The incidence and frequency of CNS relapses in long term surviving adults, age eighteen and over, covering the period 1967–1972, were presented. Four of 20 patients with ANLL and 12 of 24 patients with ALL were demonstrated to have CNS leukemia during the course of their illness. The onset of neurologic manifestation in three of four ANLL patients with CNS leukemia was observed within three months of the diagnosis, whereas it was delayed to 6–12 months interval in eight of 12 ALL patients. CNS relapses, a major determinant for CNS prophylactic and maintenance therapy, were observed in 75% of the patients with ALL and none in ANLL patients who were treated with I.T. chemotherapy and cranial radiation of 2000 R. Therefore, our observation suggests that CNS prophylactic and maintenance therapy should be of value in adults with ALL as in children; whereas, in ANLL, further observation is warranted before any definite therapy can be advocated.
