Objective To observe the efficacy of liposomal doxorubicin combined with cyclophosphamide, vincristine and prednisone in the treatment of refractory Non-Hodgkin’s lymphoma.Methods Liposomal doxorubicin (40mg/m2) was given by intravenous drip in the 1st day. Cyclophosphamide (750mg/m2) was given by intravenous injection in the 1st day. Vincristine (2mg) was given by intravenous injection in the 1st day. Prednisone (100mg/m2) was given orally from the 1st to the 5th day. A cycle was repeated every 3 to 4 weeks. Every patient took at least 2 cycles of the regimen.Results A total of 13 patients were assessed in the group. Among them, 7 were completely release (53.8), 4 were partially release (30.67) and 2 remained the same (15.35). The B symptom of 7 patients in the 9 with that disappeared, and that of the other 2 patients was improved obviously. The most common adverse effects were slight gastrointestinal reactions and the grade Ⅲ bone marrow suppression in a few patients. Conclusion The regimen of liposomal doxorubicin combined with cyclophosphamide, vincristine and prednisone is effective in the treatment of refractory Non-Hodgkin’s lymphoma with tolerable toxicity. It may be a salvage chemotherapeutic regimen deserving further study.

Castleman disease (CD) is an uncommon non-clonal lymphoproliferative disorder with unknown etiology.No standard therapy is recommended for relapsed/refractory CD patients,thus requiring development of novel experimental approaches.Our cohort of three adult patients with multicentric CD (MCD) were treated with refractory to traditional chemotherapy ienalidomide-containing regimens (10-25 mg lenalidomide perorally administered on days 1-21 in 28-day cycle) as second-to fourth-line treatment.Partial remission was achieved in first plasma-cell CD patient,who relapsed seven months after autologous hematopoietic stem cell transplantation and then failed to respond to four cycles of chemotherapy.Partial remission was obtained in second patient with CD and polyneuropathy,organomegaly,endocrinopathy,monoclonal gammopathy,and skin changes syndrome.Third case showed complete remission with complete disappearance of pleural effusion and ascites and normalization of platelet count.To conclude,encouraging clinical responses were achieved in cohort of three patients with lenalidomide-based regimen,though long-term efficacy remains to be observed.We propose further investigation of therapeutic potential of this drug in treating MCD.

A CALLG2008 protocol was developed by the Chinese Acute Lymphoblastic Leukemia Cooperative Group for adult acute lymphoblastic leukemia (ALL).We retrospectively analyzed 153 newly diagnosed adult patients with Philadelphia chromosome (Ph)-positive ALL enrolled into imatinib (400 mg/d) plus CALLG2008 regimen between 2009 and 2015.The median age was 40 years (range,18-68 years),with 81 (52.3％) males.The overall hematologic complete remission (CR) rate was 96.7％ after induction.With a median follow-up of 24.2 months,the estimated 3-year overall survival (OS) and event-free survival (EFS) rates were 49.5％ (95％ confidence interval (CI):38.5％-59.5％) and 49.2％ (95％ CI:38.3％-59.2％),respectively.Fifty-eight (36 with haploidentical donor) patients underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) in first CR.Among the patients in CR1 after induction,both the 3-year OS and EFS were significantly better in the allo-HSCT group than in the without allo-HSCT group (73.2％,95％ CI:58.3％-83.5％ vs.22.2％,95％ CI:8.7％-39.6％ and 66.5％,95％ CI:50.7％-78.2％ vs.16.1％,95％ CI:5.1％-32.7％,respectively).Multivariate analysis showed that allo-HSCT and achievement of major molecular response were associated with favorable OS or EFS independently.Interestingly,in the allo-HSCT cohort,the donor type (haploidentical versus matched donors) had no significant impact on EFS or OS.All these results suggested that imatinib plus CALLG2008 was an effective protocol for Ph-positive ALL.Haploidentical donors can also be a reasonable alternative expedient donor pool.

Objective: To study the clinical features, therapeutic effects, prognostic factors of 140 patents with mantle cell lymphoma (MCL). Methods: Clinical data of 140 MCL patients admitted from June 2009 to January 2016 in our hospital were retrospectively analyzed. Results: The median age of 140 patients was 59 years with a ratio of 6∶1 for men and women. There were 134 cases (95.7%) in Ann-Arbor stage Ⅲ-Ⅳ, 37 cases (26.4%) with B symptoms, 61 cases (43.6%) with bone marrow involvement and 38 cases (27.1%) with enlarged spleen. The overall response rate (ORR), 3-year survival rate and progression-free survival rate in the treatment group with rituximab were 87.1%, 68.1% and 59.5% respectively, which were significantly higher than those in the rituximab-free treatment group (66.6%, 51.5% and 31.7%, respectively). The difference was statistically significant (all P<0.05). Among patients treated with rituximab, the complete remission rates (70.8% and 77.8%) of R-HyperCVAD/MA and VcR-CAP regimens were higher than those of R-CHOP regimen (39.0%, both P<0.05). However, there was no significant difference in the overall response rate, overall survival rate and progression-free survival rate (all P>0.05). Univariate analysis showed that age, Ki-67 index, B symptoms, bone marrow invasion, platelet count, LDH, β₂-MG and MIPI scores were associated with overall survival (all P<0.05). Multivariate analysis showed that age (HR=4.940, 95% CI: 2.347 to 10.397), B symptom (HR=2.900, 95% CI: 1.517-5.544), β₂-MG (HR=2.945, 95% CI: 1.656-5.238), Ki-67 index (HR=4.915, 95% CI: 2.554-9.456) and treatment with rituximab-containing regimen (HR=2.450, 95% CI: 1.352-4.440) were independent factors for OS. Conclusions Most patients with MCL were older adults and usually had bone marrow involvement and spleen involvement. Rituximab combined with chemotherapy (especially R-HyprCVAD/MA and VcR-CAP) had better clinical efficacy than conventional chemotherapy.

This study aimed to investigate the prevalence, clinical characteristics, and prognostic impact of 1p32.3 deletion in patients with newly diagnosed multiple myeloma (MM). A retrospective analysis was conducted on 411 patients with newly diagnosed MM; among which, 270 received bortezomib-based therapies, and 141 received thalidomide-based therapies. Fluorescence in situ hybridization (FISH) was performed to detect six cytogenetic abnormalities, namely, del(1p32.3), gain(1q21), del(17p13), del(13q14), t(4;14), and t(11;14). Results showed that 8.3% of patients with MM were detected with del(1p32.3) and had significantly more bone marrow plasma cells (P = 0.025), higher β2-microglobulin levels (P = 0.036), and higher lactate dehydrogenase levels (P = 0.042) than those without del(1p32.3). Univariate analysis showed that patients with del(1p32.3) under thalidomide-based therapies (median PFS 11.6 vs. 31.2 months, P = 0.002; median OS 16.8 vs. 45.9 months, P < 0.001) were strongly associated with short progression-free survival (PFS) (P = 0.002) and overall survival (OS) (P < 0.001). Multivariate analysis revealed that del(1p32.3) remained a powerful independent factor with worse PFS (P = 0.006) and OS (P = 0.016) for patients under thalidomide-based treatments. Patients with del(1p32.3) under bortezomib-based treatments tended to have short PFS and OS. In conclusion, del(1p32.3) is associated with short PFS and OS in patients with MM who received thalidomide- or bortezomib-based treatments.
