I just wanted to provide an update on my dad's condition. We recently crossed the 'one-year since diagnosis' milestone. A recent scan revealed that all of the original sites have either resolved or displayed interval reduction. That said, two new suspicious/inconclusive sites have popped up in the spine - the oncologist has decided to 'wait and see' by continuing with the current Alimta maintenance.
Performance-wise, he's generally well, save for the fatigue which tends to aggravate during the period immediately following each infusion.
So this marks our being on maintenance for 9 months or so now. Here's hoping we can have a lasting effect with Alimta.
