Objective To understand the continuing care needs of patients with liver cancer undergoing immunotherapy and to provide a reference for the formulation of continuing care strategies in clinical practice. Methods Using the purposive sampling method, 17 liver cancer patients receiving immunotherapy were selected for semi-structured in-depth interviews, and content analytical method was applied for data analysis and theme extraction. Results A total of 4 themes and 14 sub-themes were extracted:the need to alleviate physical discomfort (digestive system discomfort symptoms, skin discomfort symptoms, systemic discomfort symptoms, and neurological discomfort symptoms)；the need for guidance on a healthy lifestyle (diet guidance needs, rehabilitation exercise guidance needs, sleep promotion needs, and information support needs related to immunotherapy)；psychosocial support needs (family support needs, social participation needs, and emotional self-regulation needs)；social environmental support needs (the need to reduce economic burden, the need for support from community health resources, and the need for multi-channel continuing care). Conclusion Patients with liver cancer undergoing immunotherapy have a high demand for continuing care services, and the needs are individualized and diverse. Medical staff need to pay attention to symptom management of patients, strengthen health lifestyle education, pay attention to patients′ negative thinking and social participation, and construct and implement a continuing care plan that matches supply and demand based on the continuing care needs of patients.
