To determine the efficacy and safety of selinexor combined with venetoclax (VEN) and azactitidine (AZA) for patients with relapsed and/or refractory acute myeloid leukemia (R/R AML) . Twelve patients with R/R AML treated with selinexor plus VEN and AZA in the Affiliated Cancer Hospital of Zhengzhou University from May 2022 to May 2023 were included. Their clinical data were retrospectively analyzed. Among the 12 R/R AML patients, 5 (41.7%) achieved complete remission (CR) , 1 (8.3%) achieved CR with incomplete hematological recovery, and 5 (41.7%) achieved partial remission. The median time to reach CR was 28 (16-59) days. The median PFS was 61 (15-300) days. The main adverse event of the regimen was hematological toxicity. No chemotherapy-related deaths were observed. The combination of selinexor plus VEN and AZA is an effective treatment for R/R AML patients.

A retrospective analysis was conducted on three patients with primary myelofibrosis who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) at Shanghai Zhaxin Traditional Chinese and Western Medicine Hospital from 2020 to 2023. They subsequently developed poor graft function. The patients received selected donor CD34(+) cell boosts as salvage therapy. There were two male patients and one female patient, with a median age of 68 (39-69) years. The median time from allo-HSCT to the selected donor CD34(+) cell boost was 83 (56-154) days. The median infusion of selected donor CD34(+) cells was 7.67 (7.61-9.06) ×10(6)/kg, with a CD34(+) cell purity of 97.76% (96.50%-97.91%) and a recovery rate of 70% (42%-75%) . Hematological recovery was achieved in two cases. No acute GVHD was observed in any of the three patients. One case of moderate oral chronic GVHD was noted. Selected donor CD34(+) cell boosts for the treatment of poor graft function after allo-HSCT in primary myelofibrosis was effective and no severe acute or chronic GVHD was observed.

Objective: To explore the efficacy and safety of ibrutinib for the treatment of newly treated and relapsed refractory (R/R) lymphoplasmacytic lymphoma (LPL) /Waldenström macroglobulinemia (WM) . Methods: Retrospectively collected clinical data of 98 cases of newly treated and R/R LPL/WM patients who received ibrutinib treatment at the Hematology & Blood Diseases Hospital of the Chinese Academy of Medical Sciences from March 2016 to June 2023, and analyzed their efficacy and safety. Results: A total of 98 LPL/WM patients were included, which consisted of 45 newly treated patients and 53 R/R patients. Of these, 74 were males (75.5%) and the cohort had a median age of 64 (42-87) years. Eighty-eight patients were eligible for efficacy evaluation with a median treatment time of 20.8 (2.1-55.0) months, a major remission rate (MRR) of 78.4%, and an overall response rate (ORR) of 85.2%. The MRR and ORR of the newly treated patients were 78.4% and 86.5%, respectively, whereas the MRR and ORR of the R/R patients were 78.4% and 84.3%, respectively. There were no statistically significant differences in MRR and ORR between the initial treatment and R/R patients (all P values >0.05) . The median follow-up period was 29.1 (2.9-50.3) months and the median overall survival time for newly treated and R/R patients was not reached. The median progression-free survival time was 23.5 (95% CI 10.5-36.5) months and 45.0 (95% CI 34.0-56.0) months, respectively, with no statistically significant differences (all P values >0.05) . There were 25 deceased patients and no deaths were related to ibrutinib treatment. The main adverse reactions of ibrutinib were thrombocytopenia (5.1%) , pneumonia (8.1%) , and hyperuricemia (21.4%) . The incidence of atrial fibrillation was 2.0%. Conclusion: Ibrutinib exhibits good efficacy and safety for newly treated and R/R LPL/WM patients.

POEMS syndrome is a rare plasma cell dysplasia. Its clinical manifestations include polyneuropathy, monoclonal protein, increased extravascular volume load, endocrinopathy, organomegaly and skin changes. The complex and atypical symptoms at presentation make early diagnosis challenging due to multiple system involvement. Peripheral neuropathy, limb numbness, is the most common initial symptom of this disease. However, case reports of increased extravascular volume load are rare. This article collected and analyzed the clinical data of two groups of patients with different initial symptoms (increased extravascular volume load and limb numbness). The clinical characteristics and treatment responses were summarized.

The lack of donors is the biggest obstacle to the widespread use of hematopoietic stem cell transplantation. The establishment and improvement of new transplantation schemes have made haploid hematopoietic stem cell transplantation a clinical routine, benefiting a large number of patients with hematological diseases. Haploid donors have become the most important source of donors for allogeneic hematopoietic stem cell transplantation in China. This article focuses on the current situation and future development trends of haploid hematopoietic stem cell transplantation in China, in order to increase the understanding of clinical doctors on haploid hematopoietic stem cell transplantation.

Objective: To investigate the efficacy and safety of liposomal amphotericin B (L-AmB) for the salvage treatment of invasive fungal disease (IFD) in patients with hematological diseases. Methods: Data were retrospectively collected from 80 patients with hematological issues treated with L-AmB between June 2023 and December 2023 after failure of previous antifungal therapy. Baseline patient information, clinical efficacy, and factors affecting the efficacy of L-AmB were analyzed by logistic regression. Moreover, adverse effects associated with L-AmB were evaluated. Results: Among the 80 patients, 9 (11.2%) had proven IFD, 43 (53.8%) had probable IFD, and 28 (35.0%) had possible IFD. The efficacy rate of L-AmB salvage therapy for IFD was 77.5%, with a median daily dose of 3 (range: 1-5) mg·kg(-1)·d(-1) and a median dosing course of 14 (range: 8-25) days. Multivariate logistic regression analysis showed that the disease remission status (OR=4.337, 95% CI 1.167-16.122, P=0.029) and duration of medication (OR=1.127, 95% CI 1.029-1.234, P=0.010) were independent factors affecting the efficacy of L-AmB. The incidence of infusion reactions associated with L-AmB, including fever and chills, was 5.0%. The incidence of hypokalemia was 28.8% (predominantly grades 1-2), and the incidence of nephrotoxicity was 11.3% (predominantly grades 1-2) . Conclusion: L-AmB is safe and effective in the treatment of patients with IFD who are intolerant to or who have experienced no effect of previous antifungal therapy, with a low rate of adverse reactions.

Hepatosplenic candidiasis (HSC) is a rare type of candidiasis that can occur in patients with hematologic malignancies, hematopoietic stem cell transplantation. At present, there is still a lack of studies on HSC in patients with hematologic disorders. Based on The Chinese Guidelines for the Diagnosis and Treatment of Invasive Fungal Disease in Patients with Hematological Disorders and Cancers (the 6th revision), We retrospectively analyzed the clinical characteristics and prognosis of patients with HSC treated in Peking University Institute of Hematology from 2008 to 2022. Finally, eighteen patients were included, with 1 (5.6%) proven, 2 (11.1%) probable, and 15 (83.3%) possible HSC. Among them, 3 (16.7%) patients occurred after haploid hematopoietic stem cell transplantation and 15 (83.3%) patients occurred after chemotherapy. 6 (33.3%) patients had positive blood cultures, including 4 cases of Candida tropicalis and 2 cases of Candida albicans. At 4 weeks of antifungal therapy, 10 (58.8%) patients achieved partial response (PR), At 8 weeks, 1 (6.3%) patients achieved complete response and 10 (62.5%) patients achieved PR. At 6 months after diagnosis, 3 (16.7%) patients died of hematopoietic recurrence, and none of them died of HSC. As a rare fungal infection disease, HSC has a low positive rate of microbiological and histological examinations, a persistent treat cycle, and has difficulty in remission, reminding us of the need for vigilance in patients with hematopoietic disorders and persistent fever.

Objective: This study aims to explore the survival advantages of different maintenance strategies for MCL. Methods: Clinical data of 693 newly diagnosed MCL patients in multi-centers admitted from April 1999 to December 2019 were collected. 309 cases received maintenance treatment. The characteristics of patients in different maintenance treatment groups were summarized and Kaplan-Meier survival and prognosis analysis were conducted. Results: The overall 3-year and 5-year progression-free survival (PFS) rates were (73.5±2.9) % and (53.6±4.3) %, respectively. The 3-year and 5-year overall survival (OS) rates were (94.2±1.5) % and (82.7±3.2) %, respectively. The clinical features of different maintenance treatment groups were generally consistent. The 3-year PFS rates of rituximab maintenance, lenalidomide maintenance, BTK inhibitor maintenance and dual-drug maintenance were (70.4±4.1) %, (69.1±7.6) %, (86.9±5.0) %, and (80.4±5.1) %, respectively. Corresponding 3-year OS rates were (92.9±2.4) %, (97.3±2.7) %, (97.9±2.1) %, and (95.3±2.7) %, respectively. There were no significant difference in different groups (P=0.632, 0.313). Survival analysis identified the MCL International Prognostic Index (MIPI) high-risk group and achieving complete remission before maintenance treatment as independent risk factors for PFS. The MIPI high-risk group, high-dose cytarabine application, treatment lines, and early disease progression (POD24) emerged as independent risk factors for OS. Conclusion: Comparing the different maintenance strategies of MCL, the result showed that BTK inhibitors (BTKi) maintenance demonstrated preliminary advantages in survival. Meanwhile, high-risk group according to MIPI and incomplete remission before maintenance treatment were significant factors related to disease progression.
