This phase of treatment, which involves visits every 10 days or so, lasts about 48 days, then she'll take a break for her counts to recover. The fourth phase involves eight different chemotherapies administered at different intervals, including 21 days of steroids--yikes!. The last maintenance phase will involve monthly clinic visits, and it will end two years following the start of phase 3, so we're looking forward to being done on May 31, 2007!
Here's a breakdown of the medication schedule for phase 3:
|Methotrexate||IV (Intravenous, increasing doses with each visit)||1, 11, 21, 31, and 41|
|Vincristine||IV||1, 11, 21, 31, and 41|
|PEG-aspariginase||IM (Intramuscular--thigh shots)||2 and 22|
|Methotrexate||IT (Intrathecal--via spinal tap/lumbar puncture)||1 and 21|
