A case of malignant lymphoma in a patient with high levels of CA125 and CA19-9

The authors encountered a case of malignant lymphoma in a patient who had h igh levels of CA125 and CA19-9. These tumor markers showed almost identical changes during the clinical course of the disease. To date, there has been no investigation of these markers as they relate to malignant lymphoma. Un fortunately, the normal values of CA125 and CA19-9 in children were not kno wn and thus this case could not be compared with disease-free children. Thi s study shows CA125 and CA19-9 levels of the children that do not have the malignant diseases, and reports on one case of malignant lymphoma in a pati ent who presented with high levels of these markers.
