Abstract

Since 1975, nine children with testicular leukemia were treated at the University of Kansas Medical Center on a standard protocol. Six patients presented with overt testicular leukemia and three patients had microscopic testicular leukemia detected on a biopsy done after 3 years of continuous complete remission. All patients had an M1 bone marrow at the time of testicular relapse and one patient had a concomitant central nervous system (CNS) relapse. Therapy consisted of testicular irradiation, CNS chemoprophylaxis, and systemic reinduction chemotherapy. Systemic maintenance therapy after the testicular relapse consisted of 6‐mercaptopurine and methotrexate with vincristine/prednisone pulses adminsitered in the same basic dose and schedule as the patienťs original maintenance regimen. These nine patients had a mean duration of first remission of 33 months and a mean duration of second remission of 45+ months. Four patients have relapsed (two bone marrow, one CNS, one CNS + bone marrow), but five patients remain in their second complete remission for 33+ to 94+ months from the time of testicular relapse. These results demonstrate that, in some children, testicular leukemia represents a site of temporary drug resistance and long‐term second remissions can be obtained (once local disease is controlled) by using the initial maintenance chemotherapy regimen.
