Between January 1978 and September 1979, 29 children with acute leukemia in complete continuous remission for three or more years were examined for evidence of occult extramedullary disease immediately prior to discontinuation of chemotherapy. Bilateral open wedge testicular biopsy demonstrated the presence of bilateral leukemic infiltrates in 2/13 boys. Gallium scans prior to biopsy had identified unilateral infiltration in an enlarged testis in one patient but failed to identify microscopic disease in the opposite testis or in the testes of the second patient. Percutaneous kidney and liver biopsies, pelvic ultrasonography, intravenous pyelogram, skeletal survey, cranial computed axial tomography scan, electroencephalography, and ophthalmologic examinations failed to demonstrate evidence of occult disease. Except for testicular biopsy, this study does not support extensive clinical or invasive procedures to identify extramedullary disease prior to discontinuation of chemotherapy.
