This was a retrospective chart review of patients with chemotherapy related anemia. Two hundred (200) patients with chemotherapy related anemia were to have received PROCRIT (Epoetin alfa) on a weekly schedule (e.g., once every week or more frequently) for at least 4 weeks, followed by a maintenance PROCRIT (Epoetin alfa) schedule of less frequent dosing (e.g. once every 2 weeks, once every 3 weeks, or once every 4 weeks) for at least 6 weeks. Hemoglobin response and maintenance of initial treatment phase hemoglobin with alternate doses of PROCRIT (Epoetin alfa) were to be evaluated.Study sites were to record data in a Case Report Form which would then be entered into a database. Data was to be recorded, starting with the PROCRIT (Epoetin alfa) initiation phase (at least 4 weeks duration), and extending through at least 6 weeks of maintenance therapy. A minimum of 20 study sites were to be enrolled in the data collection process.Data obtained was to be analyzed to reflect alternate dosing patterns of PROCRIT (Epoetin alfa) therapy. The frequency and percentage of patients receiving each dosing regimen were to be summarized. Hemoglobin response and maintenance of initial treatment phase hemoglobin with alternate doses of PROCRIT (Epoetin alfa) were to be evaluated. If PROCRIT (Epoetin alfa) was discontinued, the time and reason(s) for discontinuation were to be recorded.
