[Hodgkin's disease under twenty years of age--clinicopathological study].
Twenty two cases with Hodgkin's disease under 20 years of age who were diagnosed and treated in National Cancer Center during 1962-1986 were studied retrospectively. The most common initial symptom was swelling of lymph nodes (86%) and only 5 cases (23%) showed "B" symptoms. Laboratory findings showed that there were some cases with increased WBC counts but only 2 cases with an elevated LDH value. In 2 out of 4 cases serum copper value correlated well with their clinical state. Histologically lymphocyte predominance type, mixed cellularity type and nodular sclerosis type almost equally occurred in children younger than age 15 years. On the other hand nodular sclerosis type with mediastinal mass was predominantly encountered in older patients (especially female). The ten years' survival rate in stage I and II patients was 59% compared with 21% in stage III and IV patients. As for the results of initial treatment, complete remission and 10 years' survival rate were 91% and 87% in recent 12 years (1975-1986) compared with 55% and 36% in the preceding 13 years (1962-1974) respectively. Autopsy findings revealed rare involvements of the central nervous system and kidneys. Various late effects which may be caused by escalating doses of radiotherapy occurred in 6 out of 9 cases under the age of 15 years who survived. On the basis of these results lower-doses of radiotherapy combined with systemic chemotherapy appeared to be advisable for the treatment of childhood Hodgkin's disease.
