Fourteen files of patients having had Hodgkin's disease have been analyzed retrospectively to assess the justification of systematic surveillance after complete remission has been achieved. The data of successive CT exams, compared with the findings of clinical and biological studies performed on the same dates, confirm the primordial role of imaging, since computed tomography was predictive for 7 of 18 events (14 relapses and 4 second progressions). The occurrence of subphrenic recurrence in 3 cases for which the initial site was mediastinal leads to discussing the merits of a yearly thoraco-abdomino-pelvic examination during the two years following complete remission.
