title: Hepatic abscess in cancer patients. Characterization and management.
abstract: OBJECTIVE
  To identify factors that may aid in the diagnosis and treatment of patients with malignant neoplasms in whom hepatic abscesses develop.
  
  
  METHODS
  Retrospective review of medical records.
  
  
  METHODS
  Thirty-seven oncology patients in whom hepatic abscesses developed at the National Cancer Institute, Bethesda, Md, between June 1954 and October 1989.
  
  
  RESULTS
  Among 37 cancer patients, bacterial abscesses developed in 17 and fungal abscesses developed in 20. Among the patients with bacterial abscesses, 12 (71%) had a solid-tissue malignant neoplasm, 10 (59%) had a prior invasive procedure, and six (35%) had prior chemotherapy. In comparison, among the patients with fungal abscesses, 15 (75%) had a hematologic malignant neoplasm and five (25%) had a solid-tissue malignant neoplasm (P2 = .014). Two patients with fungal abscesses (10%) had a prior invasive procedure (P2 = .004) and 19 (95%) had prior chemotherapy (P2 < .0001). As compared with fungal abscesses, bacterial abscesses were larger (P2 < .00001) and fewer (P2 = .004). Antibiotics and percutaneous or surgical drainage effectively treated bacterial abscesses. Amphotericin B usually eradicated hepatic fungal infections.
  
  
  CONCLUSIONS
  The results of this study reveal the importance of the clinical setting in the diagnosis of hepatic abscesses in cancer patients. Aggressive treatment of these abscesses is indicated and is frequently effective.
