Objective:To explore the efficacy and safety of ibrutinib for the treatment of newly treated and relapsed refractory (R/R) lymphoplasmacytic lymphoma (LPL) /Waldenstr?m 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.

Objective To observe the improvement of motor dysfunction and serum levels of C-reactive protein(CRP),blood glucose and blood lipid in post-stroke patients treated with scalp acupuncture at different needle retention time.Methods A total of 120 patients with motor dysfunction after stroke were randomly divided into control group,observation group 1 and observation group 2,with 40 cases in each group.The patients in the 3 groups were treated with scalp acupuncture,body acupuncture and routine rehabilitation exercise,once a day and 6 times a week,lasting for 2 weeks.The control group was given scalp acupuncture with retaining of needles for 30 minutes,the observation group 1 was given scalp acupuncture with retaining of needles for one hour,and the observation group 2 was given scalp acupuncture with retaining of needles for 2 hours.Before and after treatment,the 3 groups were observed in the changes of the scale scores of National Institutes of Health Stroke Scale(NIHSS),Fugl-Meyer Assessment(FM A),Berg Balance Scale(BBS)and modified Barthel Index(MBI),and the levels of laboratory indicators of peripheral blood CRP,fasting plasma glucose(FPG),total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C)and low-density lipoprotein cholesterol(LDL-C).After treatment,the clinical safety of the three groups was evaluated.Results(1)After treatment,the scale scores of NIHSS in the three groups were lower(P＜0.01)and the scale scores FMA,BBS and MBI were higher than those before treatment(P＜0.05 or P＜0.01).The comparison of post-treatment scale scores showed that the differences among the three groups were statistically significant(P＜0.01).The intergroup comparison showed that the decrease of NIHSS score and the increase of FMA,BBS and MBI scores in the observation group 2 were significantly superior to those in the control group and the observation group 1(P＜0.01);the improvement of FMA score in the observation group 1 was significantly superior to that in the control group(P＜0.01),while the improvement of NIHSS,BBS and MBI scores tended to be superior to that in the control group without statistically significant differences(P＞0.05).The results indicated that the curative effect of scalp acupuncture plus exercise regimen was positively correlated with the duration of needle retention for scalp acupuncture.(2)After treatment,the laboratory indicator levels of CRP and FPG in the peripheral blood of the three groups,the levels of TG and LDL-C in the two observation groups and the level of HDL-C in the observation group 2 were improved compared with those before treatment(P＜0.05 or P＜0.01).Statistically significant differences were presented in the post-treatment levels of CRP and TG in peripheral blood among the three groups(P＜0.05 or P＜0.01).The intergroup comparison showed that the improvement of CRP and TG levels in the observation group 2 was significantly superior to that in the control group,and the improvement of CRP level in the observation group 2 was significantly superior to that in the observation group 1,the differences being statistically significant(P＜0.05 or P＜0.01).The TC level in the three groups after treatment did not differ from that before treatment,and there was no significant difference in TC level after treatment among the three groups either(P＞0.05).(3)During the treatment,no adverse reactions such as fainting,needle breaking and hematoma occurred in the three groups,the vital signs of the patients were stable,and there were no obvious abnormal changes in pulse,blood pressure and respiratory rate.Conclusion Scalp acupuncture can effectively improve the motor function of post-stroke patients in a pasitive time-effect relationship with the needle retention,and better the curative effect can be achieved by retaining of the needle for 2 h.

Objective:To explore the clinical short-term efficacy of venetoclax (Ven) combined with azacitidine (AZA) in treatment of newly treated and relapsed/refractory patients with acute myeloid leukemia (AML).Methods:The data of 18 newly treated and relapsed/refractory patients with AML who received Ven+AZA treatment in Suzhou Traditional Chinese Medicine Hospital Affiliated to Nanjing University of Chinese Medicine from April 2020 to June 2022 were retrospectively analyzed. The complete remission or complete remission with incomplete recovery of blood cell count (CR/CRi) and objective remission rate (ORR) [calculated as CR/CRi+partial remission (PR)] were analyzed in newly treated and relapsed/refractory patients or patients with different gene mutations. The patients were followed up until June 30, 2022, and the overall survival (OS) of relapsed/refractory patients was analyzed. The occurrence of adverse reactions was summarized.Results:The median age of the 18 patients was 58 years old (23-81 years old), 8 were males and 10 were females; 6 were newly treated and 12 were relapsed/refractory; the median follow-up time was 3 months (1-15 months). In 6 newly treated patients, after the first cycle of Ven+AZA, 5 cases achieved CR/CRi, and the ORR was 83.3% (5/6). In 12 relapsed/refractory patients, after the first cycle of Ven+AZA, 5 cases achieved CR/CRi, 3 achieved PR, and the ORR was 66.7% (8/12). Among the 18 patients, 7 cases had FLT3-ITD/TKD mutation, after the first cycle of Ven+AZA, 1 case achieved CR/CRi, 1 case achieved PR, and the ORR was 28.6% (2/7); 3 cases had NPM1 mutation combined with FLT3-ITD/TKD mutation, 1 case achieved CR/CRi, and the ORR was 33.3% (1/3); 4 cases had IDH1/2 mutation, and 3 cases of them combined with FLT3-ITD/TKD mutation, all of which were non-remission, and the other 1 relapsed/refractory patient combined with K/NRAS mutation achieved CR/CRi; among the 4 cases with K/NRAS mutation, 2 cases combined with FLT3-ITD/TKD mutation, including 1 case of NR and 1 case of PR, and the other 2 cases achieved CR/CRi, the ORR was 75.0% (3/4). Of the 12 relapsed/refractory patients, 6 died by the end of follow-up, with a median OS time of 2.6 months (1- 8 months), including 4 cases of disease progression and 2 cases of disease relapse; the 6 surviving patients had stable disease. All the 18 patients had ≥grade 3 hematologic adverse reactions, and non-hematologic adverse reactions included lung infection, nausea, vomiting and diarrhea.Conclusions:Ven+AZA treatment for newly treated and relapsed/refractory AML patients results in a high response rate with tolerable adverse reactions, but it is not effective in AML patients with FLT3-ITD/TKD mutation.

Objective:This retrospective, single-center study aimed to evaluate the efficacy and safety of programmed death-1 (PD-1) inhibitors, either as monotherapy or in combination with chemotherapy, in the management of relapse/refractory classical Hodgkin's lymphoma (R/R cHL) .Methods:A total of 35 patients with R/R cHL who received treatment at the Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College from September 2016 to December 2020 were enrolled in this study. Among them, 17 patients received PD-1 inhibitor monotherapy (PD-1 inhibitor group), while 18 patients received a combination of PD-1 inhibitor and chemotherapy (PD-1 inhibitor + chemotherapy group). Clinical data and follow-up information were retrospectively analyzed, and survival analysis was conducted using the Kaplan-Meier method and Cox proportional hazards model.Results:The median age of the 35 patients with R/R cHL was 29 years (range: 11-61 years), with 54.3% being male. According to the Ann Arbor staging system, 62.9% of patients presented with advanced (stage Ⅲ/Ⅳ) disease, and 48.6% had extranodal involvement. Before PD-1 inhibitor therapy, the median number of prior lines of therapy was 2 (range: 1-3). Objective responses were observed in 28 patients, including 22 complete response (CR) cases, resulting in an overall response rate (ORR) of 80.0% and a CR rate of 62.9%. Specifically, the ORR and CR rates were 64.7% and 58.8%, respectively, in the PD-1 inhibitor group and 94.4% and 66.7%, respectively, in the PD-1 inhibitor + chemotherapy group. Among the 18 patients who underwent sequential autologous hematopoietic stem cell transplantation (auto-HSCT) [13 CR and five partial response (PR) cases], eight patients received PD-1 inhibitor therapy after auto-HSCT as consolidation therapy. All patients maintained a CR status after transplantation, and they exhibited significantly improved progression-free survival (PFS) rates compared with those who did not undergo sequential auto-HSCT (4-year PFS rates: 100% vs 53.5% ; P=0.041). The incidence of immune-related adverse events was 29%, with only one patient experiencing grade≥3 adverse reactions, which indicated a favorable safety profile for the treatment approach. Conclusions:PD-1 inhibitor monotherapy demonstrates notable efficacy and sustained response in patients with R/R cHL. PD-1 inhibitors combined with chemotherapy significantly improve response rates. Additionally, for salvage therapy-sensitive patients, consolidation treatment with PD-1 inhibitors after auto-HSCT exhibits the potential for prolonging PFS.

Objective: This study aimed to determine the efficacy of dose-enhanced immunochemotherapy followed by autologous peripheral blood stem cell transplantation (ASCT) in young patients with newly diagnosed high-risk aggressive B-cell lymphoma. Methods: A retrospective study was conducted to examine the clinical and survival data of young patients with high-risk aggressive B-cell lymphoma who received dose-enhanced immunochemotherapy and ASCT as first-line treatment between January 2011 and December 2018 in Blood Diseases Hospital. Results: A total of 63 patients were included in the study. The median age range was 40 (14-63) years old. In terms of the induction therapy regimen, 52 cases received R-DA-EP (D) OCH, and the remaining 11 received R-HyperCVAD/R-MA. Sixteen (25.4% ) patients achieved partial response in the mid-term efficacy assessment, and ten of them were evaluated as complete response after transplantation. The median follow-up was 50 (8-112) months, and the 3-year progression-free survival (PFS) rate and overall survival (OS) rate were (83.9±4.7) % and (90.4±3.7) % , respectively. Univariate analysis demonstrated that age-adjusted international prognostic index ≥2 scores was a negative prognostic factor for OS (P=0.039) , and bone marrow involvement (BMI) was an adverse prognostic factor for OS (P<0.001) and PFS (P=0.001) . However, multivariate analysis confirmed that BMI was the only independent negative predictor of OS (P=0.016) and PFS (P=0.001) . Conclusions: The use of dose-enhanced immunochemotherapy in combination with ASCT as first-line therapy in the treatment of young, high-risk aggressive B-cell lymphoma results in good long-term outcomes, and BMI remains an adverse prognostic factor.

OBJECTIVE: To investigate the clinical value of oligoclonal bands (OB) in patients with multiple myeloma (MM). METHODS: The laboratory test and clinical data of 624 newly diagnosed MM patients admitted to Blood Diseases Hospital of Chinese Academy of Medical Sciences from January 2013 to December 2019 were retrospectively analyzed, including 30 patients with OB, and the clinical characteristics, treatment effects and survival of OB and non-OB patients were analyzed and compared. RESULTS: OB occurred in 11.8% (22/187) of patients who received autologous stem cell transplantation(ASCT) and only 1.8% (8/437) of patients who did not receive ASCT (P=0.000). The median time to the appearance of oligoclonal bands was 3.2(0.6-10.5) months after transplantation. The M protein types of oligoclonal bands mainly include IgG κ, IgG λ, IgM λ and λ light chains. In the presence of oligoclonal bands, 90% of patients were evaluated as complete remission (CR) and above. There were no statistically significant differences in disease stage, tumor burden, and genetic abnormalities between OB and non-OB patients. Among the all patients, the prognosis of OB patients was significantly better than that of non-OB patients, and OB patients showed deeper disease remission (significantly higher CR rate, MRD negative rate, and longer MRD negative duration). Among patients who underwent ASCT, OB patients showed earlier immune recovery, but the depth of treatment response and survival outcomes were similar between OB and non-OB patients, it was no statistically difference. Although OB patients showed earlier immune reconstitution, this did not translate into better survival, suggesting that the better prognosis of OB patients was mainly related to deeper and durable remission rather than early immune reconstitution. Further analysis in patients who received ASCT and obtained MRD negative indicated that there was no additional survival benefit in patients with OB. CONCLUSION The better prognosis of OB patients may be related to the deeper treatment response, but not to the early immune reconstitution. The appearance of OB is only a sign of deep remission and early immune reconstitution in patients, it cannot be translated into survival benefit of MM patients.
