Non-Hodgkin lymphoma (NHL) is a common lymphoid hematological malignancy, the treatment and prognosis of NHL have always been the focus of clinical attention. Chemotherapy is the main first-line treatment, but there is still no effective treatment for patients with poor response to chemotherapy, recurrence or progression within a short period of time after treatment, and new and effective drugs need to be developed clinically. As the only clinically validated oral selective inhibitor of nuclear export (SINE), Selinexor has been approved for the treatment of relapsed/refractory diffuse large B-cell lymphoma and multiple myeloma, clinical attempts are being made to apply it to the treatment of other hematological malignancies.This article reviews the anti-tumor mechanism of Selinexor and the latest research progress in its application in NHL, and provides ideas for a more diverse, standardized and effective applications of Selinexor in NHL.

OBJECTIVE: To explore the intervention effect of recombinant human interleukin-11 (rhIL-11) and recombinant human granulocyte-colony stimulating factor (rhG-CSF) on the duration and severity of agranulocytosis in patients with hematological malignancies after chemotherapy, and to analyze the influencing factors. METHODS: The data of hematological malignancy patients treated with rhIL-11 and rhG-CSF after chemotherapy in the hematology department of The First Hospital of Lanzhou University from July 2017 to July 2020 were collected retrospectively. The duration and differences of agranulocytosis in differeent groups were compared by univariate analysis, and the influencing factors of agranulocytosis duration were further analyzed by multiple regression analysis. RESULTS: The duration of agranulocytosis in 97 patients was 6.47±2.93 days. The results of univariate analysis showed that there were no statistical differences in the duration of agranulocytosis among patients with different sex, age, height, weight, body surface area, body mass index (BMI), dose of rhG-CSF, dose of rhIL-11, spontaneous bleeding after administration of rhG-CSF and rhIL-11, and the duration of agranulocytosis in patients with different red blood cell count (RBC), hemoglobin(HGB) level, platelet count (PLT) and absolute neutrophil count (ANC), before administration of rhG-CSF and rhIL-11. There were significant differences in agranulocytosis time among patients with different disease types, chemotherapy cycle, fever after rhG-CSF and rhIL-11 administration, and different white blood cell count (WBC) baseline level before rhG-CSF and rhIL-11 administration (P＜0.05). Compared with patients with acute lymphoblastic leukemia (ALL) and non-Hodgkin lymphoma (NHL), patients with acute myeloid leukemia (AML) had the longest duration of agranulocytosis, which was 7.07±3.05 d. Compared with patients with chemotherapy cycles of 4－6 and ≥7, patients with total chemotherapy cycle of 1－3 had the shortest duration of agranulocytosis, which was 5.25±2.48 d. Compared with patients without fever, patients with fever within 1 day after administration of cytokines and patients with fever within 2-5 days after administration of cytokines, the duration of agranulocytosis was the longest in patients with fever 6 days after administration of cytokines, which was 8.85±2.85 d. Compared with patients with WBC baseline <1.0×10⁹/L, (1.0－1.9)×10⁹/L and (2.0－3.9)×10⁹/L, patients with WBC baseline ≥4.0×10⁹/L had the shortest duration of agranulocytosis, which was 4.50±2.56 d. Multiple linear regression analysis showed that chemotherapy cycle, different fever after administration of rhG-CSF and rhIL-11, diagnosis of ALL and NHL, and WBC baseline level before administration of rhG-CSF and rhIL-11 were the influencing factors of the duration of agranulocytosis (P＜0.001). CONCLUSION The risk of prolonged agranulocytosis is higher in patients diagnosed with AML, with more chemotherapy cycles, lower WBC baseline before cytokines administration and fever later after cytokines administration, which should be paid more attention to.

Abnormal cell apoptosis is closely related to the occurrence of hematologic tumors, B-cell lymphoma-2 (BCL-2), as a key anti-apoptotic protein in intrinsic programmed cell death, has become a hot spot in the treatment of hematologic tumors in recent years. Venetoclax is an oral small-molecule selective BCL-2 inhibitor approved by the Food and Drug Administration (FDA） for the treatment of chronic lymphocytic leukemia (CLL) patients or small lymphocytic lymphoma (SLL) patients and for the treatment of elderly acute myeloid leukemia (AML) patients that is not suitable for aggressive chemotherapy. In addition, it also showed a promising clinical application in treatment of non-Hodgkin's lymphoma (NHL) patients, which is a new expansion of the clinical indications for venetoclax. In this review, the role of BCL-2 protein family played in the regulation of NHL cell apoptosis, the development of BCL-2 inhibitors and the recent research progress of venetoclax in the treatment of NHL are reviewed.

BACKGROUND: Bendamustine was approved in China on May 26th, 2019 by the National Medical Product Administration for the treatment of indolent B-cell non-Hodgkin lymphoma (NHL). The current study was the registration trial and the first reported evaluation of the efficacy, safety, and pharmacokinetics of bendamustine in Chinese adult patients with indolent B-cell NHL following relapse after chemotherapy and rituximab treatment. METHODS: This was a prospective, multicenter, open-label, single-arm, phase 3 study (NCT01596621; C18083/3076) with a 2-year follow-up period. Eligible patients received bendamustine hydrochloride 120 mg/m2 infused intravenously on days 1 and 2 of each 21-day treatment cycle for at least six planned cycles (and up to eight cycles). The primary endpoint was the overall response rate (ORR); and secondary endpoints were duration of response (DoR), progression-free survival (PFS), safety, and pharmacokinetics. Patients were classified according to their best overall response after initiation of therapy. Proportions of patients in each response category (complete response [CR], partial response [PR], stable disease, or progressive disease) were summarized along with a two-sided binomial exact 95% confidence intervals (CIs) for the ORR. RESULTS: A total of 102 patients were enrolled from 20 centers between August 6th, 2012, and June 18th, 2015. At the time of the primary analysis, the ORR was 73% (95% CI: 63%-81%) per Independent Review Committee (IRC) including 19% CR and 54% PR. With the follow-up period, the median DoR was 16.2 months by IRC and 13.4 months by investigator assessment; the median PFS was 18.6 months and 15.3 months, respectively. The most common non-hematologic adverse events (AEs) were gastrointestinal toxicity, pyrexia, and rash. Grade 3/4 neutropenia was reported in 76% of patients. Serious AEs were reported in 29 patients and five patients died during the study. Pharmacokinetic analysis indicated that the characteristics of bendamustine and its metabolites M3 and M4 were generally consistent with those reported for other ethnicities. CONCLUSION: Bendamustine is an active and effective therapy in Chinese patients with relapsed, indolent B-cell NHL, with a comparable risk/benefit relationship to that reported in North American patients.

OBJECTIVE: To investigate the clinical efficacy of high dose methotrexate (HD-MTX), temozolomide (TMZ), and rituximab (R) in the treatment of patients with primary central nervous system lymphoma (PCNSL). METHODS: Clinical data of patients with PCNSL diagnosed and treated in Guangdong Provincial People's Hospital from February 2010 to May 2017 were collected. First, patients were given 6-8 cycles of MTX (3.5 g/m RESULTS: There were 42 patients enrolled in the study, 17 cases in HD-MTX+TMZ group and 25 cases in HD-MTX+TMZ+R group. The median PFS and OS times in HD-MTX+TMZ+R group were 56.7 months and N/A, respectively, while, 7.3 months and 34.7 months in HD-MTX+TMZ group, respectively. In addition, there was no significant difference in median survival between patients who received TMZ maintenance therapy and those who were only actively monitored. During the induction period, all the patients had grade 1-2 nausea and vomiting, while in the consolidation treatment period, no grade 3/4 toxicity was observed. CONCLUSION The combination of HD-MTX+TMZ+R in the treatment of PCNSL patients shows a definite short-term effect, which can increase the survival rate of the patients. The side effects are mild, and the patients can generally tolerate.

METHODS: From January 2005 to December 2013, 83 patients with refractory/recurrent CD20 RESULTS: All the patient achieved complete response. The median follow.up time was 39 months. Both the two groups collected peripheral blood stem cells successfully, and had no difference in hematopoietic reconstitution time. Three patients in treatment group and six patients in control group relapsed and the three year overall survival and EFS in treatment group was significantly higher than that in control group, that is（93.0% vs 73.1%, P=0.037） and （89.5% vs 65.4%, P=0.034）, respectively. Subgroup analysis showed that: compared with the treatment group in which using R in the whole courses(before and after transplantation, and collection of stem cells) was superior to the control group in both OS and EFS, with the OS 97% vs 87.5% (P>0.05) and EFS 97% vs 76.2% (P=0.05) respectively. While stratified by the different courses of rituximab, the OS was 88.9% (1-2 courses, 9 cases), 93.1% (3-4 courses, 29 cases), 94.7%(more than 5 courses,19 cases), and EFS was 77.8%, 89.7% and 94.7%, respectively. CONCLUSION For the patients with refractory/recurrent CD20

Primary central nervous system lymphoma (PCNSL) is a rare aggressive non-Hodgkin's lymphoma outside the lymph nodes. At present, high-dose chemotherapy based on methotrexate is the standard induction therapy for newly diagnosed PCNSL, but the effective therapy of relapse/refractory and elderly PCNSL is still unclear. With the progress of clinical trials, new drugs and combined treatment method appear constantly, such as rituximab and ibrutinib, the remission rate of refractory and relapsed patients increased, while lenalidomide showed a good activity in the maintenance treatment of elderly patients. This review summarized briefly the recent advances of research on immunocheckpoint inhibitors, immunoregulatory agents, bruton tyrosine kinase (BTK) and PI3K/AKT/mTOR pathway inhibitors.

Lymphoma is one of the most common malignancies in China. In China, there were 6 829 new Hodgkin lymphoma cases and 2 807 deaths in 2020, with 92 834 new non-Hodgkin lymphoma cases and 54 351 deaths. Due to the complicated pathological subtypes and heterogeity, the treatment strategies for lymphoma vary largely. In recent years, with the deep understanding for the nature of lymphoma, much research progress has been achieved in the diagnosis and treatment, leading to a remarkable improvement in survival outcome of patients. In order to update the progress in the treatment of lymphoma worldwide timely, and further improve the level of standardized diagnosis and treatment of lymphoma in China, the China Anti-cancer Association Lymphoma Committee, Chinese Association for Clinical Oncologists, and Medical Oncology Branch of Chinese International Exchange and Promotion Association for Medical and Healthcare organized experts to formulate "Clinical practice guideline for lympoma in China (2021 Edition)" .
