The Ki-67 antigen is used to evaluate the proliferative activity of breast cancer (BC); however, Ki-67's role as a prognostic marker in BC is still undefined. In order to better define the prognostic value of Ki-67/MIB-1, we performed a meta-analysis of studies that evaluated the impact of Ki-67/MIB-1 on disease-free survival (DFS) and/or on overall(More)
BACKGROUND Infection with different genotypes of virulent Helicobacter pylori strains (cytotoxin-associated gene A [CagA]- and/or vacuolating cytotoxin A [VacA]-positive) can play a role in the development of atrophic gastritis, duodenal ulcer (DU) and gastric cancer (GC). OBJECTIVE To determine whether patients with GC and H pylori-negative histological(More)
Breast cancer is the most common malignant tumor affecting women. Adjuvant systemic therapies have been shown to have a significant impact on reducing the risk for breast cancer recurrence and overall mortality. Chemotherapy remains an important and frequently used treatment option in the adjuvant setting, and the associated short-term adverse events are(More)
In this study, we retrospectively evaluated the expression of vascular endothelial growth factor (VEGF) and microvessel density (MVD) in 228 and 213 specimens, respectively, from stages I and II breast cancer patients (pts) enrolled in a randomized phase III adjuvant chemotherapy trial comparing epirubicin to CMF, while tamoxifen was given to all(More)
In the last few decades, proliferative markers have been broadly evaluated as prognostic and predictive factors for early stage breast cancer patients. Several papers evaluating one or more markers have been published, often with contradictory results. As a consequence, there is still uncertainty about the role of these proliferative markers. The present(More)
BACKGROUND Adjuvant chemotherapy with anthracyclines improves disease-free and overall survival compared with non-anthracycline-based adjuvant chemotherapy regimens in the treatment of early breast cancer. The role of HER2 status as a marker of anthracycline responsiveness has been explored by subset analyses within randomized clinical trials, with(More)
BACKGROUND We explored the correlation between serum human epidermal growth factor receptor-2 (HER2) extracellular domain (ECD) and tissue HER2 status, their relationship with clinicopathological parameters and their impact on disease-free survival (DFS) and overall survival in early breast cancer patients. PATIENTS AND METHODS This prospective trial(More)
In recent decades, the use of adjuvant systemic therapies for early breast cancer has increased extensively and has most likely contributed to the decline in breast cancer mortality observed in the U.S. and in some European countries. The last few years have witnessed accelerated progress in the treatment of early breast cancer, with the introduction of(More)
The pharmacokinetics of vincristine (VCR) after an intravenous bolus dose of 2 mg were studied in patients with cancer with and without a concomitant treatment with the calcium-entry blocker nifedipine (NIF). VCR concentrations were determined by a sensitive radioimmunoassay. Pharmacokinetic data were analyzed by a nonlinear weighted least-square regression(More)
Breast cancer (BC) is the most common cancer in women and it is incurable when metastases are diagnosed. Taxanes, namely docetaxel and paclitaxel, are effective chemotherapeutic agents in the metastatic, neoadjuvant and adjuvant settings. HER-2 overexpression/amplification is detected in 25-30% of BCs and confers aggressive tumor behavior as well as(More)
