Dear OncoLink "Ask The Experts,"
Has any new information come out at recent conferences about the addition of aromatase inhibitors after 2.5 yrs. of Tamoxifen for estrogen-positive DCIS, after a lumpectomy with clear margins? A consultation indicated that it was not necessary in my case. In my research, I find that 5 yrs. of Tamoxifen is considered adequate for DCIS.

Jul 1, 2010 - Only half of hormone-sensitive stage I to III breast cancer patients prescribed adjuvant hormonal therapy adhere to that therapy for the full duration at the optimal schedule, and younger women in particular are at high risk of non-adherence, according to a study published online June 28 in the Journal of Clinical Oncology.
