Plus, as I found out, I feel the oral version is more effective with less side-effects anyway.
One thing I learned from this forum though is the difference between Xeloda and 5FU. I've read some posts saying some Onc would recommend infusion over Xeloda is because they can be sure how much actually went into your body. I couldn't quite get what that meant then, but after I literally threw up 1/2 of the pills everyday, I really couldn't be sure how much went into my body.
Since I have the port anyway, I went back to Folfox straight away. I'm not recommending either, I'm just sharing my experience and what I understood.
