Treatment of malignancy |
| Risk is higher with regimens that include:
| |
|
| ||
|
| ||
|
| ANC <100/mcL for ≥7 days[19-21] | |
| ALC <700/mcL (ANC surrogate)[11,22] | ||
| AMC <150/mcL (ANC surrogate)[23] |
ALC: absolute lymphocyte count; AMC: absolute monocyte count; ANC: absolute neutrophil count; CR: complete response; ECOG: Eastern Cooperative Oncology Group; GI: gastrointestinal; MDS: myelodysplastic syndrome; NCI: National Cancer Institute; NHL: non-Hodgkin lymphoma; OMAS: oral mucositis assessment scale; PR: partial response.
* Grade 3 and 4 neutropenia. Treatment included colony-stimulating factors and antimicrobial prophylaxis. Rate of neutropenia varied by chemotherapy regimen.Reproduced with permission from: Taplitz RA, Kennedy EB, Bow EJ, et al.
