Special Issue Information

Dear Colleagues,

Artificial intelligence (AI) and machine learning (ML) are redefining cancer research by enabling earlier detection, more accurate diagnosis, and increasingly personalized treatment strategies. As cancer rates continue to rise worldwide, the ability of AI systems to analyze complex imaging, molecular, and clinical datasets at scale offers unprecedented opportunities to accelerate discovery and improve outcomes across the cancer care continuum.

Recent advances in deep learning architectures, specialized computing hardware, and multimodal datasets have driven rapid progress. Convolutional neural networks have achieved high accuracy in tumor detection, segmentation, and grading across radiology and digital pathology. Transformers now facilitate sophisticated analyses of genomic sequences, clinical narratives, and integrated datasets, while generative adversarial networks support data augmentation and modeling of rare cancer presentations. Collectively, these methods are enhancing early cancer detection, reducing diagnostic variability, and improving efficiency in clinical workflows.

AI is also reshaping precision oncology. Multimodal AI models that integrate imaging, histopathology, genomics, and clinical data enable more refined prognostic assessment, biomarker discovery, and therapy response prediction. AI-driven tools are increasingly informing personalized treatment planning, supporting real-time disease monitoring, and accelerating drug discovery through automated target identification and candidate screening.

At the same time, emerging infrastructures such as federated learning and edge computing are addressing key challenges related to data privacy and scalability by enabling decentralized model training. Yet significant barriers remain, including data quality limitations, annotation burden, model interpretability, regulatory concerns, and inequitable access to AI technologies. Overcoming these challenges is essential for responsible clinical translation.

This Special Issue invites original research articles and comprehensive reviews that investigate, develop, or critically assess AI and ML applications in cancer research. Topics of interest include, but are not limited to, the following:

  • Early cancer detection, including screening algorithms and radiomic or liquid biopsy-based approaches;
  • Diagnostic support systems that leverage imaging, pathology, or multimodal datasets;
  • Prognostic and predictive modeling for risk stratification, treatment response, and survival outcomes;
  • AI-driven treatment planning, decision support tools, and personalized therapeutic strategies;
  • Methodological innovations, such as multimodal learning, explainable AI, integration of large-scale omics data, federated learning, or real-world validation frameworks.

By showcasing diverse perspectives and cutting-edge methodologies, this Special Issue aims to stimulate meaningful dialogue within the oncology and data science communities. Ultimately, it seeks to highlight where AI and ML can most effectively contribute to advancing cancer research and improving patient outcomes in the years ahead.

Background/Objectives: Early and complete (R0) surgical resection is essential for optimal outcomes in pancreatic cancer. Optical coherence tomography (OCT) combined with artificial intelligence (AI) may offer real-time intraoperative guidance, potentially reducing reliance on frozen sections. This ex vivo study evaluated convolutional neural networks (CNNs) for distinguishing pancreatic ductal adenocarcinoma (PDAC) from normal pancreatic tissue in OCT images obtained ex vivo. Methods: Between October 2020 and April 2021, OCT scans were obtained from resected pancreatic specimens of 27 adult patients. Tumor and adjacent normal tissue were imaged using a 1310 nm OCT system, followed by histopathological confirmation. A total of 25 PDAC and 30 non-malignant scans were preprocessed and analyzed using cross-validated CNN models (ResNet50, DenseNet121, and MobileNetV2) with both 2D and 3D inputs. Results: Using five-fold stratified cross-validation on 9040 2D and 3000 3D samples (224 px resolution), the 3D DenseNet121 model achieved the highest performance, with an F1-score of 0.74, sensitivity of 72%, and specificity of 81%. Other architectures demonstrated comparable results. Conclusions: AI-assisted OCT can accurately differentiate PDAC from normal pancreatic tissue ex vivo, supporting its potential as a rapid intraoperative diagnostic adjunct. Further studies are warranted to assess its in vivo performance and utility in evaluating resection margins. Full article
