Acute leukemia: diagnosis and management of testicular involvement.
Contemporary therapy of acute leukemia frequently achieves long-term continued complete remission (CCR) of bone marrow disease and prevents central nervous system relapse. However, accompanying improved survival is an increasing incidence of overt testicular relapse either during CCR or associated with bone marrow relapse. In 7 boys testicular abnormalities developed during CCR, 6 had open biopsy and 5 had histologically confirmed leukemic infiltration. Despite local therapy of orchiectomy or irradiation and chemotherapy reinduction, 2 of 6 had testicular relapse and 4 of 6 died. Three boys with coexistent overt testicular and systemic relapse died. Nine boys with normal testes had testicular biopsy during CCR prior to discontinuation of chemotherapy. Results of all biopsies were benign, but one boy had a relapse. The diagnosis of occult testicular leukemia prior to discontinuation of chemotherapy allows selection of high-risk boys requiring prolonged, intensive, and possibly alternative therapy. The indication for testicular biopsy in boys with acute leukemia is documented, and appropriate clinical management of testicular leukemia is presented.
