Safety and tolerability of docetaxel, cyclophosphamide, and trastuzumab compared to standard trastuzumab-based chemotherapy regimens for early-stage human epidermal growth factor receptor 2-positive breast cancer.

Purpose: We evaluated the tolerability and cardiac safety of docetaxel, cyclophosphamide, and trastuzumab (TCyH) for the treatment of early-stage human epidermal growth factor receptor 2 (HER2)-positive breast cancer and compared to the standard trastuzumab-based chemotherapy regimens doxorubicin with cyclophosphamide followed by paclitaxel and trastuzumab (AC-TH) and docetaxel, carboplatin, and trastuzumab (TCaH).

Methods: We retrospectively reviewed early-stage, resectable, HER2-positive breast cancer patients treated with trastuzumab-based chemotherapy at a single comprehensive cancer center between 2004 and 2011. Patient characteristics, comorbidities, relative dose intensity (RDI) of each regimen, tolerability, and cardiac toxicity were evaluated.

Febrile neutropenia in adjuvant docetaxel and cyclophosphamide (TC) with prophylactic pegfilgrastim in breast cancer patients: a retrospective analysis.

US Oncology Research Trial 9735 reported that TC improved overall survival when compared to doxorubicin and cyclophosphamide in early-stage breast cancer. Despite 61% grades 3-4 neutropenia in the TC arm, only 5% of patients developed febrile neutropenia (FN) without primary prophylactic GCSF (ppGCSF). TC has risen in popularity, particularly in older patients or in those where an anthracycline is contraindicated.

Osteonecrosis of the jaw: dental outcomes in metastatic breast cancer patients treated with bisphosphonates with/without bevacizumab.

The etiology, optimal management, and outcome of osteonecrosis of the jaw (ONJ) are not well understood. Because healing after mucosal trauma requires revascularization, theoretically, the combination of bevacizumab (bev) and a bisphosphonate (BP) could affect the time to development of ONJ and/or the response to dental therapy. We reviewed all cases of ONJ in metastatic breast cancer patients treated at our institution with bev+BPs and BPs alone between October 2002 and April 2010.

Weekly ixabepilone administration in heavily pretreated metastatic breast cancer patients.

Ixabepilone 40 mg/m(2) administered on an every 3-week schedule is approved for use in metastatic breast cancer (MBC) as monotherapy, or in combination with capecitabine in anthracycline/taxane resistant tumors. Because the mechanism of action and toxicity profile is similar to the taxanes, it has been suggested that weekly administration (15-20 mg/m(2) on days 1, 8, 15 for 28 days/cycle) may provide a therapeutic advantage while minimizing toxicity. We report 24 MBC patients treated with weekly ixabepilone.
