Assessing the relationship between oral chronic graft-versus-host disease and global measures of quality of life

Assessing the relationship between oral chronic graft-versus-host disease and global measures of quality of life

Summary

Objective

Chronic GVHD (cGVHD) is a frequent complication of allogeneic hematopoietic stem cell transplantation (HSCT) and affects multiple organ systems, with the oral cavity being one of the most frequently affected sites. Patients with cGVHD experience reduced quality of life (QOL), yet the specific impact of oral cGVHD on QOL is poorly understood. The objective of this study was to characterize the impact of oral cGVHD on global measures of QOL.

Materials and methods

QOL data were collected using the FACT-BMT and SF-36 instruments for 569 patients enrolled in the Chronic GVHD Consortium, with a total of 1915 follow-up visits. At study enrollment, patients were categorized as isolated oral cGVHD (n = 22), oral and concomitant extra-oral cGVHD (n = 420), and only extra-oral cGVHD (n = 127). Utilizing all longitudinal data, QOL scores were compared using a multivariable linear model controlling for demographic, transplant, and cGVHD characteristics.

Results

Patients with isolated oral cGVHD reported better physical well-being (P = 0.009), BMT well-being (P = 0.01), and decreased bodily pain (P = 0.01) compared to patients with oral and concomitant extra-oral cGVHD, but the differences in scores did not reach the defined threshold for clinical significance (6 points for FACT-BMT domains and 5 points for SF-36 domains).

Conclusions

Global QOL scores are similar in patients with isolated oral cGVHD and patients with oral and concomitant extra-oral cGVHD.
