Effectiveness of hypnotherapy with cancer patients' trajectory: emesis, acute pain, and analgesia and anxiolysis in procedures.

Clinical hypnosis in cancer settings provides symptom reduction (pain and anxiety) and empowers patients to take an active role in their treatments and procedures. The goal of this paper is to systematically and critically review evidence on the effectiveness of hypnotherapy for emesis, analgesia, and anxiolysis in acute pain, specifically in procedures with an emphasis on the period from 1999 to 2006. Further, it aims to provide a theoretical rationale for the use of hypnosis with cancer populations in the whole spectrum of illness/treatment trajectory in several clinical contexts. Finally, a treatment protocol for management of overt anxiety and phobic reactions in the radiotherapy suite is presented, with the intent of having such a protocol empirically validated in the future.
