Abstract

Purpose: Graft-versus-host disease (GVHD) is an important complication of allogeneic hematopoietic stem cell transplantation (AHCT) that affects several organs, including the mouth.

Objectives: The aim of the present study was to describe the prevalence and clinical manifestations of oral GVHD, to determine the time interval from AHCT to the onset of oral GVHD manifestations, to identify predictive factors of oral GVHD, and to evaluate the survival rates of patients diagnosed with oral GVHD.

Methods: Medical records of 147 patients who underwent AHCT between January 2010 and January 2015 were reviewed for clinical features and the statistical establishment of risk factors.

Results: Of the 147 patients in the study, 99 (67.3%) developed GVHD. The skin was the most affected site (45.6%), followed by the gastrointestinal tract (27.9%) and oral cavity (17.7%). The mean post-AHCT oral GVHD development time was 229 days. Among patients with oral GVHD, pain was the main complaint (96.2%) followed by xerostomia (65.4%). The most common oral manifestations were ulcers (53.8%) followed by striae-associated ulcers (19.2%), mostly affecting the buccal mucosa and tongue. Seventy-three patients (48.6%) died within 20 months of receiving AHCT. Cox regression analysis indicated that patients who received myeloablative conditioning regimen had higher survival rate than those who underwent a reduced-intensity conditioning regimen (RR = 0.541; 95% CI, 0.334-0.878; p = 0.03).

Conclusion: The mouth was the third most common GVHD-affected site. Pain, xerostomia, and ulcers with or without striae were the main clinical manifestations of GVHD observed in our study cohort. Reduced-intensity conditioning regimen showed significant relationship with mortality risk.
