[Severe neurological toxicity (coma, convulsions, distal motor neuropathy) secondary to the association of accidental poisoning by isoniazid and a protocol containing high doses of vincristine].

Authors report the case of a 19 year old metastatic Ewing's sarcoma, prophylactically treated for suspected tuberculosis by Rifampicin and INH. Hepatic failure was induced by accidental overdose of INH. A high dose containing VCR protocol associated, lead to a coma with convulsions and severe motor peripheral neuropathy partially regressive. Neurological incidents of VCR, INH and their association are reviewed.

Burkitt-type lymphoma in France among non-Hodgkin malignant lymphomas in Caucasian children.

In a retrospective analysis of 87 cases of Caucasian childhood non-Hodgkin malignant lymphoma (NHML) from Lyon, France, all the case were diffuse lymphomas, but 47 were diagnosed as monomorphic small non-cleaved NHML, pathologically indistinguishable from Burkitt's lymphoma (BL). BL could then be the most frequent childhood lymphoma in France. This homogeneous series allows better definition of the characteristics of BL within NHML. Age distribution is similar to that of endemic BL, with a sex ratio of 3.7/1. Abdominal masses are initially present in 68% of the cases, whereas jaw is involved in only 4%. The disease is characterized by its overwhelming evolution in the absence of therapy. However, complete remission (CR) is usually obtained after the first chemtherapy regimen. Most relapses occur at 3-8 months. Death could be related to cerebrospinal fluid (CSF) involvement, local recurrence or secondary marrow involvement. Ninety per cent of the patients alive with no evidence of disease (NED) 8 months after CR can be considered as definitely cured. Our study on Caucasian children with NHML indicates that, from histological and clinical criteria, nearly half the cases are very similar to African BL. Even though EBV rarely associated with our cases, BL could be a worldwide lymphoma.

EBV-positive Burkitt's lymphoma from Algeria, with a three-way rearrangement involving chromosomes 2, 8 and 9.

Burkitt's lymphoma was diagnosed in male Algerian child presenting with abdominal and jaw tumours. Viral studies revealed that this non-endemic case was associated with the Epstein-Barr virus. Cytogenetic examination of tumour cells showed a complex three-way rearrangement involving chromosomes 2, 8 and 9. Our report indicates that, in Burkitt's lymphoma, not only simple but also complex translocation involving chromosome 8 may arise. This finding in a North African case emphasizes the need for more detailed study of the clinical, virological and cytogenetic features of Burkitt's lymphoma throughout the world.

Results of combined chemosurgical therapy for pulmonary metastases.

The authors study the results of the combined surgery and postoperative chemotherapy, for treatment of pulmonary metastases. At Léon-Bérard Center, 50 patients have been operated on since 1963. The sites and histologies of the primitive cancers are varied, corresponding to 12 epidermoid cancers, 12 adenocarcinomas, 10 osteogenic sarcomas, 1 Ewing's tumor, 3 malignant melanomas, 6 testicular tumors, and 4 others. The total survival rate is 30% in 4 years. The prognosis is influenced by different factors, which are studied. It depends on the histology of the primitive cancer and the type of the pulmonary excision. It is suggested that postoperative chemotherapy improves the results. It appears that the longer the free interval is between the treatment of the primitive cancer and the discovery of the pulmonary metastasis, the better the prognosis. The correlation between the time lapse of the free interval and the survey after pulmonary excision is studied. The conclusions of the authors are: The association of surgery and chemotherapy improves the results and enforces the indications for surgical excision of pulmonary metastases.

[Epstein-Barr virus associated Burkitt's lymphoma in a French child (author's transl)].

Pathologic diagnosis of malignant lymphoma, Burkitt type, was made in a 12 year old child with an abdominal tumour. The association of this lymphoma with Epstein-Barr virus was done based on the detection of Epstein-Barr viral markers within the tumour cells, as well as on the patient's serology. To our knowledge, it is the first time that the association between Burkitt's lymphoma and Epstein-Barr virus, which is frequent in Africa, is reported in a Caucasian French.

Initial management of advanced Burkitt lymphoma in children: is there still a place for surgery?

This retrospective study compared the overall survival, the event-free survival, and the timing of chemotherapy in patients with advanced Burkitt lymphoma with and without laparotomy. Thirty-five patients with advanced abdominal Burkitt lymphoma treated at least partially at the Centre Léon Bérard between 1981 and 1992 were included in this study. The diagnosis was obtained by laparotomy (LAP group) in 21 patients (17 stage III, 4 stage IV) and by other methods (non-LAP group) in 14 patients (5 stage III, 9 stage IV). The overall survival (71 and 93%) and the event-free survival (66 and 79%) were similar in the LAP and non-LAP groups, and the relapse rate was five (three local) in the LAP group compared with three (none local) in the non-LAP group. The local complication rate (9 of 21 versus 2 of 14) and the toxic death rate (2 of 21 versus 1 of 14) were slightly higher in the LAP group. Laparotomy also caused delays in therapy and increased the overall hospital stay. The mean interval from diagnosis to the start of the fourth course of chemotherapy was 57 days compared with 48 days and the average hospital stay was 44.4 days compared with 39 days for the LAP and non-LAP groups, respectively. Because advanced Burkitt lymphoma can be diagnosed by fine-needle aspiration, and chemotherapy cures more than 80% of the patients, there is no need for initial surgery, apart from acute emergencies. Furthermore, laparotomy delay chemotherapy and might reduce the survival rate.
