Small cell

i am looking for help and or opinions as to what or where I might look for help fighting my small cell prostate cancer after they quit giving me chemo.  I am working with Mayo of Rochester and LaCross.  At present they are thinking of doing at least three rounds of chemo, which I have had only one round (3 days) so far.  After the second round they plan a other ct scan to see if the chemo has helped.  They tell me after I finish chemo at some point the cancer will mutate and come back very fast and they have nothing to use against it!   Help!
