e11510 Background: To determine the response, tolerability, and long-term outcome of a neoadjuvant platinum-containing regimen for locally advanced breast cancer (LABC). To search for correlation between pathologic complete response (pCR) and predefined biomarkers in this cohort. Patients and Methods: Patients with LABC received eight cycles of either sequence A or B. Sequence A was doxorubicin 60 mg/m2 and paclitaxel 175 mg/m2 (AT) q3w X 4 followed by cisplatin (C) 60 mg/m2 and paclitaxel 90 mg/m2 (CT) q2w X 4. Sequence B was CT x 4 followed by AT x 4. In addition to estrogen receptor and HER2, immunohistochemistry (IHC) for MDR-1, MRP-1, topoisomerase IIα(topoIIα) and p53 was performed. Results: 88 patients were evaluable for response and toxicity. Median follow-up was 97 months. The overall pCR rate was 21.5%. For subgroups ER+/HER2-, HER2 +, and double negative (ER-/ HER2-) disease the pCR was 5.9%,23.3% and 35% respectively, p=0.006. Five year(y) overall survival for the entire cohort was 71.1%. Five y overall survival was 88.1% (CI 77.1%, 99.1%) for the ER positive HER2 negative group compared to 68.5% (CI 51.3%, 85.7%) and 49.5 (CI 27.4%, 71.6%) in the HER2 positive and “double negative” group respectively (p=0.0077). Over-expression of topo IIα was correlated with pCR (p<0.001). There were no toxic deaths. Conclusions: A platinum-containing neoadjuvant regimen was well tolerated and achieved a pCR rate which compares favorably to other recent studies of multi-agent chemotherapy. Further studies tailored for specific breast cancer subtypes are required. No significant financial relationships to disclose.

Olaparib, an oral PARP-inhibitor, has shown clinical benefit for HER2-negative advanced breast cancer patients carrying a germinal BRCA1/2 mutation. In a randomized Phase III trial, olaparib significantly prolonged progression-free survival as compared with chemotherapy of physician choice. Moreover, in the same trial, a prespecified subgroup analysis reported an overall survival benefit for patients not previously pretreated with chemotherapy for metastatic disease. This review focuses on available preclinical, pharmacokinetic and pharmacodynamic data regarding olaparib and clinical evidence of its antitumor efficacy (both as monotherapy and in combination) and tolerability in breast cancer patients. Open questions, such as use of appropriate biomarkers for patient selection and combination/sequencing with other anticancer drugs, are also addressed.
