Treatment of nosocomial postoperative pneumonia in cancer patients: a prospective randomized study.
BACKGROUND
Nosocomial pneumonia continues to be associated with high morbidity and mortality in cancer patients.


METHODS
In an attempt to find an optimal treatment for this infection, nonneutropenic cancer patients with postoperative nosocomial pneumonia were randomized to receive either piperacillin/tazobactam (P/T) 4.5 g i.v. every 6 hours (30 patients) or clindamycin (Cl) 900 mg plus aztreonam (Az) 2 g i.v. every 8 hours (22 patients). Amikacin 500 mg i.v. every 12 hours was given to all patients for the first 48 hours.


RESULTS
The two groups were comparable for the characteristics of pneumonia that included gram-negative etiology and duration of intubation. Response rates were 83% for patients who received P/T and 86% for those who received Cl/Az (P > .99). There were no serious adverse events; however, at our center the cost of the P/T regimen was $73.86 compared with $99.15 for the Cl/Az regimen.


CONCLUSIONS
The two regimens had comparable high efficacy, and P/T had a slight cost advantage. Either of these antibiotic regimens combined with an aminoglycoside could lead to favorable outcome in cancer patients at high risk for nosocomial pneumonia.
