cefepime and Lung-Neoplasms

Febrile neutropenia frequently develops after chemotherapy. There is little evidence to indicate the type of antimicrobial agents that should be used in the treatment of febrile neutropenia in patients with solid tumors. The objective is to determine the efficacy and safety of cefepime (CFPM) and meropenem (MEPM) in the treatment of febrile neutropenia in lung cancer patients in a prospective randomized study. FN patients with lung cancer were randomly divided into CFPM or MEPM groups. The primary end-point was the response rate. The secondary end-points were the defervescence rates at 72 h, 7 days, 14 days and the incidence of adverse events. Twenty-one patients were treated with CFPM and 24 patients were treated with MEPM. One patient died of FN. The CFPM treatment completion rate was 17.65% (95% CI; 0.00-35.77%), while the MEPM treatment completion rate was 38.10% (95% CI; 17.33-58.87%). The defervescence rates at 72 h, 7 days, and 14 days were 70.59%, 86.67%, and 100.00%, respectively in the CFPM group; and 65.00%, 84.21%, and 92.31% in the MEPM group. Adverse events were observed in 33.33% of the CFPM group and 45.83% of the MEPM group. The response rate of the CFPM group was 94.12% (95% CI; 73.02-98.95%), while that of the MEPM group was 85.71% (95% CI; 65.36-95.02%). No differences were found in the efficacy or safety of CFPM and MEPM in the treatment of febrile neutropenia in patients with lung cancer.

We assessed the efficacy and safety of cefepime monotherapy (1 g intravenously every 8 h) for febrile neutropenia in patients with lung cancer in a multi-institutional phase II study. Patients treated with chemotherapy with or without radiotherapy for lung cancer were eligible for this study. Other eligibility criteria included fever (temperature of ≥38.0 °C) and an absolute neutrophil count of <500/mm(3) or <1000/mm(3) with an expected decline to <500/mm(3) within the next 48 h. Risk assessment was performed using the Multinational Association of Supportive Care in Cancer risk-index score. Cefepime 1 g was given intravenously every 8 h. The primary endpoint was the response rate at the end of cefepime therapy. Co-administration of granulocyte-colony-stimulating factor was permitted. Of 54 patients enrolled, 39 were classified in the low-risk group and 15 in the high-risk group. Overall response rate was 78% (95% CI: 64.4-88.0%). The response rates were 85% (95% CI: 69.5-94.1%) in the low-risk group and 60% (95% CI: 32.3-83.7%) in the high-risk group, respectively. One patient died from septic shock due to Enterobacter cloacae bacteremia. There was no significant adverse event. Cefepime 1 g intravenously every 8 h appears to be effective for febrile neutropenia in patients with lung cancer, especially in those with low-risk febrile neutropenia, and is well tolerated..

Fever often occurs along with chemotherapy-induced neutropenia. This condition is referred to as febrile neutropenia (FN). Excellent guidelines for FN treatment have recently been published; however, there has so far been insufficient research concerning FN associated with solid tumors, especially in Japan. A multi-institution prospective study of cefepime for the treatment of FN in lung cancer patients was conducted. The objective of this study was to determine the efficacy and safety of cefepime for FN in lung cancer patients. Cefepime (2 g x 2/day) was administered to patients with FN after treatment for lung cancer. The therapeutic response rate, the effect of the drug on pathogen populations, and the incidence of adverse effects were statistically analyzed. Twenty-one patients with FN were registered for this study. One case was excluded because of protocol violation; therefore, a total of 20 cases were analyzed. Three days after the administration of cefepime, improvement was evident in 15 cases. The response rate was 75%, 95% CI: 53.1-88.8. After 7 days, 17 patients experienced improvement in their condition (85%, 95% CI: 64.0-94.8). Carbapenem was eventually substituted for cefepime in three cases, and all cases finally displayed improvement. There was no mortality. Pathogens for FN were detected in three cases and they disappeared in one case. Four patients experienced adverse side effects, including skin eruption, serum bilirubin elevation, neutrophil depletion, and anterior chest pain. There were no severe adverse events. In this study, cefepime demonstrated a high degree of clinical efficacy and safety in the treatment of FN. Empiric monotherapy using cefepime is a recommended regimen for FN in patients with lung cancer in Japan.

Febrile neutropenia (FN) is a serious side effect in patients undergoing cancer chemotherapy and frequently proves fatal. Since infection control is crucial in the management of FN, the antimicrobial agent cefozopran (CZOP) has been recommended but not approved for routine use in clinical care of FN in Japan. However, few studies of CZOP in the management of FN have used a thrice daily dose schedule. The aim of this study was to retrospectively compare the efficacy and safety of CZOP at a dose of 1 g three times daily to those of cefepime (CFPM) in the treatment of FN in our lung cancer patients. The response rates of the CZOP and CFPM groups were 89.5% (17/19 cases) and 83.0% (39/47 cases), respectively, with no significant difference between the two groups. The median duration of antimicrobial treatment was 6 days (4-10 days) in the CZOP group and 7 days (3-13 days) in the CFPM group, with no significant difference between groups. The incidence rates of adverse events were 21.1% (4/19 cases) in the CZOP group and 19.1% (9/47 cases) in the CFPM group. No adverse events of Grade 3 or higher were observed in either group. The findings of the present study suggest that CZOP administration at a dose of 1 g three times per day as an antimicrobial treatment alternative against FN.
