The study consists of having participants complete quality of life questionnaires (PROMs) at the time of the cures +/- one week and in the middle of the intercure time +/- one week.

As all the collection times do not correspond to a consultation or a visit to a medical service, The investigator wanted to develop a remote, computerized data collection solution.

Researchers have programmed an AURA-RIV-TNE care pathway (MOCAs: Engine for the organization and coordination of health acts) on the myHCL patient environment, taking up the course of the study presented in the form of a table in paragraph 6.2. Once the patient consents to participate in the study, he must create an account on the patient interface of his investigation center (myHCL, myCHUGA etc) as much as possible to facilitate data extraction.

Once the patient consents to participate in the study, the MOCAs AURA-RIV-TNE course will be associated with him in the Easily software, by defining the date week 0 (baseline) of the first treatment. This will allow automated sending of MAIL and SMS reminders at each questionnaire time. The MAILs will contain an internet link allowing the participant to be directly written to the questionnaires to be completed. A reminder system will be possible if the patient does not complete the questionnaire.
