Objective: To explore the prognostic factors of extracellular NK/T cell lymphoma (ENKTL) treated with pegaspargase/L-asparaginase. Methods: The clinical data of 656 ENKTL patients diagnosed at 11 medical centers in the Huaihai Lymphoma Working Group from March 2014 to April 2021 were retrospectively analyzed. The patients were randomly divided into two groups: a training set (460 cases) and a validation set (196 cases) at 7∶3, and the prognostic factors of the patients were analyzed. A prognostic scoring system was established, and the predictive performance of different models was compared. Results: Patients' median age was 46 (34, 57) years, with 456 males (69.5% ) and 561 nasal involvement (85.5% ). 203 patients (30.9% ) received a chemotherapy regimen based on L-asparaginase combined with anthracyclines, and the 5-year overall survival rate of patients treated with P-GEMOX regimen (pegaspargase+gemcitabine+oxaliplatin) was better than those treated with SMILE regimen (methotrexate+dexamethasone+cyclophosphamide+L-asparaginase+etoposide) (85.9% vs 63.8% ; P=0.004). The results of multivariate analysis showed that gender, CA stage, the Eastern Cooperative Oncology Group performance status (ECOG PS) score, HGB, and EB virus DNA were independent influencing factors for the prognosis of ENKTL patients (P<0.05). In this study, the predictive performance of the prognostic factors is superior to the international prognostic index, Korean prognostic index, and prognostic index of natural killer lymphoma. Conclusion: Gender, CA stage, ECOG PS score, HGB, and EB virus DNA are prognostic factors for ENKTL patients treated with pegaspargase/L-asparaginase.

OBJECTIVE: To evaluate the efficacy and safety of etoposide combined with cyclophosphamide (EC) regimen for mobilization of autologous peripheral blood stem cells (APBSCs) in patients with multiple myeloma (MM). METHODS: The clinical data of 48 MM patients who received APBSC transplantation (APBSCT) in Department of Hematology of the First Affiliated Hospital of Nanchang University from January 2015 to October 2021 were retrospectively analyzed. The mobilization success rate and mobilization optimal rate of EC regimen were counted, and its effect on transplant efficacy, adverse reactions, hematopoietic reconstitution after transplantation, and survival time of MM patients were analyzed. RESULTS: APBSCs were collected on day 14 (10-19) after EC administration. The median of collected CD34⁺ cells was 6.82 (1.27-22.57)×10⁶/kg, and the median number of apheresis session was 2 (1-4). The mobilization success rate (collecting CD34⁺ cells≥2×10⁶ cells/kg after completion of apheresis) was 98% (47/48), and mobilization optimal rate (collecting CD34⁺ cells≥5×10⁶ cells/kg after completion of apheresis) was 71% (34/48). The depth of remission were improved after APBSCT, and the complete remission (CR) rate increased from 45.8% before transplantation to 87.5% after transplantation (P <0.01). There was no transplant-related death, no blood transfusion during mobilization, and no mucositis occurred in the patients. The most common complication was neutropenia, with an incidence of 75.0% (36/48). After transplantation, all the patients successfully achieved hematopoietic reconstitution. The median time to neutrophil engraftment was 10 (9-26) days, and median time to platelet engraftment was 10 (8-33) days. By the end of follow-up, both the median progression-free survival (PFS) and overall survival (OS) time were not reached. The 5-year estimated PFS rate and OS rate was 53.8% and 82.4%, respectively. CONCLUSION The EC regimen for mobilization of APBSC has a high acquisition success rate and controllable adverse reactions, which can be an effective and safe mobilization regimen in MM patients.

BACKGROUND: To compare the efficacy and safety of dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin plus rituximab (DA-EPOCH-R) with standard rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in Waldeyer's ring diffuse large B-cell lymphoma (WR-DLBCL) at a single institution. METHODS: This retrospective study included 115 newly diagnosed patients with WR-DLBCL, of whom 68 patients received R-CHOP, and 47 patients received DA-EPOCH-R as their first-line treatment. The baseline features of the two groups were well balanced using a 1:1 propensity score matching method, and a total of 84 cases were obtained, including respective 42 cases in the R-CHOP and DA-EPOCH-R groups, for further survival and prognosis analysis. The primary objectives included progression-free survival (PFS) and overall survival (OS). RESULTS: During a median follow-up of 45 months, there were nine (21.4%) deaths in the R-CHOP group and two (4.8%) in the DA-EPOCH-R group. Kaplan-Meier analysis showed statistically significant improvements in PFS and OS in patients with DA-EPOCH-R compared with those treated with R-CHOP (log-rank test, P  = 0.025 and P  = 0.035, respectively). The 2-year PFS and OS rates in the DA-EPOCH-R group were 90.1% (95% confidence interval [CI]: 81.4-99.8%) and 95.2% (95% CI: 89.0-100.0%), respectively, and 80.5% (95% CI: 69.3-93.6%) and 90.5% (95% CI: 52.8-99.8%) in the R-CHOP group. Patients without B symptoms and elevated lactate dehydrogenase levels had a higher PFS in the DA-EPOCH-R group, with P values of 0.038 (hazard ratio [HR]: 0.11; 95% CI: 0.01-0.88) and 0.042 (HR: 0.19; 95% CI: 0.04-0.94), respectively. There were no statistically significant differences in clinical responses and treatment-related toxicities between the two groups. CONCLUSION Compared with patients received R-CHOP, those treated by DA-EPOCH-R had superior PFS, OS, and controlled toxicity in patients with WR-DLBCL.

Extracellular matrix (ECM) has been implicated in tumor progress and chemosensitivity. Ovarian cancer brings a great threat to the health of women with a significant feature of high mortality and poor prognosis. However, the potential significance of matrix stiffness in the pattern of long non-coding RNAs (lncRNAs) expression and ovarian cancer drug sensitivity is still largely unkown. Here, based on RNA-seq data of ovarian cancer cell cultured on substrates with different stiffness, we found that a great amount of lncRNAs were upregulated in stiff group, whereas SNHG8 was significantly downregulated, which was further verified in ovarian cancer cells cultured on polydimethylsiloxane (PDMS) hydrogel. Knockdown of SNHG8 led to an impaired efficiency of homologous repair, and decreased cellular sensitivity to both etoposide and cisplatin. Meanwhile, the results of the GEPIA analysis indicated that the expression of SNHG8 was significantly decreased in ovarian cancer tissues, which was negatively correlated with the overall survival of patients with ovarian cancer. In conclusion, matrix stiffening related lncRNA SNHG8 is closely related to chemosensitivity and prognosis of ovarian cancer, which might be a novel molecular marker for chemotherapy drug instruction and prognosis prediction.

Objective: To investigate the clinical features, treatment regime, and outcome of pediatric acute myeloid leukemia (AML) with DEK-NUP214 fusion gene. Methods: The clinical data, genetic and molecular results, treatment process and survival status of 7 cases of DEK-NUP214 fusion gene positive AML children admitted to the Pediatric Blood Diseases Center of Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences from May 2015 to February 2022 were analyzed retrospectively. Results: DEK-NUP214 fusion gene positive AML accounted for 1.02% (7/683) of pediatric AML diagnosed in the same period, with 4 males and 3 females. The age of disease onset was 8.2 (7.5, 9.5) years. The blast percentage in bone marrow was 0.275 (0.225, 0.480), and 6 cases were M5 by FAB classification. Pathological hematopoiesis was observed in all cases except for one whose bone marrow morphology was unknown. Three cases carried FLT3-ITD mutations, 4 cases carried NRAS mutations, and 2 cases carried KRAS mutations. After diagnosis, 4 cases received IAE induction regimen (idarubicin, cytarabine and etoposide), 1 case received MAE induction regimen (mitoxantrone, cytarabine and etoposide), 1 case received DAH induction regimen (daunorubicin, cytarabine and homoharringtonine) and 1 case received DAE induction regimen (daunorubicin, cytarabine and etoposide). Complete remission was achieved in 3 cases after one course of induction. Four cases who did not achieved complete remission received CAG (aclarubicin, cytarabine and granulocyte colony-stimulating factor), IAH (idarubicin, cytarabine and homoharringtonine), CAG combined with cladribine, and HAG (homoharringtonine, cytarabine and granulocyte colony-stimulating factor) combined with cladribine reinduction therapy, respectively, all 4 cases reached complete remission. Six patients received hematopoietic stem cell transplantation (HSCT) after 1-2 sessions of intensive consolidation treatment, except that one case was lost to follow-up after complete remission. The time from diagnosis to HSCT was 143 (121, 174) days. Before HSCT, one case was positive for flow cytometry minimal residual disease and 3 cases were positive for DEK-NUP214 fusion gene. Three cases accepted haploid donors, 2 cases accepted unrelated cord blood donors, and 1 case accepted matched sibling donor. The follow-up time was 20.4 (12.9, 53.1) months, the overall survival and event free survival rates were all 100%. Conclusions: Pediatric AML with DEK-NUP214 fusion gene is a unique and rare subtype, often diagnosed in relatively older children. The disease is characterized with a low blast percentage in bone marrow, significant pathological hematopoiesis and a high mutation rate in FLT3-ITD and RAS genes. Low remission rate by chemotherapy only and very high recurrence rate indicate its high malignancy and poor prognosis. Early HSCT after the first complete remission can improve its prognosis.

Objective: To understand the social security situation of current cases of pneumoconiosis in non-coal mine industries in Jiangsu Province, and to provide reference for the treatment and security work of pneumoconiosis patients. Methods: From January to October 2020, a follow-up survey was conducted on 4038 cases of pneumoconiosis in non-coal mine industries of the province from October 1949 to December 2019. The age, type of pneumoconiosis, industry type, and social security status of the patients were collected. Namely, work-related injury insurance, employer compensation, basic medical insurance for urban and rural residents, major illness insurance, etc. SPSS 19.0 was used for statistical description and analysis. Results: The cases of pneumoconiosis in non-coal mine industries in Jiangsu Province ranged in age from 36 to 105 (70.78±8.43) years old, and had been exposed to dust for 1 to 55 (19.27±9.29) years. Silicosis was the main form (3875 cases, 95.96%), and non-metallic mining and dressing industry was the main form (2618 cases, 64.83%). A total of 3991 cases (98.84%) of pneumoconiosis patients enjoyed social security, most of them were urban and rural residents with basic medical insurance (3624 cases, 89.75%), but there were still 47 patients without any social security. 15 cases (0.37%) enjoyed the subsistence allowance, with the monthly allowance amount ranging from 104 to 3960 yuan, with the average amount of 954.87 yuan/month. Conclusion: In Jiangsu Province, the proportion of pneumoconiosis patients in non-coal mine industries enjoying social security is relatively high, but there are still patients who do not enjoy any social security, and the difference in the amount of subsistence allowance is slightly larger. It is necessary to further improve the medical security of pneumoconiosis patients and improve their quality of life.

OBJECTIVE: To investigate the clinical characteristics, diagnosis, and treatment of one patient with primary adrenal natural killer/T-cell lymphoma (PANKTCL), and to strengthen the understanding of this rare type of lymphoma. METHODS: The clinical manifestations, diagnosis and treatment process, and prognosis of the patient admitted in our hospital were retrospectively analyzed. RESULTS: Combined with pathology, imaging, bone marrow examination， etc, the patient was diagnosed with PANKTCL (CA stage, stage II; PINK-E score 3, high-risk group). Six cycles of "P-GemOx+VP-16" regimen（gemcitabine 1 g/m² d1 + oxaliplatin 100 mg/m² d 1 + etoposide 60 mg/m² d 2-4 + polyethylene glycol conjugated asparaginase 3 750 IU d 5） was performed, and complete response was assessed in 4 cycles. Maintenance therapy with sintilimab was administered after the completion of chemotherapy. Eight months after the complete response, the patient experienced disease recurrence and underwent a total of four courses of chemotherapy, during which hemophagocytic syndrome occurred. The patient died of disease progression 1 month later. CONCLUSION PANKTCL is rare, relapses easily, and has a worse prognosis. The choice of the "P-GemOx+VP-16" regimen combined with sintilimab help to improve the survival prognosis of patient with non-upper aerodigestive tract natural killer /T-cell lymphoma.

Objective: To investigate the pathological characteristics and clinical prognosis of nodular sclerosis grade 2 of classic Hodgkin's lymphoma (cHL-NS2) in our cancer center. Methods: A retrospective collection of 23 cases of cHL-NS2 admitted in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from July 2008 to April 2019 was performed. Fifty-five cases of nodular sclerosis grade 1 of classical Hodgkin's lymphoma (cHL-NS1) during the same period were selected as control group. Survival curves were plotted using the Kaplan-Meier method, and Cox regression model was used to analyze the influencing factors for survival. Results: The median age of 23 cases of cHL-NS2 was 30 years old. Five cases had extra nodal invasion, and 19 cases were Ⅰ-Ⅱ stage based on Ann Arbor system. The pathological morphology of cHL-NS2 showed that the lymph node structure was completely destroyed and was divided into nodules by thick collagen. The tumor cells in the nodules were abundant and proliferated in sheets. The boundaries between the tumor cells were not clear. The incidence of tumor necrosis in cHL-NS2 was 43.5% (10/23), which was significantly higher than 18.2% (10/55) in cHL-NS1 (P=0.040). The 3-year progression-free survival (PFS) rate of patients in the cHL-NS2 group was 58.1%, which was significantly lower than 89.7% in the cHL-NS1 group (P=0.002). In all of 78 cases, the 3-year PFS rate of patients who did not obtain complete response (CR) was 67.1%, which was significantly lower than 92.2% in patients who achieved CR (P=0.030). Multivariate Cox regression analysis demonstrated that both cHL-NS2 and failure to obtain CR by first-line treatment were independent indicators for short PFS time (P<0.05). Conclusions: In cHL-NS2, the morphology of tumor cells are diverse, and tumor necrosis can be easily found. Under the current first-line treatments of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) or bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP), cHL-NS2 is an independent indicator for worse PFS.

Hemophagocytic syndrome (HPS) is a severe disease characterized by excessive release of inflammatory cytokines caused by abnormal activation of lymphocytes and macrophages, which can cause multiple organ damage and even death. Panniculitis is a disease characterized by inflammation of subcutaneous adipose tissue. We effectively treated 2 patients with panniculitis-associated HPS with ruxolitinib. Case 1: A 70-year-old male started with intermittent plantar swelling and pain, and then developed leukocytosis, mild anemia, multiple red maculopapules with painless subcutaneous nodules on the forehead, neck and bilateral lower legs. The patient was treated with prednisone and leflunomide for improvement. After that, repeated fever and rash occurred again. After admission to our hospital, we found his leukocyte and hemoglobin decreased, ferritin raised, fibrinogen and natural killer (NK) cell activity decreased, and hemophagocytic cells were found in bone marrow aspiration. The skin pathology was consistent with non-suppurative nodular panniculitis. He was diagnosed with nodular panniculitis associa-ted HPS. He was treated with glucocorticoid, cyclosporine, etoposide and gamma globule, but the disease was not completely controlled. After adjusting etoposide to ruxolitinib, his symptoms and abnormal laboratory findings returned to normal. After 2 months he stopped using ruxolitinib due to repeated infections. During the follow-up, though the prednisone dose was tapered, his condition was stable. Case 2: A 46-year-old female patient developed from intermittent fever, erythematous nodular rash with tenderness, leukopenia, and abnormal liver function. antibiotic therapy was ineffective. She improved after glucocorticoid treatment, and relapsed after glucocorticoid reduction. There were fever, limb nodules, erythema with ulcerative necrosis, intermittent abdominal pain when she came to our hospital. Blood examination showed that her white blood cells, red blood cells and platelets were decreased, fibrinogen was decreased, triglyceride was increased, ferritin and soluble interleukin-2 receptor(SIL-2R/sCD25) were significantly raised, and hemophagocytic cells were found in bone marrow aspiration. It was found that Epstein-Barr virus DNA was transiently positive, skin Staphylococcus aureus infection, and pulmonary Aspergillus flavus infection, but C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were normal, and no evidence of tumor and other infection was found. Skin pathology was considered panniculitis. The diagnosis was panniculitis, HPS and complicated infection. Antibiotic therapy and symptomatic blood transfusion were given first, but the disease was not controlled. Later, dexamethasone was given, and the condition improved, but the disease recurred after reducing the dose of dexamethasone. Due to the combination of multiple infections, the application of etoposide had a high risk of infection spread. Ruxolitinib, dexamethasone, and anti-infective therapy were given, and her condition remained stable after dexamethasone withdrawal. After 2 months of medication, she stopped using ruxolitinib. One week after stopping using ruxolitinib, she developed fever and died after 2 weeks of antibiotic therapy treatment in a local hospital. In conclusion, panniculitis and HPS are related in etiology, pathogenic mechanism and clinical manifestations. Abnormal activation of Janus-kinase and signal transduction activator of transcription pathway and abnormal release of inflammatory factors play an important role in the pathogenesis of the two diseases. The report suggests that ruxolitinib is effective and has broad prospects in the treatment of panniculitis associated HPS.
