Weekly docetaxel/carboplatin as primary systemic therapy for HER2-negative locally advanced breast cancer.

To evaluate the effectiveness and safety of weekly docetaxel/carboplatin as primary systemic therapy (PST) for locally advanced breast cancer, we conducted a phase II study. Forty-four patients with HER2-negative locally advanced or inflammatory breast cancer (IBC) received docetaxel 35 mg/m(2) and carboplatin to an area under the curve of 2 mg/mL/min for 3 of 4 weeks over 16 weeks. After completion of PST, patients had breast surgery and then received 4 cycles of adjuvant cyclophosphamide/doxorubicin, standard radiation therapy, and, for hormone receptorpositive tumors, tamoxifen. The mean tumor size was 9.3 cm (range, 5-24 cm). Thirty-seven patients (85%) had palpable lymph nodes; 13 patients (30%) had matted or fixed nodes (N2). Eight patients had IBC. There were 11 clinical complete responses (25%) and 29 clinical partial responses (66%), resulting in 40 objective responses (91% [95% CI, 78%-96%]). Invasive disease disappeared (pathologic complete response) from the breast and axilla in 6 patients (14% [95% CI, 5%-27%]) and from the axilla in 17 patients (39% [95% CI, 24%-55%]). The only significant adverse hematologic event was grade 3 neutropenia in 4 patients (9%). The most common adverse nonhematologic events were fatigue (84% of patients) and alopecia (84%), which were usually grade 1/2. Weekly docetaxel/carboplatin appears to be active and feasible as PST in patients with large breast tumors.

Docetaxel and cisplatin as primary chemotherapy for treatment of locally advanced breast cancers.

A phase II trial was designed to evaluate the effectiveness of docetaxel/cisplatin as primary or neoadjuvant chemotherapy of locally advanced breast carcinoma (LABC). Patients with newly diagnosed breast cancers > or = 5 cm in size by palpation were treated with docetaxel/cisplatin, both at 70 mg/m2 intravenously every 21 days for 4 courses. Upon completion of chemotherapy, all patients underwent modified radical mastectomy with axillary nodal dissection. Pathologic complete response (pCR) was defined as absence of any invasive carcinoma in the breast. Standard AC (doxorubicin/cyclophosphamide) at 60 mg/m2 and 600 mg/m2, respectively, for 4 cycles was given as adjuvant therapy to maximally eradicate occult distant disease. Between March 1998 and October 2001, 57 women were entered onto this trial, 28 (49%) with inoperable T4 and inflammatory cancers. Pretreatment median tumor size was 9 cm. Thirty-six patients (63%) had estrogen receptor-positive tumors and 10 patients (18%) had tumors with HER2 overexpression. All tumors became operable after neoadjuvant chemotherapy. Pathologic complete response in the breast was achieved in 15 patients (26%) and pCR in the breast and the axilla was achieved in 11 patients (20%). All neoadjuvant chemotherapy courses were administered at full doses without treatment delays caused by toxicity. The most common side effects were hyperglycemia, anemia, and mild neuropathy. The results of this study suggest that the docetaxel/cisplatin combination can be an effective and well-tolerated induction treatment of LABC, even in very large mostly HER2-nonoverexpressing tumors.

Axillary polymastia.

"Polymastia" is a term used to describe the presence of more than 2 breasts in human beings. It is synonymous with supernumerary or accessory breast tissue. Accessory breast tissue has the potential to undergo the same benign and malignant changes as normal pectoral breast tissue.
