It is a bummer, but I should share an update on Xtandi.
I got a bunch of the side effects over the 15 months total I was on it. Nasoesophopharangial inflammation (like a big nasty sore throat) another shingles outbreak, on my legs this time (despite having had both Zostavax and Shingrex vaccinations) that left scars, a series of gum infections, vivid nightmares and sleep disturbance, frequent bloody noses (usually while making breakfast at 4:30 AM) a persistent cough with phlegm, and pruritis on both forearms (patches of nasty itchy bleeding weeping sores that leave scars when they fade). A week or 2 after I finished my last round of radiation treatments in early March this year my calves began to hurt. It got worse and involved my ankles as well. I began to wrap my ankles before I went out for my daily 6.5 miles. On May 29 my wife, Labrador and I went out for our usual hike through the local bush in the river bottom valley. 2.5 miles out I was overcome with pain in my ankles, calves, knees, thighs, hips and lower back. We had to cut the hike short, I barely made it home. When I got home I found myself unable to walk without leaning on counters or tables or the walls. I could not climb the stairs.
The Xtandi website says if you find yourself unable to walk you should stop taking Xtandi immediately and notify your doctor so I quit taking it and told the doc. I was afraid that I had gotten the "collapse of lumbar vertebra and subsequent pinching of the spinal cord" side effect.
Over the last 2 months I have been able to recover enough to get in several 3 mile days and a couple of 4 mile days, but most days I cannot go more than a mile. Normally I do 45 miles a week so I cut back on my food intake. Despite that I have gained a couple of more pounds. I have an appointment with a podiatrist next week and a consult with my MO. Appointments with RO in Oct and the MO head of the cancer dept in Dec. I will not get the next shot of Eligard in Dec and will likely not go back on Xtandi at all. PSA 1 month after quitting Xtandi was less than .1 (test limit) My ORIOLE-style radiation treatments that ended this past March will hopefully have killed back my mets so I can go drug free starting in Dec.
