Hi Laurie,
the "disadvantage" is that you need to go 7 vs 3 times. It is also more likely that you end up with a port if you get that many infusions.
I would pay attention to the MD who is more in tune with current treatments. I.e. be careful of the very young and older MDs. (unless the older MD's are current).
so now I have totally confused you!

If it were me I would go for 7 x again. As you can see I started out with cisplatin and had issues (light ringing) even after the very first infusion. So after the second treatment (worse ringing) we had to switch.
