A Study of Neutropenia and Anemia Management in Patients With Solid Tumors Receiving Myelotoxic Chemotherapy
A Prospective Observational Study of Neutropenia and Anemia Management in Subjects With Solid Tumors Receiving Myelotoxic Chemotherapy
Study Overview
Status
Detailed Description
This is a multi-center international observational study of patients receiving myelotoxic regimens, with an investigator assessed risk of febrile neutropenia ≥ 20%, for the treatment of solid tumors (breast, ovarian and lung).
This is an observational study in which patient risk factors were qualitatively (but not quantitatively) assessed, and adherence to G-CSF primary prophylaxis was at the discretion of physicians and not mandated by the protocol.

Time Frame |
---|---|---|
Percentage of Participants With Febrile Neutropenia (FN)
Time Frame: Cycles 1 - 8 (approximately 24 weeks)
|
Febrile neutropenia was defined as a single oral temperature ≥ 38.3°C, or a temperature of ≥ 38.0°C for ≥ 1 hour with a neutrophil count of < 500 cells/mm² or < 1000 cells/mm² and predicted to fall below 500 cells/mm².
|
Cycles 1 - 8 (approximately 24 weeks)
|
Percentage of Participants Who Received No Prophylaxis or Treatment With Granulocyte Colony-stimulating Factors (G-CSF) Who Experienced Febrile Neutropenia

Primary prophylaxis with pegfilgrastim was defined as receiving pegfilgrastim starting in cycle 1 on day 1 to 7 if chemotherapy completed by day 7 and day 1 to 11 if chemotherapy completed after day 7. Assignment to G-CSF use groups was programmatically derived rather than assigned by the investigator.
Participants were assigned to a G-CSF use group that represented the 'best' G-CSF therapy they received at any point in the study.
