Artificial intelligence predicts treatment effectiveness

19/11/2018

How can a doctor predict the treatment outcome of an individual patient? Traditionally, the effectiveness of medical treatments is studied by randomised trials where patients are randomly divided into two groups: one of the groups is given treatment, and the other a placebo. Is this really the only reliable way to evaluate treatment effectiveness, or could something be done differently?

Cancer identity technology makes it easier to find tumor's "address"

16/11/2018

Purdue University researchers have developed a technology aimed at making it easier to deliver cancer treatment to the right "address" in the body while also easing the painful side effects of chemotherapy on patients. One of the big issues with chemotherapy is that most treatment approaches focus on the tumor itself without paying attention to the microenvironment surrounding the tumor.

Prostate cancer radiotherapy can be more precisely targeted

09/11/2018

Current standard imaging techniques for initial staging of prostate cancer often underestimate the extent of disease beyond the prostate. A study featured in The Journal of Nuclear Medicine's November issue demonstrates that prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) can pinpoint prostate cancer locations with superior accuracy.

Health data under lock and key

08/11/2018

Researchers from the Collaborative Research Center CROSSING at Technische Universität Darmstadt have developed a solution that will ensure decades of safe storage for sensitive health data in a joint project with Japanese and Canadian partners. An initial prototype was presented during a recent conference in Beijing, China. The system will go into trial operation in Japan in the coming weeks.
