recurrence treatment options

my wife was diagnosed with cancer in dec 2002. she had fluid in her lungs. she began treatments in jan 2003. she received taxol/carboplatin - 6 cycles every third week. her cat scan was clean after the third cycle and continues to be till this day. she completed the 6 cycles in MAY 2003. that was followed by a complete hysterectomy which revealed that the unknown primary was actually ovarian. the biopsies showed residual disease. then my wife had consolidation treatments of taxol for 10 consecutive weeks and was finished in sept 2003, her ca125 has been between 10-16 ever since (currently 13). Second line therpy for recurrences depend on the inteval from the completion of platinum based first line therapy. in my wife's case would that period begin in may 2003, when initial platinum based cycles were completed or november 2004 after the consolidation non- platinum based taxol treatments were completed? finally i have read promising new treatments for recurrent OC, in immunotherapy such as oregovomab or removab. i also read about a new promising 2nd line therapy called bevacizumag. are any of these new treatments looked at as viable second line treatments?

Dear ehr, a correction to my post - the time interval from treatment is usually 6 months from treatment, not 12 months.

if the above is true, why use taxol a non platinum therapy in consolidation treatments and not carboplain.
