[Radiotherapy of adult glial tumors: new developments and perspectives]. / Radiothérapie des tumeurs gliales de l'adulte : actualités et perspectives.

Adult gliomas (WHO grade II, III and IV) are heterogeneous primitive brain tumors. The prognosis of these tumors depends on multiple factors such as age at diagnosis, Karnofsky score, histopathology, biology and treatments. Radiotherapy (RT) plays an important role in the treatment strategy, after surgery. RT has been evaluated in terms of survival, median time to progression and toxicity. Techniques of RT have improved, during the last two decades: neuro-imaging (CT-scan, MRI and PET) and dedicated computers for dosimetry make it possible to deliver an homogeneous dose in the target volume while sparing normal tissues. Photons X are usually delivered with stereotactic or conformational noncoplanar techniques. Total doses delivered range from 50.4 to 60 Gy (1.8-2 Gy/fraction). Median survivals are different with regard to the tumor grade. However, genetic and biological factors also are important prognostic factors such as inactivation of the MGMT gene for glioblastomas and loss of heterozygosity (LOH) 1p/19q, usually associated with pure oligodendroglioma. During the 1990s, temozolomide (TMZ) was specifically developed as a chemotherapy agent against primary brain tumors. The current TMZ/RT regimen in newly diagnosed GBM has been proposed as a standard treatment. The optimal treatment strategy is not known. New clinical trials are needed to assess new techniques of RT; a further improvement in medical treatment requires novel agents.

[Bevacizumab/irinotecan. An active treatment for recurrent high grade gliomas: preliminary results of an ANOCEF Multicenter Study]. / Bevacizumab/irinotecan. Un nouveau traitement actif dans les gliomes de haut grade récidivants: résultats préliminaires d'une étude multicentrique de l'Anocef.

RATIONALE: Second-line chemotherapy is disappointing in recurrent high-grade gliomas. Dramatic responses in recurrent high-grade gliomas have been reported in a recent monocentric trial with a novel association combining bevacizumab (anti-VEGF monoclonal antibody agent) and irinitecan. OBJECTIVE: To report the experience of the ANOCEF group (French speaking neuro-oncology association) using the bevacizumab-irinotecan combination in recurrent high-grade gliomas. METHODS: Eight centers were involved in this retrospective multicenter study. Bevacizumab-irinotecan was delivered as previously described in a compassional setting to non-selected patients suffering from a high-grade glioma (WHO grade III and IV). Response rate at two months of the onset of the treatment was analyzed using the Macdonald criteria. The toxicity profile of the treatment was also investigated. RESULTS: From 2006 to 2007, 77 patients were treated (median age: 52 years; median Karnofsky score: 70) for a recurrent high-grade glioma (49 grade IV, 28 grade III). At two months, the response rates were objective response=36% (54% in grade III and 27% in grade IV); stable disease=39%; progressive disease=13%; patients not evaluable because of a rapid fatal clinical deterioration=12%. Improvement was noted in 49% of patients. Among the main toxicities, we noted; intratumoral hemorrage (n=5 with spontaneous regression in three) and thromboembolic complications including venous thrombophlebitis (n=4), pulmonary embolism (n=2), myocardial infarction (n=1), grade III-IV hematotoxicity (n=2), reversible leukoencephalopathy (n=1). CONCLUSION: This retrospective multicenter study adds further arguments in favor of the promising results of this new combination and its potential rapidity of action in recurrent high-grade gliomas. Antiangiogenic agents expose the patients to a well-known risk of thromboembolic and hemorragic complications, necessitating careful follow-up and patient selection in light of the cardiovascular contraindications.

[Combination of etoposide, cisplatin and ifosfamide (VPH) in the salvage chemotherapy of relapsing or refractory aggressive malignant lymphoma. Study of 51 patients]. / Association d'étoposide, de cisplatine et d'ifosfamide (VPH) dans la chimiothérapie de "rattrapage" des lymphomes malins agressifs en progression ou en rechute. Etude sur 51 patients.

Fifty-one patients with non-Hodgkin's lymphoma refractory or relapsing after CHOP-like regimen, underwent a salvage chemotherapy by VPH: etoposide 100 mg/m2/d, D1 to D3, cisplatin 20 mg/m2/d, D1 to D5, ifosfamide 1 g/m2/d D1 to D5, mesna 1.2 g/m2/d D1 to D5, every 4 weeks. Among 46 evaluable patients for efficacy, 21 (45.6%) achieved complete or partial response according to WHO criteria and 25 (54.3%) failed, while five cases (9.8% of all patients) were not evaluable (two initial complete remission before VPH, two early toxic deaths and one confusional syndrome). Thirty-five patients (68.6%) died of lymphoma, three (5.8%) of acute toxicity and 13 (25.5%) are alive: five in complete remission. The toxicity is mainly myelo-suppression, digestive and renal but could be managed as usually. Although the follow-up is short, this regimen appears effective in these circumstances after CHOP failure but it should be used early, before overt chemoresistance. It does not hinder a bone marrow transplantation programme.

[Internal medicine DES 10 years after creation. Results of the survey realized by the Association of young internists]. / Le DES de médecine interne 10 ans après sa création. Résultats de l'enquêt réalisée par l'Association des jeunes internistes.

The internal medicine young practitioners association (AJI) did set, during 93 spring, a survey among the registered internal medicine interns since 1984, regarding their training and future. 88 did answer, showing a certain homegeneous training but a deep care in their future. Most would wish a dual activity in general hospitals : internal medicine and an other speciality acquired during their training.
