Honestly, I think the answer for me will be from the responses of all the respected people I've learned so much from on this site.
I'm 59, DX April 2017, widespread bone mets up spine, skull, ribs, upper body. A couple of the biopsy doctors wondering how I could walk much less touch my toes. No spread to lymph nodes or any other soft tissue. Lupron and chemo in May 2017 and through out chemo cycle treatments with Lupron, my MO was never happy with my PSA levels. His remark that it bounces around too much. In fear Lupron wasn't doing enough and knowing more cancer drugs would be coming, I had surgical castration in September. Mid October all new scans were done to compare to baseline scans and the chemo did a nice job eradicating most all of the out lying mets but only about 60% of the mets covering the spine and upper back. PSA was 1.0, all and all, it was considered a success. Insurance won't allow Zytiga yet.
I went back to see my MO the 2018 new year and the PSA had jumped from 1.0 to 6.71 so we did another round of scans. NO new growth, two places on my middle spine grew from the size of a dime to a penny, (me expecting to look like I did a year ago, so I was relieved, the MO is all concerned). I start Zytiga and get an appt at MD Anderson who confirm my past present and future treatments. Two months of Zytiga and PSA goes from 6.71 to 1.26, some good news for once. MO pleased for once. A month passes by and a scheduled blood-work appt with PSA and it goes from 1.26 to 1.99, yep, that's me. I inquire if I should refill the Zytiga since I'll run out before I see him again and he calls and he says yes fill it, this is "worrisome".
The next day I get a letter from the insurance company approving me for another dose of Docetaxel. Knowing my MO, he isn't checking for the late summer or fall, he is going to bring this up on May 30th on our appointment.
I've had two MO's tell me this is going to kill me. I feel better today than I probably have since the first day of chemo. There are a lot of physical things I could do I can not do now because of chemo. If I take this chemo again, will I be able to bounce back to this level again? Right now, I have plans and don't want to interrupt me and my wife retirement moving plans because I'm not able to because of chemo, I'd rather wait until we've moved and then take it. Will delaying the treatment 6 months really make a difference. Will taking chemo really help anyway? I don't want to swap months for months. All advice will be appreciated!
Thanks again to all for their support and wisdom!
