Ask HN: How to Find the Best Info on Cancer Treatments?

Hi Everyone, one of my close relatives has been diagnosed with Stage IV Glioblastoma (GBM), and while there's literally tons of information online about treatments and procedures, how would one go about digesting it all ? For example there's 75 publications from the recent ASCO 2015 congress about GBM treatments, is there any tool out there to compare what works vs what does not work as well? Another question would be, how to find the best specialists in my Area for this kind of cancer?

Any help/advice is very much appreciated!
