Graft-versus-host disease in the female genital tract: a prospective cohort study.

BACKGROUND

Graft-versus-host disease (GVHD) is the main complication of allogeneic hematopoietic stem cell transplantation (HSCT). GVHD in the female genital tract can cause sinusorrhagia, dyspareunia, synechia, and even complete vagina occlusion.

PURPOSE: This prospective study aimed to evaluate the clinical characteristics and effects of preventive and prompt treatment for genital GVHD in females undergoing HSCT (n = 40).

RESULTS

Genital GVHD was diagnosed in 11 of 40 patients (27.5%), and the most common complaint was vaginal dryness (54.6%). The majority of patients (63.6%) presented mild genital GVHD (clinical score 1), with interlabial fissures and lichen-like lesions, while a minority of patients (9.1%) presented advanced genital GVHD (clinical score 3) with the fusion of the small and large lips. The median time of onset of genital GVHD signs was 10 months after HSCT, concomitant with GVHD in the skin and oral cavity. Personalized and topical therapy was effective in most cases (81.8%), and no patient required surgical intervention.

CONCLUSION

We confirmed that female genital GVHD affects approximately one-third of females undergoing HSCT, highlighting the importance of periodic gynecological monitoring for early detection and treatment to improve care for these females.
