| Abstract: | The IDSA guideline for management of febrile neutropenic patients updated in 2010 recommends monotherapy with anti-pseudomonal-lactam agents, including piperacillin-tazobactam (PIPC/TAZ) for high-risk patients. However, clinical studies of PIPC/TAZ are limited in Japanese patients. In this study, we conducted an open-labeled non-randomized prospective trial to examine the efficacy and safety of PIPC/TAZ as an empirical treatment for Japanese patients with febrile neutropenia. Forty-nine febrile episodes in neutropenic patients excluding those undergoing allogeneic stem cell transplantation (high risk 36, low risk 13) were analyzed. The overall response rate was 71%, and no significant differences between the high-risk and the low-risk group were observed (high risk 72%, low risk 69%). Neither PS nor usage of G-CSF affected the response rate. No major side effects were observed in the study. The efficacy and the safety profile of PIPC/TAZ treatment were comparable to those in other previous Western studies. In conclusion, this study suggests PIPC/TAZ is effective and well tolerated as an initial empirical treatment for febrile neutropenic Japanese patients. |
