Hi Vicki -
My husband is one that had a stroke following avastin treatments (the avastin is believed to be the cause), his tumor is an anaplastic oligo-astrocytoma. My husband's stroke happened about 6 weeks after his last avastin treatment, he was on it for 6 months. Neurologically, he continued to decline the entire time he was on the avastin. His tumor is on his speech center, and when he would have "episodes" he would have severe aphasia. He also started with numbness and pain in his right arm. His NO at the time said it was because of the tumor and had nothing to do with the avastin. As for teeth, he didn't have problems with loose teeth, but has managed to chip two of his teeth on a fork, while eating, within a year of being off the avastin.
His other avastin side effects - his BP skyrocketed with in about 3 months of being on avastin - something like 195/115 is about where it go to 115/70 was his normal - it took 3 meds to control it. He had nose bleeds. He also had these dark lines that showed up on his fingernails - kind of like the white marks that some people get, but these were almost black in color.
Please keep an eye on anything else that starts happening with your husband, anything that doesn't seem "right". Be sure that they are doing blood work and urine samples on him!! Other oligo patients I have talked to have had strokes on avastin, and most of their strokes had similar precursors that I have mentioned as side effects. I don't know if they can be prevented, but I personally hold a lot of anger that the stroke possibility wasn't stressed more before my husband was put on Avastin. Oligo's tend to have a lot more blood vessels than other tumors. They actually have a history of bleeding on their own.
Has your husband been on anything other than temodar, chemo wise? There are a lot of other chemo options out there that oligo's might respond to.
Anything I can do, answer, etc....just let me know.
