Surgical restaging of Hodgkin's disease.

Twenty-six patients with Hodgkin's disease were restaged both clinically and surgically within 2 months of completing their planned chemotherapy. Six patients (23%) had surgically proven persisting disease. Patients were divided into three groups: group I--eight patients had normal findings at clinical restaging and all were free of disease at surgery; group 2--13 patients had abnormal findings at clinical restaging, but only two (15%) were surgically documented to have persistent disease; and group 3--five patients had incomplete clinical restaging but, because of initial bulky disease, underwent surgical restaging, which showed that four patients had residual disease. The spleen was the site of persisting disease in all six patients with residual disease; four also had para-aortic nodal involvement. All 20 patients in pathologically documented complete remission remain relapse-free, with a mean followup of 26 months. This is significantly better (P less than 0.001) than the 21% relapse rate for 224 comparable patients in complete remission established by clinical but not surgical restaging. It appears that surgical restaging provides useful prognostic and therapeutic information in selected patients with Hodgkin's disease.
