Hi Lester
Your Dad has had the gold star treatment so his medical team would seem to be really on the ball. Early chemo is proving to be really beneficial for most men diagnosed with metastatic PCa. Although many others like my friend Allisons's OH have done really well without the chemo as well.
So much depends on the type of PCa ( I think figures show there are more than 20) how the cancer behaves, how aggressive it is and how quickly it adapts and becomes resilient to treatments.
I am Mo that Allison mentioned, my OH Mick was one of the unlucky ones, where nothing worked for more than a very short while. Thankfully cases like his are rare and as more is learnt from trials and all the incredible research that is going on, will become even rarer.
The fact that your Dad has had such a dramatic drop in PSA in a relatively short time and it sounds like he is doing really well on the back of Chemo, is a promising sign.
As Allison says with metastatic disease there is currently no cure, but there are lots of treatments that are having good results already, progress is being made with every new drug or treatment that comes to market. Although there is probably a long way to go for an effective screening test/programme, improving awareness and changing attitudes mean more and more Men are being tested and diagnosed at a cureable stage, work is ongoing to continue to raise awareness, to educate GPs and to provide them with better diagnostic information as well, so the future really is starting to look much better.
I wish you all the best

Mo
