The oncologist includes patients responding to criteria and not opposing the collection of their data. He submits a request for whole-body MRI and PET-CT to the Medical Imaging and Nuclear Medicine departments of the Oscar Lambret Centre. If the patient has benefited within the previous 15 days of any of these examinations, it is not performed again : it will serve as an initial examination. Following these examinations, the oncologist completes the reading grid. A clinical examination and a questioning with the main stages of the disease is performed and data are reported in the dedicated sheet. A prescription of tumor markers and of bone remodeling is performed (in the absence of recent results), and the results are reported on the same sheet.
After 3 cycles (of intravenous chemotherapy) or 3 months of hormone therapy, the oncologist submits a new request for whole-body MRI and PET-CT. The MRI and PET-CT should conclude to a status : progression, stability, partial response, complete response. The reading grid is completed again. MDA criteria (MRI and PET-CT), PERCIST and EORTC (PET-CT only) are determined. Target lesions (1 to 3) are defined for each examination and a measure of the ADC and the SUV is performed for each lesion on the initial and follow-up examinations.
After these examinations, the patient is reviewed by his oncologist for a new clinical examination, the announcement of the status of bone metastasis and the possible adaptation of the treatment.
