What regimen FN risk threshold requires G-CSF prophylaxis?

G-CSF primary prophylaxis is recommended when the combined regimen plus patient risk of febrile neutropenia exceeds 20%. Regimen FN risk 10–20% (intermediate): add G-CSF if patient risk factors (age above 65, poor PS, renal/hepatic impairment, HIV) are present.
