Clinical analysis of 18 cases of adult patients with acute lymphocytic leukaemia grouped by immunologic subtyping

18 cases of adult patients with acute Lymphocytic leuaemia （ALL） were classified by theuse of monoclonal antibodies,among whom 13 were defined as common ALL;4 as Null ALL,and1 as T ALL.The mean duration of first complete remission （CR）attained was 39.4 dags in morethan half of the C-ALL,and while in CR sustained for 12.5 months.8 of the 13 C-ALL casesdied with a mean survival of 20.4 months.None of the 3 treated N-ALL patients attained CR,2of whom died with a survival of 1.8 and 11 months respectively.1 case of T-ALL survived for 1month.The results suggest that the immunologic subtying in adult ALL seems of value in evalu-ating the response to therapy and prognosis.
