Although pyrexia caused by neutropenia is relatively uncommon in cancer treatment patients, an understanding of the level and extent of treatment needed for this condition would help in case management. In this paper, 70 hospitalized febrile and neutropenic dogs (neutrophil count <2500 cells/µL, rectal temperature >102.5°F) with various cancers and in different stages of treatment were retrospectively selected. Body temperature, neutrophil count, adverse clinical signs, infections, prophylactic antibiotic use, and other variables were noted.
Progressive clinical signs and neutropenia were linked to length of hospital stay but not mortality. Tachycardia (>120 bpm) at admission, decreasing neutrophil acount after admission, and complicating medical issues were both associated with a prolonged hospital stay. Hypotension (systolic bp <90 mmHg or MAP <60 mmHg) was a significant risk factor for dying in-hospital.
The authors recommend future studies with greater numbers to assess what level of hospitalized care is ultimately necessary rather than giving all patients the same degree of intensive care.
