Capecitabine monotherapy: review of studies in first-line HER-2-negative metastatic breast cancer.
ABSTRACT The goals of treatment for metastatic breast cancer (MBC) are to prolong overall survival (OS) while maximizing quality of life, palliating symptoms, and delaying tumor progression. For many years, anthracyclines and taxanes have been the mainstay of treatment for MBC, but these agents are now commonly administered earlier in the course of the disease. A recent meta-analysis revealed adverse effects on OS and overall response rates in patients with MBC receiving first-line anthracycline-based chemotherapy following relapse on adjuvant chemotherapy. Noncrossresistant cytotoxic agents and combinations that combine high clinical activity and acceptable tolerability while being convenient for patients are therefore needed for the first-line treatment of MBC patients. Capecitabine has substantial antitumor activity in the first-line treatment of patients with MBC in prospective, randomized, phase II/III clinical trials as monotherapy and in combination with biologic and novel agents. First-line capecitabine monotherapy has a favorable safety profile, lacking myelosuppression and alopecia, and does not compromise the administration of further lines of chemotherapy. Capecitabine is suitable for long-term administration without the cumulative toxicity that can limit the prolonged use of other chemotherapy agents. Here, we review the available data on capecitabine as a single agent for first-line treatment of patients with human epidermal growth factor receptor 2-negative MBC.
Article: The effect on tumor response of adding sequential preoperative docetaxel to preoperative doxorubicin and cyclophosphamide: preliminary results from National Surgical Adjuvant Breast and Bowel Project Protocol B-27.[show abstract] [hide abstract]
ABSTRACT: The National Surgical Adjuvant Breast and Bowel Project Protocol B-27 was designed to determine the effect of adding docetaxel after four cycles of preoperative doxorubicin and cyclophosphamide (AC) on clinical and pathological response rates and on disease-free and overall survival of women with operable breast cancer. Women (N = 2,411) with operable primary breast cancer were randomly assigned to receive either four cycles of preoperative AC followed by surgery (group I), or four cycles of AC followed by four cycles of docetaxel, followed by surgery (group II), or four cycles of AC followed by surgery and then four cycles of docetaxel (group III). Clinical and pathologic tumor responses to preoperative therapy were assessed. Mean tumor size (4.5 cm) and other key characteristics were evenly balanced among the three treatment arms. Grade 4 toxicity was observed in 10.3% of 2,400 patients during AC treatment, and in 23.4% of 1584 patients during docetaxel treatment. Compared to preoperative AC alone, preoperative AC followed by docetaxel increased the clinical complete response rate (40.1% v 63.6%; P <.001), the overall clinical response rate (85.5% v 90.7%; P <.001), the pathologic complete response rate (13.7% v 26.1%; P <.001), and the proportion of patients with negative nodes (50.8% v 58.2%; P <.001). Pathologic primary breast tumor response was a significant predictor of pathologic nodal status (P <.001). The addition of four cycles of preoperative docetaxel after four cycles of preoperative AC significantly increased clinical and pathologic response rates for operable breast cancer.Journal of Clinical Oncology 11/2003; 21(22):4165-74. · 18.37 Impact Factor
Article: The impact of cancer and chemotherapy: perceptual similarities and differences between cancer patients, nurses and physicians.[show abstract] [hide abstract]
ABSTRACT: An essential condition to provide optimal care to cancer patients is a thorough understanding of the worries and needs of these patients. To assess and compare perceptions about the impact of cancer and chemotherapy of health-care providers and patients. Breast cancer survivors (N=80), oncology nurses (N=41) and physicians (N=49) with oncology experience completed a psychophysical scaling method with items tapping both the physical and psychosocial effects of cancer and chemotherapy. The following five issues ranked highest among patients: fear of metastases, fatigue, consciousness of one's own vulnerability, hair loss and nausea. Whereas there was a strong correspondence between the ratings of nurses and physicians, both groups grossly overestimated and underestimated various issues. For example, the effects on relationships with partners and children were greatly overestimated by nurses, while physicians underestimated hair loss the most. There was a considerable discrepancy on various issues between perceptions of patients and medical professionals. The observed lack of correspondence between patients and health-care providers may result in inappropriate provision of attention and health care. Methods have to be developed to assess easily the main needs and worries of individual patients, which is an essential condition to be able to provide optimal care.European Journal of Oncology Nursing 05/2008; 12(2):97-102. · 1.41 Impact Factor
