My sister completed the standard of care 12 rounds Folfirinox and her doc at Memorial Sloane- Kettering is giving her a 2 week "break" before starting capecitabine. She was diagnosed in July 2023 and visited Mayo in August. Staged at Stage IV, not a candidate for surgery, and has arterial involvement. Folfirinox began back at home at MSK. She has had good results with the treatments though it has taken its toll on her.

Prior to her last Folfirinox infusion her CA19-9, and CEA went up slightly which concerned me.
Not sure what to expect from capecitabine, which I understand to be a pro drug of 5 FU --- Nausea/vomiting? Daily pill?

Anyone have experience with this drug?

Thank you.
