Objective: To explore the stem cell collection rate and efficacy and safety of patients aged 70 and below with newly diagnosed multiple myeloma (MM) treated with the VRD (bortezomib, lenalidomide and dexamethasone) regimen followed by autologous stem cell transplantation (ASCT). Methods: Retrospective case series study. The clinical data of 123 patients with newly diagnosed MM from August 1, 2018, to June 30, 2020, at the First Affiliated Hospital of Soochow University and Suzhou Hopes Hematology Hospital, who were eligible for VRD regimen sequential ASCT, were collected. The clinical characteristics, efficacy after induction therapy, mobilization regimen of autologous stem cells, autologous stem cell collection rate, and side effects and efficacy of ASCT were retrospectively analyzed. Results: Of the 123 patients, 67 were males. The median patient age was 56 (range: 31-70) years. Patients with IgG, IgA, IgD, and light-chain types accounted for 47.2% (58/123), 23.6% (29/123), 3.2% (4/123), and 26.0% (32/123) of patients, respectively. In addition, 25.2% (31/123) of patients had renal insufficiency (creatinine clearance rate<40 ml/min). Patients with Revised-International Staging System (R-ISS) Ⅲ accounted for 18.2% (22/121) of patients. After induction therapy, the rates of partial response and above, very-good partial response (VGPR) and above, and complete response (CR)+stringent CR were 82.1% (101/123), 75.6% (93/123), and 45.5% (56/123), respectively. Overall, 90.3% (84/93) of patients were mobilized with cyclophosphamide+granulocyte colony-stimulating factor (G-CSF) and 8 patients with G-CSF or G-CSF+plerixafor due to creatinine clearance rate<30 ml/min and one of them was mobilized with DECP (cisplatin, etoposide, cyclophosphamide and dexamethasone)+G-CSF for progressive disease. The rate of autologous stem cell collection (CD34⁺cells≥2×10⁶/kg) after four courses of VRD regimen was 89.1% (82/92), and the rate of collection (CD34⁺cells≥5×10⁶/kg) was 56.5% (52/92). Seventy-seven patients treated with the VRD regimen sequential ASCT. All patients had grade 4 neutropenia and thrombocytopenia. Among the nonhematologic adverse events during ASCT, the highest incidence was observed for gastrointestinal reactions (76.6%, 59/77), followed by oral mucositis (46.8%, 36/77), elevated aminotransferases (44.2%, 34/77), fever (37.7%, 29/77), infection (16.9%, 13/77) and heart-related adverse events (11.7%, 9/77). Among the adverse events, grade 3 adverse events included nausea (6.5%, 5/77), oral mucositis (5.2%, 4/77), vomiting (3.9%, 3/77), infection (2.6%, 2/77), elevated blood pressure after infusion (2.6%, 2/77), elevated alanine transaminase (1.3%, 1/77), and perianal mucositis (1.3%, 1/77); there were no grade 4 or above nonhematologic adverse events. The proportion of patients who achieved VGPR and above after VRD sequential ASCT was 100% (75/75), and the proportion of patients who were minimal residual disease-negative (<10^-4 level) was 82.7% (62/75). Conclusion: In patients aged 70 and below with newly diagnosed MM treated with VRD induction therapy, the collection rate of autologous stem cells was good, and good efficacy and tolerability were noted after follow-up ASCT.

Objective: To evaluate the advantages and safety of Plerixafor in combination with granulocyte colony-stimulating factor (G-CSF) in autologous hematopoietic stem cell mobilization of lymphoma. Methods: Lymphoma patients who received autologous hematopoietic stem cell mobilization with Plerixafor in combination with G-CSF or G-CSF alone were obtained. The clinical data, the success rate of stem cell collection, hematopoietic reconstitution, and treatment-related adverse reactions between the two groups were evaluated retrospectively. Results: A total of 184 lymphoma patients were included in this analysis, including 115 cases of diffuse large B-cell lymphoma (62.5%) , 16 cases of classical Hodgkin's lymphoma (8.7%) , 11 cases of follicular non-Hodgkin's lymphoma (6.0%) , 10 cases of angioimmunoblastic T-cell lymphoma (5.4%) , 6 cases of mantle cell lymphoma (3.3%) , and 6 cases of anaplastic large cell lymphoma (3.3%) , 6 cases of NK/T-cell lymphoma (3.3%) , 4 cases of Burkitt's lymphoma (2.2%) , 8 cases of other types of B-cell lymphoma (4.3%) , and 2 cases of other types of T-cell lymphoma (1.1%) ; 31 patients had received radiotherapy (16.8%) . The patients in the two groups were recruited with Plerixafor in combination with G-CSF or G-CSF alone. The baseline clinical characteristics of the two groups were basically similar. The patients in the Plerixafor in combination with the G-CSF mobilization group were older, and the number of recurrences and third-line chemotherapy was higher. 100 patients were mobilized with G-CSF alone. The success rate of the collection was 74.0% for one day and 89.0% for two days. 84 patients in the group of Plerixafor combined with G-CSF were recruited successfully with 85.7% for one day and 97.6% for two days. The success rate of mobilization in the group of Plerixafor combined with G-CSF was substantially higher than that in the group of G-CSF alone (P=0.023) . The median number of CD34(+) cells obtained in the mobilization group of Plerixafor combined with G-CSF was 3.9×10(6)/kg. The median number of CD34(+) cells obtained in the G-CSF Mobilization group alone was 3.2×10(6)/kg. The number of CD34(+) cells collected by Plerixafor combined with G-CSF was considerably higher than that in G-CSF alone (P=0.001) . The prevalent adverse reactions in the group of Plerixafor combined with G-CSF were grade 1-2 gastrointestinal reactions (31.2%) and local skin redness (2.4%) . Conclusion: The success rate of autologous hematopoietic stem cell mobilization in lymphoma patients treated with Plerixafor combined with G-CSF is significantly high. The success rate of collection and the absolute count of CD34(+) stem cells were substantially higher than those in the group treated with G-CSF alone. Even in older patients, second-line collection, recurrence, or multiple chemotherapies, the combined mobilization method also has a high success rate of mobilization.

OBJECTIVE: To evaluate the efficacy and safety of etoposide combined with cyclophosphamide (EC) regimen for mobilization of autologous peripheral blood stem cells (APBSCs) in patients with multiple myeloma (MM). METHODS: The clinical data of 48 MM patients who received APBSC transplantation (APBSCT) in Department of Hematology of the First Affiliated Hospital of Nanchang University from January 2015 to October 2021 were retrospectively analyzed. The mobilization success rate and mobilization optimal rate of EC regimen were counted, and its effect on transplant efficacy, adverse reactions, hematopoietic reconstitution after transplantation, and survival time of MM patients were analyzed. RESULTS: APBSCs were collected on day 14 (10-19) after EC administration. The median of collected CD34⁺ cells was 6.82 (1.27-22.57)×10⁶/kg, and the median number of apheresis session was 2 (1-4). The mobilization success rate (collecting CD34⁺ cells≥2×10⁶ cells/kg after completion of apheresis) was 98% (47/48), and mobilization optimal rate (collecting CD34⁺ cells≥5×10⁶ cells/kg after completion of apheresis) was 71% (34/48). The depth of remission were improved after APBSCT, and the complete remission (CR) rate increased from 45.8% before transplantation to 87.5% after transplantation (P <0.01). There was no transplant-related death, no blood transfusion during mobilization, and no mucositis occurred in the patients. The most common complication was neutropenia, with an incidence of 75.0% (36/48). After transplantation, all the patients successfully achieved hematopoietic reconstitution. The median time to neutrophil engraftment was 10 (9-26) days, and median time to platelet engraftment was 10 (8-33) days. By the end of follow-up, both the median progression-free survival (PFS) and overall survival (OS) time were not reached. The 5-year estimated PFS rate and OS rate was 53.8% and 82.4%, respectively. CONCLUSION The EC regimen for mobilization of APBSC has a high acquisition success rate and controllable adverse reactions, which can be an effective and safe mobilization regimen in MM patients.

Objective: To evaluate the efficacy and safety of autologous hematopoietic stem cell transplantation (auto-HSCT) in elderly patients (≥65 years old) with multiple myeloma (MM) . Methods: From June 1, 2006 to July 31, 2020, 22 MM patients (≥65 years old) who were diagnosed in the First Affiliated Hospital, Sun Yat-sen University and received novel drug induction followed by auto-HSCT were analyzed retrospectively. These patients were evaluated for important organ functions before transplantation, and the International Myeloma Working Group frail score was used in 2016 to screen out transplant-eligible patients. Results: The median (interquartile range, IQR) age at the time of transplantation of the 22 patients was 66.75 (IQR 4.50) years. A total of 20 patients received stem cell mobilization. The median number of mononuclear cells collected was 4.53×10(8)/kg, that of CD34(+) cells was 3.37×10(6)/kg, and the median number of apheresis procedures performed was 2. After stem cell transfusion, the median time of neutrophil implantation was 11 days, that of platelet implantation was 13 days, and the treatment-related mortality was 0 at 100 days after transplantation. The median follow-up was 48.7 months. The median time to progression time was not reached, and the median overall survival time was 111.8 months. Conclusion: Auto-HSCT is a safe and effective treatment for selected elderly patients of 65 years or older with MM.

OBJECTIVE: To investigate the application effect of sequential autologous hematopoietic stem cell transplantation (Auto-HSCT) with lenalidomide, bortezomib and dexamethasone (RVD) in the treatment of multiple myeloma (MM) evaluated by propensity score matching. METHODS: The clinical data of 49 MM patients treated with RVD scheme and followed-up for 36 months in the hospital from January 2015 to January 2021 were retrospectively analyzed and included in the control group, the clinical data of 54 MM patients who received RVD scheme and sequential Auto-HSCT scheme and completed 36 months of follow-up in the hospital during the same period were collected and included in the observation group. PSM method (1∶1, caliper value=0.01) was used to match the control group with the observation group based on baseline data and laboratory indexes, covariate equilibrium samples were obtained between groups (40 cases in each group). The clinical efficacy of patients in the two groups after 18 weeks of treatment was compared; the incidence of toxic and side effects during treatment of patients in the two groups was compared; the survival of patients in the two groups was compared after 36 months of follow-up. RESULTS: The ORR and DCR in the observation group were higher than those in the control group, the difference was statistically significant (P<0.05). Compared the incidence of fatigue, rash, thrombocytopenia, anemia and nausea of patients in the two groups, there was no statistical significant difference (P>0.05). After 36 months of follow-up (no loss during follow-up), 4 cases died from illness in the observation group, with a survival rate of 90% and an average survival time of 35.61 (95% CI: 35541-35.685) months, 10 cases died from illness in the control group, with a survival rate of 75% and an average survival time of 34.70 (95% CI: 34.559-34.832) months, the survival rate of the observation group was higher than that of the control group, the difference was statistically significant (P<0.05). CONCLUSION Sequential Auto-HSCT with RVD regimen in the treatment of MM can improve the short-term efficacy and increase the survival rate of patients, which will not increase toxic and side effects and has high safety.

BACKGROUND: The impacts of previous cardio-cerebrovascular disease (pre-CCVD) on the outcomes of hematopoietic cell transplantation (HCT) are not well described. Patients with pre-CCVD may often be poor candidates for HCT. This study aimed to investigate the impact of pre-CCVD on transplant outcomes. METHODS: A retrospective study was conducted between patients with and without pre-CCVD who consecutively received allogeneic or autologous HCT between November 2013 and January 2020 with a matching of age and disease status. The cardiovascular complications and HCT outcomes of the two groups were evaluated and compared. The primary endpoints were post-transplant cardio-cerebrovascular disease (post-CCVD) and non-relapse mortality (NRM). We used a multivariable Cox proportional hazard model and the Fine-Gray competing risk regressions for analyses to estimate the hazard ratios (HRs). RESULTS: The outcomes of 23 HCT recipients with pre-CCVD were compared with those of 107 patients in the control group. No significant differences were noted in terms of engraftment, overall survival (OS) (67.00% vs. 67.90%, P = 0.983), or relapse (29.78% vs. 28.26%, P = 0.561) between the pre-CCVD group and the control group. The cumulative incidences of 2-year NRM were similar between patients with pre-CCVD and the controls (14.68% vs. 17.08%, P = 0.670). However, pre-CCVD was associated with an increased incidence of post-CCVD (HR: 12.50, 95% confidence interval [CI]: 3.88-40.30, P < 0.001), which was an independent risk factor for increased NRM (HR: 10.29, 95% CI: 3.84-27.62, P < 0.001) and inferior OS (HR: 10.29, 95% CI: 3.84-27.62, P < 0.001). CONCLUSIONS These findings suggest that the existence of pre-CCVD before transplantation might not result in increased mortality directly but superpose the toxicity of the transplantation procedure, leading to a risk of post-CCVD. Post-CCVD was a powerful predictor for high NRM and inferior OS. Further risk stratification of pre-CCVD is needed to reduce NRM in various transplantation settings.

PURPOSE: We report our initial experience with transurethral injection of autologous adipose-derived regenerative cells (ADRCs) for the treatment of urinary incontinence after radical prostatectomy. MATERIALS AND METHODS: After providing written informed consent, six men with persistent urinary incontinence after radical prostatectomy were enrolled in the study. Under general anesthesia, about 50 mL of adipose tissue was obtained from the patients by liposuction. ADRCs were obtained by separation with centrifugation using the Celution cell-processing device. A mixture of ADRCs and adipose tissue were transurethrally injected into the submucosal space of the membranous urethra. Functional and anatomical improvement was assessed using a 24-h pad test, validated patient questionnaire, urethral pressure profile, and magnetic resonance imaging (MRI) during 12-week follow-up. RESULTS: Urine leakage volume was improved with time in all patients in the 24-h pad test, with the exemption of temporal deterioration at the first 2 weeks post-injection in 2 patients. Subjective symptoms and quality of life assessed on the basis of questionnaire results showed similar improvement. The mean maximum urethral closing pressure increased from 44.0 to 63.5 cm H2O at 12 weeks after injection. MRI showed an increase in functional urethral length (from 6.1 to 8.3 mm) between the lower rim of the pubic bone and the bladder neck. Adverse events, such as pelvic pain, inflammation, or de novo urgency, were not observed in any case during follow-up. CONCLUSION: This study demonstrated that transurethral injection of autologous ADRCs can be a safe and effective treatment modality for postprostatectomy incontinence.

BACKGROUND/AIMS: The purpose of this study was to determine the correlations between inflammatory factors-including absolute lymphocyte count, lactate dehydrogenase, beta2-microglobulin, albumin, C-reactive protein, and ferritin-and the prognosis for survival in patients with multiple myeloma (MM) treated with induction chemotherapy containing thalidomide and who underwent autologous stem cell transplantation (ASCT). METHODS: Data from patients at 13 university hospitals in South Korea were collected retrospectively between December 2005 and May 2013. RESULTS: The median age of the 232 patients was 57 years (range, 33 to 77) and the male to female ratio was 1.09:1. In the multivariate analysis, fewer than two combined abnormal inflammatory factors was the only independent prognostic factor for superior progression-free survival (relative risk [RR], 0.618; 95% confidence interval [CI], 0.409 to 0.933; p = 0.022), and platelet count > 100 x 109/L and fewer than two combined abnormal inflammatory factors were independent prognostic factors for superior overall survival (RR, 4.739; 95% CI, 1.897 to 11.839; p = 0.001 and RR, 0.263; 95% CI, 0.113 to 0.612; p = 0.002, respectively). CONCLUSIONS: Patients with two or more than two combined inflammatory factors who were treated with thalidomide induction chemotherapy and who underwent ASCT showed significantly shorter survival compared to those with fewer than two combined inflammatory factors. These results could be helpful for predicting prognosis in patients with MM.
