Bliss DTx Assessment During Course Care Including Port-A-Catheter Setting

Setting a Port-a Cath is performed in a surgical room, under ambulatory, by a specialist, under local anesthesia. This Port-a Cath is placed in the upper part of the thorax, under the clavicle, and facilitate the administration of certain anticancer drugs or to inject other treatments throughout the course of care. Setting a Port-a Cath is painful and stressful. In addition to local anesthesia, patients are often offered a sedation: anxiolytics, hypnotics or inhalation of MEOPA. Butterfly Therapeutics has developed a Digital Therapeutics (DTx) called Bliss DTx which uses virtual reality augmented by sound and visual stimuli. A first clinical study with Bliss DTx showed that the pain level was not significantly different between "Bliss DTx" arm and "MEOPA" arm when performing osteomedullary biopsy. This study is based on the hypothesis that Bliss DTx use would : * Be clinically equivalent to a standard protocol (use of hypnotics and/or anxiolytics and/or MEOPA and/or hypnosis conversational) to manage pain during Port-a Cath setting under local anesthesia * Reduce anxiety before setting a Port-a Cath * Provide greater satisfaction with the treatment process from patient point of view * Have organizational impacts, some of which could be economically valued
