignant degeneration (defined as: high grade dysplasia, in situ PADC, or T1 PADC) in pancreatic cystic lesion(s) using artificial intelligence model based on clinical, biochemical, and radiological features. This will be measured through Area Under the Receiver Operator Characteristic curve (AUROC) assesment. AUROC varies between 0.5 and 1, corresponding to no class separation capacity and full class separation capacity, respectively.
90 days from patients hospital discharge.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Accuracy of performance evaluation
Time Frame: 90 days from patients hospital discharge.
the number of true positives and true negatives among all predictions. It varies between 0 (no correct prediction) to 1 (full correct predictions).
90 days from patients hospital discharge.
Precision of performance evaluation
Time Frame: 90 days from patients hospital discharge.
The number of true positives divided by all the positive predictions (true positives and false positives). It varies between 0 (no correct prediction) to 1 (full correct predictions).
90 days from patients hospital discharge.
Recall of performance evaluation
Time Frame: 90 days from patients hospital discharge.
The number of true positives divided by the actual positive instances in the dataset (true positives and false negatives). It varies between 0 (no correct prediction) to 1 (full correct predictions).
90 days from patients hospital discharge.
Balanced accuracy
Time Frame: 90 days from patients hospital discharge.
the aritmethic mean of sensitivity and specificity. It varies between 0 (no correct prediction) to 1 (full correct predictions).
90 days from patients hospital discharge.
F1-score
Time Frame: 90 days from patients hospital discharge.
It combines precision and recall. It ranges from 0-100%, and a higher F1 score denotes a better quality classifier.
90 days from patients hospital discharge.
Confusion matrix
Time Frame: 90 days from patients hospital discharge.
A visual representation of true positives, false positives, true negatives, and false negatives. It is depicted through a table.
90 days from patients hospital discharge.
Log-loss
Time Frame: 90 days from patients hospital discharge.
It indicates how close the prediction probability is to the corresponding actual/true value (0 or 1 in case of binary classification). The more the predicted probability diverges from the actual value, the higher is the log-loss value.
90 days from patients hospital discharge.
Cohen's Kappa
Time Frame: 90 days from patients hospital discharge.
A metric used to measure the level of agreement between two raters which can be a useful tool to gauge the performance of a classification model. It accounts for the fact that the raters may happen to agree on some items purely by chance. It varies between 0 (no correct prediction) to 1 (full correct predictions).
90 days from patients hospital discharge.
