Long term outcome in adolescents with Hodgkin's lymphoma: poor results using regimens designed for adults.
It is unclear whether the outcome in adolescents with Hodgkin's lymphoma is as good as that in children and there are no prospective randomized trials comparing regimes used in children and adults in this setting. We have therefore performed an analysis of 210 adolescent patients diagnosed with Hodgkin's lymphoma between 1970-1997 and registered on the database held by the British National Lymphoma Investigation. Patients were treated according to adult regimens current at the time of their diagnosis. The complete response rate recorded in 209 patients was 76%. This was highly dependent on disease stage being 95% in patients with localized disease but 63% in those with advanced disease. The 5 year event free survival for the whole cohort was 50% falling to 41% at 20 years with overall survival of 81% falling to 68% at 5 and 20 years respectively. There is no significant difference in the 3 decades pertaining to this analysis. Of the 62 deaths in this cohort, 70% were due to Hodgkin's lymphoma but of the 13 deaths occurring beyond 10 years, only 3 were due to Hodgkin's lymphoma, the reminder being attributable to the late effects of therapy. Results from paediatric groups have been much more encouraging than those presented from this cohort. It seems the use of risk-adjusted combined modality therapy with minimization of radiation fields and doses and reduction of anthracycline and alkylator exposure has been successful in children and should be used in adolescents.
