title: Pneumocystis carinii pneumonia among patients without AIDS at a cancer hospital.
abstract: OBJECTIVE
  To determine the predisposing factors, attack rate by underlying disease, and outcome of Pneumocystis carinii pneumonia among patients without the acquired immunodeficiency syndrome (AIDS) at a cancer center.
  
  
  METHODS
  Twelve-year retrospective review from a tertiary-care cancer center.
  
  
  METHODS
  One hundred forty patients, constituting 142 cases, with morphologically proved P carinii pneumonia.
  
  
  RESULTS
  Hematologic malignancy (47%) (including lymphoma [27%] and leukemia [18%]), solid tumor (31%), or bone marrow transplantation (18%) was the underlying condition in the majority of cases. Twenty-five cases (18%) were diagnosed at autopsy. All but seven patients had previously established predisposing factors for P carinii pneumonia, including corticosteroid use in 87%. The attack rate for hospitalized patients with primary or metastatic brain tumor increased during the 12-year interval. The attack rates for hospitalized patients with hematologic neoplasm or bone marrow transplantation were stable. The overall mortality rate did not change during the period reviewed.
  
  
  CONCLUSIONS
  Despite the availability of effective prophylaxis, P carinii pneumonia continues to occur among patients with neoplastic disease. In addition to patients with certain hematologic neoplasms, those with primary or metastatic brain neoplasm who receive corticosteroids are at risk for the development of P carinii pneumonia and should receive P carinii pneumonia prophylaxis.
