Has anyone had Doxil start working after 5-6 rounds?

I just had round 6 of Doxil.  My cancer has been stable, even though I'm feeling better.  This last infusion (round 6), my CA-125 started to fall.  I'm supposed to start with a new doctor in April (my husband is in the military and we are moving to a new state).  My other doctor would like me on a clinical trial.  Here are my CA-125 readings (they are accurate for me):

Before chemo: 90
Round 1: 109
Round 2: 169
Round 3: 172
Round 4: 178
Round 5: 170
Round 6: 132

I'm getting at least two more rounds, and I will be getting a scan in April.

Thanks!
