A combination of amikacin and ceftazidime was used as initial empiric therapy for the treatment of 25 evaluable febrile episodes (temperature greater than or equal to 38.5 degrees C) in leukopenic adult patients (wbc less than or equal to 1,000/mm3) with solid tumors, characterized by poor prognosis because of low performance status (median Karnofsky score: 50) and progressive disease (76% of cases). Nineteen (76%) of the 25 episodes responded to the initial empiric antibiotic combination. In the microbiologically documented infections, there was no significant difference in the response rate between bacteremia (67%) and localized infections (81%). The response in localized infections caused by gram-negative organisms (81%) was similar to that obtained in gram-positive organisms (82%), whereas gram-positive bacteremia responded better than gram-negative (100 vs 50%). No serious side effects were observed. Reversible nephrotoxicity occurred in 12% and hypokalemia in 20% of the patients treated. This antibiotic combination is a safe and efficacious empiric therapy for infections in leukopenic patients with solid neoplasia.
