Big data analytics joins the fight against prostate cancer

DataIQ News

Further evidence has emerged of big data analytics' role as a force for good with the publication of new research by The Institute of Cancer Research which it is hoped will enable health professionals to personalise radiotherapy treatment for prostate cancer by predicting men’s risk of side effects.

As the annual Movember event starts to gather pace, researchers have, for the first time, applied big data analytics to information from more than 700 men given radiotherapy to treat their prostate cancer. This included medical history, genetics, radiotherapy dose, and reported side effects.

Advances in technology allow huge amounts of different information to be combined and analysed at once. This technique is already used in many different settings, including to improve the accuracy of weather forecasts, make investments and trading decisions, and even monitor premature babies.

Researchers in this study used state-of-the-art artificial intelligence to highlight which information might predict sensitivity to the side effects of prostate radiotherapy. In particular, specific genetic characteristics – SNPs (single nucleotide polymorphisms) – were predictive of a patient suffering bleeding.

At the moment there is no way to adjust doses of radiotherapy according to how sensitive a patient might be to the side effects. This means that while some men are receiving too much and suffering side effects, some are given too little and this compromises the chances of successful treatment.

Side effects include bowel, urinary and sexual dysfunction and can be difficult for patients to tolerate and can persist after treatment.

The researchers suggest that with further validation, this information could be used to create personalised treatment plans for prostate cancer patients. The technique could also be applied to many other types of cancer that are treated with radiotherapy.

Dr Navita Somaiah, co-lead researcher at The Institute of Cancer Research, London, said: “Advances in technology have enabled us to combine what we’ve learnt from decades of research into radiotherapy. For the first time, we can now look at the full complexity of a patient’s genetics, medical history and treatment, to predict if they are at risk of side effects.

“We hope that our method can be used to personalise radiotherapy for patients based on this risk, improving the chances of a cure and also minimising the side effects suffered. This has been a huge collaborative effort between clinicians, physicists, biologists, statisticians and data scientists.”
