BACKGROUND The outcome of children with refractory/relapsed malignancies remains poor and novel therapies are urgently required. One of the promising approaches is metronomic chemotherapy. We present the clinical results of 74 children with advanced solid tumors treated according to treatment recommendation with data registry in three European pediatric(More)
CD3+ CD56+ NKT-like cells have been shown to produce substantial amounts of pro-inflammatory cytokines and to mediate lysis of malignant cells. Using flow cytometry, we evaluated the absolute NKT-like cell count in peripheral blood from individuals in a reference population and the median number was 0.085 x 10(9)/l. The average number of NKT-like cells in(More)
Vitamin D deficiency has been implicated in the epidemiology of common malignancies including colorectal cancer. We studied consecutive blood levels of 25-hydroxycholecalciferol (25-OHD) in relation to other clinical and laboratory variables in metastatic colorectal cancer patients to ascertain whether their variations may be prognostic or predictive(More)
The majority of patients with breast carcinoma receive chemotherapy as a component of multimodality treatment. Over the past decade, it has become increasingly more common to deliver chemotherapy first, but this has raised new questions within all disciplines of cancer management. However, the effect of cytotoxic treatment cannot be predicted on(More)
BACKGROUND To evaluate the influence of pretreatment plasma folate concentrations on methotrexate exposure in children with acute lymphoblastic leukemia/non-Hodgkin lymphoma treated with high-dose methotrexate, we assessed time profiles of plasma homocysteine, folate, and vitamin B(12) concentrations in children treated with high-dose methotrexate with(More)
Plasma homocysteine has recently been associated with the occurrence of methotrexate-related neurotoxicity. We observed extreme elevations of homocysteine in a 9-year-old boy presenting with leukemia treated with the ALL-BFM 95 protocol. Coma occurred at about the 71st hour from the first methotrexate administration, and lasted for 30 h but MRI and CT(More)
Background. Sunitinib is a tyrosine kinase inhibitor used in the treatment of metastatic renal cell carcinoma. The main difficulty related to the treatment is the development of drug resistance followed by rapid progression of the disease. We analyzed tumor tissue of sunitinib treated patients in order to find miRNAs associated with therapeutic response.(More)
OBJECTIVE Metabolic adverse effects of atypical antipsychotics (AAP) contribute significantly to increased risk of cardiovascular morbidity and mortality in patients suffering from schizophrenia. Extensive preclinical research has addressed this issue over the past years, though mechanisms underlying these adverse effects of AAP are still not understood(More)
With the recent addition of anti-angiogenic agents to cancer treatment, the angiogenesis regulators in platelets are gaining importance. Platelet factor 4 (PF-4/CXCL4) and Connective tissue activating peptide III (CTAP-III) are two platelet-associated chemokines that modulate tumor angiogenesis, inflammation within the tumor microenvironment, and in turn(More)
Monoclonal antibody-based treatment of cancer has been established as one of the most successful therapeutic strategies for both hematologic malignancies and solid tumors. In addition to targeting cancer antigens antibodies can also modulate immunological pathways that are critical to immune surveillance. Antibody therapy directed against several negative(More)
