Most reports of chronic GVHD after cord blood transplantation (CBT) have utilized traditional diagnostic criteria. We used traditional criteria and National Institutes of Health (NIH) criteria prospectively to evaluate chronic GVHD in a cohort of 87 adult and pediatric recipients of single or double unrelated CBT for treatment of hematologic malignancies. Fifty-four patients developed traditionally defined chronic GVHD, for an estimated 2-year probability of 64%. Among 54 patients, 25 (46%) met the NIH criteria for persistent, recurrent or late acute GVHD at onset. Twenty-four (44%) had overlap chronic GVHD, including one who presented initially with late acute GVHD, and only seven (13%) had classic chronic GVHD, including one who also presented initially with late acute GVHD. Among patients who successfully discontinued all systemic immunosuppression (SI), the median time to discontinuation of corticosteroid treatment was 315 days (range 28-977), and the median time to discontinuation of all SI was 353 days (range 67-977). Chronic GVHD diagnosed by traditional criteria after CBT had a predominance of acute GVHD clinical features.

Introduction: Graft-versus-host disease (GvHD) remains a major complication of allogeneic stem cell transplantation (allo-SCT), affecting 30-70% of patients (representing 800 new patients per year in the UK). The risk is higher in patients undergoing unrelated allo-SCT. About 1 in 10 patients die as a result of GvHD or through complications of its treatment.

Donor-specific antibodies (DSAs) are essential causes of graft rejection in haploidentical hematopoietic stem cell transplantation (haplo-HSCT). DSAs are unavoidable for some patients who have no alternative donor. Effective interventions to reduce DSAs are still needed, and the cost of the current therapies is relatively high.

Chronic Graft-versus-host disease (GVHD) is a major complication of allogeneic hematopoietic stem cell transplantation (HSCT), affecting the female genital tract in 25-66% of the patients. This condition, referred to as Genital GVHD is an underdiagnosed gynecologic comorbidity, that can significantly impair quality of life. We aimed to describe the prevalence and management of genital GVHD following HSCT.

Methods: Data from 402 patients who underwent either PBSCT ( = 294) or BMT ( = 108) between 2000 and 2022 were analyzed using the Japanese nationwide registry database. The primary endpoint was overall survival (OS), and secondary endpoints included disease-free survival (DFS), non-relapse mortality (NRM), and GVHD.
We examined the risk of subsequent malignant neoplasms (SMNs) in 1720 patients with hematologic cancers given allogeneic hematopoietic grafts from 03/1998 to 08/2023 after nonmyeloablative conditioning regimens. With a median follow-up of 12 years, the cumulative incidence of SMNs was 17% (95% CI, [15%, 19%]). Most SMNs (n = 543) were non-melanoma skin cancers seen in 208 patients; unfortunately, information on these cancers was not available in the Surveillance, Epidemiology, and End Results (SEER) database for comparison with such tumors in the general population.
