An algorithm for utilizing peripheral blood CD34 count as a predictor of the need for plerixafor in autologous stem cell mobilization--cost-effectiveness analysis.

Certain patients who receive granulocyte colony-stimulating factor (GCSF) for autologous hematopoietic stem cell (AHSC) collection fail to mobilize well enough to proceed with transplant. When plerixafor is used with GCSF, the likelihood of achieving the CD34⁺ stem cell target in fewer collections is higher; plerixafor use in all patients is unlikely to be cost-effective. This study retrospectively evaluated the effectiveness of utilizing a peripheral blood CD34⁺ stem cell count (PBCD34) ≤8/µL on day 4 of GCSF-based AHSC mobilization as a threshold for plerixafor administration, and compared the efficacy of collection and cost analysis using historical controls.

18-Fluoro-deoxyglucose positron emission tomography report interpretation as predictor of outcome in diffuse large B-cell lymphoma including analysis of 'indeterminate' reports.

This study evaluates the predictive value of post-therapy 18-fluoro-deoxyglucose positron emission tomography (FDG-PET), including indeterminate studies, following curative-intent therapy in diffuse large B-cell lymphoma (DLBCL). Consecutive patients from September 2002 to December 2005 were prospectively offered enrollment in an observational registry. Available FDG-PET reports after primary therapy were interpreted by hematologist-oncologists as positive, negative, or indeterminate.
