PURPOSE
Recent studies demonstrate that addition of neoadjuvant (NA) carboplatin (Cb) to anthracycline/taxane chemotherapy improves pathological complete response (pCR) in triple negative breast cancer (TNBC). Effectiveness of anthracycline-free, platinum combinations in TNBC is not well known. Here we report efficacy of NA carboplatin + docetaxel (CbD) in TNBC.
PATIENTS AND METHODS
The study population includes 190 patients with stage I-III TNBC treated uniformly on two independent prospective cohorts. All patients were prescribed NA chemotherapy regimen of Cb (AUC 6) + D (75mg/m2) given every 21 days × 6 cycles. Pathological complete response (pCR: no evidence of invasive tumor in the breast and axilla) and Residual Cancer Burden (RCB) were evaluated.
RESULTS
Among 190 patients, median tumor size was 35mm, 52% Lymph Node positive and 16% had germline BRCA1/2 mutation. The overall pCR and RCB 0+1 rates were 55% and 68%, respectively. pCR in patients with BRCA associated and wild-type TNBC were 59% and 56%, respectively (p=0.83). On multivariable analysis stage III disease was the only factor associated with a lower likelihood of achieving a pCR. 21% and 7% of patients, respectively, experienced at least one grade 3 or 4 adverse event.
CONCLUSION
The CbD regimen was well tolerated and yielded high pCR rates in both BRCA associated and wildtype TNBC. These results are comparable to pCR achieved with addition of Cb to anthracycline-taxane chemotherapy. Our study adds to the existing data on the efficacy of platinum agents in TNBC and supports further exploration of the CbD regimen in randomized studies.
Neoadjuvant carboplatin plus docetaxel yields encouraging efficacy in TNBC. Patients achieving pCR or RCB I with this regimen demonstrate excellent 3-year RFS and OS without adjuvant anthracycline.
This article presents an overview of the benign conditions that affect the breast for the practicing surgeon. The authors discuss the diagnosis and management of a variety of breast pathologic conditions, including those associated with infection and inflammation as well as proliferative and nonproliferative disorders. The authors also offer their experience with the integration of nurse practitioners in the care of patients with benign breast disease.
Patients with pHPT and either elevated or normal PTH levels present with similar symptoms and calcium levels. The majority of patients with normal PTH have SGD, although adenomas are smaller. This may explain why patients with normal PTH values have less sensitive imaging and more frequently require four-gland exploration.
Our results demonstrated that early conservative intervention for breast cancer patients high risk for BCRL who were prospectively monitored by utilizing BIS significantly lowers rates of BCRL. These findings support early prospective screening and intervention for BCRL. Early detection with patient-directed interventions improves patient outcomes and decreases the risk of persistent BCRL.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
