Abstract
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 ≥ 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.
