Description détaillée
The nuclear and radiologic risks monitoring is a major preoccupation for our society. During an accident, it is primordial to define the biologic dosimetry. The dose and distribution knowledge is crucial for the medical care. Indeed, Total Body Irradiation (TBI) and Partial Body Irradiation (PBI) do not have the same clinical outcome. A Total Body Irradiation induces an acute radiation syndrome with a Medullary Aplasia. A quick diagnostic would allow the optimization of the medical care.
Nowadays, the analyse of the chromosome with two centromeres is the current norm to estimate the radiation dose, but this technique is time consuming, and not adapted to an emergency situation, and to a large population.
The new genetic techniques could permit the quick radiation dosimetry diagnosis. The research of early exposition bio-markers seems to be of a major interest. These bio-markers would allow to rapidly define the radiations perceived by an exposed subject, before the apparition of the symptoms, and by the way, to conduct to a therapeutic strategy more adapted to the patient.
In this purpose, the present study will need blood and urines samples of patients totally or partially exposed to radiations, according to their usual medical care.

|---|---|
|
Expérimental: Total Body Irradiation
Patient suffering from a malignant blood disease that requires a total body radiation, without (or prior to) a concomitant chemotherapy, according to the following protocol: 2x2 Gray per day, for 3 days.
Blood and urines samples will be performed at days 0, 1, 2 and 3 of the treatment plan.
|
For all patients the blood samples must be organized: Before, 4 hours (+/-30 min), 1 day, 2 days, and 3 days after the start of the radiation therapy. Collections of urine must be organized: Before, 1 day, and 2 days after the radiation therapy. |
|
Expérimental: Partial Body Irradiation
Patient with at least one bone metastasis localized at the pelvis and requiring partial body radiation therapy without associated chemotherapy, according to the following protocol: 4 Gray per day for 5 days will perform blood and urines samples at days 0, 1, 2 and 3 after the beginning of the radiation treatment.
|
For all patients the blood samples must be organized: Before, 4 hours (+/-30 min), 1 day, 2 days, and 3 days after the start of the radiation therapy. Collections of urine must be organized: Before, 1 day, and 2 days after the radiation therapy. |
