Abstract:
Objective To investigate the clinical distribution and drug-susceptibility characteristics of yeast speeies in tumor patients with invasive yeast infections in order to provide the gist for clinical therapy.Methods The medical records of 70 tumor patients with invasive yeast infections from January 2006 to December 2008 were collected.retrospectively.The relationship between different tumor types and invasive yeast infections was analyzed.The clinical distribution and drug-susceptibility characteristics of 70 isolates of yeast were investigated.Results The sites of invasive yeast infections were abdominal(32 cases),blood(18 cases),biliary(9 cases),central nervous system(6 cases)and chest infection(5 cases).respectively.The most common species causing the above infections was Candida albicans(34 isolates,48.6%).The mortality of invasive yeast infection was 15.7%.The main types of tumor in 70 patients with invasive yeast infections were pancreatic carcinoma(12 cases),stomach carcinoma(11 cases)and hepatocellular carcinoma(7 cases).No relationship was found between tumor types and yeast infections with different species(P=0.804,P>0.05).There were 18 patients with tumor metastasis.Among them.9 patients had yeast bloodstream infections and 6 with yeast abdominal infections.Yeast bloodstream infections were more likely to be found in patients with tumor metastasis(χ~2=5.357,P<0.05).Seventy isolates of yeasts were all sensitive to triazoles.The MIC values of amphotericin B aginst 6 isolates of Candida and 2 Laurent cryptococcal were 2μg/ml.Conclusion Patients with tumor metastasis should be paid more attention for yeast invasive infections.and triazoles kept activity against yeasts tested.
