In a new study published in the journal AI in Precision Oncology, Nikhil Thaker, from Capital Health and Bayta Systems, and co-authors, evaluated the performance of various LLMs, including OpenAI’s GPT-3.5-turbo, GPT-4, GPT-4-turbo, Meta’s Llama-2 models, and Google’s PaLM-2-text-bison. The LLMs were given an exam including 300 questions, and the answers were compared to Radiation Oncology trainee performance.
The results showed that OpenAI’s GPT-4-turbo had the best performance, with 74.2% correct answers, and all three Llama-2 models under-performed. The LLMs tended to excel in the area of statistics, but to underperform in clinical areas, with the exception of GPT-turbo, which performed comparably to upper-level radiation oncology trainees and superiorly to lower-level trainees.
“Future research will need to evaluate the performance of models that are fine-tune trained in clinical oncology,” concluded the investigators. “This study also underscores the need for rigorous validation of LLM-generated information against established medical literature and expert consensus, necessitating expert oversight in their application in medical education and practice.”
“The study highlights the potential of generative AI to revolutionize radiation oncology education and practice. OpenAI’s GPT-4-turbo demonstrates that AI can complement medical training, suggesting a future where AI aids in improving patient outcomes. It’s essential, though, to validate these technologies rigorously and involve experts to ensure their reliable and effective use in health care,” says Douglas Flora, MD, Editor-in-Chief of AI in Precision Oncology.
