Leukemic infiltration of the testis during long-term remission.
Of 33 boys with acute lymphocytic leukemia treated at the Cincinnati Children's Hospital during 1971--1974, 14 remained in clinical and bone marrow remission for periods longer than 2.5 yr. Of these 14 patients, 8 then developed testicular leukemia. In 7 of these 8 patients, testicular infiltration was the first or only evidence of relapse. In 2 of the patients the gonads were not grossly abnormal, and testicular relapse was discovered as a result of routine wedge biopsy before therapy was to have been stopped. This experience has led to our policy of routine testicular biopsy in boys with acute lymphocytic leukemia who have had continuous remission for 3 yr and who are otherwise candidates for discontinuance of maintenance therapy.
