Herceptin recurrance success stories (esp. large node+\'s)??

I was dx'd with Stage IIIC b/c in January 04 while pregnant (33 at the time - baby was early but is fine). 2.5 cm tumor, with 11/18 lymph nodes involved (largest was 3.8cm). ER 0%, PR 27%, Her2+ 2.7, grade III, etc, etc.

I'm on A/C *4 (3 weeks), Taxotere *4 (3 weeks), and herceptin for a year. Plus radation.

Looking for success stories of patients who have been on herceptin for a while (over a couple of years) and especially with extensive lymph node involvement. My chance of mets is >50%....I'm just wondering if herceptin will help much in preventing recurrance?

Thanks in advance!!
