Chemoprevention of breast cancer.

Chemoprevention of cancer is a new branch of the medical science and represents a topic of increasing concern in public health. Over the last decade chemoprevention has been extensively studied from many points of view, and topics in the field of chemoprevention have expanded considerably. Breast cancer, the most common malignant neoplasm in women, is one of the areas of clinical interest for chemoprevention. In this paper the authors synthesized the "status of art" in chemoprevention of breast cancer with retinoids and antiestrogens.

Tumor angiogenesis predicts clinical outcome of node-positive breast cancer patients treated with adjuvant hormone therapy or chemotherapy.

PURPOSE: Experimental studies suggest that angiogenesis is necessary for breast cancer progression and metastasis and that it may play a role in responsiveness to some chemotherapeutic agents and to tamoxifen. To investigate whether angiogenesis predicts the clinical outcome of patients with node-positive breast cancer, we determined intratumoral microvessel density in a series of patients treated with either adjuvant hormone therapy (n=84) or chemotherapy (n= 107). PATIENTS AND METHODS: We monitored 191 patients for a median of 62 months. Intratumoral microvessel density was measured using light microscopy, and microvessels were immunostained using the anti-CD31 antibody. Microvessels were carefully counted (per 200x field) in the most vascularized area of each tumor. The results of intratumoral microvessel density were analyzed by both univariate and multivariate statistical analysis and were correlated with clinical outcome. RESULTS: In univariate analysis, intratumoral microvessel density was significantly associated with relapse-free survival and overall survival, both in patients who received adjuvant hormone therapy and those who received chemotherapy. In the group treated with adjuvant hormone therapy, estrogen receptor status was also predictive for both relapse-free and overall survival. The number of involved nodes was predictive for overall survival. In patients treated with adjuvant chemotherapy, the number of involved nodes, tumor size, and progesterone receptor status were significantly predictive for relapse-free and overall survival. Multivariate analysis showed that intratumoral microvessel density was the strongest independent predictor of outcome in both treatment groups. CONCLUSIONS: Intratumoral microvessel density is an independent predictive indicator in node-positive breast cancer patients treated with either adjuvant chemotherapy or adjuvant hormone therapy. Assessment of tumor angiogenesis may therefore be useful in selection of those patients who are more likely to benefit from conventional adjuvant therapies (i.e., those with minimally vascularized tumors) from those with highly vascularized and more aggressive tumors, for whom novel forms of systemic therapy are advocated.

Statistical considerations concerning clinical studies designed to assess DC-ARTs.

The aim of this paper is to contribute to the current ongoing debate regarding how to optimise clinical research on rheumatoid arthritis. Bearing in mind the main difficulties represented by the particular characteristics of the disease and its treatment, as well as the limitations of some of the trials that have been carried out over the last thirty years, we discuss how some of the general statistical considerations regarding all clinical trials should be applied to those specifically designed to assess disease-controlling antirheumatic therapies.
