Patients with intractable cancer pain, either uncontrolled with standard analgesia , or undergoing severe side effects due to analgesia . Patients undergo implantation of a Medtronic intrathecal pump and catheter system for delivery of morphine sulfate directly into the spinal fluid as well as clonidine and/or bupivacaine hydrochloride as adjuvants at the discretion of the investigating clinician. 2 way of morphine admisitration will be studied, continous drug flow and PCA. MedDRA version: 9.1

Primary
| Measure | Time frame |
|---|---|
| Main Objective: To prove that intrathecal morphine is more efficient with PCA than a continous drug delivery flow, in patients with intractable cancer pain.;Secondary Objective: To determine that intrathecal morphine is more efficient than prior analgesia with morphine using different way of administration To determine that intrathecal morphine is associated with less severe side effects than other way of morphine administration. To compare to modes of intrathecal morphine delivery (continous or PCA) To determine improvement of quality of life To compare the safety of different intrathecal morphine delivery modes;Primary end point(s): - Pain measurement on a 10 point numeric scale during the day, mean estimated rest pain and actvity pain once a day, catheter complications, morphine side effects, patient's ECOG, adjuvant treatment's side effects (ropivacaine, clonidine), total daily morphine dosage, antalgic consumption | — |
