Aggressive chemotherapy combined with G-CSF and maintenance therapy with interleukin-2 for patients with advanced myelodysplastic syndrome, subacute …
1993
Aggressive chemotherapy of advanced myelodysplastic syndrome (MDS), acute myeloid leukemia (AML) evolving from MDS, subacute AML and secondary AML has usually been associated with low complete remission (CR) rates, a high incidence of early death, and low disease-free survival. We therefore have initiated a phase-III trial of aggressive chemotherapy consisting of idarubicin, cytosine arabinoside, and VP-16 to improve the CR rate. Each chemotherapy cycle is followed by G-CSF to accelerate neutrophil recovery and to reduce the incidence of infections. Until now, 19 patients with high-risk AML have been entered. The CR rate is 47%, with only one death during induction. Patients achieving CR ar…
Gemcitabine, oxaliplatin, levofolinate, 5-fluorouracil, granulocyte-macrophage colony-stimulating factor, and interleukin-2 (GOLFIG) versus FOLFOX ch…
2013
The GOLFIG-2 phase III trial was designed to compare the immunobiological activity and antitumor efficacy of GOLFIG chemoimmunotherapy regimen with standard FOLFOX-4 chemotherapy in frontline treatment of metastatic colorectal cancer (mCRC) patients. This trial was conceived on the basis of previous evidence of antitumor and immunomodulating activity of the GOLFIG regimen in mCRC. GOLFIG-2 is a multicentric open/ label phase III trial (EUDRACT: 2005-003458-81). Chemo-naive mCRC patients were randomized in a 1:1 ratio to receive biweekly standard FOLFOX-4 or GOLFIG [gemcitabine (1000 mg/m 2, day 1); oxaliplatin (85 mg/m2, day 2); levofolinate (100 mg/m2, days 1-2), 5-fluorouracil (5-FU) (400…
Exposure to UV radiation and risk of Hodgkin lymphoma: A pooled analysis
2013
Ultraviolet radiation (UVR) exposure has been inversely associated with Hodgkin lymphoma (HL) risk, but only inconsistently, only in a few studies, and without attention to HL heterogeneity. We conducted a pooled analysis of HL risk focusing on type and timing of UVR exposure and on disease subtypes by age, histology, and tumor-cell Epstein-Barr virus (EBV) status. Four case-control studies contributed 1320HLcasesand 6381 controls. We estimated lifetime, adulthood, and childhood UVR exposure and history of sunburn and sunlamp use. We used 2-stage estimation with mixed-effects models and weighted pooled effect estimates by inverse marginal variances. We observed statistically significant inv…
G-CSF (filgrastim) treatment for amyotrophic lateral sclerosis: protocol for a phase II randomised, double-blind, placebo-controlled, parallel group,…
2020
IntroductionAmyotrophic lateral sclerosis (ALS) is a fatal progressive neurological disorder characterised by a selective degeneration of motor neurons (MNs). Stem cell transplantation is considered as a promising strategy in neurological disorders therapy and the possibility of inducing bone marrow cells (BMCs) to circulate in the peripheral blood is suggested to investigate stem cells migration in degenerated ALS nerve tissues where potentially repair MN damage. Granulocyte-colony stimulating factor (G-CSF) is a growth factor which stimulates haematopoietic progenitor cells, mobilises BMCs into injured brain and it is itself a neurotrophic factor for MN. G-CSF safety in humans has been de…
Effect of Treatment with rhGM-CSF and Low-Dose Cytosine Arabinoside on Leukemic Blast Cells in Patients with Myelodysplastic Syndromes
1990
Treatment of patients having myelodysplastic a syndromes (MDS) with approaches such as differentiation induction, single cytostatic agents or supportive care only has, up to now, been rather unsuccessful. Aggressive chemotherapy followed by bone marrow transplantation is only suitable for a very small proportion of patients. Thus, there is a need for new therapeutic alternatives.
GM-CSF in a Double-Blind Randomized Placebo-Controlled Trial in Therapy of Adult Patients with De Novo Acute Myeloid Leukemia
1994
Despite the fact that 60%–70% of patients with de novo acute myeloblastic leukemia (AML) achieve a complete remission (CR) of the disease only about 20%–30% of the patients remain in long term remission and are probably cured [1,2]. These rather disappointing long-term results argue in favor of an even more intensive induction and post-remission therapy. This intention is, however, at time limited by therapy associated toxicity. Especially haematotoxicity seems to be the limiting factor in that patients with profound neutropenia are at high risk of developing fatal infectious complications [3]. In this context haematopoietic growth factors, such as granulocyte-macrophage colony-stimulating …
Effect of Granulocyte-Macrophage Colony-Stimulating Factor on Neutropenia and Related Morbidity Induced by Myelotoxic Chemotherapy
1990
Myelosuppression-related neutropenia is the major side effect of most anticancer chemotherapy. Despite considerable improvements in supportive care due to the advent of a variety of new antibiotic combinations, infection remains the main risk arising during the neutropenic period that follows intensive chemotherapy for cancer [1]. In addition, neutropenia is the major obstacle to dose escalation, frequency of cytoreductive treatment, and thus to improved cancer control. Regarding reduction of the period of neutropenia and increase of the maximum tolerated dose of effective anticancer agents, autologous bone marrow transplantation (ABMT) has recently offered new promise. However, as many as …
Neuroprotective Potential of GDF11: Myth or Reality?
2019
In the brain, aging is accompanied by cellular and functional deficiencies that promote vulnerability to neurodegenerative disorders. In blood plasma from young and old animals, various factors such as growth differentiation factor 11 (GDF11), whose levels are elevated in young animals, have been identified. The blood concentrations of these factors appear to be inversely correlated with the age-related decline of neurogenesis. The identification of GDF11 as a “rejuvenating factor” opens up perspectives for the treatment of neurodegenerative diseases. As a pro-neurogenic and pro-angiogenic agent, GDF11 may constitute a basis for novel therapeutic strategies.
Oscillation results for second-order nonlinear neutral differential equations
2013
Published version of an article in the journal: Advances in Difference Equations. Also available from the publisher at: http://dx.doi.org/10.1186/1687-1847-2013-336 Open Access We obtain several oscillation criteria for a class of second-order nonlinear neutral differential equations. New theorems extend a number of related results reported in the literature and can be used in cases where known theorems fail to apply. Two illustrative examples are provided.
Stem cell-secreted factor therapy regenerates the ovarian niche and rescues follicles.
2021
Background Ovarian senescence is a normal age-associated phenomenon, but increasingly younger women are affected by diminished ovarian reserves or premature ovarian insufficiency. There is an urgent need for developing therapies to improve ovarian function in these patients. In this context, previous studies suggest that stem cell–secreted factors could have regenerative properties in the ovaries. Objective This study aimed to test the ability of various human plasma sources, enriched in stem cell–secreted factors, and the mechanisms behind their regenerative properties, to repair ovarian damage and to promote follicular development. Study Design In the first phase, the effects of human pla…
