OBJECTIVE: To explore the synergistic immunomodulatory mechanism of interferon alpha-1b, interleukin-2 and thalidomide (ITI) regimen on patients with acute myeloid leukemia (AML). METHODS: Sixty eight untreated de novo or relapsed or refractory or maintenance therapy patients with AML admitted in the Affiliated Cancer Hospital of Zhengzhou University and the other 11 medical units from March 2016 to May 2019 were treated with ITI regimen. Peripheral blood specimen per patient was collected into EDTA-K3 anticoagulation vacuum tube before the administration of ITI and 3 months after the treatment; peripheral blood lymphocyte subsets and perforin and Granzyme B expression were analyzed by using flow cytometry; the levels of VEGF, IFN-γ, TNF-α and IL-6 in the plasma were detected by using a cytometric bead array. Thirty-five healthy subjects from the hospital physical examination centre were selected as normal controls. RESULTS: The ratio of CD4 CONCLUSION The ITI regimen can raise the ratio of CD4

OBJECTIVE: To study the efficacy and safety of continuous intravenous infusion of 2-Chlorodeoxyadenosine (2-CdA) combined with high-dose cytarabine (Ara-C) and granulocyte colony-stimulating factor (G-CSF) (CLAG regiem) in the treatment of relapsed/refractory acute myeloid leukemia (AML). METHODS: Fifteen patients with refractory/relapsed AML hospitalized in 5 medical units such as Department of Hematology, the Affiliated Tumor Hospital of Zhengzhou University and received one course of CLAG regimen from June 2014 to August 2019 were analyzed retrospectively (specifically: cladribine 5 mg/M RESULTS: Among the 15 patients with refractory/relapsed AML, 9 males and 6 females, the median age was 35 (13-63) years old. FAB classification: 1 case of M CONCLUSION The CLAG regimen consisting of continuous intravenous infusion of cladribine shows high CR in the treatment of AML patients, but the duration of CR is short, myelosuppression is sever, so that infection control is the key. Allogeneic hematopoietic stem cells transplantation should be performed as soon as possible after CR.

Objective: To explore the effect of combination regimen of interferon alpha-1b, interleukin-2 and thalidomide (ITI regimen) on minimal residual disease (MRD) in patients with acute myeloid leukemia (AML) who were in hematologic remission but MRD-positive. Methods: Eighteen patients (17 from Tumor Hospital of Zhengzhou University and 1 from the First People's Hospital of Pingdingshan City) with AML admitted from July 2016 to June 2018, who were in hematologic remission but MRD-positive were treated with different doses of ITI regimen, and the MRD levels were monitored. Results: Among 18 patients who received a conventional dose of ITI regimen for 1 to 2 months, 7 patients had undetectable MRD, 3 had significant decrease in MRD levels, 3 had elevated MRD level and had hematologic recurrence. Three patients with elevated MRD level received a higher dose of ITI regimen, 2 of them turned to MRD negative and the other 1 patient had decreased MRD level. The total response rate was 72.2%, and the response rate in patients with MRD > 1.0% was 57.1% (4/7) , and that of patients with MRD < 1.0% was 81.8% (9/11) , respectively. Conclusion: The ITI regimen can reduce the MRD level of patient with AML who are in hematologic remission but MRD-positive. The therapeutic effect could be improved by a higher dose administration of ITI regimen, and therapeutic effect may be negatively correlated with MRD level before treatment.

Objective: To explore the clinical efficacy and prognostic factors of first-generation and second-generation tyrosine kinase inhibitors (TKI) based regimen in the treatment of patients with BCR-ABL positive acute lymphoblastic leukemia (ALL) . Methods: Retrospectively analyze the clinical characteristics and prognostic factors of 89 patients with BCR-ABL positive ALL from April 2012 to June 2018 in our hospital, the clinical efficacy of first-generation and second-generation TKI was compared. Results: 60 patients were classified into the first-generation TKI (imatinib) group, and 29 patients were in the second-generation TKI (dasatinib) group. There were no significant differences in gender, age, WBC, hemoglobin concentration, PLT, chromosomal karyotype, the types of fusion genes, allogeneic hematopoietic stem cell transplantation (allo-HSCT) and TKI initiation time between the two groups. The first-generation and second-generation TKI groups, for which the complete remission (CR) rate at the fourth week of induction therapy was 83.3% and 89.7% (P=0.637) , respectively, and the complete molecular remission (CMR) was 48.3%and 58.6% (P=0.363) , respectively, the difference was not statistically significant. The 2-year overall survival (OS) rate of first-generation and second-generation TKI group was 34.9% and 64.0% (χ(2)=4.743, P=0.029) , the 2-year relapse free survival (RFS) rate was 17.2% and 55.0% (χ(2)=8.801, P=0.003) , respectively. Multivariate analysis showed that complete molecular remission (HR=0.281, 95%CI 0.151-0.523, P<0.001) was independent favorable prognostic factor for overall survival (OS) , complete molecular remission (HR=0.209, 95%CI 0.112-0.390, P<0.001) and second-generation TKI (HR=0.318, 95%CI 0.158-0.641, P=0.001) were independent favorable prognostic factors for RFS. Conclusion: For TKI-based regimen of BCR-ABL positive ALL, second-generation TKI is superior to first-generation TKI in OS and RFS time.

OBJECTIVETo investigate the relationship of Ki-67 level with clinical features, immunophenotype, gene mutation, curative efficacy and prognosis in patients with acute lymphoblastic leukemia(ALL).

METHODSFlow cytometry gated at CD45/SSC was used to detect the expression of Ki-67, and the correlation of Ki-67 expression with clinical manifestation, laboratorial indexes, curative efficacy and prognosis was analysed.

RESULTSKi-67 expression level increased in ALL patients, the median expression rate was 29.22%, there was significant difference as compared with the healthy control (P<0.01). In adult ALL, the median expression rate of Ki-67 in the high-risk group was 31.49%, and the difference was statistically significant as compared with the low-risk group (P<0.05). In children ALL, the median expression rate of Ki-67 in high-risk group was 42.28%, and the difference was statistically significant (P<0.05). The results of unvariate analysis showed that the age, WBC count at newly diagnosed and extramedullary invasion were adverse factors affecting OS and DFS; the results of multivariate analysis showed that age and extramedullary invasion were independent risk factors for OS and DFS in patients.

CONCLUSIONAge≥14 years old, intramedullary invasion are the poor factors for prognosis; the Ki-67 level is not an independent factor for the prognosis of patients.

Objective: To explore the clinical features of patients with synchronous lymphoma and carcinoma. Methods: The clinical data of 17 patients with Synchronous lymphoma and carcinoma from February 2012 to October 2017 were analyzed retrospectively. Results: Among 17 patients of lymphoma, 1 case HL, 2 cases B-NHL, 6 cases MZBL, 3 cases DLBCL, 1 case mantle cell lymphoma (MCL) , 3 cases NK/T- cell lymphoma, 1 case anaplastic large cell lymphoma(ALCL). In terms of 17 patients with carcinoma, 3 cases esophageal carcinoma, 3 cases gastric carcinoma, 2 cases colorectal carcinoma, 7 cases thyroid carcinoma, 1 case hepatocellular carcinoma and lung cancer. Up to 15 patients received operation, and some of them combined with chemotherapy, radiotherapy and autologous transplant. Follow-up analysis showed that 3 cases was undergoing treatment, 2 cases lost follow-up, 4 cases died, 3 cases achieved CR, 3 cases remained to be at SD, and 2 cases assessed for progression or recurrence. Conclusion: The relationship between lymphoma and carcinoma was under discussion, patients with synchronous lymphoma and carcinoma were not unusual. We herein should raise awareness to avoid misdiagnosis.
