I know she is being treated with novantrone for her MS. He said that in the first line.
Actually, the only information I have for this case is:
Report 8: Correspondence
'Her oncology consultant sends a letter to -name omitted-'s primary care physician, the requesting doctor. The results of her exam and her treatment plan are described. A copy of the letter was forwarded to the psychiatrist to whom the patient has been referred. See figure QC8-1, Structures of a Neuron.'
Glossary:
Marche a petits pas [Fr.] - abnormal gait, taking very short steps.
Then a pretty pictures of a neuron.
Other than google, that's about all the resources I have for this case.

I'm starting to think it might be 'She has had a waxed and waned course, but till recently she has never been in remission.'...waxed and waned meaning that her symptoms have been coming and going, but never into remission.
Gah, I think I figured it out on my own! Just needed to rant about it without listening to his football game.
