Hi.. I just came across your message. I am a 27 year osteosarcoma survivor (I was diagnosed with Osteo in my left humerus in 1982)
Back then, they were just starting to look into joint replacement.. however my tumor was so large that with the technology of the time they were unable to do it.. so I had a four quarter amputation of my left arm and shoulder. I had no pre-op chemo.. they just rushed me into surgery (2 weeks after diagnosis) and then I started on high dose methotrexate, cisplatin, and adriamyacin (related to dox). They had to stop the chemo early because my kidneys went kerplunk.. but fortunately once stopped, I got 50% function back.. so I am pretty much symptom free, just getting checked every 6 months by a nephrologist. I believe they tweaked dosages because mine was experimental.. so now a lot of the risks are reduced.
I really mean this to be a positive message however.. that I recovered VERY quickly from my surgery (I was actually up and about within a week.. out of the hospital) and the chemo was tough, but I think it saved my life. I'm sure there are advances in the anti-nausea stuff now, my advice is to stay on top of that kidney function.
I thank God every day that my parents were tough on me.. forcing me to adapt and learn to do for myself rather than spoil me. As a result, I have a pretty "normal" life.. I am back in college after working awhile post BS degree to get my grad degree in biology, and I really am hoping to go into cancer research eventually.
Just wanted to say that the best medicine is a positive outlook and plenty of prayer. I can't really answer your question since I didn't have pre-op chemo, but it sounds promising. Mine was a "grab and go and try to fix it later" approach. :)
