Multiple courses of G-CSF in patients with decompensated cirrhosis: consistent mobilization of immature cells expressing hepatocyte markers and exploratory clinical evaluation.

Introduction: Bone marrow-derived cells (BMCs) include stem cells capable of self-renewal and differentiation into a variety of cell types. Administration of granulocyte colony-stimulating factor (G-CSF) induces the circulation of BMCs in the peripheral blood. A phase II prospective trial was carried out for evaluation of BMC mobilization induced by multiple courses of G-CSF in cirrhotic patients.

Repeated courses of granulocyte colony-stimulating factor in amyotrophic lateral sclerosis: clinical and biological results from a prospective multicenter study.

Granulocyte colony-stimulating factor (G-CSF) induces a transient mobilization of hematopoietic progenitor cells from bone marrow to peripheral blood. Our aim was to evaluate safety of repeated courses of G-CSF in patients with amyotrophic lateral sclerosis (ALS), assessing disease progression and changes in chemokine and cytokine levels in serum and cerebrospinal fluid (CSF). Twenty-four ALS patients entered an open-label, multicenter trial in which four courses of G-CSF and mannitol were administered at 3-month intervals.

High-dose ara-C with autologous peripheral blood progenitor cell support induces a marked progenitor cell mobilization: an indication for patients at risk for low mobilization.

A high-dose (HD) chemotherapy scheme was designed for the collection of large numbers of peripheral blood progenitor cells (PBPC) in lymphoma patients who were candidates for myeloablative therapy with autograft. The scheme included the sequential administration of HD cyclophosphamide (CY) (7 g/m(2)) and HD ara-C (2 g/m(2) twice a day for 6 consecutive days), followed by final consolidation with PBPC autograft. PBPC harvests were scheduled following both HD CY and HD ara-C.

Feasibility of peripheral blood progenitor cell mobilization and harvest to support chemotherapy intensification in elderly patients with poor prognosis: non-Hodgkin's lymphoma.

Mobilized peripheral blood progenitor cells (PBPC) are widely employed in the management of adult patients with high-risk non-Hodgkin's lymphoma (NHL), though their use in the elderly has received little attention. This study was mounted to assess the feasibility of the mobilization, harvesting, and reinfusion of PBPC in NHL patients aged >60. Twenty patients (median age: 67, range: 61-80) with poor-prognosis NHL entered the pilot study: nine others were discarded for various reasons.

Concurrent administration of high-dose chemotherapy and rituximab is a feasible and effective chemo/immunotherapy for patients with high-risk non-Hodgkin's lymphoma.

The aim of this study was to investigate feasibility, tolerability and efficacy of rituximab-supplemented high-dose sequential chemotherapy (R-HDS) with peripheral blood progenitor cell autografting as frontline or salvage treatment in patients with advanced non-Hodgkin's lymphoma (NHL). Thirty-two patients have been treated: 14 at disease onset and 18 with relapsed or progressive disease. R-HDS regimens included six courses of rituximab.
