Objective: To summarize the therapeutic effects of Chinese Children Leukemia Group-acute lymphoblastic leukemia (CCLG-ALL) 2018 regimen in children with T cell acute lymphoblastic leukemia (T-ALL) and to find out risk indicators for prognosis. Methods: This study was a prospective multicenter cohort study involving 299 newly diagnosed T-ALL children in 21 Grade A tertiary hospitals nationwide. All patients received CCLG-ALL 2018 regimen and clinical data for treatment efficacy evaluating was collected. Variables associated with event free survival (EFS) rate, overall survival (OS) rate and cumulative recurrence rate were evaluated by Lasso regression analysis (including variables selection, model construction and hazard ratio calculating). Results: A total of 299 newly diagnosed T-ALL children were included, accounting for 9.9% (299/3 026) of all ALL patients. Among these patients, there were 224 males and 75 females, and the age of onset was 7.0 (4.7, 10.6) years. All patients received CCLG-ALL 2018 regimen treatment. After 31.1 (17.3, 43.8) months follow-up, 3-year EFS, 3-year OS and cumulative recurrence rate of them were (83.2±2.7)%, (91.3±1.8)%, and (7.9±1.7)%, respectively. Minimal residual disease (MRD) greater than 10.00% on day 15 of induction therapy was a risk factor for EFS (HR=1.89, 95%CI 1.04-3.44), OS (HR=2.82, 95%CI 1.35-5.92), and cumulative recurrence rate (HR=3.05, 95%CI 1.46-6.34). Compared with the medium-risk group, the high-risk group had higher induction failure rate (5.2% (7/134) vs. 0 (0/145), P=0.016) and lower complete remission rate (88.8% (119/134) vs.97.9% (142/145),P=0.004). Most complications happened during induction therapy (95 cases), and the most common complication was serious infection (158 cases). Conclusions: CCLG-ALL 2018 regimen shows good prognosis. MRD greater than 10.00% on day 15 of induction therapy is a strong risk factor, which can indicate the prognosis in the early stage of the disease and guide the appropriate treatment.

A 68-year-old male was admitted due to fatigue and poor appetite and diagnosed pathologically as pancreatic adenocarcinoma with liver metastasis. The tumor marker carbohydrate antigen 199 (CA199) level was 2003.4 U/mL. The patient received two cycles of modified FOLFIRINOX plus immune checkpoint inhibitor (penpulimab). However, the tumor did not shrink and CA199 level was even higher. Anlotinib was added from the 3rd cycle, and the size of primary tumor and metastatic lesions were significantly reduced. Laparoscopic distal pancreatectomy and splenectomy as well as liver metastasis resection was performed. Three cycles of combined therapy were adopted after surgery followed by maintenance therapy with anlotinib plus penpulimab. There was no evidence of tumor recurrence during the follow-up (nearly 19 months since diagnosis).

OBJECTIVE: To detect the relative expression of IGLL1 (immunoglobulin lambda-like polypeptide 1) mRNA in bone marrow of children with T-cell acute lymphoblastic leukemia (T-ALL), and analyze its correlation with the clinical characteristics and prognosis of the patients, so as to clarify the clinical significance of IGLL1 in pediatric T-ALL patients. METHODS: A total of 56 pediatric T-ALL patients hospitalized in Children's Hospital of Soochow University from June 2012 to December 2017 and treated with CCLG-ALL 2008 regimen were selected. Transcriptome sequencing technology was used to detect the transcription level of IGLL1 gene in children with T-ALL. According to 25% of the IGLL1 transcription level (cutoff value:448), the enrolled children were divided into IGLL1 low expression group (17 cases) and IGLL1 high expression group (39 cases). Combined with clinical data, the correlation between the expression level of IGLL1 and prognosis of the patients was analyzed. RESULTS: The comparative analysis showed that the transcription level of IGLL1 was not correlated with the clinical characteristics of the patients, such as sex, age, bone marrow blast, white blood cell (WBC) count at initial diagnosis. The 5-year OS rate of patients with high IGLL1 expression was significantly higher than that of patients with low IGLL1 expression (76.9%±6.7% vs 47.1%±12.1%, P =0.018). Further comparison of relapse-free survival (RFS) rate between the two groups showed that the 5-year RFS rate of patients with high IGLL1 expression was higher than that of patients with low IGLL1 expression, but the difference between the two groups was not statistically significant (P =0.095). Multivariate COX analysis was conducted on common clinical prognostic factors (age, sex, WBC count at diagnosis, prednisone response on the 7th day, bone marrow response on the 15th day after treatment) and IGLL1 expression level, and the results showed that IGLL1 expression (P =0.012) and prednisone response (P =0.017) were independent risk factors for overall survival in pediatric T-ALL patients. CONCLUSION In pediatric T-ALL, the OS rate of children with high expression of IGLL1 gene was significantly higher than that of children with low expression of IGLL1 gene, and the expression level of IGLL1 gene was an independent factor affecting the survival of children with T-ALL, which suggests that IGLL1 is a marker of good clinical prognosis of children with T-ALL.

OBJECTIVE: To observe the efficacy and safety of different induction regimens of same total dosage of azacitidine (Aza), including standard dose (standard dose group) and low-dose long-term (adjusted dose group), in the treatment of elderly acute myeloid leukemia (AML). METHODS: A total of 103 elderly patients with AML (non-acute promyelocytic leukemia) from January 2020 to June 2021 were enrolled. Aza was administered at the standard dose of 75 mg/(m²·d) for 7 days in the standard dose group (50 cases), while at 100 mg/d for 7-12 days in the adjusted dose group (53 cases). The administration days in adjusted dose group was calculated based on the total standard dose of the patient's single course of treatment. The efficacy and safety between standard dose group and adjusted dose group were compared. Subgroup analysis were performed in the two groups for Aza alone, Aza combined with BCL-2 inhibitor, and Aza combined with low-dose chemotherapy for efficacy and safety. RESULTS: There were no significant differences in overall response rate (ORR), incidence of adverse reaction, and 1-year overall survival (OS) rate between standard dose group and adjusted dose group (P >0.05). The ORR of combination was higher than that of Aza alone (P < 0.05), while there was no significant difference in ORR between Aza combined with BCL-2 inhibitor and Aza combined with low-dose chemotherapy (P >0.05). The combination of BCL-2 inhibitor did not increase the incidence of adverse reactions compared wtih Aza alone. There was a higher risk of myelosuppression and pulmonary infection with a combination of low-dose chemotherapy than with a combination of BCL-2 inhibitor and Aza alone (P <0.05). No significant difference was observed in 1-year OS between Aza alone, Aza combined with BCL-2 inhibitor, and Aza combined with low-dose chemotherapy (P >0.05). CONCLUSIONS Both two induction regimens can be used in elderly AML patients who cannot tolerate intensive chemotherapy with similar overall effectiveness and safety. Aza combined with low-dose chemotherapy may result in increased ORR and an increased incidence of serious adverse reactions, and may not result in longer survival compared with Aza alone. Aza combined with BCL-2 inhibitor not only has similar effect in complete remission, objective response rate, and OS compared with Aza combined with low-dose chemotherapy, but also has higher safety.

Acute myeloid leukemia (AML) has highly heterogeneous clinical manifestations and poor prognosis, and traditional chemotherapy is the main treatment. In recent years, with the in-depth development of next-generation sequencing technology, the treatment of AML is gradually exploring the precise targeted therapy in the direction of molecular biology and immunophenotype. The advent of various small-molecule inhibitors and immune-targeted drugs has brought hope to patients who cannot tolerate intensive chemotherapy or with relapsed/refractory AML. Compared with traditional chemotherapy, targeted therapy has the advantages of significant curative effect and fewer adverse effects. This article reviews the latest research progress of targeted drug therapy for AML.

OBJECTIVE: To investigate the safety and the short-term efficacy of venetoclax combined with azacitidine followed by cladribine (VAC regimen) in children with refractory/ relapsed acute myeloid leukemia (AML). METHODS: The clinical data, treatment outcomes, complications, and blood product consumption of 6 children with refractory/relapsed AML treated with VAC regimen in the Children's Hospital of Soochow University from August 2021 to December 2021 were retrospectively analyzed. RESULTS: Among the 6 children, there were 1 male and 5 females. 5 cases were refractory AML, and 1 case was relapsed AML, which recurred again 16 months after allogeneic hematopoietic stem cell transplantation. 4 children were accompanied by chromosomes or genes that predicted poor prognosis, such as RUNX1, FLT3-ITD, KMT2A exon 2-exon 8 dup, MLL-AF6, 7q-, KMT2A exon 2-exon 10 dup, etc. After received VAC regimen, 4 cases achieved CR+CRi, 1 case achieved PR (only MRD did not relieve, MRD was 0.59%), and 1 case was NR (but the proportion of bone marrow blasts decreased). All 6 patients had grade Ⅳ neutropenia, and 4 patients had grade Ⅳ thrombocytopenia. During the period of neutropenia, none of the 6 children developed symptoms of infection such as fever, cough, and diarrhea. No treatment-related death occurred. CONCLUSION Venetoclax combined with azacitidine followed by cladribine provides a new treatment option for patients with relapsed/refractory AML who have poor efficacy in early induction remission theragy, showing good efficacy and safety.

OBJECTIVE: To observe the efficacy of veneclax combined with azacitidine in acute myeloid leukemia(AML) patients and explore the predictors of treatment response and recurrence. METHODS: The clinical data of 30 AML patients who received venetecla combined with azacitidine in the Affiliated Hospital of Southwest Medical University from January 2021 to September 2022 were retrospectively analyzed, composite complete remission (CRc) rate, overall response rate(ORR), and disease free survival(DFS) of patients were observed. RESULTS: After one course of trea- tment, CRc was 16 cases and ORR was 23/30. Patients with TP53 mutation had poor treatment response (P=0.009). After 1-2 courses, 25 patients reached CR/CRi. Finally, 24 patients who obtained CR/CRi were included to observe the duration of remission. 17 patients had relapse, with a median recurrence time of 3.9 (0.6-15.9) months. The Kaplan-Meier curve showed that MRD negative was a favorable factor for maintaining DFS status (HR=0.5647,95%CI:0.2179-1.464,P=0.007), while NRAS mutation was an adverse factor for maintaining DFS (HR=2.036,95%CI:0.6639-6.245,P=0.0003). Univariate combined multivariate cox regression analysis showed that NRAS mutation was an independent risk factor affecting DFS in patients (HR=5.569, P<0.05). In addition, the cases number of early recurrence in MRD negative group (n=8) and MRD non-negative group (n=9) was 0 and 5, respectively, the difference was statistically significant (P=0.012). There were 3 cases of early recurrence in the NRAS mutant group (n=4) and 2 cases in the NRAS wild-type group (n=13), the difference was statistically significant (P=0.022). CONCLUSION TP53 mutation is a predictor of poor response to veneclax in combination with azacitidine. With the conti-nuation of the combination chemotherapy regimen described above, NRAS mutation is an independent risk factor for DFS in patients. Moreover, the patients with non-negative MRD and NRAS mutations are at high risk of early recurrence.

OBJECTIVE: To explore the efficacy and survival of venetoclax based (VEN-based) regimen in the treatment of acute myeloid leukemia（AML）. METHODS: A retrospective study was conducted in patients who received VEN-based regimen and completed at least 1 course of efficacy evaluation at the The First Affiliated Hospital of Nanchang University from July 2019 to July 2022. The incidence of complete remission （CR）/CR with incomplete hematologic recovery （CRi） rate, objective remission rate（ORR） and survival of patients with different risk strati- fication and gene subtypes were analyzed. RESULTS: A total of 79 patients were enrolled, including 43 patients with newly diagnosed unfit AML （unfit AML） and 36 relapsed/refractory AML (R/R AML). The median age of the patients was 62(14-83) years old. 36 out of 79 patients achieved CR/CRi and the ORR of the whole cohort was 64.6%. The CR/CRi rate of unfit AML patients was significantly higher than that of R/R AML patients (60.5% vs 27.8%, P=0.004). In unfit AML cohort, the patients with NPM1 and IDH1/2 mutations were benefited, 8 out of 9 patients ahcieved CR/CRi, 7/8 and 5/8 patients achieved minimal residual disease (MRD) negativity, respectively. Six out of 9 patients with TET2 mutation achieved CR/CRi, 3/6 patients achieved MRD negativity. In R/R AML cohort, 2 out of 3 patients with RUNX1 mutation achieved CR/CRi, without MRD negative, while the CR/CRi rate of patients with other gene mutations was lower than 40%. The median follow-up time was 10.1(95%CI: 8.6-11.6) months. In whole cohort, the median overall survival (mOS) time was 9.1 months and the relapse free survival (RFS) time was not reached. The mOS and RFS of unfit AML patients were significantly longer than those of R/R AML patients (14.1 vs 6.8 months, P=0.013; not reached vs 3.3 months, P=0.000). In unfit AML cohort, the mOS of patients with NPM1 or IDH1/2 mutations was not reached, while that of patients without NPM1 or IDH1/2 mutations was 8.0 months (P=0.009; P=0.022). Furthermore, the mOS of patients with TP53 mutaion was significantly shorter than that of patients without TP53 mutation (5.2 vs 14.1 months， P=0.049). In R/R AML cohort, there was no significant difference in mOS between patients with mutation in each gene subtype and those without gene mutation (P>0.05). All patients had hematology adverse reactions, 91.1% patients had AE grade≥3. The most common non-hematology adverse reactions was infection, with an incidence of 91.1%. VEN-based regimen was tolerable for AML patients. CONCLUSION VEN-based regimen can achieve a high response rate, especially in unfit AML with acceptable safety, and some patients can achieve MRD negative. It is also effective in NPM1-, IDH1/2-positive patients with long survival time.

OBJECTIVE: To explore the short-term efficacy and adverse reactions of orelabrutinib combined with high-dose methotrexate (HD-MTX) in the first-line treatment of elderly high-risk primary central nervous system lymphoma (PCNSL), as well as the survival of patients. METHODS: Twenty-five elderly patients with high-risk primary central nervous system diffuse large B-cell lymphoma admitted to Fujian Provincial Hospital from June 2016 to June 2022 were enrolled in this study, and complete clinical data from all patients were collected retrospectively, and the cut-off for follow-up was December 2022. 15 patients had received temmozolomide combined with HD-MTX regimen for at least four cycles, sequential lenalidomide maintenance therapy, while 10 patients had received orelabrutinib combined with HD-MTX regimen for at least four cycles, sequential orelabrutinib maintenance therapy. The short-term efficacy and adverse reactions of the two groups of patients after treatment were observed. Kaplan-Meier was used to analyze the progression-free survival (PFS) and time to progression (TTP). RESULTS: The objective response rate (ORR) and 2-year median FPS of orelabrutinib combined with HD-MTX regimen group were similar to the temozolomide combined with HD-MTX regimen group (ORR: 100% vs 66.7%; 2-year median PFS: 16 months vs 15 months, P>0.05). The 2-year median TTP of the orelabrutinib+HD-MTX regimen group was better than that of the temozolomide+HD-MTX regimen group (not reached vs 12 months, P<0.05). There were no significant differences in adverse reactions such as gastrointestinal reactions, bone marrow suppression, liver and kidney damage, cardiotoxicity, pneumonia and bleeding between these two groups (P>0.05). CONCLUSION For elderly patients with high-risk PCNSL, orelabrutinib combined with HD-MTX has reliable short-term efficacy, good safety, and tolerable adverse reactions, which is worthy of clinical promotion.

OBJECTIVE: To analyze the clinical-biological features and outcomes of patients with mantle cell lymphoma (MCL). METHODS: The clinical and laboratory data of 104 patients with newly diagnosed MCL who were admitted to the Department of Hematology, Fujian Medical University Union Hospital from January 2011 to December 2019 were retrospectively analyzed, and the efficacy was observed through survival analysis. RESULTS: Among 104 MCL patients, 88 were male and 16 were female. The median age was 54 (25-79) years old, 93.0% (93/100) of the patients with advanced stage (III and IV stages) and 48.08% (50/104) of the patients with bone marrow infiltration. Patients with Ki-67≥50% had higher WBC counts and LDH levels. Univariate analysis showed that the patients with WBC≥15×10⁹/L, bone marrow involvement, high LDH, high β₂-MG levels, Ki-67≥50%, SOX11^-, had lower OS and EFS rates (P =0.005, 0.049, 0.033, 0.025, 0.042, 0.018 and 0.001, 0.021, 0.024, 0.035, 0.014, 0.026). The OS rate and EFS rate of patients in R-CHOP and R-Hyper-CVAD treatment groups were significantly higher than those in other treatment groups (P =0.02, 0.002 and P =0.001, 0.001). Patients with autologous stem cell transplantation (ASCT) had higher OS rate and EFS rate (P =0.037, 0.013). Multivariate COX analysis showed that only WBC count, SOX11 expression and whether achieved CR after 4 courses treatment were the independent factors affecting the prognosis. CONCLUSION MCL mainly occur in elderly men. There are many factors affecting patients' survival, while WBC≥15×10⁹/L, negative expression of SOX11 and failure to achieve CR after 4 courses of treatment are adverse factors for MCL patients.
