Two Cases of Tuberculosis Manifesting as Cutaneous Solitary Mass in Patients with Adult T-Cell Leukemia/Lymphoma

Tuberculosis (TB) is a major public health problem worldwide and a large number of fatal cases are still reported. Immunocompetent individuals are naturally susceptible to TB, and immunocompromised patients have a greater risk of infection. Although patients with adult T-cell leukemia/lymphoma (ATL) are in an immunosuppressed condition, there is only one reported case of TB accompanied with ATL in the English- language literature in the field of dermatology. Here, we report two patients with chronic-type ATL infected with TB manifesting as cutaneous solitary masses. Case 1 was a 58-year-old woman diagnosed with lumbar abscess with pulmonary TB. Case 2 was an 84-year-old woman diagnosed with tuberculous lymphadenitis in the left cervical region. It is important to raise the differential diagnosis of TB and perform tissue culture for acid-fast bacilli as well as Interferon-Gamma release assay test when dermatologists encounter mass lesions in patients with ATL.

Adult T-cell leukemia/lymphoma presenting multiple lymphomatous polyposis

Multiple lymphomatous polyposis (MLP) is an unusual form of non-Hodgkin's lymphoma characterized by polyps throughout the gastrointestinal tract. It has been reported that most MLP are observed in cases with mantle cell lymphoma of B-cell type. We herein present a case of a 66-year-old man with adult T-cell leukemia/lymphoma (ATLL). Colonoscopy revealed MLP throughout the colon and histopathological findings of ATLL cell infiltration. The patient died despite combination of chemotherapy. The literature of manifestations of colonic involvement of ATLL isreviewed and the importance of endoscopic evaluation to differentiate ATLL intestinal lesions from opportunistic infectious enterocolitis is discussed.

A novel mouse model of adult T-cell leukemia cell invasion into the spinal cord

Adult T-cell leukemia( ATL) is a mature T-cell malignancy caused by human T-cell leukemia virus type I infection, and 10%-25% of patients show central nervous system( CNS) involvement. CNS involvement significantly reduces survival and there are no effective treatments for CNS involvement. Therefore, an appropriate animal model is required to evaluate the inhibitory effects of novel drugs on the progression of ATL with CNS involvement. Here, we established a mouse model of ATL with CNS involvement using NOD.Cg-Prkdc~ (scid) Il2 rg ^(tm1Wjl)/SzJ mice inoculated with ATL cells intramuscularly in the postauricular region, and these mice showed paraparesis. Of the 10 mice inoculated with ATL cells intramuscularly(I.M.) at 5 weeks of age, 8(80%) showed paraparesis, whereas none of the 10 mice inoculated with ATL cells subcutaneously(S.C.) showed paraparesis. In the I.M. group, PCR detected HTLV-1-specific genes in the thoracic and lumbar vertebrae; however, in the S.C. group, the vertebrae were negative for HTLV-1 genes. Histological analysis revealed a particularly high incidence of tumors, characterized by accumulation of the injected cells, in the thoracic vertebrae of mice in the I.M. group. Tumor cell infiltration was relatively high in the bone marrow. Spinal cord compression caused by invasion of the tumor mass outside the pia mater was observed in the thoracic vertebrae of the spinal cord. In conclusion, we have reported a mouse model of tumor growth with paraparesis that may be used to assess novel therapeutic agents for ATL with CNS involvement.

The Role of Mitochondrial VDAC2 in the Survival and Proliferation of T-Cell Acute Lymphoblastic Leukemia Cells

Background: T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematological malignancy with aberrant T-cell developmental arrest. Individuals with relapsed T-ALL have limited therapeutic alternatives and poor prognosis. The mitochondrial function is critical for the T-cell viability. The voltage-dependent anion channel 2 (VDAC2) in the mitochondrial outer membrane, interacts with pro-apoptotic BCL-2 proteins and mediates the apoptosis of several cancer cell lines. Objective: The aim of the current study is to explore the role of VDAC2 in T-ALL cell survival and proliferation. Methods: Publicly available datasets of RNA-seq results were analyzed for expression of VDAC isoforms and T-ALL cell lines were treated with a VDAC2 small molecular inhibitor erastin. A VDAC2 RNA interference (siRNA) was delivered to T-ALL cell lines using a retroviral vector. Functional assays were performed to investigate the VDAC2 siRNA impacts on cell proliferation, apoptosis and survival of T-ALL cells. Results: Our analysis found a high expression of VDAC2 mRNA in various T-ALL cell lines. Public datasets of T-ALL RNA-seq also showed that VDAC2 is highly expressed in T-ALL (116.2 ± 36.7), compared to control groups. Only two T-ALL cell lines showed sensitivity to erastin (20 μM) after 48 hours of incubation, including Jurkat (IC50 = 3.943 μM) and Molt4 (IC50 = 3.286 μM), while another two T-ALL cells (CUTLL1 and RPMI 8402) had unstable IC50. However, five T-ALL cell lines (LOUCY, CCRF-CEM, P12-ICHI, HPB-ALL, and PEER cells) showed resistance to erastin. On the contrary, all T-ALL cell lines genetically inhibited with VDAC2 siRNA led to more than 80% decrease in VDAC2 mRNA levels, and a Conclusion: VDAC2 is highly expressed in T-ALL cells. The inhibition of VDAC2 significantly decreased cell viability, increased apoptosis, reduced cell proliferation and caused cell cycle sub-G1 arrest of T-ALL cells.

Comparison of the Effects of L-asparaginase and Pegaspargase in the Treatment of Adult Acute Lymphoblastic Leukemia

Objective:To compare the effect of L-asparaginase and pegaspargase in the treatment of adult acute lymphoblastic leukemia.Methods:In this study,96 patients who received treatment at the Shaanxi Provincial People’s Hospital from April 2019 to April 2021 were selected.The control group received L-asparaginase treatment,and the observation group received pegaspargase treatment.The curative effect and adverse reaction rate were compared between the two groups.Results:Comparing the experimental statistical results of the observation and the control groups,it can be concluded that the effect of the former group is better than that of the latter group in terms of clinical curative effect and statistics of adverse reactions.Conclusion:In the treatment of adult acute lymphoblastic leukemia,the application of pegaspargase therapy has a significantly better clinical effect and is worthy of further promotion.

Cutaneous Manifestations and Treatment Advances of Adult T-Cell Leukemia/Lymphoma

Adult T-cell leukemia/lymphoma(ATLL)is an aggressive peripheral T-cell lymphoma caused by the human T lymphotropic virus type-1.The skin is affected in approximately half of ATLL patients,and skin lesions may be the first manifestation of the disease.The skin lesions of ATLL are polymorphous,and depend on the type of skin eruption,which makes it possible for doctors to predict the prognosis of the disease based on the characteristics of skin lesions.In this review article,we describe the clinical manifestations and histopathological patterns of skin lesions in ATLL,focus on its diagnostic and prognostic significance,and also summarize the advances in the treatment of ATLL.

Resveratrol Induces Apoptosis and Autophagy in T-cell Acute Lymphoblastic Leukemia Cells by Inhibiting Akt/mTOR and Activating p38-MAPK

Objective To explore the effects of resveratrol-induced apoptosis and autophagy in T-cell acute lymphoblastic leukemia （T-ALL） cells and potential molecular mechanisms. Methods The anti-proliferation effect of resveratrol-induced, apoptosis and autophagy on T-ALL cells were detected by using MTI- test, immunofluorescence, electronic microscope, and flow cytometry, respectively. Western blotting was performed for detecting changes of apoptosis-associated proteins, cell cycle regulatory proteins and state of activation of Akt, mTOR, p70S6K, 4E-BP1, and p38-MAPK. Results Resveratrol inhibited the proliferation and dose and time-dependent manner. It also induced cyclin-dependent kinase （CDK） inhibitors p21 and induced apoptosis and autophagy in T-ALL cells in a cell cycle arrest at G0/G1 phase via up regulating p27 and down regulating cyclin A and cyclin D1. Western blotting revealed that resveratrol significantly decreased the expression of antiapoptotic proteins （Mcl-1 and Bcl-2） and increased the expression of proapoptotic proteins （Bax, Bim, and Bad）, and induced cleaved-caspase-3 in a time-dependent manner. Significant increase in ratio of LC3-11/LC3-1 and Beclin 1 was also detected. Furthermore, resveratrol induced significant dephosphorylation of Akt, mTOR, p70S6K, and 4E-BP1, but enhanced specific phosphorylation of p38-MAPK which could be blocked by SB203580. When autophagy was suppressed by 3-MA, apoptosis in T-ALL cells induced by resveratrol was enhanced. Conclusion Our findings have suggested that resveratrol induces cell cycle arrest, apoptosis, and autophagy in T-ALL cells through inhibiting Akt/mTOR/p7OS6K/4E-BP1 and activating p38-MAPK signaling pathways. Autophagy might play a role as a self-defense mechanism in T-ALL cells treated by resveratrol. Therefore, the reasonable inhibition of autophagy in T-ALL cells may serve as a promising strategy for resveratrol induced apoptosis and can be used as adjuvant chemotherapy for T-ALL.

Role of Ikaros in T-cell acute lymphoblastic leukemia

Ikaros is a zinc finger transcriptional regulator encoded by the Ikzf1 gene.Ikaros displays crucial functions in the hematopoietic system and its loss of function has been linked to the development of lymphoid leukemia.In particular,Ikaros has been found in recent years to be a major tumor suppressor involved in human B-cell acute lymphoblastic leukemia.Its role in T-cell leukemia,however,has been more controversial.While Ikaros deficiency appears to be very frequent in murine T-cell leukemias,loss of Ikaros appears to be rare in human T-cell acute lymphoblastic leukemia (T-ALL).We review here the evidence linking Ikaros to T-ALL in mouse and human systems.

MicroRNA-145-3p suppresses the malignant behaviors of T-cell acute lymphoblastic leukemia Jurkat cells via inhibiting the NF-kappaB signaling pathway

T-cell acute lymphoblastic leukemia(T-ALL)is a hematological tumor caused by the malignant transformation of immature T-cell progenitor cells.Emerging studies have stated that microRNAs(miRNAs)may play key roles in T-ALL progression.This study aimed to investigate the roles of miR-145-3p in T-ALL cell proliferation,invasion,and apoptosis with the involvement of the nuclear factor-kappaB(NF-κB)signaling pathway.T-ALL Jurkat cells were harvested,and the expression of miR-145-3p and NF-κB-p65 was measured.Gain-and loss-of-functions of miR-145-3p and NF-κB-p65 were performed to identify their roles in the biological behaviors of Jurkat cells,including proliferation,apoptosis,and invasion.Consequently,the current study demonstrated that miR-145-3p was down-regulated while NF-κB-p65 was up-regulated in Jurkat cells.miR-145-3p directly bound to the 3’untranslated region of NF-κB-p65.Over-expression of miR-145-3p inhibited Jurkat cell proliferation,invasion,and resistance to apoptosis,while over-expression of NF-κB-p65 presented opposite trends.Co-transfection of miR-145-3p and NF-κB-p65 promoted the malignant behaviors of Jurkat cells compared to miR-145-3p transfection alone,while it reduced these behaviors of Jurkat cells compared to NF-κB-p65 transfection alone.Taken together,this study provided evidence that miR-145-3p could suppress proliferation,invasion,and resistance to the death of T-ALL cells via inactivating the NF-κB signaling pathway.

Predictive Value of Dynamic Peri-Transplantation MRD Assessed By MFC Either Alone or in Combination with Other Variables for Outcomes of Patients with T-Cell Acute Lymphoblastic Leukemia

We performed a retrospective analysis to investigate dynamic peri-hematopoieticstem cell transplantation(HSCT)minimal/measurable residual disease(MRD)on outcomes inpatients with T-cell acute lymphoblastic leukemia(T-ALL).A total of 271 patients were enrolledand classified into three groups:unchanged ncgative MRD pre-and post-HSCT group(group A),post-MRD non-increase group(group B),and post-MRD increase group(group C).The patientsin group B and group C experienced a higher cumulative incidence of relapse(CIR)(42%vs.71%vs.16%,P<0.001)and lower leukemia-free survival(LFS)(46%vs.21%vs.70%,P<0.001)andoverall survival(OS)(50%vs.28%vs.72%,P<0.001)than in group A,but there was no significantdifference in non-relapse mortality(NRM)among three groups(14%vs.12%vs.8%,P=0.752).Multivariate analysis showed that dynamic peri-HSCT MRD was associated with CIR(HR=2.392,95%CI,1.816-3.151,P<0.001),LFS(HR=1.964,95%CI,1.546-2.496,P<0.001)and os(HR=1.731,95%CI,1.348-2.222,P<0.001).We also established a risk scoring system based ondynamic peri-HSCT MRD combined with remission status pre-HSCT and onsct of chronic graft-versus-host disease(GVHD).This risk scoring system could better distinguish ClR(c=0.730)thanthat for pre-HSCT MRD(c=0.562),post-HSCT MRD(c=0.616)and pre-and post-MRD dynamics(c=0.648).Our results confirm the outcome predictive value of dynamic peri-HSCT MRD eitheralone or in combination with other variables for patients with T-ALL.

Metachronous mixed cellularity classical Hodgkin’s lymphoma and T-cell leukemia/lymphoma: A case report

BACKGROUND The development of peripheral T-cell lymphoma(PTCL)after chemotherapy for Hodgkin’s lymphoma(HL)is rare,and highly aggressive TCL/leukemia has not been reported to date.The relationship between HL and PTCL needs further exploration to understand the pathogenesis of metachronous lymphoma(ML)and find effective treatment options.We report a patient with ML,whose biopsy of a right cervical lymph node initially confirmed classical HL(CHL).CASE SUMMARY We report a patient with ML,whose biopsy of a right cervical lymph node initially confirmed CHL,with typical reed–sternberg cells expressing CD30 and PAX-5.T-cell leukemia/lymphoma occurred 3 years after treatment,and a lymph node biopsy at the onset confirmed PTCL,nonspecific type,expressing CD3,CD4 and CD8.The patient was treated with standard doses of chemotherapy,programmed cell death-ligand 1 monoclonal antibody,and chidamide,all of which failed to achieve complete remission.The patient was diagnosed with refractory state,and eventually died of leukocyte stasis.CONCLUSION The accuracy of the diagnosis needs to be confirmed when chemotherapeutic drugs are not effective.

Adult Acute T Cell Leukemia Presenting as Acute Renal Failure, Parotid Swelling and Loss of Vision

A rare case of T cell acute lymphoblastic leukemia presenting with loss of vision, parotid swelling, hematuria and acute renal failure has been presented in a 40-year-old male. Acute T cell Lymphoblastic Leukemia should also be kept in differential diagnosis of hematuria, acute renal failure and loss of vision.

Treatment for CD57-negativeγδT-cell large granular lymphocytic leukemia with pure red cell aplasia:A case report

BACKGROUND T-cell large granular lymphocytic leukemia(T-LGLL)is a rare type of aplastic anemia with diverse clinical manifestations.Concomitant diseases are often present at the first manifestation.We describe the treatment of a patient with CD57-negativeγδT-LGLL with pure red cell aplasia(PRCA).CASE SUMMARY A 34-year-old woman with a 20-year history of anemia visited our hospital owing to severe dizziness and was admitted.Her condition was diagnosed as CD57-negativeγδT-LGLL with PRCA through bone marrow cytology,bone marrow pathology,bone marrow flow cytometry,bone marrow multiplex polymerase chain reaction combined with fluorescent fragment analysis,and other tests.Treatment with prednisone,methotrexate,and subcutaneous erythropoietin did not significantly change her hemoglobin level.After treatment with oral cyclophosphamide for 3 mo,her hemoglobin level increased to approximately 100 g/L.After 5 mo of treatment,the patient could perform activities of daily living independently.CONCLUSION The treatment of CD57-negativeγδT-LGLL with PRCA with cyclophosphamide helps to improve prognosis.

Secondary peripheral T-cell lymphoma and acute myeloid leukemia after Burkitt lymphoma treatment:A case report

BACKGROUND Multiple primary cancer refers to more than one synchronous or sequential cancer in the same individual.Multiple primary cancer always presents as solid cancer or acute myeloid leukemia(AML)secondary to lymphoma.Here,we report a rare case of secondary peripheral T-cell lymphoma and AML after Burkitt lymphoma treatment.CASE SUMMARY A 54-year-old female patient was admitted to our hospital complaining of edema on her left lower limb.Physical examination revealed multiple superficial lymphadenectasis on her neck and pelvis.Color ultrasonography examination showed multiple uterine fibroids and a solid mass at the lower left side of the abdomen.Pathological biopsy revealed Burkitt lymphoma.After three hyper-CVAD(A+B)regimens,she achieved complete remission.Two years later,lymphadenectasis reoccurred.A relevant biopsy confirmed the diagnosis of peripheral T-cell lymphoma,which was accompanied by gastrointestinal invasion and hemocytopenia.Meanwhile,bone marrow examination revealed AML.On the second day of scheduled treatment,she developed gastrointestinal bleeding,peptic ulcers,and hemorrhagic shock and was critically ill.She was then discharged from the hospital due to financial concerns.CONCLUSION This is the first report of secondary peripheral T-cell lymphoma and AML after Burkitt lymphoma treatment with heterochronous and synchronal multiple primary cancers.

Current assessment and management of measurable residual disease in patients with acute lymphoblastic leukemia in the setting of CAR-T-cell therapy

Chimeric antigen receptor(CAR)-modified T-cell therapy has achieved remarkable success in the treatment of acute lymphoblastic leukemia(ALL).Measurable/minimal residual disease(MRD)monitoring plays a significant role in the prognostication and management of patients undergoing CAR-T-cell therapy.Common MRD detection methods include flow cytometry(FCM),polymerase chain reaction(PCR),and next-generation sequencing(NGS),and each method has advantages and limitations.It has been well documented that MRD positivity predicts a poor prognosis and even disease relapse.Thus,how to perform prognostic evaluations,stratify risk based on MRD status,and apply MRD monitoring to guide individual therapeutic decisions have important implications in clinical practice.This review assesses the common and novel MRD assessment methods.In addition,we emphasize the critical role of MRD as a prognostic biomarker and summarize the latest studies regarding MRD-directed combination therapy with CAR-T-cell therapy and allogeneic hematopoietic stem cell transplantation(allo-HSCT),as well as other therapeutic strategies to improve treatment effect.Furthermore,this review discusses current challenges and strategies for MRD detection in the setting of disease relapse after targeted therapy.

Multi-omics integration reveals potential stage-specific druggable targets in T-cell acute lymphoblastic leukemia

T-cell acute lymphoblastic leukemia(T-ALL),a heterogeneous hematological malignancy,is caused by the developmental arrest of normal T-cell progenitors.The development of targeted therapeutic regimens is impeded by poor knowledge of the stage-specific aberrances in this disease.In this study,we performed multi-omics integration analysis,which included mRNA expression,chromatin accessibility,and gene-dependency database analyses,to identify potential stage-specific druggable targets and repositioned drugs for this disease.This multi-omics integration helped identify 29 potential pathological genes for T-ALL.These genes exhibited tissue-specific expression profiles and were enriched in the cell cycle,hematopoietic stem cell differentiation,and the AMPK signaling pathway.Of these,four known druggable targets(CDK6,TUBA1A,TUBB,and TYMS)showed dysregulated and stage-specific expression in malignant T cells and may serve as stage-specific targets in T-ALL.The TUBA1A expression level was higher in the early T cell precursor(ETP)-ALL cells,while TUBB and TYMS were mainly highly expressed in malignant T cells arrested at the CD4 and CD8 double-positive or single-positive stage.CDK6 exhibited a U-shaped expression pattern in malignant T cells along the naıve to maturation stages.Furthermore,mebendazole and gemcitabine,which target TUBA1A and TYMS,respectively,exerted stage-specific inhibitory effects on T-ALL cell lines,indicating their potential stage-specific antileukemic role in T-ALL.Collectively,our findings might aid in identifying potential stage-specific druggable targets and are promising for achieving more precise therapeutic strategies for T-ALL.

Retrospective study of a cohort of adult patients with hematological malignancies in a tropical area

AIM: To review the characteristics of hematological malignancies in tropical areas, and to focus on the specific difficulties regarding their management. METHODS: This is a retrospective narrative review of cases of patients with hematological malignancies. All medical files of patients with malignant disease whose treatment was coordinated by the HematoOncology service of the Cayenne Hospital in French Guiana between the 1st of January 2010 and the 31 st of December 2012 were reviewed. Clinical data were extracted from the medical files and included: Demographic data, comorbidities, serological status for human immunodeficiency virus, human T-lymphotropic virus 1(HTLV1), hepatitis B virus and hepatitis C virusinfections, cytology and pathology diagnoses, disease extension, treatment, organization of disease management, and follow-up. The subgroup of patients with hematological malignancies and virus-related malignancies were reviewed. Cases involving patients with Kaposi sarcoma, and information on solid tumor occurrence in virus-infected patients in the whole patient population were included. Since the data were rendered anonymous, no informed consent was obtained from the patients for this retrospective analysis. Data were compiled using EXCEL&#174; software, and the data presentation is descriptive only. The references search was guided by the nature of the data and discussion. RESULTS: In total, the clinical files of 594 patients(pts) were reviewed. Hematological malignancies were observed in 87 patients, and Kaposi sarcoma in 2 patients. In total, 70 patients had a viral infection, and 34 of these also had hematological malignancies. The hematological diagnoses were: Multiple myeloma in 27 pts, lymphoma(L) in 43 pts, myeloproliferative disorders in 17 pts and Kaposi sarcoma in two patients. The spectrum of non-Hodgkin lymphomas(NHL) was: Burkitt L(1 pt), follicular L(5 pts), chronic lymphocytic leukemia(5 pts), high-grade NHL(9 pts), mucosa-associated lymphoid tissue NHL(4 pts), T-cell lymphoma(4 pts), Adult T-cell lymphoma-leukemia(ATL)/lymphoma/leukemia(12 pts); three patients had Hodgkin disease. The spectrum of myeloproliferative diseases was: Chronic myelogenous leukemia(8 pts), thrombocytemia(5 pts) and acute leukemia(4 pts). There were no polycythemia vera, myelosclerosis, and myelodysplastic diseases. This appears to be due to bias in the recruitment process. The most important observations were: The specificity of HTLV1- related ATL malignancies, and the high incidence of virus infections in patients with hematological malignancies. Further, we noted several limitations regarding the treatment and organization of disease management. These were not related to the health care organization, but were due to a lack of board-certified hematooncology specialists, a lack of access to diagnostic tools(e.g., cytogenetic and molecular diagnosis, imaging techniques), the unavailability of radiotherapy, and the physical distance from mainland France. Yet the geography and cultures of the country also contributed to the encountered difficulties. These same limitations are seen in tropical countries with low and intermediate household incomes, but they are amplified by economic, social, and cultural issues. Thus, there is often little access to diagnostic procedures, adequate clinical management, and an unavailability of suitable medical treatments. Programs have been developed to establish centers of excellence, training in pathology diagnosis, and to provide free access to treatment.CONCLUSION: Management of hematological malignancies in tropical areas requires particular skills regarding specific features of these diseases and in terms of the affected populations, as well as solid public health policies.

Breathing adapted radiation therapy for leukemia relapse in the breast: A case report

BACKGROUND Infiltration of the breast by leukemic cells is uncommon but may manifest as an oncological emergency requiring prompt management.Extramedullary relapse of T-cell acute lymphoblastic leukemia(T-ALL)within the breast is exceedingly rare and there is paucity of data in the literature regarding this entity.No consensus exists on management of isolated extramedullary breast relapses of T-ALL.Herein,we report a case of isolated extramedullary breast relapse of T-ALL treated with breathing adapted radiation therapy(BART)using the active breathing control(ABC)system.CASE SUMMARY The patient was a 33-year-old female with diagnosis of T-ALL.She received intensive systemic chemotherapy that resulted in complete remission of her disease,and then underwent allogeneic hematopoietic stem cell transplantation.After a 15 mo period without symptoms and signs of progression,the patient presented with palpable masses in both breasts.She complained from severe pain and swelling of the breasts.Imaging workup showed bilateral breast lesions,and diagnosis of breast infiltration by leukemic cells was confirmed after immunohistopathological evaluation.The patient suffering from severe pain,discomfort,and swelling of both breasts due to leukemic infiltration was referred to the Radiation Oncology Department for symptomatic palliation.Whole breast irradiation was delivered to both breasts of the patient with BART using the ABC system.The patient had complete resolution of her symptoms after treatment with BART.CONCLUSION BART with the ABC system resulted in complete resolution of the patient’s symptoms due to leukemic infiltration of both breasts with T-ALL.This contemporary treatment technique should be preferred for radiotherapeutic management of patients with leukemic infiltration of the breasts to achieve effective symptomatic palliation.
