简要总结
Evaluate if the two carboplatin containing chemotherapy regimens will reduce the growth of breast cancer cells in women with Stage I, II, or III triple negative breast cancer.
详细描述
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 toxicity.
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.
