Snowflake, it is my cynical opinion that we will all be dead- from whatever, not necessarily PCa- before there are good clinical randomized control trials on anything other than patented medicines, to prove or disprove anything natural. Though I also cynically believe that if something negative pops up, we are more likely to hear about
that- and quicker, than the opposite. For example, from the same website that RobertC linked to about
an Israeli study on MCP, I recently expressed frustration that no results have been posted on a clinical trial on Vitamin D given to men 2 months prior to RP surgery. This study was completed in either March or Dec of 2015:
/clinicaltrials.gov/ct2/show/NCT02726113?term=vitamin+D+prostate+cancer&rank=3Somebody said...
Enrollment: 49
Study Start Date: October 2011
Study Completion Date: December 2015
Primary Completion Date: March 2015 (Final data collection date for primary outcome measure)
And yet still no results available. What could possibly be taking so long to tell us either that the vitamin D killed all of the participants, or that it had no effect, or that it was actually harmful in regards to their PCa? Why is this stuff so glacial in progress?
What was really interesting was watching a video of a presentation at a conference of MDs and researchers of a previous study by these same people, discussing a similar study done on men on active surveillance and this upcoming study of men on RP. He discussed how hard it was to get the FDA to allow them to do tis clinical trial, how they had to convince the FDA they were not going to kill these men by giving them 4000 IU/day of Vitamin D, and how they had to do it just like a drug trial, even had to call it a drug trial. I previously posted a video of this conference and this researcher discussing this somewhere here long ago.
Anyway, bottom line is, IMO which is just an opinion and subject to error, unless a company can hope to make millions or billions off of some research, in my opinion you can not expect to see much about
it as far as the gold standard clinical RCT studies go. And when you do find some research, you also have to figure out if there were any biases involved in the study, any reason those doing the "research" would have for not wanting to report good results for whatever it is, or vice versa. That is no easy task.
So you will just have to look at the meager info available, especially looking at the evidence of any harm ( whether diet or supplement) and make your best guess about
whether it seems to be a reasonable risk/reward ratio to add something to the treatment. Include the docs in this to make sure it won't interfere with the treatment. At least it will never cost you much compared to all of the other treatments and meds you will dealing with anyway, and who knows very often one thing(diet or supplement) hopefully helpful for PCa will also be helpful for various other diseases and heart health. Or, for example, if you like broccoli and radish or slaw(the later 2 have the enzyme in broc often destroyed by heat), it cost you nothing as you just make sure that is part of the food you pay for anyway. And if it helps 10% or more, that is major bang for the buck. If not, you have not lost very much, unless you ate food you do not like.
Good luck on your research!
