Objective·To investigate the efficacy and safety of a dose-reduced,all-oral lenalidomide/melphalan/prednisone acetate(RMP)regimen in elderly and frail patients with newly diagnosed multiple myeloma(NDMM).Methods·Elderly and frail NDMM patients who visited the Department of Hematology of Ruijin Hospital,Shanghai Jiao Tong University School of Medicine,and the Third People's Hospital of Kunshan from April 2018 to March 2024 were retrospectively included.Clinical data and laboratory indicators were collected,and all patients were treated with the RMP regimen.SPSS 27.0 and R software were used for statistical analysis.Independent t-test was applied to normally distributed quantitative data,Mann-Whitney U test to non-normally distributed quantitative data,and x2 test and Fisher's exact probability method to qualitative data.Kaplan-Meier survival curves and Log-rank test were used for survival analysis.Results·Among the 22 elderly and frail NDMM patients treated with RMP,the median age was 76.3(68.4,95.0)years,and the median follow-up time was 25.5 months.The overall response rate(ORR)was 68.2%,and the rate of≥very good partial response(VGPR)was 36.4%.The median progression-free survival(PFS)was 20.53 months.The median PFS in the≤75-year-old group was 25.23(95%CI 12.95?37.52)months,while in the>75-year-old group it was 18.23(95%CI 14.86?21.61)months.There was no significant difference between the two groups.The median PFS in the≥partial response(PR)group was 20.67(95%CI 13.57?27.76)months,and in the

Multiple myeloma (MM) is a malignant disease caused by the abnormal clonal proliferation of plasma cells, accounting for 10% of all hematologic cancers. In recent years, with the development and application of targeted drugs, a significant progress has been observed in the treatment methods of MM, but patients still face the challenges of relapse and drug resistance. Moreover, G protein-coupled receptor class C Group 5 member D (GPRC5D) is highly expressed in MM cells independently of B cell maturation antigen (BCMA) and is a highly promising target following BCMA. Aside from emphasizing the therapeutic efficacy and safety of targeting GPRC5D for the treatment of MM, this study also provides a prospective view on the mechanisms of drug resistance and relapse associated with GPRC5D-targeted therapies, as well as the timing of sequential or combined treatment strategies involving the dual targeting of both GPRC5D and BCMA.

OBJECTIVETo analyse the epidemiological feature, clinical characters and therapeutic regimens for von Willebrand disease(VWD).

METHODSThe clinical data and laboratory tests results of 162 VWD patients in our center were analyzed.

RESULTSThere were 76 males and 86 female among these patients with the mean age of 7.2(2.0-41.0) and 20.7(5.0-48.0) years, respectively. 86 patients (53.1%) were identified to be type 1 VWD, 34 patients (21.0%) type 3 VWD and 42 patients (25.9%) type 2 VWD. Among type 2 VWD patients, 33 patients were type 2A, 4 patients type 2M, 5 patients type 2B. Eighty-seven patients (53.7%) had a definite family history of bleeding tendency. The most common and specific bleeding symptoms were easy bruising (61.7%), epistaxis (53.7%), prolonged bleeding after surgery or minor injury (53.1%). Menorrhagia (66.3%) was common in female patients. The analysis of Vicenza bleeding scores in all patients showed that only 56(34.6%) patients had abnormal bleeding scores. FVIII/VWF concentrates and cryoprecipitate were applied to 45 patients (27.8% ), Desmopressin (DDAVP) to 8 patients. Eight female patients need oral contraceptives jointly to control menorrhagia. Hysterectomy had to be performed in 2 female patients with VWD.

CONCLUSIONVWD was a common congenital bleeding disorder with heterogeneous characters, it was necessary to screen, identify, classify accurately this disease in order to supply to effectively individualized treatment.
