Lymphography for staging lymphomas: is it still a useful procedure?
OBJECTIVE
The purpose of this study was to determine the current value of lymphography in a series of previously untreated patients with Hodgkin's and non-Hodgkin's lymphoma seen at the M. D. Anderson Cancer Center over a 1-year period.


METHODS
From September 1989 through August 1990, 313 previously untreated patients with lymphoma were seen at our institution. In 221 of these, lymphography and CT were performed for abdominal staging. These studies were reviewed to determine if the examinations were complementary, or if the results of one or the other changed the staging in a significant number of patients. Staging was based on clinical findings, as laparotomies are rarely performed at this time.


RESULTS
Lymphograms were abnormal and CT scans were normal in two patients with Hodgkin's disease and in two with non-Hodgkin's lymphomas. Biopsy proof of nodal disease was not available for any of these, but the nodes did not change after therapy in three patients. The other patient was seropositive for HIV, and HIV disease itself can cause nodal abnormalities. In one patient with Hodgkin's disease and 12 with non-Hodgkin's lymphoma, lymphograms were normal and CT scans were abnormal, showing enlarged nodes and/or abnormal architecture. CT scans obtained after therapy showed regression of nodal and extranodal masses.


CONCLUSIONS
It was concluded that lymphographic findings did not significantly contribute to staging in these patients. This departure from previous experience may be due to improved state-of-the-art CT. In addition, the use of a combination of chemotherapy and radiation therapy to treat the lymphomas has increased, diminishing the need for detection of subtle nodal changes.
