The primary objective of this study is to describe the administration practices of the antalgic Ketamine in French CLCC (Centre de Lutte Contre le Cancer) in terms of indication (neuropathic sequelae pains, morphine additional effect or morphine withdrawal, intensity, localisation…) and administration protocol (route, posology, duration, administration sequence, premedication).
The secondary objectives are to evaluate in the context of cancer, the analgesic efficacy, the tolerance profile (biological and clinical toxicities) and the quality of life, including anxiety and depression.
In addition, the described parameters will be evaluated as safety and efficacy predictive factors of the Ketamine in oncology.
