    Detailed Description

    Sporadic and germline BRCA mutation associated triple-negative breast cancer share several
    pathological and molecular similarities which have led to the exploration of DNA damaging
    agents like platinum compounds in patients with triple-negative breast cancer. Recent
    studies demonstrate that addition of neoadjuvant carboplatin to
    doxorubicin/cyclophosphamide/taxane-based chemotherapy improves pathological complete
    response in patients with stage I-III triple-negative breast cancer but also increase

    A recent study reported encouraging pathological complete response rates with a
    non-anthracycline carboplatin plus docetaxel neoadjuvant chemotherapy regimen in a cohort of
    49 triple negative breast cancer patients. This chemotherapy regimen of carboplatin plus
    docetaxel yielded an overall pathological complete response rate of 65% in unselected
    triple-negative breast cancer with pathological complete response rates of 61% in sporadic
    and 77% in germline BRCA-associated triple-negative breast cancer. The chemotherapy regimen
    of carboplatin/docetaxel is well tolerated and should be studied further and compared with
    regimens that add carboplatin to the standard anthracycline/taxane containing regimens.

    This is the basis for the proposed randomized neoadjuvant phase II study to further estimate
    and compare pathological complete response rates of carboplatin plus docetaxel x 6 cycles to
    carboplatin plus paclitaxel x 4 cycles followed by doxorubicin plus cyclophosphamide x 4
    cycles in stage I-III triple negative-breast cancer.
