Background/Objectives: Hepatocellular carcinoma (HCC) is a major cause of cancer-related mortality worldwide, with transarterial chemoembolization (TACE) commonly used as a palliative approach for patients who are not candidates for surgical resection. Understanding the factors that influence health-related quality of life (HRQoL) after TACE is essential for improving patient-centered care. This systematic review seeks to consolidate current evidence on the variables that impact HRQoL in HCC patients post-TACE. Methods: In adherence to PRISMA guidelines, a comprehensive search was conducted across five English and Chinese databases-PubMed, Scopus, Web of Science, CNKI, and Wanfang-covering studies from database inception to May 2025. Eligible studies were observational and examined factors affecting HRQoL in post-TACE HCC patients. Two independent reviewers performed screening, data extraction, and quality assessment using the Joanna Briggs Institute (JBI) Critical Appraisal Tools. Results: Nine studies met the inclusion criteria, including six cohort studies and three cross-sectional studies. The quality assessment rated seven studies as high quality and two as moderate. A range of validated HRQoL assessment tools was used, with the EORTC QLQ-C30 and FACT-G being the most commonly employed. The factors influencing HRQoL were grouped into five categories: (1) demographic factors (e.g., age, gender, education level); (2) clinical indicators (e.g., liver function, tumor burden); (3) psychological factors (e.g., depression, anxiety, spiritual well-being); (4) social support (e.g., financial status, coping mechanisms); and (5) physical symptoms (e.g., fatigue, pain, appetite loss). Across studies, both symptom severity and psychological distress were consistently associated with lower HRQoL. Conclusions: The HRQoL of HCC patients following TACE is influenced by a complex interplay of demographic, clinical, psychological, social, and symptomatic factors. Tailored, multidimensional interventions addressing these diverse aspects are crucial to optimizing recovery and improving overall well-being.
