ABSTRACT
Novel therapeutic options for cancer offer hope for patients and their families, particularly when the cancer has not responded to established treatment regimens. The CAR-T cell therapeutic approach has changed the treatment paradigm for relapsed or refractory lymphoma, extending the capacity of the patient's own T cells to detect and eliminate cancer cells through genetic modification of T-cell surface receptors. The process of establishing treatment centers and developing clinical expertize in this novel treatment strategy is complex. Time, resources, and a commitment to focusing health budgets on a new area are required. Currently, Singapore is the only country in southeast and south Asia with market authorization of the CAR-T product, tisagenlecleucel. Availability of CAR-T treatment across international borders provides patients in neighboring countries with choice in therapeutic options. This paper describes the unique hub-and-spoke cross-border collaboration developed between Singapore and its neighbors to provide access to CAR-T cell therapy for patients with relapsed or refractory lymphoma. To date in 2022, four patients have been included in the CAR-T treatment cross-border collaboration. Their stay in Singapore has been at least 2 months' duration, including the pre-treatment evaluation, apheresis, CAR-T cell infusion and post-treatment monitoring. Patient support from referring and treating physicians, critical to the success of the undertaking, is characterized by early communication, patient selection, multi-disciplinary care, post-treatment monitoring, and attention to detail. The patient journey and the development and implementation of this unique collaboration are discussed.
