Unlabelled: The feasibility and efficacy of adriamycin or epirubicin in combination with cyclophosphamide followed by weekly paclitaxel (AC/EC-weekly PAC) as adjuvant chemotherapy for breast cancer was investigated.

Patients And Methods: Node-positive breast cancer was treated with AC/ EC-weekly PAC, namely AC at 60/600 mg/m(2) or EC at 90/600 mg/m(2) x4 at three-week intervals, followed by weekly PAC (80 mg/m(2)) x 12, namely four cycles of single weekly administration for three weeks followed by a one-week rest (3 x 4 PAC) or single weekly administration for 12 consecutive weeks (12 PAC).

Results: One hundred and three of 109 consecutive patients enrolled were analyzed, of whom 96 (93.

Purpose: To evaluate the efficacy and tolerability of dofequidar plus cyclophosphamide, doxorubicin, and fluorouracil (CAF) therapy in comparison with CAF alone, in patients with advanced or recurrent breast cancer. Dofequidar is a novel, orally active quinoline derivative that reverses multidrug resistance.

Patients And Methods: In this randomized, double-blind, placebo-controlled trial, patients were treated with six cycles of CAF therapy: 28 days/cycle, with doxorubicin (25 mg/m2) and fluorouracil (500 mg/m2) administered on days 1 and 8 and cyclophosphamide (100 mg orally [PO]) administered on day 1 through 14.

The efficacy and safety of combination therapy of 4 cycles with docetaxel 70 mg/m(2)every 3 weeks and trastuzumab as primary chemotherapy for operable breast cancer was determined in 21 patients (pts) by assessing the pathological complete response (pCR) rate, clinical response rate (RR), breast conservation surgery (BCS) rate and toxicities. To date, 19 pts have completed surgery. The pCR rate was 21% [95% CI 6%-46%] .

Background: Pre-clinical and clinical studies indicate that a combination of docetaxel and trastuzumab may effectively treat patients with human epidermal growth factor receptor-2 (HER-2) overexpressing metastatic breast cancer. We evaluated the efficacy and safety of this combination in a multicenter, open-label phase II study in Japan.

Methods: Women with metastatic breast cancer whose tumors overexpressed HER-2, as assessed by immunohistochemistry and by fluorescence in situ hybridisation, received 2 to 6 cycles of docetaxel (70 mg/m2, every 3 weeks) and trastuzumab (4 mg/kg loading dose, 2 mg/kg weekly thereafter).

Unlabelled: Some small tumors of the breast cannot be diagnosed by needle biopsy, and an excisional biopsy is occasionally needed for the diagnosis. Sentinel node navigation surgery is frequently suitable for patients with such small breast cancers. The purpose of this study was to compare sentinel lymphoscintigrams in breast cancer patients who had previously undergone excisional biopsy with sentinel lymphoscintigrams in patients undergoing no excisional biopsy.

Background: At present, it is one of the most important issues for the treatment of breast cancer to develop the standard therapy for patients previously treated with anthracyclines and taxanes. With the objective of determining the usefulness of vinorelbine monotherapy in patients with advanced or recurrent breast cancer after standard therapy, we evaluated the efficacy and safety of vinorelbine in patients previously treated with anthracyclines and taxanes.

Methods: Vinorelbine was administered at a dose level of 25 mg/m(2) intravenously on days 1 and 8 of a 3 week cycle.

Docetaxel and trastuzumab can be considered to be active drugs for HER 2-overexpressing metastatic breast cancer (MBC). This study was conducted to determine the activity of combination therapy with docetaxel and trastuzumab in MBC patients (pts) by assessing the response rate (RR), time to progression (TTP) and safety. We administered the combination of docetaxel 70 mg/m2 every 3 weeks and trastuzumab using a 4 mg/kg loading dose and thereafter 2 mg/kg weekly.

Purpose: To investigate the efficacy and safety of zoledronic acid for the treatment of bone metastases from breast cancer.

Patients And Methods: Women with bone metastases (N = 228) were randomly assigned to receive 4 mg zoledronic acid (n = 114) or placebo (n = 114) via 15-minute infusions every 4 weeks for 1 year. The primary efficacy end point was the skeletal-related event (SRE) rate ratio between treatment groups.

Purpose: Docetaxel is an active agent as first-line chemotherapy in patients with advanced breast cancer at a dosage of 100 mg/m2. However, the efficacy of this agent as a first-line drug when used at a lower dosage is unclear. This study was performed to evaluate the clinical efficacy and safety of 60 mg/m2 docetaxel for the treatment of breast cancer.

We studied the usefulness of the oral 5-FU anti-cancer drug 1-hexylcarbamoyl-5-fluorouracil (HCFU) + cyclophosphamide (CPM) + tamoxifen (TAM) (HCT group) in comparison with CMF + TAM (CMFT group) in adjuvant therapy for breast cancer by a non-inferiority study based on a multi-institutional joint study. Clinical stage I, II primary breast cancers with histologically positive axillary lymph node metastasis were randomly assigned to the HCT group or the CMFT group after primary surgery. We registered 136 cases (HCT group 68 cases, CMFT group 68 cases).

Unlabelled: Fundamental studies have confirmed that combination chemotherapy with docetaxel and doxifluridine (a capecitabine metabolite) is very useful in the treatment of breast cancer. This study investigated the usefulness and tolerability of a combination chemotherapy consisting of docetaxel administration on day 8 of doxifluridine therapy in 40 advanced/recurrent breast cancer patients. The overall response rate was 41.
