Computed tomography (CT) in the staging of patients with Hodgkin's Disease: a report on 136 patients.

One hundred and thirty-six patients with biopsy proven Hodgkin's disease (HD) had conventional staging investigations and CT carried out at presentation. CT did not detect 20 out of 24 positive spleens and did not detect disease at 16 involved lymph node sites proven at laparotomy. In 60 cases in whom lymphography was performed, CT detected all disease shown by lymphography and showed additional disease in 13 other cases (three within the lymphogram area). In 43 patients CT was the only investigation of the abdomen that could be performed and identified 31 unexpected areas of disease in this group. CT altered the stage of the patients in 16% of cases compared with 8% (lymphography) and 34% (laparotomy). The importance of CT as a baseline investigation for the subsequent monitoring of the complete remission of all known disease is discussed, and the routine use of CT when available as the primary non-invasive staging investigation of the abdomen in HD is recommended.
