ANC > 100 /mm3 Normal CXR Duration of neutropenia < 7 d Resolution of neutropenia <10 d No appearance of illness No comorbidity complications Malignancy in remission 4 Walter at al, Infect Desease Society of America. 2002; 34: Hughes at al, Clin Infect Diss 2002; 52:

Bacterial infection Neutropenia :single most important risk factor for infection in cancer. Risk of infection increases 10-fold with declining neutrophil counts < 500/mm % : occult infection 16-20% with neutropenia<100/mm3 have bacteremia 10 Samam MD. Commun Oncol 2006; 3 :

Broad spectrum of bactericidal activity Local prevalence, susceptibility pattern Antibiotic toxicity : well-tolerated, allergy Host factors : severity of presentation Prior antibiotic usage Antibiotic costs Ease of administration 11

1. Monotherapy Antipseudomonal Ceph 3 : ceftazidime Ceph 4 : cefepime Carbapenem : imipenem, meropenem 2. Combination Duo therapy without vancomycin Vancomycin plus one or two drugs 12 Lindbad et al, Scand J Infect Dis. 2005; 30: Liat V et al, J Antimimicrobial Chem. 2004; 54:29-31 Hughest et al, Guideline for febrile neutropenia. 2002; 34:

Persistence of fever Clinical deterioration Culture results Drug intolerance/side effects 15

Increased bactericidal activity Potential synergistic effects Broader antibacterial spectrum Limits emergence of resistance 16

Drug toxicities Drug interactions Potential cost increase Administration time 17

Significant morbidity & mortality Choice of initial empiric therapy dependent on epidemiologic & clinical factors Monotherapy as efficacious as combination Rx Modifications upon reassessment Duration dependent on ANC 27
