Pulmonary candidiasis in patients with cancer: An autopsy study

For patients who had cancer and autopsy-proven pneumonia, we evaluated whether cultures of respiratory secretions (sputum and/or bronchoalveolar lavage) performed less than or equal to4 weeks before autopsy were a reliable basis for the diagnosis of pulmonary candidiasis. Pulmonary candidiasis was identified at autopsy in 36 patients, but common clinical predictors were insensitive for this diagnosis. For sputum culture, the sensitivity, specificity, and the positive and negative predictive values were 85%, 60%, 42%, and 93%, respectively; for bronchoalveolar lavage culture, these values were 71%, 57%, 29%, and 89%, respectively.
