[Recurrences of lymphosarcoma of the pharyngeal ring after radiotherapy].

To study the frequency and nature of recurrences of lymphosarcoma of the throat ring, the course of the disease was analysed in 49 patients with a complete remission after radiation therapy. A clear-cut effect of a primary tumor site on recurrence development time was shown. Recurrences develop faster in primary rhinopharyngeal affection than in tonsillar affection. The dissemination of a tumor process involved both the lymph nodes and extranodal zones. Frequent involvement of the stomach was noted in particular.
