University of Toronto researchers found that large language models (LLMs) such as DeepSeek V3 and GPT-4o offer promising support for radiology decision-making in pancreatic cancer when their recommendations cite guideline sources.
Key Details
- 1LLMs were tested for generating NCCN-compliant management plans for 328 pancreatic ductal adenocarcinoma (PDAC) cases.
- 2DeepSeek V3 had a 100% completion rate and 1.5% discordance; GPT-4o had a 96.3% completion rate and 8.8% discordance, a statistically significant difference.
- 3Both LLMs had high (>91%) category-specific concordance, though DeepSeek outperformed GPT-4o—except GPT-4o had 86% for locally advanced nonresectable cancer.
- 4Radiologist review flagged occasional inaccurate recommendations, including misclassification of tumor resectability and overtreatment.
- 5Researchers emphasized that LLM explainability and the ability to cite guidelines are key for clinical trust and workflow integration.
