Belgian researchers have unveiled an artificial intelligence (AI) tool that they have developed with the aim of predicting the results of chemotherapy on cancerous breast tumours. The algorithm identifies cases in which treatment has had an impact, though specialists are continuing to develop the technology.
AI could soon enable doctors to monitor the effectiveness of treatment given to breast cancer sufferers. Researchers at the University of Mons (Belgium) have been using it to predict the results of chemotherapy on cancerous breast tumours, as reported by Numerama.
Specialists presented the tool they have created at the GPU Technology Conference, held on 26-28 March in the USA and organised by Nvidia, the graphics card giant.
The researchers used the Nvidia GeForce GTX 980 processor to carry out their work and began by creating a database using the MRI scans of 40 patients with breast cancer.
Provided by the Jules Bordet Radiology Centre in Brussels, the images were analysed and processed using an intelligent programme developed by the specialists, all with the aim of determining the effect chemotherapy would have on the sufferers’ tumours.
Researchers trained an AI tool to recognise the cases in which chemotherapy would trigger a "response", i.e. have an impact on the tumour.
In extending their work, the scientists plan to use the multi-GPU and increase the number of graphic processors used in their study, creating a method that would enable data to be processed more effectively. Ultimately, their aim is to harness AI to assess the effect of chemotherapy on a breast tumour.
Improvements to be made
Belgian universities are now looking to improve the model to prevent the risk of overfitting. Given the lack of data, conclusions could be deemed unreliable, as the Numerama article explained: "Owing to the small size of the initial database, the results provided by machine learning may not be reliable enough to offer additional data."
Aside from preventing breast cancer, the latest technological innovations could also help improve treatment of the disease.
