Monitoring the response of lymphoma patients to therapy: correlation of abdominal CT findings with clinical course and histologic cell type

TW Oliver Jr, ME Bernardino and PJ Sones Jr

A review was made of 365 abdominal computed tomographic (CT) examinations in 125 patients with a histologic diagnosis of lymphoma who had undergone CT before and after therapy. Clinical correlation immediately preceding the follow-up CT examination was obtained in 100 patients. In these 100 patients, five distinct subgroups emerged: (a) reduction in extent of disease without changes in internal nodal characteristics; (b) reduction in extent of disease with change in internal nodal characteristics; (c) no change in extent of disease and no change in internal nodal characteristics; (d) no change in extent of disease but change in internal nodal characteristics; and (e) disease progression. Changes in internal nodal architecture consisted of diminished attenuation or mesenteric "stranding." A 91% correlation existed between the CT findings and the clinical course. Of those patients with a worsening clinical course, and follow-up CT studies suggesting a stable or improved response to therapy, relapse in the majority (57%) involved the central nervous system. The authors conclude that limited abdominal CT examination is satisfactory in the posttherapy follow-up of lymphoma patients.
