Vascular endothelial growth factor (VEGF) inhibits differentiation and maturation of dendritic cells (DC), suggesting a potential immunosuppressive role for this proangiogenic factor. Bevacizumab, sorafenib and sunitinib target VEGF-mediated angiogenesis and are active against several types of cancer, but their effects on the immune system are poorly(More)
BACKGROUND Several drugs are available to treat metastatic renal-cell carcinoma (MRCC), and predictive markers to identify the most adequate treatment for each patient are needed. Our objective was to identify potential predictive markers of sunitinib activity in MRCC. METHODS We collected sequential serum samples from 31 patients treated with sunitinib.(More)
The introduction of targeted therapy represents a major advance in the treatment of tumor progression. Targeted agents are a novel therapeutic approach developed to disrupt different cellular signaling pathways. The tyrosine kinase inhibitor sunitinib specifically blocks multiple tyrosine kinase receptors that are involved in the progression of many tumors.(More)
Cancer may occur as a result of abnormal host immune system tolerance. Recent studies have confirmed the occurrence of spontaneous and induced antitumor immune responses expressed as the presence of tumor-infiltrating T cells in the tumor microenvironment in some cancer models. This finding has been recognized as a good prognostic factor in several types of(More)
Neutropenia is a frequent adverse event of the pharmacologic treatment of cancer. Morbidity and mortality-associated neutropenia can be successfully treated and prevented with granulocyte-colony stimulating factors (G-CSF). European and American Guidelines recommend their prophylactic use when the expected percentage of febrile neutropenia exceeds 20% or(More)
5113 Background: Several drugs are available for treatment of MRCC and predictive markers to select the most appropriate therapy for each patient are needed to improve efficacy and to avoid unnecessary toxicities and costs. METHODS Serum samples were collected prospectively in 31 patients treated with sunitinib at baseline and at the time of response(More)
