Hepatic resection for incidental liver tumors shows low mortality and acceptable morbidity. Malignant diseases, particularly hepatocellular carcinoma (HCC), are common, with better survival for incidental HCC cases.

Area of Science:

  • Hepatology
  • Surgical Oncology
  • Diagnostic Imaging

Background:

  • Incidental liver tumors (incidentalomas) are increasingly detected due to advances in imaging.
  • Limited data exists on the pathology and surgical outcomes of incidental liver tumors.
  • This study reviews a single-center experience with hepatic resection for incidentalomas.

Purpose of the Study:

  • To evaluate the pathology and operative outcomes of hepatic resection for incidental liver tumors.
  • To identify predictive factors for malignancy in incidental liver tumors.
  • To compare survival outcomes for incidental hepatocellular carcinoma (HCC) versus non-incidental HCC.

Main Methods:

  • Retrospective review of 1071 patients undergoing hepatic resection for liver tumors between 1989 and 2002.

  • Analysis of 107 asymptomatic patients with incidentalomas.
  • Histopathological examination of resected specimens and multivariate analysis of predictive factors.

    • Main Results:

    • Malignant tumors were found in 58% of incidentalomas, with HCC being the most common (48 cases).
    • Operative mortality was 1% and morbidity was 21%, with a median hospital stay of 8 days.
    • Incidental HCC patients had significantly better survival outcomes than non-incidental HCC patients.

    Conclusions:

    • Hepatic resection for incidental liver tumors is safe, with low mortality and acceptable morbidity.
    • Malignancy should be suspected in older males with large incidental hepatic lesions.
    • Early detection and resection of incidentalomas, especially HCC, can lead to favorable survival outcomes.
