Fibromyxosarcoma - Anyone Have Experience With This One?

Yep, here I am again, asking for cancer advice. Long story short - Delta broke her leg 2 weeks ago, just above the wrist joint on her right foreleg. My general vet couldn't repair because the location made it complicated. But, we also saw "pitting" in the ball of the joint on the xray. So, off to an orthopedic vet for help. They took one look at the xrays and said "amputation", not repair. Their radiologist did more xrays and concurred that we were looking at cancer as the cause for the break.

 

The biopsy of the removed leg bone came back today and the verdict is "fibromyxo sarcoma, presence of spindle-cells, soft-tissue sarcoma". I tried a search on Bing of fibromyxo sarcoma in dogs and come up basically empty. Can find info on it in humans but not dogs.

 

I'm just wondering whether anyone else here has dealt with this type of cancer and might offer some advice on what to expect. I've dealt with osteo in 2 dogs, and what I suspect, but wasn't found in time to treat, was lymphosarcoma in another. Fibromyxo is a new one on me.

 

Any info anyone has is greatly appreciated. Thanks!

Sorry you and Delta are going through this...

Fibrosarcoma's can have boney involvement and cause a lytic lesion but, that fact the tumor was found an the carpal area makes me question if the biopsy was misread. To be honest I would have the biopsy read by another pathologist. You could consult with Dr Couto.

Oh my gosh Kate. I am so sorry you and your girl are going through this. Definitely please send the films to Dr Couto, he was wonderfully helpful with Seamus and quick to reply. :grouphug

Kate, I am so sorry to read that you and Delta are going through this. I don't have experience with this diagnosis but I agree that a second opinion would be good. Please know all my thoughts are with you and your beautiful girl. :grouphug

Fibromyxosarcoma is a new one but pathology terms change from time to time. We have experience with fibrosarcoma in our house and know a dog who had an amputation from fibrosarcoma as well. Our boy lived 3.5 years after resection before succumbing to something else. The dog with the amputated leg lived 4 years before he developed osteo in one of his remaining limbs. Dr. Couto is an indispensible resource in helping sort out difficult pathology issues and we have always valued the advice he has given us. Best of luck to you and your pup on this journey.

How is Delta doing? I don't know if you've already tried this, but I used the term fibromyxoid sarcoma when searching for information. I still couldn't find anything related to dogs though. From what I read it is a rare low grade, but aggressive cancer that starts deep in the tissue and often metastasizes to the bones and lungs. Unfortunately there is also pain related with it. :(

Hi, all, thanks for your answers and kind thoughts. I've been traveling and haven't come into the forum since Friday. I a call in to my own vet to talk things over with him, and will consider reaching out to Dr Couto when I get paid this week. Surgery and travel expenses have me maxed out right now.

 

(Travel wasn't exactly my choice: I was due to leave for Philly the week Del broke her leg because my Mom was coming home from the hospital after having major back surgery. I postponed as long as I could, waiting until Del was well on the road to recovery. She is being watched over by a friend who is living at my house while I'm away.)
