title: Testicular disease in childhood B-cell non-Hodgkin's lymphoma: the French Society of Pediatric Oncology experience.
abstract: OBJECTIVE
  To investigate whether testicular disease in childhood B-cell lymphoma should continue to be considered a sanctuary site, as it is with other lymphoid malignancies such as acute lymphoblastic leukemia.
  
  
  METHODS
  Seven hundred forty-two children with B-cell non-Hodgkin's lymphoma were included in the LMB protocols of the French Society of Pediatric Oncology from February 1981 to May 1994. Thirty patients (5.3%) had testicular involvement at diagnosis. We describe the clinical presentation and outcome of these 30 patients, who were treated without local radiation therapy.
  
  
  RESULTS
  Five patients underwent diagnostic orchidectomy. The median patient age was 8.5 years (range, 2 to 14 years), and their cancers were stage III (18 patients), stage IV (five patients), and B-cell acute lymphoblastic leukemia (seven patients). Five patients had central nervous system involvement. Twenty-eight patients (95%) achieved complete remission. Twenty-six patients are alive without progressive disease (median follow-up, 6.5 years).
  
  
  CONCLUSIONS
  Testicular disease does not seem to confer a poor prognosis, and it is curable with intensive combination chemotherapy alone. Local treatment (surgery or radiation) is avoidable; therefore, gonadal function can be preserved.
