In the context of prostate cancer, newly diagnosed men with low and intermediate disease often consider focal therapy modes such as cryotherapy, HIFU or targeted radiation for intial treatment. And more frequently, we are seeing some of these modes employed for adjuvant and salvage therapy.
AnCan’s good friend, John Fortin, just published a short report on UroToday summarizing the findings from a Febraury 2020 Conference that considered focal therapy. This may well be of interest to other cancers, like ovarian and breast, where focal modes are also employed. John’s report linked above does not address follow-up treatment in the case of recurrent disease after intial treatment.
