Ceftriaxone versus imipenem/cilastatin as empirical monotherapy for infections in cancer patients

We conducted a prospective randomized clinical trial to compare the efficacy and tolerability of monotherapy with ceftriaxone (active ingredient of Rocephin) (CRO) versus imipenem/cilastatin (I/C) in febrile cancer patients with or without neutropenia. 120 febrile episodes were randomized and 89 (75%) were evaluable for efficacy analysis. The overall response rates to both regimens were good (86 and 79% improved in response to CRO and I/C, respectively). Overall mortality was low and similar in the two groups. Both regimens were well tolerated. Our preliminary data corroborate the efficacy of CRO or I/C as empirical monotherapy for febrile episodes in cancer patients. It will be up to future investigations to show whether one of these regimens is superior to the other.
