【Abstract】 Objective To examine the epidemic tendency and the correlated factors related to such tendency about fungal infection in respiratory tract of lung cancer patients.Methods One thousand two hundreds and ninety six hospitalized patients with lung cancer during the period of January 1987 through December 2001 were sampled retrospectively for the study. The patients were classified into subgroups based on their age, sex, and methods of treatment. Prevalence and incidence rates and causes of fungal infection in airway were analyzed accordingly. The data were processed by statistical methods.Results Out of the 1296 patients, 78 (6.0%) were identified as infected with fungus in the airway. The difference of infective rates between man and woman (7.0% and 3.9%, respectively for man and woman groups: p < 0.05), but was not significant (p >0.05) among the age groups and between the operation and non operation groups (6.6% and 5.5%, respectively for the two groups: p>0.05). For the operation group, the patients who had received chemotherapy either before or in the operation had significantly higher infection rate than those who did not receive the chemotherapy: 9.8% vs. 5.2%, p <0.05). For the non operation group, those who received chemotherapy or a combination of chemotherapy and radiotherapy had a higher infection rate than those who received the radiotherapy only: 7.6% vs. 2.6%, p <0.01) and those who received other types of treatment: 7.6% vs. 3.4%, p<0.01). A significantly higher percent of infective patients used antibiotics compared to the uninfective patients: 97.4% vs. 63.3%, p <0.01. Conclusion The fungal infection in respiratory tract of lung cancer patients is related to the use of chemotherapy and wide use of antibiotics for a long time. It is not associated with the patients’ age and the status of the operation.更多还原
