PrecisionLymphoNet: Advancing Malignant Lymphoma Diagnosis via Ensemble Transfer Learning with CNNs

Area of Science:

• Medical Imaging
• Machine Learning
• Oncology

Background:

• Malignant lymphoma diagnosis is challenging due to diverse subtypes (CLL, FL, MCL).
• Accurate differentiation of these subtypes is crucial for effective treatment strategies.
• Current diagnostic methods face limitations in speed and precision.

Purpose of the Study:

• To develop and evaluate novel transfer learning models for accurate lymphoma subtype classification.
• To compare the performance of ensemble and non-ensemble models in diagnosing CLL, FL, and MCL.
• To demonstrate the potential of deep learning for improving lymphoma diagnostic accuracy.

Main Methods:

• Utilized pre-trained deep learning models (VGG16, VGG19, DenseNet201, InceptionV3, Xception) for feature extraction.
• Implemented a stack-based ensemble approach combining multiple models for enhanced classification.
• Trained and tested models on a multiclass dataset of chronic lymphocytic leukemia, follicular lymphoma, and mantle cell lymphoma images.

Main Results:

• Individual models like DenseNet201, InceptionV3, and Xception achieved over 90% accuracy.
• The proposed stack-based ensemble model, integrating InceptionV3 and Xception, reached an exceptional 99% accuracy.
• The ensemble approach significantly outperformed previous prediction methods for lymphoma diagnosis.

Conclusions:

• Transfer learning, particularly ensemble methods, offers a highly effective strategy for lymphoma subtype diagnosis.
• The developed models demonstrate high feasibility and efficiency for real-world clinical applications.
• This research paves the way for more precise and automated lymphoma diagnostic tools.
