关于 CAR-T 细胞治疗的沟通

Chimeric Antigen Receptor T-cell (CAR-T) therapy has revolutionized the treatment of patients with hematologic malignancies, yet treatment may coincide with the potential for life-threatening toxicities. Currently, no studies have investigated how oncologists communicate with patients about CAR-T therapy or what patients and their caregivers want to know prior to consenting for CAR-T therapy.

This study characterizes the content of oncologist communication with patients and caregivers about the risks and benefits of CAR-T therapy and explore the information preferences of patients and their caregivers about CAR-T therapy.

We conducted a multimethod study of 20 patients with hematologic malignancies referred for CAR-T therapy at the Massachusetts General Hospital and 10 caregivers.

We audio recorded the initial outpatient visit with the oncologist to review and sign consent for CAR-T therapy.

We subsequently surveyed patients and caregivers about information gaps that remained after consent.

We then interviewed patients and caregiver about their perceptions of oncologist communication and information preferences after the consent visit, 1 month, and 3 months post-CAR-T therapy treatment. Qualitative data analysis was conducted using the framework approach.

Six major themes regarding communication about CAR-T therapy were identified: (1) oncologists create a narrative of power and innovation about CAR-T therapy, (2) oncologists set clear expectations regarding CAR-T therapy, (3) oncologists preferentially discuss positive treatment outcomes and less frequently address treatment failures or uncertainties, (4) oncologists couple their discussion about risks of CAR-T therapy with assurances about risk mitigation strategies, (5) oncologists engage in empathetic communication throughout the consent visit, (6) patients and caregivers vary in their preferences regarding communication about CAR-T therapy but largely favor a positive discourse during the consent visit and (7) patients who completed CAR-T therapy and their caregivers report significant knowledge gaps during and after treatment.

Overall, patients and caregivers felt well informed about CAR T-therapy yet identified communication gaps regarding, advanced care planning, treatment failure and treatment toxicities. A predominantly positive discourse between patients, caregivers, and oncologists around CAR-T therapy leaves patients and caregivers with significant knowledge gaps about negative outcomes.

Further research is needed to help oncologists communicate about treatment uncertainties and help patients and their caregivers prepare for negative outcomes of CAR-T therapy.
