BACKGROUND Anticancer chemotherapy is thought to be effective by means of direct cytotoxicity on tumor cells. Alternative mechanisms of efficacy have been ascribed to several common anticancer agents, including cyclophosphamide (CTX), methotrexate (MTX), anthracyclines and taxanes, postulating an antiangiogenic activity. PATIENTS AND METHODS We evaluated(More)
Antiangiogenic agents and therapeutic strategies have entered the clinical oncology arena. The classical tumor size measurements defined to monitor efficacy of chemotherapy, however, might not be appropriate for these newer therapeutics. We previously found that circulating endothelial cells (CECs) were increased in number and more viable in cancer patients(More)
BACKGROUND Breast cancer rarely occurs in young women. Our knowledge about disease presentation, prognosis and treatment effects are largely dependent upon older series. MATERIALS AND METHODS We evaluated biological features and stage at presentation for 1427 consecutive premenopausal patients aged < or = 50 years with first diagnosis of invasive breast(More)
BACKGROUND We previously demonstrated efficacy and impact on serum vascular endothelial growth factor (VEGF) for metronomic cyclophosphamide (C) and methotrexate (M) in patients with breast cancer. New metronomic schedules were investigated. PATIENTS AND METHODS Patients with advanced breast cancer were randomized to receive oral C (50 mg daily) and M(More)
HER2/neu overexpression is linked to promotion of angiogenesis in breast cancer. We therefore tested the activity of the combination of Trastuzumab with metronomic, low dose chemotherapy with cyclophosphamide (CTX) and methotrexate (MTX) in metastatic breast cancer (MBC). Between April 2002 and June 2005, twenty-two patients with metastatic breast cancer(More)
PURPOSE This is a noncomparative, randomized, phase II trial of preoperative taxane-anthracycline in combination with trastuzumab, lapatinib, or combined trastuzumab plus lapatinib in patients with human epidermal growth factor receptor 2 (HER2) -positive, stage II to IIIA operable breast cancer. The primary aim was to estimate the percentage of pathologic(More)
BACKGROUND Aging remains one of the single greatest risk factors for the development of new breast carcinoma. The aim of the study was to evaluate the relation between biologic features at first diagnosis of breast carcinoma and treatment choice for postmenopausal women > or = 50 years to optimize treatment in the elderly. METHODS The sample included 2999(More)
The use of primary systemic cytotoxics leads to a high remission rate in patients with breast cancer. Response was identified as an important variable associated with survival. Thus, features which predict response, are potentially relevant for planning treatments and improving survival. Retrospectively, we investigated several histopathological features(More)
The clinical efficacy and antiangiogenic effect of low-dose, metronomic administration of cyclophosphamide (CTX) and methotrexate (MTX) (CM) have been demonstrated. The authors report results and long-term follow-up for patients with metastatic breast carcinoma who obtained prolonged clinical benefit with CM. Prospectively collected data from two successive(More)
507 Background: This is a randomized phase II trial of preoperative taxane-anthracycline in combination with trastuzumab, lapatinib, or combined trastuzumab and lapatinib in HER2 positive, stage II-IIIA breast cancer patients. Primary aim of the study is the percentage pathological complete response (pCR), defined as complete disappearance of invasive tumor(More)
