Suprahyoid Hodgkin's disease stage IA

From 1973 to 1987, 71 patients (age greater than or equal to 16 years) with stage IA supradiaphragmatic Hodgkin's disease were treated with radiotherapy alone. 23 patients (20, clinical stage; 3, pathological stage) had disease localised to the suprahyoid region of the neck (upper deep cervical, 11; submandibular, 6; submandibular and upper deep cervical, 5; submental, 1). The age range was 17 to 64 (median 33). The male to female ratio was 2.8:1. The histological types were: lymphocyte predominant, 11; nodular sclerosis grade I, 8; mixed cellularity, 4. The 5 and 10 year cause-specific survival was 100% with a disease-free survival of 90% at 5 and 10 years. The proportion of patients with suprahyoid Hodgkin's disease IA was constant over the 15-year period. This only became apparent when the histology of patients with suprahyoid non-Hodgkin's lymphoma stage IA was reviewed.
