Comparison of pegfilgrastim prescribing practice to national guidelines at a university hospital outpatient oncology clinic.

Purpose: Pegfilgrastim reduces the risk of febrile neutropenia (FN) and is indicated as primary prophylaxis when the risk of FN approaches 20% in each chemotherapy cycle. There have been few reports evaluating the appropriate use of pegfilgrastim in comparison with published guidelines. We sought to determine possible over-prescribing as a way to maintain quality and reduce cost.

Favorable outcomes in patients with high donor-derived T cell count after in vivo T cell-depleted reduced-intensity allogeneic stem cell transplantation.

Patients with hematologic malignancies were conditioned using a rabbit antithymocyte globulin-based reduced-intensity conditioning regimen for allogeneic stem cell transplantation. Donor-derived CD3(+) cell count (ddCD3), a product of CD3(+) cell chimerism and absolute CD3(+) cell count, when <110/μL at 8 weeks post-stem cell transplantation predicted a high risk of sustained mixed chimerism and relapse. Alternatively, patients with a higher ddCD3 developed graft-versus-host disease more frequently, and when partially chimeric, had higher rates of conversion to full donor chimerism after withdrawal of immunosuppression.

Ipilimumab: a novel treatment for metastatic melanoma.

Objective: To review the mechanism of action, pharmacokinetics, efficacy, safety, drug interactions, dosing, and economic considerations of ipilimumab.

Data Sources: A literature search using MEDLINE (1966-November 2010) was performed using the terms ipilimumab, metastatic melanoma, MDX-010, and MDX-101. Additional data were obtained from meeting abstracts, bibliographies, and media releases.
