Objective:To assess the safety and efficacy of thiotepa, busulfan, and etoposide (TBE) conditioning followed by autologous hematopoietic stem-cell transplantation (TBE auto-HSCT) in primary central nervous system lymphoma (PCNSL) patients.Methods:Clinical data from 27 PCNSL patients who received TBE auto-HSCT at the Fifth Medical Center of PLA General Hospital between November 1, 2021, and April 30, 2024, were retrospectively analyzed.Results:Twenty-seven patients [16 males, 11 females; median age 57 (23–72) years] were included, with 12 (44.4%, 12/27) over 60. Twenty-five had newly diagnosed PCNSL and 2 were relapsed. Median time from diagnosis to transplantation was 6.9 (5.0–10.0) months. TBE auto-HSCT increased complete remission (CR) rate from 63.0 to 96.3% ( P= 0.005), and 9 of 10 patients in partial remission achieving CR post-transplant. Median follow-up was 24.5 months (range 2.0–36.0). Two-year progress-free and OS rates were (87.2±6.9) % and (88.6±6.2) %, respectively. Common grade 3 nonhematologic adverse events were diarrhea (18.5%, 5/27) and bacterial infections (14.8%, 4/27). One patient (64 years old) died from carbapenem-resistant Enterobacteriaceae infection within 2 months post-transplant, yielding a 100-day treatment-related mortality of 3.7% (1/27) . Conclusion:TBE-conditioned high-dose chemotherapy with auto-HSCT is effective, safe, and well-tolerated in PCNSL patients, including the elderly.

OBJECTIVE: To observe the clinical efficacy of meridian sinew manipulation releasing technique combined with heat-sensitive moxibustion for simple obesity. METHODS: Twenty-nine patients with simple obesity were selected, on the basis of the conventional treatment, the patients were treated with meridian sinew manipulation releasing technique on the affected meridian sinews in the abdomen and lower limbs, about 30 min a time. After releasing, using the moxibustion sensation localization method in the abdominal regions with high heat-sensitivity frequency (including acupoints such as Zhongwan [CV12], Tianshu [ST25], Qihai [CV6], Guanyuan [CV4]), 2 heat-sensitive acupoints were selected for moxibustion and moxibustion was applied at each acupoint for 40 min, or until the heat-sensitive moxibustion sensation disappeared. The patients were treated once every other day for a total of 20 times. The weight, body mass index (BMI), body fat rate, waist circumference and hip circumference of the patients before and after treatment were observed, and the clinical efficacy was evaluated after treatment. RESULTS: After treatment, the weight, BMI, body fat rate, waist circumference and hip circumference of the patients were decreased compared with those before treatment (P<0.05). The total effective rate was 93.1% (27/29). CONCLUSION Meridian sinew manipulation releasing technique combined with heat-sensitive moxibustion can effectively treat simple obesity, the treatment from the perspective of meridian sinews provides a new idea and plan for simple obesity.

Objective:This study investigated the efficacy and safety of denosumab (DENOS) versus zoledronic acid (ZOL) in the bone disease treatment of newly diagnosed multiple myeloma.Methods:The clinical data of 80 patients with myeloma bone disease (MBD) at the Fifth Medical Center of PLA General Hospital between March 1, 2021 and June 30, 2023 were retrospectively reviewed. Eighteen patients with severe renal impairment (SRI, endogenous creatinine clearance rate<30 ml/min) were treated with DENOS, and 62 non-SRI patients were divided into DENOS (30 patients) and ZOL group (32 patients) .Results:Hypocalcemia was observed in 26 (33%) patients, and 22 patients developed hypocalcemia during the first treatment course. The incidence of hypocalcemia in the non-SRI patients of DENOS group was higher than that in the ZOL group [20% (6/30) vs 13% (4/32), P=0.028]. The incidence of hypocalcemia in SRI was 89% (16/18). Multivariate logistic regression analysis revealed that endogenous creatinine clearance rate<30 ml/min was significantly associated with hypocalcemia after DENOS administration ( P<0.001). After 1 month of antiresorptive (AR) drug application, the decrease in the serum β-C-terminal cross-linked carboxy-telopeptide of collagen type I concentrations of SRI and non-SRI patients in the DENOS group were significantly higher than that in the ZOL group (68% vs 59% vs 27%, P<0.001). The increase in serum procollagen type Ⅰ N-terminal propeptide concentrations of patients with or without SRI in the DENOS group were significantly higher than that in the ZOL group (34% vs 20% vs 11%, P<0.05). The level of intact parathyroid hormone in each group increased after AR drug treatment. None of the patients developed osteonecrosis of the jaw and renal adverse events, and no statistically significant differences in the overall response rate, complete remission and stringent complete remission rates were found among the groups ( P>0.05), and the median PFS and OS time were not reached ( P>0.05) . Conclusions:In the treatment of MBD, DENOS minimizes nephrotoxicity and has strong AR effect. Hypocalcemia is a common adverse event but is usually mild or moderate and manageable.

Objective To analyze the clinical characteristics,treatment regimens and influencing factors of prognosis of patients with mantle cell lymphoma(MCL).Methods The clinical data of 41 patients with MCL was collected.These patients were initially diagnosed and treated in the Fifth Medical Center of Chinese PLA General Hospital between August 2004 and December 2019.The clinical features,therapeutic efficacy and prognosis-related factors were clarified.Results The median duration of follow-up was 68(1-165)months.The 3-year progression free survival(PFS)and overall survival(OS)were 37.29%and 62.75%respectively.Based on univariate analysis,B symptoms,Eastern Cooperative Oncology Group(ECOG)scores,the mantle cell lymphoma international prognostic index(MIPI),relapse and refractory state and the therapeutic effect were statistically significant for progression free survival.B symptoms,R-chemotherapy and therapeutic effect were statistically significant for overall survival.In multivariate analysis,B symptoms and the MIPI were statistically significant for progression free survival.B symptoms,R-chemotherapy and therapeutic effect were statistically significant for overall survival.There were statistically significant differences in 3-year OS between patients with different MIPI and MIPI-C scores.Conclusion Mantle cell lymphoma mostly occurs in elder males,and is more likely to be detected in late the stage.B symptoms,R-chemotherapy and therapeutic effect are independent prognostic factors for patients with MCL.The MIPI and MIPI-C scores have clinical guidance significance for patient survival.

Objective:This study aimed to evaluate the efficacy and safety of daratumumab as a maintenance treatment after autologous hematopoietic stem cell transplantation (auto-HSCT) in patients with newly diagnosed multiple myeloma (NDMM) .Methods:The clinical data, hematological and renal response, and safety of 15 post-transplant patients with NDMM who had received daratumumab maintenance between May 1, 2022 and June 30, 2023 were retrospectively analyzed.Results:Fifteen patients (11 males and 4 females) with a median age of 58 (41-72) years were included. Thirteen patients did not receive daratumumab during induction therapy and auto-HSCT, 6 patients had renal impairment, and nine patients had high-risk cytogenetics. The median infusion of daratumumab was 12 (6-17) times, and the median duration of maintenance was 6 (1.5-12) months. The treatment efficacy was evaluated in all 15 patients, and daratumumab maintenance therapy increased the rate of stringent complete response from 40% to 60%. The renal response rate and median estimated glomerular filtration rate of six patients with RI-NDMM were also improved. During daratumumab maintenance therapy, the most common hematological grade 3 adverse event (AE) was lymphopenia [4 of 15 patients (26.67%) ], whereas the most common nonhematologic AEs were infusion-related reactions [7 of 15 patients (46.67%) ] and grade 3 pneumonia [5 of 15 patients (33.33%) ]. The five patients with pneumonia were daratumumab naive [5 of 13 patients (38.46%) ], with a median of 8 (6-10) infusions. Among them, the chest computed tomography of three patients showed interstitial infiltrates, and treatment with methylprednisolone was effective. With a median follow-up of 12 months, the 1-year overall survival rate was 93.33%, and only one patient died (which was not related to daratumumab treatment) .Conclusions:Daratumumab was safe and effective as a maintenance agent for post-auto-HSCT patients with NDMM, and AEs were controllable. The most common nonhematologic AE was grade 3 pneumonia, and a less dose-intense maintenance regimen for the first 8 weeks could reduce the incidence of pneumonia.

Objective To analyze the clinical characteristics and recent curative effect of mantle cell lymphoma (MCL) after conventional treatment.Methods Clinical data of 15 MCL patients admitted in the Affiliated Hospital of Academy of Military Medical Sciences between August 2004 and October 2013 were retrospectively analyzed.Results The median age of those patients was 59 and the male to female ratio was 1.5∶1.Fourteen(93%)cases were in Ann-Arbor stages Ⅲ -Ⅳ, 15 cases (100%)primarily with lymph node involvement,7 cases (47%)with bone marrow involvement,4 cases (27%)with gastrointestinal involvement,and 3 cases (20%)with orbit involvement.Less than 40% expression of Ki-67 was observed in 9 cases (60%),while 6 cases were with more than 40% (40%).One case was blastic variant.First-line therapy was CHOP-like regimens,which were combined with rituximab in 8 of the 15 cases.In this study,the median survival time was 12 months (3 -64),and the overal response rate was 80%after induction chemotherapy.The current survival of 7 /9 cases with less than 40% expression of Ki-67 was 8 -64 months,2 /6 cases with more than 40% expression of Ki-67 was 8 and 9 months,respectively.Conclusion MCL mostly occurs in older males.Extranodal invasion is common in MCL as an aggressive tumor.The efficacy of traditional chemotherapy is currently limited.Blastic variant or high expression of Ki-67 is an adverse prognostic indicator.

Objective To investigate the therapeutic effect and adverse effects of the teniposide-based regimen in patients with primary central nervous system lymphoma (PCNSL). Methods Between March 2011 and July 2013, 16 patients with PCNSL were diagnosed and treated. The clinical characteristics, diagnosis,therapy, results and adverse effects were analyzed. Results Totally 16 patients were enrolled and diagnosed as primary central nervous system diffuse large B-cell lymphoma. All patients received teniposide-based regimen chemotherapy and 9 patients received teniposide plus rituximab. The overall response rate was 87.5 % (14/16), including 10 cases of CR and 4 cases of PR. With a median follow-up of 13.5 months, the progression-free survival (PFS) and overall survival (OS) rates of 2 years were 29.9 % and 66.7 %, respectively. The mainly hematological adverse events were neutropenia, including grade 3 in 4 cases (25 %) and grade 4 just in one case. There was one case of treatment related death. Conclusions The response rate of teniposide-based regimen for PCNSL is promising. The 2 year PFS and OS rates are even higher than results of traditional high-dose methotrexate regimen. The teniposide-based regimen is well tolerated, and the adverse events are acceptable.

Objective To analyze the clinical characteristics , diagnosis, therapy and prognosis of new diagnosed pri-mary gastric diffuse large B cell lymphoma ( PGDLBCL) and to discuss the efficacy of rituximab .Methods Between Jan 2005 and May 2012 , twenty-six new-diagnosed PGDLBCL patients were reviewed retrospectively .The clinical characteris-tics, diagnosis, therapy, results and prognostic factors were analyzed .Results There were 14 males and 12 females.Their age ranged from 25 to 82 (median, 50.1) years old.The most common symptom was stomachache .Treatment strategies were chemotherapy alone ( n=9) [ scheduled as cyclophosphamide , doxorubicin , vincristine and prednisone ( CHOP) and CHOP-like] and chemotherapy combined with rituximab (n=17), followed by radiotherapy of the stomach with or without regional nodes .All clinical and pathological features were similar between the two groups .The median follow-up time was 40 months.The overall response rate was 100%(9/9)in CHOP group, including 55.56%(5/9) CR, and 93.75%(15/16) in RCHOP group including 50%(8/16) CR (P>0.05).The total PFS and OS of 5 years were 60.3%and 74.4%respectively.The PFS in CHOP group and RCHOP group was 66.7% and 58.9%, respectively,and the OS was 66.7%and 84.6%, respectively.Although the OS of RCHOP group was much better than that of CHOP group , there was no sta-tistically significant difference.Univariate analysis showed that IPI (P<0.05) and Lugano staging (P<0.05) were inde-pendent factors of survival in patients with PGDLBCL .Conclusion Chemotherapy could be the first-line therapy of PGDL-BCL.The overall survival rate might be increased by adding rituximab to chemotherapy .The Lugano stage and IPI are im-portant prognostic factors .
