[Homonymous lateral hemianopsia revealing cerebral thrombophlebitis. Role of a deficiency of protein S induced by l-asparaginase].

BACKGROUND: Cerebral thrombosis associated with protein S deficiency is very rare and is mainly related to hereditary form of protein S deficiency. CASE REPORT: A 19-year-old girl with acute lymphoblastic leukemia presented hemianopsy within a few days after the first administration of L-asparaginase. Magnetic resonance of the brain showed a cortical infarct. A marked decrease of the level of protein S was documented. Few days later, the patient was free of symptoms and protein S level was restored to the normal suggesting that the cerebral thrombosis was caused by transient protein S deficiency induced by L-asparaginase administration. DISCUSSION: Patients with neurological complication caused by L-asparaginase should be tested for protein S and other anticoagulant deficiencies.

Intensive treatment of stage III-IV aggressive malignant lymphomas (protocol TPL-84).

BACKGROUND: Much progress has been made in the last ten years in the treatment of non Hodgkin's lymphomas by increasing drug schedules and by using non cross-resistant regimens. METHODS: So we decided in 1984 to test a new multiple drug protocol (Tours-Poitiers-Limoges = TPL protocol) which used a sequence of three courses of classical high-dose induction therapy, three courses of consolidation therapy using Teniposide, Cytosine Arabinoside, L Asparaginase and high-dose Methotrexate, and three courses of late intensification using the same drugs as induction therapy. Results. Thirty-eight patients younger than 60 years were included. Complete remission was obtained in 27 patients (71%). The median follow-up was 3 years and 9 months with one third of CR patients having been followed beyond 5 years. Seven patients relapsed (26% of CR patients) and one died of toxicity in complete remission. At present 22 patients (58%) are in complete remission, 19 in first CR, 1 in first CR after allogenic bone marrow transplantation, and 2 in second prolonged CR after autologous bone marrow transplantation. The median survival time is 48 months and the actuarial disease-free survival curve seems to have a plateau at 48.5%, with no relapse after 24 months. CONCLUSIONS: These results confirm the efficacy of alternating high-dose conventional chemotherapy in the treatment of intermediate and high-grade NHL, with about half of the patients being cured. However, more intensive chemotherapy regimens are needed to improve cure rates.

[First-line treatment of severe myelomas of the young subject by high-dose melphalan].

Six patients (aged 39 to 55 years) with stage III myelomas were treated with IV high dose melphalan (HDM) 140 mg/m2. They had previously received only one or two courses of conventional chemotherapy. The extrahematological tolerance of the procedure was good. The duration of neutropenias (less than 500/mm3) was 14 to 24 days. Complete remission (CR) was obtained in 4 cases but one patient died in CR of invasive aspergillosis. In the other 3 cases, bone marrow was cryopreserved without ex vivo treatment and reinfused after a 2nd course of HDM. These patients remain in apparent CR 12, 20 and 34 months after the diagnosis although one of them had a pure meningeal relapse treated with a second autograft. These results suggest that CR can be obtained with HDM but at the expense of profound myelosuppression. Long term disease control can be obtained but the role of the 2nd course of HDM with autologous bone marrow transplantation warrants further study.
