Longitudinal health-related quality of life after remote-access versus open thyroidectomy for thyroid cancer: a systematic review and meta-analysis
摘要
As remote-access thyroidectomy (RAT) becomes more widely used, evidence on patient- reported outcomes, particularly health-related quality of life (HRQoL), remains scarce and inconsistent. This meta-analysis compared postoperative HRQoL between thyroid cancer (TC) patients undergoing RAT and open thyroidectomy (OT) and assessed changes over time. A comprehensive search of five major databases was conducted from inception to August 2025. Studies reporting HRQoL after RAT or OT were included. Outcomes were grouped by postoperative timepoints. Outcomes were stratified across distinct postoperative timepoints to calculate pooled standardized mean difference (SMD) or mean difference (MD). Heterogeneity was explored through rigorous subgroup analyses encompassing surgical modalities, countries, and assessment instruments. Forty-one studies met the inclusion criteria, and 29 records were included in the quantitative synthesis. RAT demonstrated early advantages in comprehensive quality of life at 1 month and 3 months, and these advantages dissipated long term. Pain trajectories exhibited a biphasic pattern: RAT was associated with lower pain scores on postoperative day 1 but paradoxically higher scores during the 1–2 week period, with subsequent convergence. Cosmetic satisfaction and swallowing function consistently favored RAT from 1–2 weeks through 6 months, while voice outcomes showed no discernible differences. RAT appears to confer selected short- to medium-term patient-reported advantages over OT, particularly in cosmetic satisfaction and swallowing function. But these benefits are heterogeneous and not consistently maintained across all domains or timepoints. Future studies should standardize cross-culturally validated PRO instruments and adopt harmonized follow-up intervals and reporting guidelines to clarify the patient-centered value of RAT.
