We report a 15-year-old boy diagnosed with acute lymphoblastic leukemia (ALL) in 1983. Induction therapy included L-asparaginase. After the second dose of L-asparaginase, he had a left sided focal seizure and computed tomography (CT) scan of the head showed a right frontal infarct. No further L-asparaginase was given. Complete remission was achieved and he successfully completed therapy in 1986. Eight months later he had an isolated bone marrow relapse. Reinduction therapy included L-asparaginase. After the fourth dose of L-asparaginase, he presented with severe headache and a CT scan showed a right temporal infarct. Repeat infarction on rechallenge with L-asparaginase has not been previously reported. Prophylactic therapy, such as fresh frozen plasma, should be considered before patients, with a previous cerebral insult, are rechallenged with L-asparaginase. However the effectiveness of such therapy has not been established.

We report the first known case of daunorubicin administered directly into the human central nervous system. A 3 1/2-year-old female with pneumonia and otitis media was diagnosed with acute lymphoblastic leukemia and was admitted for antibiotics and chemotherapy. On the first day she inadvertently received a 17 mg intrathecal (IT) injection of daunorubicin. When the error was recognized about 1 hour later, her cerebrospinal fluid (CSF) was exchanged with sterile saline by barbotage, IT hydrocortisone was given, a subarachnoid catheter was inserted, and the CSF was allowed to drain for 36 hours. Only 5.6 mg (33%) of the dose was recovered from CSF, 2.7 mg as daunorubicin and 2.9 mg as the metabolite, daunorubicinol. Initially she was asymptomatic and induction therapy continued with vincristine, 1-asparaginase, prednisone, and IT methotrexate. One week after the daunorubicin injection she developed headache and irritability; CSF protein was 3.2 gm/dl. On the 12th day, she developed fungal sepsis and worsening pneumonia. On the 15th day, she became comatose with a flacid paraparesis, areflexia, and an ascending progressive bulbar palsy. A series of computerized tomography scans over 6 weeks showed increasing diffuse cerebral atrophy. Nerve conduction velocity studies were consistent with an axonal neuropathy. Despite her multiple concurrent medical problems, the timing and characteristics of neurologic damage suggest that IT daunorubicin caused progressive destruction of the nervous system.

The case histories of two patients with acute lymphocytic leukemia, who developed central nervous system complication during combined chemotherapy are described. The neurological picture could be characterized by symptoms of headache, mental deterioration, hemiparesis and seizures. Following L-asparaginase administration one patient had intracranial thrombosis with focal seizures and hemiparesis associated with clotting abnormalities, including severe hypofibrinogenemia and decreased antithrombin III activity. In the other patient, it was after intrathecal administration of Methotrexate when mental deterioration associated with the symptoms of progressive leukoencephalopathy occurred. It arises the possibility that with increasing complexity of combined chemotherapy the occurrence rate of neurological complications will also increase.

A 16-year-old male with acute myelogenous leukemia (M1) presented with fulminant hepatitis (massive hepatic necrosis). He achieved a complete remission with the administration of AdVP (doxorubicin, vincristine and prednisolone), and thereafter received consolidation or intensification therapy 5 times in combination with AdVP plus enocitabine. A bone marrow examination carried out before the 6th round of chemotherapy revealed a slight increase of myeloblast (7%). L-AdVP (including l-asparaginase in addition to AdVP) was administered with a good result. However, 13 days after the end of the therapy he complained of acute abdominal pain, headache and fever. The following day, his consciousness level became lower and severe jaundice appeared. The serum transaminase level highly elevated with PT and aPTT severely elongated. He was diagnosed as having fulminant hepatitis. Elevation of the titer of IgM-HBc suggested that the fulminant hepatitis was attributed to HBV, which was probably transmitted by blood transfusion done in the first induction therapy and stayed latent during immunosuppressive chemotherapy. After receiving 10 sessions of plasma exchange (3.2 l/day), he recovered, free from any major complications except posttransfusion hepatitis. In his serum taken at 1 month after the recovery of posttransfusion hepatitis, HCV (Chiron) antibody was detected. There have been few reports concerning fulminant hepatitis associated with acute leukemia. In this case, plasma exchange was very effective in treating fulminant hepatitis.

A 13-year-old girl with preB-ALL was admitted because of headache during maintenance therapy including L-asparaginase. Magnetic resonance imaging revealed cerebral thrombosis. Coagulation studies showed decreased levels of fibrinogen, antithrombin-III and plasminogen. The patient was treated with antithrombin-III concentrates and fresh frozen plasma and recovered quickly. These findings suggest that coagulopathy induced by L-asparaginase is associated with the pathogenesis of cerebral thrombosis.

Malignant lymphoma of the central nervous system in a thirteen-year-old boy with immotile cilia syndrome (ICS) is reported. He had frequent upper respiratory tract infections, chronic sinusitis and pneumonia during in childhood. Bronchiectasis was demonstrated by bronchography. The diagnosis of ICS was confirmed by the lack of dynein arms of cila in the nasal mucosa with electronmicroscopy. In 1987, he complained of headache and vomiting and a space occupied mass lesion in the left frontoparietal lobe was found by head CT scan, which was subtotally resected. Histological studies showed large cell type non-Hodgikin lymphoma of B-cell phenotype. He received radiotherapy (41Gy) to the whole brain and systemic chemotherapy consisting of adriamycin, cyclophosphamide, vincristine, prednisolone, L-asparaginase and intrathecal methotrexate, and the patient maintained complete remission for eight months. However, relapse occurred and the patient died twelve months after the initiation of treatment.

Sudden cerebrovascular insults occurred during or immediately following remission induction therapy in 4 children with acute lymphoblastic leukemia. In 3, cerebral infarction was due to thrombosis. In the fourth, an intracerebral hematoma developed representing either frank hemorrhaging or a hemorrhagic infarction. None of the patients had central nervous system leukemia or extreme leukocytosis at the time of diagnosis. Symptoms were obtundation, hemiparesis, seizures, and headache. The induction chemotherapy included L-asparaginase which causes deficiencies of antithrombin, plasminogen, fibrinogen, and factors IX and XI. These hemostatic abnormalities may explain the thromboses and bleeding observed in these children.

Dural sinus thrombosis developed in two children with acute lymphoblastic leukemia during induction treatment with vincristine sulfate, prednisone, and asparaginase. Headache, nausea, emesis, and lethargy were the presenting signs. The diagnosis was confirmed by arteriography. The cause is presumed to be secondary to hypercoagulability due to asparaginase-induced antithrombin III deficiency. The patients received anticoagulation therapy and recovered completely. Only two of the six reported patients without heparinization survived.

L-Asparaginase therapy for childhood acute lymphoblastic leukemia causes deficiencies of plasma hemostatic proteins, especially antithrombin, plasminogen, and fibrinogen. Severe thromboses and hemorrhages occurred in 18 children receiving vincristine, prednisone, and asparaginase therapy for ALL. Thirteen children had intracranial thrombosis or hemorrhage, four had extremity thrombosis, and one had both an intracranial hemorrhage and an extremity thrombosis. These events occur characteristically in the third and fourth weeks of therapy during or just after a three-week course of L-asparaginase. Symptoms of headache, obtundation, hemiparesis, and seizure were common for the intracranial events: local pain, swelling, and discoloration were common for the extremity thromboses. These complications have been recognized in 1 to 2% of children undergoing induction therapy which includes asparaginase.

Dural sinus thrombosis (DST) has been reported in association with cancer in both adults and children. We describe the seven patients seen with this complication in our centre between 1981 and 1995. Diagnosis was confirmed by either cerebral CT scanning, MRI or angiography. Median age was 13 years (range 8-15). Six patients were boys. Six children were being treated for non-Hodgkin lymphoma and one for neuroblastoma. Presenting symptoms were seizures and transient neurologic deficit, often preceded by headaches. The probable cause of DST was found in two cases. Tumour localisation in the central nervous system (CNS) probably caused DST in one patient who was treated for ki 1 lymphoma. Dehydration in combination with a poor general condition seemed to be the cause of DST in the patient with neuroblastoma. In five children with stage III or IV non-Hodgkin lymphoma (three lymphoblastic lymphoma; two Burkitt's lymphoma), etiology remained unknown. In these children, DST occurred early in the course of therapy. The median interval between start of chemotherapy and onset of symptoms was 19 days (range 8-40). No child had received L-asparaginase. Prognosis was favourable, with symptoms completely disappearing without therapy within 1 to 5 days. The incidence of DST in patients with advanced stage non-Hodgkin lymphoma during induction and consolidation was calculated to be below 3%. We conclude that DST is rarely diagnosed in children with cancer. Occurrence during the initial phase of therapy for non-Hodgkin lymphoma is associated with a benign prognosis.
