A study recently published in the Radiology journal showcased the remarkable performance of artificial intelligence (AI) algorithms in predicting the five-year risk of breast cancer, surpassing the accuracy of standard clinical risk models.
This large-scale study compared AI algorithms to traditional clinical risk models using a vast dataset of mammograms. The AI algorithms proved to be more effective in predicting the five-year risk of breast cancer, offering potential benefits in tailoring individual patient care and improving prediction efficiency.
The study, conducted at Kaiser Permanente Northern California, analyzed a random sub-cohort of 13,628 women who underwent negative screening mammograms in 2016. Additionally, the researchers examined all 4,584 patients from the same cohort who were diagnosed with cancer within five years. The study encompassed the entire follow-up period until 2021.
The research team divided the five-year study period into three categories: interval cancer risk (cancers diagnosed between 0 and 1 year), future cancer risk (cancers diagnosed between one and five years), and all cancer risk (cancers diagnosed between 0 and 5 years).
Five AI algorithms, including both academic and commercially available models, generated risk scores for breast cancer based on the 2016 mammograms. These risk scores were then compared to each other and to the clinical risk score provided by the Breast Cancer Surveillance Consortium (BCSC).
“All five AI algorithms demonstrated superior performance compared to the BCSC risk model in predicting breast cancer risk over the five-year period,” stated lead researcher Dr. Vignesh A. Arasu, a research scientist and radiologist at Kaiser Permanente Northern California. “This strong predictive ability suggests that AI can identify missed cancers and utilize breast tissue features to predict future cancer development. It reveals the ‘black box’ potential of AI within mammograms.”
The AI algorithms particularly excelled at predicting high-risk patients who might have interval cancer, an aggressive form that often requires additional screenings or follow-up imaging. For instance, when evaluating women in the top 10% risk category, AI predicted up to 28% of cancers, while the BCSC model predicted 21%.
Even AI algorithms trained for short time horizons, as little as three months, accurately predicted future cancer risk up to five years, even in cases where no cancer was clinically detected by screening mammography. Combining the AI and BCSC risk models further enhanced cancer prediction.
According to Dr. Arasu, some institutions are already utilizing AI to assist radiologists in detecting cancer on mammograms. The future risk score generated by AI, which only takes seconds to compute, could be integrated into the radiology report shared with patients and physicians.
“The use of AI for cancer risk prediction enables us to personalize the care of every woman, a systematic approach that is currently lacking,” Dr. Arasu emphasized. “It is a tool that has the potential to deliver personalized and precise medicine on a national scale.”
This study sheds light on the remarkable capabilities of AI algorithms in predicting breast cancer risk, showcasing the potential for improved patient care and precision medicine.
