[en] The analysis was realized at 134 patient's of median age 61 years. It was in 65 % of cases a epidermoid carcinoma and 35 % of an adenocarcinoma, undifferentiated in 9% of cases and well differentiated in 29 % of the cases. The majority of tumors were of stage 3 (79 %). The Tep has led a new dosimetry for 21.6 % of the inclusive. In the end the decision of radiotherapy was cancelled for 9 patients (6.7 %). At 43 patients (34 %), the Tep has led a modification of the radiotherapy protocol. These modifications concerned the total dose ( 20 patients), the dose by session ( 5 patients), the total volume ( 34 patients), the number of beams ( 11 patients) or the number of volumes ( 10 patients).

[en] As 200.000 patients including 700 children are treated by irradiation every year in France, and as more than 5 per cent are exposed to non-predictable after-effects, the authors report the development of a diagnosis test for adults based on the in-vitro estimation of the functional repair and signalling of DNA double strand breaks. By using indirect immunofluorescence, they demonstrate a quantitative correlation between cellular quantitative sensitivity and the rates of non-repaired DNA double strand beaks. This approach, called Preditox, has been validated on 80 patients and presents the required characteristics to be a screening test of radio-sensitive patients. Short communication

[en] Two articles in hematology, myeloma or Khaler disease for the first one, the objective of the study was to precise the epidemiological, clinical characteristics and the therapy modalities of this disease from a retrospective study. The second article treats the real impact of the PET scanography with 18-FDG on the decision and modalities of radiotherapy in the Hodgkin disease. (N.C.)
