Evaluating health perceptions of soft-tissue sarcoma patients using the Wilson-Cleary Model to identify key targets for improving outcomes and quality of care

Introduction

Soft-tissue sarcoma (STS) is a rare cancer of the connective tissues requiring invasive treatment. Due to the complexity of treatment, STS patients experience more functional impairment and disability than other oncologic populations. Given that extant literature is unclear and exclusively focused on physical function, the objectives of this study were to use the Wilson-Cleary Model of HRQL to evaluate the extent to which biological function (tumor site, depth and size), symptoms (fatigue, pain, anxiety/depression), and functional status are associated with the health perceptions of soft-tissue sarcoma patients 12 months post-op.

Methods

Data were drawn from an inception cohort study at the McGill University Health Centre. Inclusion criteria included 18 years of age and a biopsy-confirmed diagnosis of STS. Those with evidence of metastasis at diagnosis or less than 12 months of follow-up were excluded. Statistical analyses included T-tests, Pearson correlations, and multiple linear regression.

Results

331 patients were included (185 males, 146 females) with mean (SD) ages of 56 (17). Significantly more females reported pain and anxiety/depression. Self-reported function was significantly higher in males. Overall, the regression model explained 53 % of the variance in health perceptions in males, and 48 % in females. Only self-reported function was significantly associated with health perceptions in males (B = 0.34) and females (B = 0.48). Further, compared to females without pain, females with pain perceived their health as significantly worse.

Conclusion

Evaluating health perceptions with a multidimensional lens revealed new information about the STS patient experience. Findings suggest that key targets include routine psychosocial distress monitoring and addressing rectifiable disability-related barriers promptly.
