Abstract:
OBJECTIVE:To investigate the characters of infection in patients with malignant tumors, especially the distribution, yearly change of pathogens, and pathogen resistance to common antibacterial agents.
METHODS:We respectively analyzed the characters of infection in 489 patients with malignant tumors.
RESULTS:The respiratory tract was the most frequent infection site (61.1%). The infection was mainly caused by opportunistic pathogens. The Gram-negative bacterias mainly consisted of Pseudomonas aeruginosa, Escherichia coli, and Acinetobacter baumannii (46.3%). The Gram-positive bacteria mainly consisted of Staphylococcus aureus and Staphylococcus epidermidis (29.9%), and the rest 23.8% of the infection was caused by different fungi, mainly consisting of Candida albicans. The ratio of the Gram-negative bacteria resistance to antibiotics such as penicillins, cephalosporins (except ceftazidime), sulfanilamides, tetracyclines and quinolones was higher. The ratio of the Gram-positive bacteria resistance to antibiotics such as penicillins, macrolides and quinolones was higher. The ratio of fungus resistance to antibacterial agents such as fluconazol and itraconazole was higher. The infection caused by fungi obviously increased in the past 5 years.
CONCLUSION:The infection in patients with malignant tumors is mainly caused by opportunistic pathogens, and the pathogen resistance to antibacterial agents is serious. The infection caused by fungi is increasing.
