OBJECTIVE To study the frequency of fungal infection and its drug resistance in tumor patients, and to provide the reference for clinical treatment. METHODS From Aug 2006 to Jul 2008, the drug sensitivity test and pathogen distribution of 960 patients in our hospital were retrospectively analyzed. RESULTS A total of 308 fungal strains were detected from 960 patients (32.1%). Candida albicans infection rate reached 73.1%, and C. krusei and C. glabrata were 13.3% and 9.1%, respectively. Drug sensitivity showed that the drug resistance of C. albicans to ECC, KET and MIC was 43.9%, 34.2 and 27.1%, respectively, and that of the C. krusei to the ECC, KET and MIC were 53.3%, 42.2% and 48.8%, respectively, while their fungal infection was depressed by AMB, NYS and 5-FC. CONCLUSIONS C. albicans is the major fungus in patients of tumor hospital, and the infection rate of C. krusei and C. glabrata is also high. Clinical doctors should control the distribution and drug resistance of fungal infection in therapeutic process for a reasonable antibiotics usage.
