Data were retrieved from electronic medical records of FL patients treated at Rambam between 2006 and 2021. The maintenance cohort included 155 patients receiving 165 treatment courses; the non-maintenance cohort included 58 patients receiving 67 courses. Median time on maintenance was 1.81 ± 0.28 years.

Recent studies have shown very favorable outcomes in severe aplastic anemia (SAA) patients, with comparable outcomes to those of patients receiving immune suppressive therapy (IST) and allogeneic HSCT from a matched sibling donor (MSD) or matched unrelated donor (MUD). However, most of the previous studies relied on single-center data analyses, and the conditioning regimen, GVHD prophylaxis and supportive care used were relatively singular. We do not know whether there are differences in the survival of SAA patients after haplo-HSCT and MSD-HSCT under conditions involving different transplant centers, conditioning regimens and GVHD prophylaxis. This is a disease-specific, multicenter and retrospective study. We retrospectively studied 156 consecutive patients with SAA who underwent haplo-HSCT or MSD-HSCT at four transplant centers in China. The 5-year overall survival (OS) rate was 87.5% in the haplo-HSCT group and 89.7% in the MSD-HSCT group. The time to hematopoietic reconstitution, incidence of graft versus host disease, and infection and graft failure rates were not significantly different between the groups. Haplo-HSCT achieved outcomes comparable to those of MSD-HSCT for SAA patients. According to the nomogram score, we developed a SAA prognostic scoring system.

A 58-year-old male who received UCBT for peripheral T-cell lymphoma presented progressive anemia and thrombocytopenia, and leukocytosis with blast cells in the peripheral blood (PB).

Importantly, a minor clone with the same GATA1 mutation was detected in UCB by droplet digital PCR. DC-TAM is a rare UCBT-related complication which resembles MDS, but the identification of GATA1 mutation may be useful for its diagnosis.

Despite its approval for ages 12-18, there is limited pediatric data available. This case series presents three 12-year-old patients with severe cGVHD who had failed multiple lines of therapy. Case #1 received treatment for 210 days with belumosudil, prednisone, cyclosporine A, mycophenolate mofetil, and ruxolitinib. Initial assessments showed skin and joint fascia involvement (National Institutes of Health score 3), along with oral cavity, ocular, and pulmonary involvement (score 2). Following treatment, all affected organs demonstrated at least a partial response (PR), with an overall assessment of PR. Case #2 was treated for 205 days with belumosudil, tacrolimus, and ruxolitinib. Baseline assessments indicated involvement of the skin and joint fascia (score 3), and the oral cavity and eyes (score 2). Most organs achieved PR or complete response (CR), resulting in an overall PR. Case #3 underwent 121 days of therapy with belumosudil, prednisone, and tacrolimus, showing similar baseline organ involvement as Case #2. The treatment resulted in an overall PR, with improvement noted in the skin, oral cavity, eyes, and joint fascia. The Lee cGVHD symptom scale scores improved meaningfully for all patients over time. There was no recurrence of the primary disease or any fatalities. Adverse events were limited to grade 1-2 severity. This case series indicates that belumosudil may be effective in 12-year-old pediatric patients with severe, multi-organ cGVHD refractory to multiple treatments. The findings suggest that belumosudil-based regimens can be feasible and well-tolerated in this population, providing preliminary evidence for its potential therapeutic effects in clinical management.</p>","PeriodicalId":8068,"journal":{"name":"Annals of Hematology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142806151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
