This prospective study assesses the contribution of lymphography (LAG), abdominal-pelvic computed tomography (CT), and bone marrow biopsy to the staging and management of 168 consecutive cases of newly diagnosed non-Hodgkin lymphoma (NHL). LAG and/or CT influenced Ann Arbor clinical stage (CS) in 39 patients (23%) and Ann Arbor pathologic stage (PS) in 23 patients (14%) by detection of clinically inapparent retroperitoneal adenopathy and/or extranodal disease. LAG findings raised the CS in eight patients and the PS in six of the eight by showing adenopathy when the CT results were negative. By depicting extranodal disease, CT resulted in the CS being raised in an additional ten patients and the PS in six of the ten. Of the diagnostic tests assessed, bone marrow biopsy and/or cytology had the greatest influence on staging. Clinical staging that included LAG/CT resulted in the identification of only 30 patients with CS IV disease, whereas an additional 53 CS I through CS III patients had their disease stage raised to PS IV due to positive bone marrow biopsy/cytology results. However, 42 of the 53 patients already had advanced (CS III) disease. Initial case management was influenced by LAG, CT, or bone marrow biopsy/cytology results in 27 of 168 patients. LAG/CT results influenced management in 20 of 27 cases, while bone marrow biopsy/cytology results caused initial management changes in only seven of the 27 cases.
