If a patient withdraws from further follow-up a trial deviation form should be submitted to Oncogenetics Team stating whether the patient has withdrawn consent for information to be sent to the Oncogenetics Team or whether they simply no longer wish to attend trial follow up visits. In the very rare event that a patient requests that their data is removed from the study entirely, the implications of this should be discussed with the patient first to ensure that this is their intent and, if confirmed, the Oncogenetics Team should be notified in writing. If this request is received after results have been published the course of action will be agreed between the Sponsor and Independent Data Monitoring and Steering Committee.
