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.
