This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.
Background: Millions of people each year sustain injuries, have tumors surgically removed, or are born with defects that require complex reconstructive surgeries to repair. In the case of hand, forearm, or arm amputation, prostheses only provide less than optimal motor function and no sensory feedback. However, hand and arm transplantation is a means to restore the appearance, anatomy, and function of a native hand. Although over 70 hand transplants have been performed to date and good functional results have been achieved, widespread clinical use has been limited due to adverse effects of life-long and high-dose immunosuppression needed to prevent graft rejection. Risks include infection, cancer, and metabolic problems, all of which can greatly affect recipients' quality of life, make the procedure riskier, and jeopardize the potential benefits of hand transplantation. Study Design: This non-randomized, Phase II clinical trial will document the use of a new immunomodulatory protocol (aka - Pittsburgh Protocol, Starzl Protocol) for establishing hand transplantation as a safe and effective reconstructive treatment for upper extremity amputations by minimizing maintenance immunosuppression therapy in unilateral and bilateral hand/forearm transplant patients. This protocol combines lymphocyte depletion with donor bone marrow cell infusion and has enabled graft survival using low doses of a single immunosuppressive drug followed by weaning of treatment. Initially designed for living-related solid organ donation, this regimen has been adapted for use with grafts donated by deceased donors. The investigators propose to perform 30 human hand transplants employing this novel protocol. Specific Aims: 1) To establish hand transplantation as a safe and effective reconstructive strategy for the treatment of upper extremity amputations; 2) To reduce the risk of rejection and enable allograft survival while minimizing the requirement for long-term high dose multi-drug immunosuppression. Significance of Research: Hand transplantation could help upper extremity amputees recover functionality, self-esteem, and the capability to reintegrate into family and social life as "whole" individuals. The protocol offers the potential for minimizing the morbidity of maintenance immunosuppression, thereby beneficially shifting the risk/benefit ratio of this life-enhancing procedure and enabling widespread clinical application of hand transplantation.
