Brief Summary
RATIONALE: Morphine may reduce pain in patients who have undergone radiofrequency ablation to remove bone metastases. PURPOSE: This phase II trial is studying how well morphine works after radiofrequency ablation of painful bone metastases in patients with cancer.

Outcome Measures
Primary Outcomes (1)
Percentage of Participants With Maximum Pain Level Decreased by ≥ 2 Points at 2 Months After Radiofrequency Ablation (RFA)
Difference in maximum pain scores between inclusion and 2 months after radiofrequency ablation (RFA) according to an 11-point numerical scale Rate of patients with a decrease of two or more points in their most intense pain, 2 months after the radiofrequency ablation. This rate is calculated for the evaluable population for the principal outcome measure. This rate is equal to the ratio of the number of patients with a decrease of two or more points in their maximum pain divided by the size of the evaluable population. The response rate considered acceptable is 50%, above this threshold the treatment will be considered potentially effective and may be proposed in phase III.

Study Arms (1)
Patient who has undergone radiofrequency ablation of bone metastases
EXPERIMENTALPatient who has undergone radiofrequency ablation of bone metastases, localized, causing pain refractory to radiotherapy or not accessible to new irradiation, biphosphonates and well-conducted morphine analgesic treatment.
Interventions
Intravenous administration of paracetamol (4 g / 24h) and patient-controlled analgesia (PCA).
Patient-controlled analgesia (PCA), allowing morphine consumption to be titrated to the patient's needs and thus allowing morphine doses to be adapted to an increase in pain in the patient's post-operative period or a rapid analgesic effect of radiofrequency.
Pain notebook will allow the patient to describe the pain specific to the metastasis concerned, containing information on : * The intensity of the minimum, average and maximum pain of the last 24 months. hours as well as the intensity of the pain of the moment according to a scale 11-point digital, * the background morphine analgesic treatment during the last 24 hours, * the morphine analgesic treatment taken during painful attacks, * the possible undesirable effects of morphine treatment. * the morphinic, non-morphinic and co-antalgic treatment is noted, as well as that the total dose of oral morphine or oral morphine equivalent
Patients' quality of life will be assessed using the quality of life questionnaire EORTC QLQ-C30 at inclusion in the study and at 8 weeks after radiofrequency. ablation.
Recent technique of thermal destruction of tumors. This technique consists of inserting an electrode needle into the tumour under X-ray or ultrasound guidance or intraoperatively under laparoscopy for example. This needle carries a current or a light wave depending on the characteristics of the generator to which it is connected (radiofrequency, laser). Radio frequencies are radiation non-ionising electromagnets. In this context of tissue ablathermia wavelengths ranging from 400kHz to 500kHz.
