THE SURVEY: To better ascertain diagnostic and treatment strategies used by physicians for idiopathic thrombocytopenic purpura, a questionnaire was addressed to 298 French hematologists and pediatricians. One hundred and ten responses were analyzed. DIAGNOSTIC APPROACH: Thrombocytopenia was determined on capillary blood samples by 50% of the physicians and platelet-associated antibody by 44%. Bone marrow aspirates were obtained more frequently in adults (85%) than in children (47%) and immune disorders were more often investigated in 95% of adults and in 68% of children. THERAPEUTICS: Treatment threshold was lower in children (20.10(9)/l) than in adults (50.10(9)/l). Corticoidsteroids was the treatment of choice in adults (98%) and children received either IV immunoglobulins (61%) and/or corticosteroids (63%); higher doses were used in children (> or = 2 mg/kg versus 1 mg/kg) for shorter periods (> or = 2 weeks versus > 3 weeks). Treatment failure was evaluated earlier in children (< 10 days) than in adults (> 20 days). RECOMMENDATIONS: 1. Diagnosis. Based on repeatedly low platelet counts and verification that only platelets are involved. Clinical examination is normal excepting rare cases of severe hemorrhage. Search for antiplatelet antibodies is non-contributive 2. Treatment Short-term corticosteroids, both in children and adults. Intravenous gammaglobulins should be limited to cases with signs of severe hemorrhage. 3. Consult the complete guidelines for each individual clinical situation.

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.
