ABSTRACT

Objective:To investigate the therapeutic efficacy of chimeric antigen receptor T cell (CAR-T) for treatment of relapsed patients with double expression lymphoma after autologous hematopoietic stem cell transplantation (auto-HSCT).Methods:The treatment process of one patient with double expression diffuse large B-cell lymphoma who received CAR-T immunotherapy after the recurrence of auto-HSCT in Henan Provincial People's Hospital in August, 2017 was retrospectively analyzed, and the related literature was reviewed.Results:A 50-year-old female double expression diffuse large B-cell lymphoma patient received the standard treatment regimen, and then had auto-HSCT based on the BEAM preconditioning regimen. The patient relapsed after 5 months, and finally got sustained remission after chemotherapy regimen containing cladribine for 2 courses of treatment combined with CAR-T therapy. CD20 +-CAR-T cells were detected in this patient for 8 mouths sustainably. Conclusion:For relapsed patients with non-Hodgkin lymphoma after auto-HSCT, reduction remission of the treatment regimen containing cladribine followed by CAR-T sequential regimen may be a better treatment option.

ABSTRACT

Objective@#To explore the expression of CD45 in newly diagnosed multiple myeloma (MM) and its relationship with clinical efficacy and prognosis.@*Methods@#This study retrospectively analyzed expression and distribution of CD45 in 130 cases of newly diagnosed MM, comparing clinical efficacy and prognosis in CD45+/CD45- groups.@*Results@#①The CD45+ group was 33 cases (25.38%) , and CD45- group was 97 cases (74.62%) . ②The objective remission rate (ORR) of CD45+ and CD45-group was 33.33% and 64.95%, respectively. The difference was statistically significant (P=0.002) . For patients in Bortezomib regimen, the ORR of CD45+ and CD45- group was 35.71% and 66.25%, respectively. The difference was statistically significant (P=0.005) . ③The median progress free survival (PFS) of CD45+ group and CD45- group was 29.8 (95%CI 10.0-59.0) months vs 34.5 (95%CI 6.0-69.0) months (χ2=14.59, P<0.001) and the median overall survival (OS) was 32.5 (95%CI 10.0-68.0) months vs 37.6 (95%CI 6.0-78.0) months (χ2=11.42, P=0.001) , respectively. Among the patients in bortezomib regimen, The median PFS and median OS of CD45 + group and CD45- group were 30.3 (95%CI 10.0-59.0) months vs 36.3 (95%CI 6.0-69.0) months (χ2=14.75, P=0.001) and 34.0 (95%CI 10.0-68.0) months vs 39.5 (95%CI 6.0-78.0) months (χ2=10.62, P=0.001) . ④Cox risk regression model analysis showed that serum creatinine≥176.8 μmol/L (HR=5.078, 95%CI 1.744-14.723, P=0.001) , CD45 positive (HR=14.504, 95%CI 0.168-0.42, P=0.001) , LDH≥220 IU/L (HR=1.308, 95%CI 1.16-2.417, P=0.015) were independent risk prognostic factors.@*Conclusion@#CD45 expression is a risk prognostic factor of MM patients. Bortezomib did not improve the poor prognosis of CD45+ MM patients.

ABSTRACT

Objective@#To explore the efficacies of regimens of three-drug induction therapy (ATRA+ATO+anthracyclines) versus two-drug induction therapy (ATRA+ATO) in patients with acute promyelocytic leukemia (APL).@*Methods@#Of 184 patients diagnosed with APL from January 2009 to March 2016, 58 patients underwent three-drug induction therapy, while the rest were treated with two-drug induction therapy. Three-drug induction therapy was of ATRA (20 mg·m-2·d-1, d1-28) + ATO (0.16 mg·kg-1·d-1, d1-28) + Idarubicin (8 mg·m-2·d-1, d3-5) /daunorubicin (40 mg·m-2·d-1, d3-5) , while two-drug induction therapy ATRA+ATO with the same doses and methods as above. Of 184 cases, 69 cases accompanied with WBC counts>10×109/L, 115 cases with WBC counts≤10×109/L at onset.@*Results@#①Short-term efficacy: After one cycle induction therapy, the rates of hematologic remission, genetic remission, molecular remission and induced differentiation syndrome (DS) in three-drug regimen group were 98.3%, 87.9%, 72.4% and 0 respectively, while those in two-drug regimen group were 87.3%, 65.9%, 51.6% and 12.7% respectively. In patients with WBC >10×109/L, DS rate and early mortality in three-drug regimen group were lower than in two-drug regimen group (0 vs 15.6%, 4.2% vs 15.6%, respectively). In patients with WBC≤10×109/L, DS rate in three-drug regimen group was also lower than in two-drug regimen group (0 vs 12.3%) , but there were no statistical differences in terms of relapse and early mortality. ② Long-term efficacy: The relapse rate, overall survival (OS) and disease free survival (DFS) in three-drug regimen group were 0, 98.5%, 96.6% respectively, while those in two-drug regimen group were 8.6%, 86.5% and 84.1% respectively; the advantages of three-drug over two-drug regimen, especially in cases of WBC >10×109/L were observed. ③ Side effects: the incidences of gastrointestinal reaction, liver dysfunction, myocardial damage and headache in three-drug regimen group hardly increased.@*Conclusion@#The efficacies of three-drug induction therapy were superior to two-drug one.

ABSTRACT

Objective To retrospectively review and compare the clinical results of allogeneic peripheral blood stem cell transplantation (allo-PBSCT) from HLA- matched sibling donors mobilized with different regimens. Methods Seventy-one patients with hematological malignant diseases received allo-PBSCT from HLA-matched sibling donors in our department. Among them, 24 received allografts mobilized with G-CSF (group G), and the remaining (47 cases) were mobilized with G-CSF and GM-CSF (group G+ M). CD34+ subsets and T cell subsets in the allografts were analyzed, and the time of hematopoietic reconstitution and the incidence of graft versus host diseases (GVHD) were compared. The adverse effects on the donors after mobilization were also observed. Results The enough targeted CD34+ cells in all donors were harvested by 1-3 aphereses. Ninety-six h after mobilization, WBC counts of the donors were significantly higher in group G than in group G + M [(49. 6± 19. 5) 109/L vs (25.4 ± 10. 4) 109/L, P<0. 05]. Analysis of the CD34+ subsets showed that the percentage of cells with the CD34+/CD38- phenotype was significantly higher in group G + M than in group G [(37. 7 ± 5. 7) % vs (31.4 ± 4. 5) %, P<0. 05]. There was no significant difference in T cells and subsets of grafts. There was no significant difference in the number of total CD34+ cells and CD34+ CD38- cells, and infusion of T cells between two groups. The days required for the recovery of neutrophils and platelets was inversely correlated with the infused CD34+ and CD34+ /CD38- cell number. There was no significant difference in incidence of acute and chronic GVHD between two recipient groups. Seventeen cases and 10 eases among 71 eases died of relapses of primarydiseases, and complications of transplantation such as severe GVHD and infections respectively.Fourteen cases in group G (58.3 %) and 31 cases in group G+ M (66.0 %) survived. The most common adverse events in the donors were bone pain and fever, which mostly occurred 36 h after mobilization and could be relieved by non-steroidal anti-inflammatory drugs. Conclusion Two mobilization regimens showed equivalent clinical results. But the combined regimen of G-CSF and GM-CSF demonstrated a significantly greater mobilization of cells with the CD34+/CD38- phenotype.Meanwhile in allogeneic PBSCT, a greater number of total CD34+ cells and CD34+ CD38- cells infused may be associated with faster hematopoietic reconstitution of recipients.
