Abstract
Background: Pediatric, adolescent, and young adult survivors of bone sarcomas are at risk for poor quality of life (QOL). We conducted a systematic review and meta-analysis to summarize the literature describing QOL in this population and differences in QOL based on local control procedures.
Procedure: Included studies described ≥5 patients <25 years old who had completed local control treatment for bone sarcoma, defined QOL as a main outcome, and measured it with a validated instrument. Data extraction and quality assessments were conducted with standardized tools. Meta-analyses compared QOL based on surgical procedure (limb-sparing vs. amputation) and were stratified by assessment type (objective physical function, clinician-assessed disability, patient-reported disability, and patient-reported QOL). Effect sizes were reported as the standard mean difference when multiple instruments were used within a comparison and weighted mean difference otherwise. All were weighted by inverse variance and modeled with random effects.
Results: Twenty-two of 452 unique manuscripts were included in qualitative syntheses, eight of which were included in meta-analyses. Manuscripts were heterogeneous with respect to included patient populations (age, tumor type, time since treatment) and QOL instruments. Prospective studies suggested that QOL improves over time, and that female sex and older age at diagnosis are associated with poor QOL. Meta-analyses showed no differences in outcomes between patients who underwent limb-sparing versus amputation for local control.
Conclusion: QOL studies among children and AYAs with bone sarcoma are remarkably diverse, making it difficult to detect trends in patient outcomes. Future research should focus on standardized QOL instruments and interpretations.
