Purpose: We report a retrospective exploratory analysis of the association of the research-based prediction analysis of microarray 50 (PAM50) subtype predictor with pathologic complete response (pCR) and event-free survival (EFS) in women enrolled in the NeOAdjuvant Herceptin (NOAH) trial.Experimental Design: Gene expression profiling was performed using RNA from formalin-fixed paraffin-embedded core biopsies from 114 pretreated patients with HER2-positive (HER2 þ ) tumors randomized to receive neoadjuvant doxorubicin/paclitaxel (AT) followed by cyclophosphamide/methotrexate/fluorouracil (CMF), or the same regimen in combination with trastuzumab for one year. A control cohort of 42 patients with HER2-negative tumors treated with AT-CMF was also included. The PAM50 subtypes, the PAM50 proliferation score, and the PAM50 risk of relapse score based on subtype (RORS) and subtype and proliferation (RORP) were evaluated.Results: HER2-enriched (HER2-E) tumors predominated within HER2 þ disease, although all PAM50 intrinsic subtypes were identified across the three cohorts. The OR for achieving pCR with trastuzumabbased chemotherapy for HER2 þ /HER2-E and HER2 þ /RORP-high were 5.117 (P ¼ 0.009) and 8.469 (P ¼ 0.025), respectively, compared with chemotherapy only. The pCR rates of HER2 þ /HER2-E and HER2 þ / RORP-high after trastuzumab-based chemotherapy were 52.9% and 75.0%, respectively. A statistically nonsignificant trend was observed for more pronounced survival benefit with trastuzumab in patients with HER2 þ /HER2-E and HER2 þ /RORP-high tumors compared with patients with HER2 þ /non-HER2-E and HER2þ /non-RORP-high tumors, respectively. Conclusions: As determined by EFS and pCR, patients with HER2þ

The purpose of this study was to identify diabetes care and education issues for Latinos with diabetes. Four focus groups of Latinos with diabetes were held in the Detroit area; these sessions were audiotaped. An expert panel of bilingual health professionals from the United States and Mexico reviewed the audiotapes and identified and prioritized 47 issues using a modified Delphi technique. The highest priority issue identified by a wide margin was the difficulty many Latina women with diabetes have with self-care because of other family responsibilities. Universal diabetes care issues have a specific cultural expression which, when identified, can be incorporated into diabetes care and education programs for a particular cultural group. Focus groups are a useful means for identifying and illuminating such issues.
