Trisha, personally I would try and save the one good cane with the leaves, and maybe use the sphag and bag technique to try save the others.
But I wouldn't lose sleep if I didn't save them.
You can find the sphag and bag technique at

I would probably do as Brook said to save that one good cane, and as long as I could save that one, I would be happy. One good cane is better than several sick ones.
The sphag and bag technique is a good one to learn for saving plants which have not quite reached that point of no return. Then in future if needed, you'll know what to do.
