Comparison of clinical efficacy between first-generation and second-generation tyrosine kinase inhibitors based regimen in the treatment of patients with BCR-ABL positive acute lymphoblastic leukemia / 中华血液学杂志

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% (χ2=4.743, P=0.029) , the 2-year relapse free survival (RFS) rate was 17.2% and 55.0% (χ2=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.

Clinical efficacy and safety of L-asparaginase combined with GDP regimen in treat-ment of patients with extranodal NK/T-cell lymphoma / 中国肿瘤临床

Objective:To evaluate the clinical efficacy and safety of L-asparaginase (L-ASP) combined with GDP regimen in initial treat-ment of patients with extranodal NK/T-cell lymphoma (ENKL). Methods:A total of 39 patients preliminarily diagnosed with nasal NK/T-cell lymphoma in Zhengzhou University Affiliated Cancer Hospital were retrospectively analyzed from January 2012 to January 2014. All patients received L-ASP combined with GDP chemotherapy. The efficacy of the treatment was observed (L-ASP 6000/m2, qod × 8;gemcitabine 1000 mg/m2, d1, 8;cisplatinum 90 mg/m2, d1;dexamethasone 10 mg, d1-4) every 21 days for one cycle. The efficacy and toxicity of the regimen were evaluated after therapy. Results:Of the 39 patients who received median six-cycle L-GDP regimen treat-ment, 24 achieved complete response, 7 had partial response, 6 had stable disease, and 2 had progressive disease. The rates of overall response (CR+PR), 2-year progression-free survival, and overall survival were 79.5%(31/39), 71.8%(28/39), and 87.2%(34/39), respec-tively. The primary side effects included gastrointestinal reaction, bone marrow suppression, and increased PT and APPT levels. All pa-tients tolerated and completed the therapy without termination of treatment and death. Conclusion:L-ASP combined with GDP regi-men is effective and safe and thus can be used for patients with ENKL.

A report of two cases with Richter's syndrome and literature review / 白血病·淋巴瘤

Objective To explore the epidemiology, clinical and pathological characteristics,treatment and prognosis of Richter's syndrome (RS). Methods The clinical and laboratory feature,treatment, prognosis of two cases were reported, and the related literature was reviewed. Results The major symptom of two cases suffered with enlarged lymph nodes, and pathological examination indicated a diffuse large B cell lymphoma. A large number of mature small lymphocytes were found in peripheral blood and bone marrow, and the immune phenotype was consistent with chronic lymphocytic leukemia. CHOP regiment was used on two cases. One obtained complete remission, and the other cases partial remission. Conclusion RS may occur at early stage after CLL diagnosis. In some cases, the diagnosis of RS and CLL are concomitant.Prognosis of some patients of RS is unfavourable. It was important to take biopsy at early stage.

ABVD chemotherapy scheme at day 1 and 8 for treatment of primary Hodgkin's lymphomas / 中华内科杂志

Objective To explore the effect of adriamycin, bleomyein, vincristine and dacarbazinum (ABVD) chemotherapy scheme executed at day I and day 8 for primary Hodgkin's lymphomas (HL). Methods 62 patients with primary HL in stages Ⅱ-Ⅳ treated in our department from October 2005 to October 2006 were divided into group A and B at random with 31 patients in each group. The patients in group A received ABVD chemotherapy scheme executed at day 1 and day 8 for 6-8 cycles. The patients in group B received ABVD chemotherapy scheme executed at day 1 and day 15 for 6-8 cycles. The patients of the groups received radiotherapy by the same doctor after chemotherapy according to the patients condition and the radiotherapy regimens were not affected by the grouping. Results The complete remission rate (CR)in group A after chemotherapy was 90. 3% (28/31);the one-year and two-year disease free survival (DFS) rates were 87. 1% (27/31) and 80.0% (20/25)respectively. The CR rate in group B after chemotherapy was 83.9% (26/31);the one-year and two-year DFS rates were 80. 6% (25/31)and 72. 0% (18/25) respectively. The discrepancy of CR rates and the one-year and two-year DFS rates between the two groups was not significant (P>0.05). The incidences of therapeutic side effecte such as myocardial iscnemia grade Ⅲ-Ⅳ liver function impair-ment,pulmonary fibrosis and serious marrow inhibition between the two groups were not significant too (P > 0.05). Average chemotherapy period for the patients in group A was 159 days; it was 69 days shorter than that in group B. Conclusion The CR rate,1-year DFS rate and 2-year DFS rate of ABVD chemotherapy scheme executed at day 1 and 8 are similar to those of ABVD chemotherapy scheme executed at day Ⅰ and 15 for primary HL in stages Ⅱ-Ⅳ. The side-effects of chemoterapy between group A and B are similar too. The chemotherapy period in group A is shortened significantly.

Primary Hodgkin disease of the supermaxilla: a case report and review of the literatures / 白血病·淋巴瘤

Objective To intensify the diagnosis and treatment of primary osseous Hodgkin disease (HD) and reinforce the impression of its features of pathology and imaging. Methods The clinical manifestation, laboratory examination, treatment and outcome of a patient with primary Hodgkin disease of the supermaxilla were first reported and the pertinent literatures were reviewed. Results Pain of the right supermaxilla was the first clinicM symptom. Plain X-rays showed mixed osteolytic and partially osteosclerotie lesions in the right supermaxiUa. The tumor was removed and the pathohistology was HD lymphocyte-depletion. The clinical diagnosis was primary HD of the supermaxilla (Stage Ⅰ ). The case was treated with ABVD regimen and no obviously adverse reaction appeared. Conclusion Primary osseous HD rarely presents as a malignant bone lymphoma and is easily misdiagnoed. Pathological and immunohistologic studies can be useful to confirm the diagnosis of primary osseous HD. Early diagnosis and the differentiation from other disease should be performed and the prognosis of the present-day chemotherapy regimen appears good.
