Continued complete remission without systemic therapy for isolated testicular relapse after bone marrow...

ITR after BMT in cases of acute lymphoblastic leukemia is relatively rare. Treatment for ITR after BMT generally consists of a combination of local irradiation, orchiectomy, and systemic chemotherapy. However, the effectiveness of these modalities has not been established. Both irradiation and systemic chemotherapy including a second transplantation would result in additional toxicity. In this report we describe a boy with ITR 91 months after BMT who has remained in complete remission more than two yr after a unilateral orchiectomy. We did not treat this patient with systemic chemotherapy, as his ITR developed very late. Our experience suggests that orchiectomy alone is a reasonable option for very late ITR after BMT.
