Long-Term Remission in T315I+ Relapsed Philadelphia Chromosome-Positive Acute Lymphoblastic Leukemia with Blinatumomab and Allogeneic Stem Cell Transplantation: Two Case Studies. AMERICAN JOURNAL OF CASE REPORTS 2024; 25:e944956. [PMID: 39099157 PMCID: PMC11318714 DOI: 10.12659/ajcr.944956] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2024] [Revised: 07/02/2024] [Accepted: 06/10/2024] [Indexed: 08/06/2024]
Abstract
BACKGROUND Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) in adults has a poor prognosis with conventional chemotherapy. Treatment with tyrosine kinase inhibitors (TKIs) followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT) has improved clinical outcomes; however, the relapse rate is still high. Therapeutic options for patients with relapsed/refractory (R/R) Ph+ ALL are scarce, with very few studies focusing on these patients. Blinatumomab is a novel bispecific T-cell engager antibody construct showing promising efficacy in R/R Ph+ ALL. CASE REPORT Here, we present 2 cases of relapsed Ph+ ALL with T315I mutation refractory to multiple TKIs and chemotherapy. Patient 1 was a 48-year-old woman who had increased leukocytes in her peripheral blood cells, with 90% abnormal cells and decreased platelets. Bone marrow (BM) smear showed 95% blasts. Patient 2 was a 20-year-old man who had leukocytosis with thrombocytopenia, while all other parameters were normal. BM aspirate showed 98% immature granulocytes/blasts. The immunophenotypic observations of both the patients on BM were consistent with the presence of ALL. Both patients were effectively treated with a combination of blinatumomab and allo-HSCT and achieved complete remission in 1 month with minimal residual disease negativity and remained in remission for a long period. CONCLUSIONS The findings suggest, that for patients with R/R Ph+ ALL with T315I mutation who respond poorly to TKIs, salvage therapy with blinatumomab is a potentially effective treatment for improving clinical outcomes. The treatment with blinatumomab can further act as a bridge to HSCT in these patients, helping them to attain deeper remission.

An integrated classification of tumor suppressor IKZF1 inactivation and oncogenic activation in Philadelphia chromosome-like acute lymphoblastic leukemia. Hemasphere 2024; 8:e82. [PMID: 38774654 PMCID: PMC11106797 DOI: 10.1002/hem3.82] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 03/14/2024] [Accepted: 04/11/2024] [Indexed: 05/24/2024] Open
Abstract
Philadelphia chromosome (Ph)-like acute lymphoblastic leukemia (ALL) is recognized for its genetic and clinical diversity. In this study, we identified a novel high-risk subset of Ph-like ALL, characterized by the activation of oncogenic signaling and the inactivation of the tumor suppressor gene IKZF1, resulting in a dismal outcome. The association between cytogenetic aberrations and clinical features was assessed on a cohort of 191 patients with Ph-like ALL. Our findings revealed that patients with inactivation of IKZF1 combined with activation of oncogenic signaling (CRLF2/EPOR/JAK2 rearrangements or p-CRKL/p-STAT5 high expression) had the worst outcome (3-year overall survival [OS] of 28.8% vs. 80.1% for others, p < 0.001; 2-year event-free survival [EFS] of 6.5% vs. 57.0% for others, p < 0.001). Multivariable analysis demonstrated that this high-risk feature was an independent inferior prognostic factor (adjusted hazard ratio for OS = 4.55, 95% confidence interval [CI]: 2.35-8.81, p < 0.001; adjusted hazard ratio for EFS = 3.27, 95% CI: 1.99-5.39, p < 0.001). Allogeneic hematopoietic stem cell transplantation was associated with improved prognoses in patients within the high-risk subgroup. In conclusion, this study identified a clinically distinct entity that possesses effective prognostic features and provides potential guidance for refining risk stratification in Ph-like ALL.

Abstract
Acute promyelocytic leukemia (APL), which was once considered one of the deadliest types of leukemia, has become a curable malignancy since the introduction of all-trans retinoic acid (ATRA) and arsenic trioxide (ATO) as clinical treatments. ATO, which has become the first-line therapeutic agent for APL, is derived from the natural mineral product arsenic, exemplifying an important role of natural products in the treatment of APL. Many other natural products, ranging from small-molecule compounds to herbal extracts, have also demonstrated great potential for the treatment and adjuvant therapy of APL. In this review, we summarize the natural products and representative components that have demonstrated biological activity for the treatment of APL. We also discuss future directions in better exploring their medicinal value, which may provide a reference for subsequent new drug development and combination therapy programs.

Abstract
Objective: To investigated the safety and efficacy of donor-derived CD19+ or sequential CD19+ CD22+ chimeric antigen receptor T-cell (CAR-T) therapy in patients with B-cell acute lymphoblastic leukemia (B-ALL) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: The data of 22 patients with B-ALL who relapsed after allo-HSCT and who underwent donor-derived CAR-T therapy at the Zhujiang Hospital of Southern Medical University and the 920th Hospital of Joint Logistics Support Force of the People's Liberation Army of China from September 2015 to December 2022 were retrospectively analyzed. The primary endpoint was overall survival (OS), and the secondary endpoints were event-free survival (EFS), complete remission (CR) rate, and Grade 3-4 adverse events. Results: A total of 81.82% (n=18) of the 22 patients achieved minimal residual disease-negative CR after CAR-T infusion. The median follow-up time was 1037 (95% CI 546-1509) days, and the median OS and EFS were 287 (95% CI 132-441) days and 212 (95% CI 120-303) days, respectively. The 6-month OS and EFS rates were 67.90% (95% CI 48.30%-84.50%) and 58.70% (95% CI 37.92%-79.48%), respectively, and the 1-year OS and EFS rates were 41.10% (95% CI 19.15%-63.05%) and 34.30% (95% CI 13.92%-54.68%), respectively. Grade 1-2 cytokine release syndrome occurred in 36.36% (n=8) of the patients, and grade 3-4 occurred in 13.64% of the patients (n=3). Grade 2 and 4 graft-versus-host disease occurred in two patients. Conclusion: Donor-derived CAR-T therapy is safe and effective in patients with relapsed B-ALL after allo-HSCT.

Abstract
Objective: To evaluate the efficacy and safety of chimeric antigen receptor T-cell (CAR-T) therapy followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with Ph-like acute lymphoblastic leukemia (Ph-ALL) . Methods: Patients with Ph-ALL who underwent CAR-T therapy followed by allo-HSCT from March 2018 to August 2023 at the First Affiliated Hospital of Soochow University were included, and their clinical data were retrospectively analyzed. Results: Of the 21 patients, 14 were male and 7 were female. The median age at the time of CAR-T therapy was 22 (6-50) years. Seven patients had ABL1-like rearrangements, and 14 had JAK-STAT rearrangements. Prior to CAR-T therapy, 12 patients experienced hematologic relapse; 7 were multiparameter flow cytometry minimal residual disease (MFC-MRD) -positive and 2 were MFC-MRD-negative. CAR-T cells were derived from patients' autologous lymphocytes. Nine patients were treated with CD19 CAR-T cells, and 12 were treated with CD19/CD22 CAR-T cells. After assessment on day 28 after CAR-T therapy, 95.2% of the patients achieved complete remission, with an MRD-negative remission rate of 75%. Nineteen patients developed grade 0-2 cytokine release syndrome (CRS) and 2 patients suffered grade 3 CRS, all cases of which resolved after treatment. All patients underwent allo-HSCT after CAR-T therapy. The median time from CAR-T therapy to allo-HSCT was 63 (38-114) days. Five patients experienced relapse after CAR-T therapy, including four with hematologic relapse and one with molecular relapse. The 3-year overall survival (OS) rates in the ABL1 and JAK-STAT groups were (83.3±15.2) % and (66.6±17.2) %, respectively (P=0.68) . The 3-year relapse-free survival (RFS) rates were (50.0±20.4) % and (55.6±15.4) % in the ABL1 and JAK-STAT groups, respectively. There was no significant difference in 3-year OS or RFS between the two groups. Conclusions: CAR-T therapy followed by allo-HSCT leads to rapid remission in most patients with Ph-ALL and prolongs leukemia-free survival.

Abstract
Objective: Murine CD19 chimeric antigen receptor T-cell (CAR-T) products have been approved for the treatment of refractory/relapsed (R/R) B-cell acute lymphocytic leukemia (B-ALL) ; moreover, humanized products are also undergoing clinical trials. This study aimed to explore the differences in safety and short- and long-term follow-up efficacy between humanized and murine CD19 CAR-T-cells for treating relapsed and refractory B-ALL. Methods: Clinical data of 80 patients with R/R B-ALL treated with CD19-targeted CAR-T-cells at the Union Hospital of Tongji Medical College of Huazhong University of Science and Technology between May 2016 and March 2023 were analyzed, which included 31 patients with murine CAR-T and 49 with humanized products. Results: The proportion of patients with cytokine-release syndrome (CRS) in the murine and humanized groups was 63.1% and 65.3%, respectively. Moreover, a higher proportion of patients suffered from severe CRS in the murine group than in the humanized CAR-T group (19.4% vs 8.2%, P=0.174). Furthermore, one patient per group died of grade 5 CRS. The incidence of grade 1-2 immune effector cell-associated neurotoxicity syndrome (ICANS) was 12.9% and 6.1%, respectively; severe ICANS were not observed. Among patients receiving murine CAR-T-cells, an overall response (OR) was observed in 74.2%. Conversely, the OR rate of patients receiving humanized CAR-T-cells was 87.8%. During the median follow-up time of 10.5 months, the median recurrence-free survival (RFS) of patients with murine CAR-T-cells was 12 months, which was as long as that of patients with humanized CAR-T-cells. The median overall survival (OS) were not reached in both groups. Of the 45 patients with a bone marrow burden over 20% at baseline, humanized CAR-T therapy was associated with a significantly improved RFS (43.25% vs 33.33%, P=0.027). Bridging transplantation was an independent factor in prolonging OS (χ(2)=8.017, P=0.005) and PFS (χ(2)=6.584, P=0.010). Common risk factors, such as age, high proportion of bone marrow blasts, and BCR-ABL fusion gene expression, had no significant effect on patients' long-term follow-up outcomes. Three patients reached complete remission after reinfusion of humanized CAR-T-cells. However, one patient relapsed one month after his second infusion of murine CAR-T-cells. Conclusions: The results indicate that humanized CAR-T therapy showed durable efficacy in patients with a higher tumor burden in the bone marrow without any influence on safety. Moreover, it could overcome immunogenicity-induced CAR-T resistance, providing treatment options for patients who were not treated successfully with CAR-T therapies.

Abstract
Objective: To analyze the survival and influencing factors of chimeric antigen receptor (CAR) T-cell therapy in relapsed/refractory acute B-cell lymphoblastic leukemia (R/R B-ALL) . Methods: Clinical information of patients who received CAR-T-cell therapy and achieved complete remission of R/R B-ALL between May 2015 and June 2018 at the Shaanxi Provincial People's Hospital was obtained. Kaplan-Meier analysis was used to evaluate the overall survival (OS) and leukemia-free survival (LFS) times of patients, and Cox regression analysis was performed to analyze the prognostic factors that affect patient survival after CAR-T therapy. Results: Among the 38 patients with R/R B-ALL, 21 were men, with a median age of 25 (6-59) years and a median OS time of 18 (95% CI 3-33) months. Multivariate Cox regression analysis showed that positive MLL-AF4 fusion gene expression was an independent risk factor for OS and LFS (OS: HR=4.888, 95% CI 1.375-17.374, P=0.014; LFS: HR=6.683, 95% CI 1.815-24.608, P=0.004). Maintenance therapy was a protective factor for OS and LFS (OS: HR=0.153, 95% CI 0.054-0.432, P<0.001; LFS: HR=0.138, 95% CI 0.050-0.382, P<0.001). In patients with MRD negative conversion, LFS benefit (HR=0.209, 95% CI 0.055-0.797, P=0.022) and OS difference was statistically insignificant (P=0.111). Moreover, patients with high tumor burden were risk factors for OS and LFS at the level of 0.1 (OS: HR=2.662, 95% CI 0.987-7.184, P=0.053; LFS: HR=2.452, 95% CI 0.949-6.339, P=0.064) . Conclusion: High tumor burden and high-risk genetics may affect the long-term survival rate of patients with R/R B-ALL receiving CAR-T, and lenalidomide-based maintenance therapy may improve their prognosis.

Abstract
The present report describes a case of Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ALL) with pericardial invasion following bone marrow transplantation. The patient exhibited recurrent pericardial effusion accompanied by wheezing symptoms. Despite undergoing multiple pericardial punctures and drainage procedures, pericardial injections, and systemic treatment, the patient continued to experience recurrent pericardial effusion. Ultimately, the patient underwent whole-heart radiotherapy, resulting in complete resolution of the pericardial effusion. After a follow-up period of 10 months, the pericardial effusion remained well-controlled, and there were no significant impairments in cardiac function. In conclusion, radiotherapy may be considered as a viable treatment option for refractory leukemia cases presenting with pericardial effusion.

Abstract
Objective: To explore the efficacy and safety of Venetoclax combined with multidrug chemotherapy in patients with relapsed or refractory early T-cell precursor acute lymphoblastic leukemia (R/R ETP-ALL) . Methods: This study retrospectively analyzed 15 patients with R/R ETP-ALL who received Venetoclax combined with multidrug chemotherapy from December 2018 to February 2022. Among them, eight cases were combined with demethylated drugs, four cases were combined with demethylated drugs and HAAG chemotherapy regimen, two cases were combined with demethylated drugs and CAG regimen, and one case was combined with Cladribine. Specific usage and dosage of Venetoclax: 100 mg on day 1, 200 mg on day 2, 400 mg on day 3-28, orally; when combined with azole antifungal drugs, dosage was reduced to 100 mg/d. Results: Fifteen patients (10 males and 5 females) with R/R ETP-ALL were treated with Venetoclax and multidrug chemotherapy with a median age of 35 (12-42) years old. Of 4 refractory and 11 relapsed patients, the efficacy was evaluated on the 21th day following combined chemotherapy: the overall response rate, the complete response (CR) rate, and the CR with incomplete hematological recovery (CRi) rate were 67.7% (10/15), 60.0% (9/15), and 6.7% (1/15), respectively. For the overall study population, the 12-month overall survival (OS) rate was 60.0%, and the median OS was 17.7 months. The disease-free survival (DFS) rate of all CR patients at 12 months was 60.0%, and the median DFS did not reach. About 14 patients had Ⅲ-Ⅳ hematological toxicity, but these adverse reactions were all controllable. No adverse reaction in the nervous system and tumor lysis syndrome occurred in this study, and no adverse reaction of organs above grade Ⅲ occurred. Conclusion: Venetoclax combined with multidrug chemotherapy may be a safe and promising treatment option for patients with R/R ETP-ALL.

Abstract
OBJECTIVE This study aimed to investigate the clinical effects of recombinant human interleukin-11 (rhIL-11) gargle on preventing and treating oral mucositis (OM) after chemotherapy for acute leukemia. METHODS This single-site, prospective, observer-blinded, nonrandomized controlled trial was conducted on 74 patients with acute leukemia, who were divided into the experimental and control groups. The patients in the experimental group were treated with IL-11 gargle, and those in the control group were treated with sodium bicarbonate gargle. We examined the time and severity of oral mucositis, severity and duration of associated pain, healing time of mucositis, effects of OM on eating, and levels of T-cell subset indicators before and after treatment to evaluate the effects of IL-11 treatment. RESULTS The proportion of patients with severe OM was significantly lower in the experimental group than in the control group. Mucositis occurred later in the experimental group compared with the control group. The degree and duration of pain, ulcer healing time, and effects on eating were lower in the experimental group compared with the control group. Following treatment, the levels of all T-cell subset indicators improved in each of the two groups. However, the rate of improvement was significantly higher in the experimental group than in the control group. These differences were statistically significant (P < 0.05). CONCLUSIONS IL-11 gargle reduced the severity of OM after chemotherapy for acute leukemia. Treatment with IL-11 relieved pain, promoted healing, and improved the curative effect of the condition, making it worthy of clinical promotion.

Abstract
Introduction Carbapenem resistant gram-negative bacteria (CRGNB) infection is more and more frequent in patients after hematopoietic stem cell transplantation (HSCT), and the prognosis is very poor. The purpose of this study was to investigate the clinical characteristics and risk factors for mortality with CRGNB infection in HSCT recipients, and to provide useful information for guiding the application of antibiotics and improving the prognosis in the future. Methods Electronic medical records of CRGNB infected patients who underwent HSCT in Xiangya Hospital from January 1, 2015 to June 30, 2022 were collected. At the same time, 1:1 case-control matching was performed according to gender, age and disease type. The epidemiological characteristics and drug resistance of patients with CRGNB infection and non-CRGNB infection were compared. Logistic regression and Cox regression analysis were used to determine the risk factors for CRGNB acquisition and death respectively, and a prediction model of overall survival was constructed by R language. Results and Discussion The crude infection rate of CRGNB in HSCT recipients was 7.42%, and the mortality rate was 47.1%. CRGNB was resistant to most commonly used antibiotics. Time interval from diagnosis to transplantation >180 days (HR=7.886, 95% CI 2.624-23.703, P=0.000), septic shock (HR=6.182, 95% CI 2.605-14.671, P=0.000), platelet count < 20 × 109/L (HR=2.615, 95% CI 1.152-5.934, P=0.022) and total bilirubin > 34.2 μmol/L (HR=7.348, 95% CI 2.966-18.202, P=0.000) at the initial stage of infection were 4 independent risk factors associated with mortality. CRGNB infection has become a serious threat to HSCT recipients. Clinicians should pay high attention to it and actively seek personalized treatment strategies suitable for local medical conditions.

Abstract
Adult acute lymphoblastic leukemia (ALL) is heterogeneous both biologically and clinically. The outcomes of ALL have been improved with the application of children-like regimens and novel agents including immune therapy in young adults. The refractory to therapy and relapse of ALL have occurred in most adult cases. Factors affecting the prognosis of ALL include age and white blood cell (WBC) count at diagnosis. The clinical implications of genetic biomarkers, including chromosome translocation and gene mutation, have been explored in ALL. The interactions of these factors on the prediction of prognosis have not been evaluated in adult ALL. A prognostic model based on clinical and genetic abnormalities is necessary for clinical practice in the management of adult ALL. The newly diagnosed adult ALL patients were divided into the training and the validation cohort at 7:3 ratio. Factors associated with overall survival (OS) were assessed by univariate/multivariate Cox regression analyses and a signature score was assigned to each independent factor. A nomogram based on the signature score was developed and validated. The receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis (DCA) were used to assess the performance of the nomogram model. This study included a total of 229 newly diagnosed ALL patients. Five independent variables including age, WBC, bone marrow (BM) blasts, MLL rearrangement, and ICT gene mutations (carried any positive mutation of IKZF1, CREBBP and TP53) were identified as independent adverse factors for OS evaluated by the univariate, Kaplan-Meier survival and multivariate Cox regression analyses. A prognostic nomogram was built based on these factors. The areas under the ROC curve and calibration curve showed good accuracy between the predicted and observed values. The DCA curve showed that the performance of our model was superior to current risk factors. A nomogram was developed and validated based on the clinical and laboratory factors in newly diagnosed ALL patients. This model is effective to predict the overall survival of adult ALL. It is a simple and easy-to-use model that could efficiently predict the prognosis of adult ALL and is useful for decision making of treatment.

Abstract
Objective: The study aims to explore the efficacy and safety of low-dose chemotherapy combined with tyrosine kinase inhibitor (TKI) as an induction therapy for Philadelphia-chromosomal-positive acute lymphoblastic leukemia (Ph(+) ALL) . Methods: The data of the consecutive newly diagnosed patients with Ph(+) ALL were reviewed. The efficacy and safety of low-dose chemotherapy and conventional-dose chemotherapy combined with TKI were compared. Results: A total of 217 patients with a median age of 38 (10-69) years old were included in this study. 78 patients were in the low-dose chemotherapy group, and 139 patients were in the conventional-dose chemotherapy group. There were no significant differences in the 4-week complete remission (CR) rate (98.7% vs 97.0%, P=0.766) and overall CR rate (100% vs 100%, P=1.000) between the two groups. Multivariate analyses showed that the chemotherapy intensity was not related to the disease-free survival rate and overall survival rate. However, the lower incidence of infection (P=0.017) , the shorter duration of neutropenia (P=0.001) and PLT<20 × 10(9)/L (P=0.057) , and the lower red blood cell transfusion volume (P=0.002) were more common in the low-dose chemotherapy group than in the conventional-dose chemotherapy group. Conclusions: The low-dose chemotherapy is superior to the conventional-dose chemotherapy combined with TKI as induction therapy in Ph(+) ALL with similar efficacy but is safer.

Abstract
OBJECTIVE To evaluate the efficacy and safety of CD19 chimeric antigen receptor (CAR) T cell therapy for patients with B cell acute lymphoblastic leukemia (B-ALL) involving extramedullary relapse. METHODS Fifteen patients with B-ALL involving extramedullary relapse who received CD19 CAR-T cell therapy in the First Affiliated Hospital, Zhejiang University School of Medicine from January 2016 to October 2021 were enrolled in this study. The overall survival and leukemia-free survival of patients were analyzed using Kaplan-Meier curves, and the response of extramedullary lesions in different locations following the CD19 CAR-T cell therapy was observed. Cytokine release syndrome (CRS), hematological toxicity, and immune effector cell-associated neurotoxicity syndrome (ICANS) during CD19 CAR-T cell therapy were analyzed. RESULTS The median follow-up time was 7 (3-71) months, and 11 cases (73.3%) achieved complete response, median duration of complete response was 6 (2-27) months; 3 cases (20.0%) achieved partial response; 1 case (6.7%) got progressive disease. The overall response rate was 93.3% (14/15), and the overall survival rate was 80.0% (12/15) at the end of follow-up. The cumulative incidence of relapse was 40.0% (6/15) and relapse mortality rate was 20.0% (3/15). Until last follow-up date, 9 cases (60.0%) were still in disease-free survival. Among the 15 patients, 13 cases (86.7%) developed cytokine release syndrome (CRS) after cell infusion, including 7 cases with grade 1-2 CRS, 6 cases with grade 3 CRS; 1 case suffered from reversible ICANS; 15 cases (100.0%) developed B cell dysplasia; 12 cases (80.0%) developed severe hematologic adverse reactions; 2 cases (13.3%) had abnormal liver function; 1 case (6.7%) had abnormal renal function; 4 cases (26.7%) developed infection. The adverse reactions mentioned above were well controlled. CONCLUSION CD19 CAR-T cell therapy shows explicit efficacy and controllable adverse reactions for B-ALL patients with extramedullary relapse.
