Outpatient management without initial assessment for febrile patients undergoing adjuvant chemotherapy for breast cancer.

The purpose of this study was to retrospectively analyze the feasibility of outpatient management without initial assessment for febrile patients undergoing adjuvant chemotherapy for breast cancer. A total of 131 consecutive patients with breast cancer treated with adjuvant or neoadjuvant chemotherapy from 2011 to 2013 at Osaka Medical College Hospital (Osaka, Japan) were retrospectively reviewed. In the case of developing a fever (body temperature, ≥38°C), the outpatients had been instructed to take previously prescribed oral antibiotics for 3 days without any initial assessment, and if no improvement had occurred by then, they were required to visit the hospital for examination and to undergo treatment based on the results of a risk assessment for complications. The primary aim of the present study was to assess the outcome of febrile episodes, while the secondary aim was to assess the incidence of febrile episodes, hospitalizations, and the type of chemotherapy. The 131 patients received 840 chemotherapy administrations. Fifty-five patients (42.0%) had a total of 75 febrile episodes after 840 chemotherapy administrations (8.9%). Treatment failure occurred in 12 of the 75 episodes (16.0%) in 11 of the 55 patients (20.0%). Only four episodes required hospitalization. Treatment success was achieved in 63 episodes (84.0%). In conclusion, the feasibility of outpatient management without initial assessment was evaluated in the present study for febrile patients undergoing adjuvant chemotherapy for breast cancer, and the outpatient strategy regimen may be safe and convenient for these patients.
