Abstract
CONTEXT.— Unlike B-cell acute lymphoblastic leukemia/lymphoma (ALL/LBL), there have been few therapeutic advances in T-cell ALL (T-ALL)/LBL, an aggressive ALL/LBL subtype. OBJECTIVE.— To perform a focused tissue array study to elucidate tumor markers of therapeutic potential in T-ALL/LBL. DESIGN.— Using immunohistochemistry, we evaluated expression of leukemic antigens of interest, specifically CC-chemokine receptor 4 (CCR4), among others, on available remnant diagnostic material, including tumor tissue slides obtained from formalin-fixed, paraffin-embedded preserved tissues. RESULTS.— Our analysis identified, for the first time, expression of CCR4 in T-ALL/LBL in 11 of 27 cases (40.7%) and confirmed common expression of BCL2, CD38, and CD47, as reported previously. We also identified the expression of CD123 in 4 of 26 cases (15.4%), whereas BCL6 and PDL1 were expressed in a small number of T-ALL/LBL cases. The potential novel target CCR4 was significantly more common in the Pre/Pro-T immunophenotypic subtype, 6 of 9 (66.7%, P = .01). No additional differences in clinical and epidemiologic variables were noted among positive or negative CCR4 cases. CONCLUSIONS.— These findings support preclinical and clinical testing of therapies targeting CCR4, CD47, BCL2, CD38, and CD123 in T-ALL/LBL, and may help guide the development of targeted clinical trials in T-ALL/LBL, a rare disease in urgent need of novel therapies.

Abstract
The NOTCH-Delta-HES signaling cascade is regarded as a double-edged sword owing to its dual tumor-suppressor and oncogenic roles, in different cellular environments. In the T-cells, it supports leukemogenesis by promoting differentiation while in B-cells, it controls leukemogenesis by inhibiting early differentiation/inducing growth arrest in the lead to apoptosis. The present study was undertaken to assess if this bi-faceted behavior of NOTCH family can be exploited as a diagnostic biomarker or subtype classifier of acute lymphoblastic leukemia (ALL). In this pursuit, expression of seven NOTCH cascade genes was analyzed in bone marrow (BM) biopsy and blood plasma (BP) of pediatric ALL patients using quantitative PCR (qPCR). Further, promoter DNA methylation status of the differentially expressed genes (DEGs) was assessed by methylation-specific qMSP and validated through bisulphite amplicon sequencing. Whereas hypermethylation of JAG1, DLL1, and HES-2, HES-4, and HES-5 was observed in all patients, NOTCH3 was found hypermethylated specifically in Pre-B ALL cases while DLL4 in Pre-T ALL cases. Aberrant DNA methylation strongly correlated with downregulated gene expression, which restored at complete remission stage as observed in "follow-up/post-treatment" subjects. The subtype-specific ROC curve analysis and Kaplan-Meier survival analysis predicted a clinically applicable diagnostic and prognostic potential of the panel. Moreover, the logistic regression model (Pre-B vs Pre-T ALL) was found to be the best-fitted model (McFadden's R2 = 0.28, F1 measure = 0.99). Whether analyzed in BM-aspirates or blood plasma, the NOTCH epigenetic signatures displayed comparable results (p < 0.001), advocating the potential of NOTCH-Delta-HES cascade, as a subtype classifier, in minimally invasive diagnosis of ALL.

Abstract
Philadelphia chromosome-positive (Ph+) T-cell acute lymphoblastic leukemia (T-ALL) is a rare and aggressive type of acute leukemia. The Philadelphia chromosome is the hallmark of chronic myeloid leukemia (CML). The differentiation between Ph+ T-ALL and T-cell lymphoblastic crisis of CML may be problematic in some cases. Here, we report a rare case of de novo Ph+ T-ALL that presented a diagnostic challenge. The overall clinical, immunophenotypic, cytogenetic, and xenotransplantation results suggest a diagnosis of Ph+ T-ALL. The patient was treated with induction chemotherapy including imatinib followed by haploidentical stem cell transplantation and achieved complete remission.

Abstract
Distinguishing T-lymphoblastic leukemia/lymphoma (T-ALL/T-LBL) from thymomas (especially B1 or B2 type) can be challenging particularly in limited trucut biopsy material where appreciating architecture is difficult or the background epithelial component does not provide tangible evidence for definite diagnosis. As a pathologist, it is important to accurately diagnose these neoplasms because they have entirely distinct management protocols. Recent studies have reported that LIM Domain Only 2 (LMO2) is expressed in neoplastic lymphoblasts of T-ALL/T-LBL and is absent in thymocytes of normal thymuses or thymomas. An observational study was done to test the sensitivity and specificity of LMO2 in differentiating neoplastic lymphoblasts from thymocytes of thymomas/normal thymuses. Our study showed that LMO2 had sensitivity of 70% and specificity of 100% in diagnosing LBL. None of the thymomas (B1 or B2 type) showed expression of LMO2 in the neoplastic cells. LMO2 is a reliable marker of transformed T-cell precursors and should be routinely included in immunohistochemical panel when evaluating thymic/mediastinal neoplasms.

Abstract
T-lineage acute lymphoblastic leukemia (T-ALL) accounts for about 15% of pediatric and about 25% of adult ALL cases. Minimal/measurable residual disease (MRD) assessed by flow cytometry (FCM) is an important prognostic indicator for risk stratification. In order to assess the MRD a limited number of antibodies directed against the most discriminative antigens must be selected. We propose a pipeline for evaluating the influence of different markers for cell population classification in FCM data. We use linear support vector machine, fitted to each sample individually to avoid issues with patient and laboratory variations. The best separating hyperplane direction as well as the influence of omitting specific markers is considered. Ninety-one bone marrow samples of 43 pediatric T-ALL patients from five reference laboratories were analyzed by FCM regarding marker importance for blast cell identification using combinations of eight different markers. For all laboratories, CD48 and CD99 were among the top three markers with strongest contribution to the optimal hyperplane, measured by median separating hyperplane coefficient size for all samples per center and time point (diagnosis, Day 15, Day 33). Based on the available limited set tested (CD3, CD4, CD5, CD7, CD8, CD45, CD48, CD99), our findings prove that CD48 and CD99 are useful markers for MRD monitoring in T-ALL. The proposed pipeline can be applied for evaluation of other marker combinations in the future.

Abstract
The early thymic precursor (ETP) immunophenotype was previously reported to confer poor outcome in T-cell acute lymphoblastic leukemia (T-ALL). Between 2009 and 2014, 1256 newly diagnosed children and young adults enrolled in Children's Oncology Group (COG) AALL0434 were assessed for ETP status and minimal residual disease (MRD) using flow cytometry at a central reference laboratory. The subject phenotypes were categorized as ETP (n = 145; 11.5%), near-ETP (n = 209; 16.7%), or non-ETP (n = 902; 71.8%). Despite higher rates of induction failure for ETP (6.2%) and near-ETP (6.2%) than non-ETP (1.2%; P < .0001), all 3 groups showed excellent 5-year event-free survival (EFS) and overall survival (OS): ETP (80.4% ± 3.9% and 86.8 ± 3.4%, respectively), near-ETP (81.1% ± 3.3% and 89.6% ± 2.6%, respectively), and non-ETP (85.3% ± 1.4% and 90.0% ± 1.2%, respectively; P = .1679 and P = .3297, respectively). There was no difference in EFS or OS for subjects with a day-29 MRD <0.01% vs 0.01% to 0.1%. However, day-29 MRD ≥0.1% was associated with inferior EFS and OS for patients with near-ETP and non-ETP, but not for those with ETP. For subjects with day-29 MRD ≥1%, end-consolidation MRD ≥0.01% was a striking predictor of inferior EFS (80.9% ± 4.1% vs 52.4% ± 8.1%, respectively; P = .0001). When considered as a single variable, subjects with all 3 T-ALL phenotypes had similar outcomes and subjects with persistent postinduction disease had inferior outcomes, regardless of their ETP phenotype. This clinical trial was registered at AALL0434 as #NCT00408005.

Abstract
BACKGROUND Despite improvements in survival for children with T-cell acute lymphoblastic leukemia and lymphoma (T-ALL/LLy), morbidity remains high. However, data are lacking regarding comprehensive descriptions of clinically relevant adverse events (AEs) experienced during early intensive chemotherapy. PROCEDURE This single-institution retrospective study evaluated children aged 1-21 years with T-ALL/T-LLy diagnosed from 2010 to 2020. Physician chart abstraction identified and graded 20 clinically relevant AEs. AE rates were analyzed by T-ALL or LLy, minimal residual disease status, induction steroid, and use of antimicrobial prophylaxis. Statistical comparisons used the Kruskal-Wallis test (continuous variables) and Chi-square or Fisher's exact test (categorical variables). RESULTS The cohort included 120 patients (T-ALL: 88; T-LLy: 32). Most patients experienced AEs during induction (85 out of 120; 70.8%) and consolidation (89 out of 111; 80.2%). Nonsepsis infection was common in induction (26 out of 120; 21.7%) and consolidation (35 out of 111; 31.5%). Patients treated with dexamethasone during induction had significantly higher rates of nonsepsis infection and/or sepsis during consolidation than those who received prednisone (p < .01). CONCLUSIONS Clinically significant AEs are extremely common during induction and consolidation therapy for patients with T-ALL/LLy. Infectious AEs are particularly prevalent. These results can inform conversations with patients and families and aid in the development of toxicity-related aims in the next generation of, prospective clinical trials in T-ALL/LLy.

Abstract
BACKGROUND Mixed phenotype acute leukemia (MPAL), a rare subgroup of leukemia characterized by blast cells with myeloid and lymphoid lineage features, is difficult to diagnose and treat. A better characterization of MPAL is essential to understand the subtype heterogeneity and how it compares with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). Therefore, we performed single-cell RNA sequencing (scRNAseq) on pediatric MPAL bone marrow (BM) samples to develop a granular map of the MPAL blasts and microenvironment landscape. METHODS We analyzed over 40,000 cells from nine pediatric MPAL BM samples to generate a single-cell transcriptomic landscape of B/myeloid (B/My) and T/myeloid (T/My) MPAL. Cells were clustered using unsupervised single-cell methods, and malignant blast and immune clusters were annotated. Differential expression analysis was performed to identify B/My and T/My MPAL blast-specific signatures by comparing transcriptome profiles of MPAL with normal BM, AML, and ALL. Gene set enrichment analysis (GSEA) was performed, and significantly enriched pathways were compared in MPAL subtypes. RESULTS B/My and T/My MPAL blasts displayed distinct blast signatures. Transcriptomic analysis revealed that B/My MPAL profile overlaps with B-ALL and AML samples. Similarly, T/My MPAL exhibited overlap with T-ALL and AML samples. Genes overexpressed in both MPAL subtypes' blast cells compared to AML, ALL, and healthy BM included MAP2K2 and CD81. Subtype-specific genes included HBEGF for B/My and PTEN for T/My. These marker sets segregated bulk RNA-seq AML, ALL, and MPAL samples based on expression profiles. Analysis comparing T/My MPAL to ETP, near-ETP, and non-ETP T-ALL, showed that T/My MPAL had greater overlap with ETP-ALL cases. Comparisons among MPAL subtypes between adult and pediatric samples showed analogous transcriptomic landscapes of corresponding subtypes. Transcriptomic differences were observed in the MPAL samples based on response to induction chemotherapy, including selective upregulation of the IL-16 pathway in relapsed samples. CONCLUSIONS We have for the first time described the single-cell transcriptomic landscape of pediatric MPAL and demonstrated that B/My and T/My MPAL have distinct scRNAseq profiles from each other, AML, and ALL. Differences in transcriptomic profiles were seen based on response to therapy, but larger studies will be needed to validate these findings.

Abstract
Molecular analysis is the hallmark of T-cell acute lymphoblastic leukemia (T-ALL) categorization. Several T-ALL sub-groups are well recognized based on the aberrant expression of specific transcription factors. This recently resulted in the implementation of eight provisional T-ALL entities into the novel 2022 International Consensus Classification, albeit not into the updated World Health Organization classification system. Despite this extensive molecular characterization, cytogenetic analysis remains the backbone of T-ALL diagnosis in many countries as chromosome banding analysis and fluorescence in situ hybridization are relatively inexpensive techniques to obtain results of diagnostic, prognostic and therapeutic interest. Here, we provide an overview of recurrent chromosomal abnormalities detectable in T-ALL patients and propose guidelines regarding their detection. By referring in parallel to the more general molecular classification approach, we hope to offer a diagnostic framework useful in a broad clinical genetic setting.

Abstract
BACKGROUND Acute lymphoblastic leukemia (ALL) encompasses a group of lymphoid neoplasms that morphologically and immunophenotypically resemble B-lineage and T-lineage precursor cells. Our objective is to describe the immunophenotypic aspects of acute lymphoblastic leukemia (All) diagnosed by flow cytometry at the hematology laboratory of IBN ROCHD University Hospital Center and to compare them with those reported in other series. METHODS This is a descriptive study over a period from August 2016 to October 2021, during a 5 year-and-2-month period. Immunophenotyping was performed at the flow cytometry unit on a Beckman-Coulter with 6 colors and 2 lasers in the hematology laboratory of the same hospital and data was collected retrospectively from the patients' files, their medical prescription files, kalisil software, and a data collection form we have established. RESULTS The 440 patients had ages ranging from 1 month to 76 years, with a median of 9.5 years and the overall male-to-female ratio was 1.44. The immunological subtyping revealed that 82.5% of cases were B-ALL and 17.5% were T-ALL; of these B-ALL cases 230 (63.36%) were children (range: 0.1 - 15 years) and 134 (36.91%) were adults (range: 16 - 76 years); T-ALL were distributed in both age groups, 49 cases (37.7%) were children (range: 2 - 15 years) and 28 (21.56%) were adults (range: 18 - 63 years). All patients presented at least one abnormal blood count; thrombocytopenia has been observed in 89.4% of cases, anemia in 86.5% of cases, hyperleukocytosis in 79.8% of cases, leukopenia in 10.6% of cases, and pancytopenia in 4.8% of cases. The frequency of B-cell markers in B-ALL was found to be 363 (100%) for CD19, 323 (88.94%) for CD10, 290 (80%) for CD79a, and 73 (20%) for CD20. CD34 expression was found in 73 (20%) cases of B-ALL. HLA-DR was found in 54 (15%) cases, while TdT was found in 43 (13%) cases. Aberrant expression of myeloid antigens was found in 94 (26%) cases of B-ALL. Among T-ALL, the positivity of CD3 and CD7 was 100% (77 cases), while CD5 was positive in 58 (75%) cases. CD34 expression was found in only 19 cases of T-ALL. CD4 and CD8 expression was checked in only 9 adult patients and 4 pediatric cases. Out of them, 77.82% of cases were negative for both CD4 and CD8. CD4 and CD8 double positivity was seen in only 11.1% of cases, and 22.4% of cases showed either CD4 or CD8 positivity. CONCLUSIONS We concluded that our study was similar to reports in the Americas and Europe, and it was the first large one that describes the immunophenotypic profile of ALL in the Moroccan population.

Abstract
Chronic myelogenous leukemia at blast crisis with a T-cell phenotype (T-ALL CML-BC) at diagnosis, without any prior history of CML is extremely rare. After the introduction of tyrosine kinase inhibitors (TKIs), CML patients have a median survival comparable to general population and accelerated/blast crisis are rarely encountered. Most CML patients (80%) transform into acute myeloid leukemia and the rest into B-ALL. Anecdotal cases of Ph+ T-ALL, either de novo or in the context of CML-BC have been reported. Left shift in the blood, the presence of splenomegaly/extramedullary infiltration and the occurrence of BCR::ABL1 rearrangement in both the blastic population, as well as in the myeloid cell compartment are key points in differentiating de novo Ph+ T-ALL from T-ALL CML-BC. The latter is a rare entity, characterized by extramedullary disease, p210 transcript and clonal evolution. Lack of preceding CML does not rule out the diagnosis of T-ALL CML-BC. Prompt TKI treatment with ALL-directed therapy followed by allogeneic stem cell transplantation may offer long-term survival in this otherwise poor prognosis entity. In this paper, we describe a patient with T-ALL CML-BC at presentation, still alive 51 months after diagnosis and we offer a review of the literature on this rare subject. All clinical and laboratory features are provided in order to distinguish de novo Ph+ T-ALL from T-ALL CML-BC, underscoring the prognostic and therapeutic significance of such a differentiation.

Abstract
A high index of suspicion of acute leukemia in infants presenting with atypical clinical and laboratory features is of paramount importance to avoid the delay in diagnosis, and treatment of this rare, yet extremely aggressive entity. We report a case of a 10 months infant presenting with a one-month history of fever and restlessness along with complete blood count (CBC) findings of bicytopenia, borderline leukocytosis, leucoerythroblastic picture, and reactive lymphocytes. Considering infection, the patient was kept on antibiotics and symptomatic treatment. However, the persistence of findings led to bone marrow aspirate which revealed T-cell acute lymphoblastic leukemia (T-ALL) on flow cytometry. Infant ALL is almost B cell phenotype and T-ALL is hardly ever reported. Knowledge and recognition of these cases can help to improve awareness regarding consideration of this rare phenotype of leukemia irrespective of clinical presentation and age of the patient. Key Words: Acute lymphoblastic leukemia, Infant leukemia, Flow cytometry.

Abstract
T-cell acute lymphoblastic leukemias (T-ALL) represent 15% of pediatric and 25% of adult ALL. Since they have a particularly poor outcome in relapsed/refractory cases, identifying prognosis factors at diagnosis is crucial to adapting treatment for high-risk patients. Unlike acute myeloid leukemia and BCP ALL, chromosomal rearrangements leading to chimeric fusion-proteins with strong prognosis impact are sparsely reported in T-ALL. To address this issue an RT-MPLA assay was applied to a consecutive series of 522 adult and pediatric T-ALLs and identified a fusion transcript in 20% of cases. PICALM-MLLT10 (4%, n = 23), NUP214-ABL1 (3%, n = 19) and SET-NUP214 (3%, n = 18) were the most frequent. The clinico-biological characteristics linked to fusion transcripts in a subset of 235 patients (138 adults in the GRAALL2003/05 trials and 97 children from the FRALLE2000 trial) were analyzed to identify their prognosis impact. Patients with HOXA trans-deregulated T-ALLs with MLLT10, KMT2A and SET fusion transcripts (17%, 39/235) had a worse prognosis with a 5-year EFS of 35.7% vs 63.7% (HR = 1.63; p = 0.04) and a trend for a higher cumulative incidence of relapse (5-year CIR = 45.7% vs 25.2%, HR = 1.6; p = 0.11). Fusion transcripts status in T-ALL can be robustly identified by RT-MLPA, facilitating risk adapted treatment strategies for high-risk patients.

Abstract
OBJECTIVES We evaluated MYC and p53 expression, TP53 aberration, their relationship, and their impact on overall survival (OS) in acute lymphoblastic leukemia (ALL)/lymphoblastic lymphoma (LBL). METHODS We identified 173 patients with ALL and LBL, including 12 cases of mixed-phenotype acute leukemia, 8 cases of therapy-related B-cell ALL (B-ALL), 119 cases of B-ALL, and 34 cases of T-cell ALL/LBL diagnosed from 2003 to 2019. We retrospectively assessed p53 and MYC expression by immunohistochemistry of bone marrow and correlated MYC expression with p53 expression and TP53 aberration. RESULTS Expression of p53 and MYC was present in 11.5% and 27.7% of ALL/LBL cases (n = 20 and n = 48), respectively. MYC expression was significantly correlated with p53 expression and TP53 aberration (P = .002 and P = .03), and p53 expression and MYC expression had an adverse impact on OS in patients with ALL/LBL (P < .05). MYC and p53 dual expression as well as combined MYC expression and TP53 aberration had a negative impact on OS in patients with ALL/LBL. CONCLUSIONS MYC expression is correlated with p53 overexpression, TP53 aberration, and poor OS in patients with ALL/LBL.

Abstract
The co-occurrence of thymoma and T-lymphoblastic lymphoma/leukemia is an extremely rare but previously reported association that poses a diagnostic and therapeutic challenge. We describe a 67-year-old patient with long-standing untreated B1 thymoma that presented with constitutional symptoms and a painless soft tissue mass on the right chest wall. Pathological analysis of the biopsy from the mass demonstrated T-lymphoblastic leukemia/lymphoma. The patient went through a complicated course, was refractory to several lines of therapy, and eventually underwent allogeneic hematopoietic stem cell transplantation in complete remission from a matched related donor. The association between thymoma and malignant neoplasms has been described in the literature, most notably with colorectal adenocarcinoma and thyroid cancer. Thymoma-associated leukemia is, however, extremely unusual, with limited reports in the literature. Distinguishing between thymoma and leukemia can be challenging and often requires meticulous diagnostic efforts. For patients with a past history of thymoma, awareness of this particular association should be bared in mind to allow earlier diagnosis and therapy.

Abstract
T-acute lymphoblastic leukemia (T-ALL) generally have nodal presentation while B-cell leukemia and lymphoma may have extra-nodal or visceral involvement. Intra-abdominal presentation of T-ALL is exceedingly rare. Bilateral ovarian involvement at the time of initial presentation of T-ALL has never been described in children, though it may be seen during relapses. The authors describe a toddler with T-ALL who presented with bilateral ovarian mass. Despite complete resolution of ovarian mass post-induction chemotherapy, minimum residual disease in bone marrow was high reaffirming aggressive nature of disease.

Abstract
The role of cortactin in T-cell acute lymphoblastic leukemia (T-ALL) tissue infiltration has been previously reported. However, its impact on patients' responsiveness to therapy and patient's outcome was not previously addressed. This study was conducted on 60 T-ALL pediatric patients at diagnosis and 10 nonleukemic controls. Cortactin and HS1 expressions were identified by real-time polymerase chain reaction. Cortactin and HS1 expression were significantly higher in T-All patients as compared with controls as well as postinduction levels (P≤0.001 for both). The high cortactin expression was significantly associated with high peripheral white cell counts (P≤0.001), blood blast cells (P≤0.001) and central nervous system (CNS) infiltration (P≤0.001), and early precursor T-ALL subtype (P≤0.001) as compared with the remaining groups. The induction of remission response was significantly higher in T-ALL patients with lower cortactin expression levels as compared with T-ALL patients with higher one (P≤0.001). The high cortactin and HS1 expressions were significantly predictors of CNS infiltrations (hazard ratios [HR]: 1.051, confidence interval [CI]: 1.02-1.13, P=0.04 and HR: 1.87, CI: 1.23-2.091, P=0.002, respectively) and bone marrow relapse (HR: 1.43, CI: 1.18-1.92, P=0.004 and HR: 1.07, CI: 1.01-1.24, P=0.002, respectively). Furthermore, high cortactin expression levels were associated with shorter B-ALL patients' overall survival as compared with those with lower cortactin levels (P=0.002). In conclusion, high expression of cortactin and/or HS1 at diagnosis is a bad prognostic marker of T-ALL patients' outcome. Moreover, cortactin and/or HS1 expression could be used as a biomarker for refining risk stratification of T-ALL.

Abstract
Rasburicase is a recombinant urate oxidase enzyme indicated for tumor lysis syndrome, a potential life-threatening oncologic emergency that occurs most commonly during initial chemotherapy for hematological malignancies. As a result of the defects in the physiological antioxidant pathway, erythrocytes of patients with glucose-6-phosphate dehydrogenase deficiency are not protected against the oxidizing stress exerted by hydrogen peroxide generated with the administration of rasburicase. The authors report a 14-year-old patient, diagnosed with T-cell acute lymphoblastic leukemia, who developed methemoglobinemia and hemolytic anemia with low oxygen saturation after starting steroids, hyperhydratation, and rasburicase administration. The complications resolved with supportive therapy only.

Abstract
AIM Outcomes of children with high-risk (HR) relapsed acute lymphoblastic leukaemia (ALL) (N = 393), recruited to ALLR3 and ALL-REZ BFM 2002 trials, were analysed. Minimal residual disease (MRD) was assessed after induction and at predetermined time points until haematopoietic stem cell transplantation (SCT). METHODS Genetic analyses included karyotype, copy-number alterations and mutation analyses. Ten-year survivals were analysed using Kaplan-Meier and Cox models for multivariable analyses. RESULTS Outcomes of patients were comparable in ALLR3 and ALL-REZ BFM 2002. The event-free survival of B-cell precursor (BCP) and T-cell ALL (T-ALL) was 22.6% and 26.2% (P = 0.94), respectively, and the overall survival (OS) was 32.6% and 28.2% (P = 0.11), respectively. Induction failures (38%) were associated with deletions of NR3C1 (P = 0.002) and BTG1 (P = 0.03) in BCP-ALL. The disease-free survival (DFS) and OS in patients with good vs poor MRD responses were 57.4% vs 22.6% (P < 0.0001) and 57.8% vs 32.0% (P = 0.0004), respectively. For BCP- and T-ALL, the post-SCT DFS and OS were 42.1% and 56.8% (P = 0.26) and 51.6% and 55.4% (P = 0.67), respectively. The cumulative incidences of post-SCT relapse for BCP- and T-ALL were 36.9% and 17.8% (P = 0.012) and of death were 10.7% and 25.5% (P = 0.013), respectively. Determinants of outcomes after SCT were acute graft versus host disease, pre-SCT MRD (≥10-3), HR cytogenetics and TP53 alterations in BCP-ALL. CONCLUSION Improvements in outcomes for HR ALL relapses require novel compounds in induction therapy to improve remission rates and immune targeted therapy after induction to maintain remission after SCT.

Abstract
T-cell acute lymphoblastic leukemia (T-ALL) is a rare entity in the adult acute leukemia setting. Translocation (9;22)(q34;q11) and BCR-ABL1 rearrangement are occasionally found in T-ALL and have been reported in no more than 100 cases in the literature (most of which are chronic myeloid leukemia blast crisis). Here, we report the remarkable effectiveness of third-generation tyrosine-kinase inhibitor ponatinib in obtaining hematological and metabolic remission, in a patient with Philadelphia chromosome-positive de novo T-ALL and outcomes of a therapeutic strategy containing chemotherapy intensification, nelarabine, and allogeneic hematopoietic stem cell transplantation.

Abstract
T cell acute lymphoblastic leukemia (T-ALL) is a biologically and genetically heterogeneous disease with a poor prognosis overall and several subtypes. The neoplastic transformation takes place through the accumulation of numerous genetic and epigenetic abnormalities. There are only a few prognostic factors in comparison to B cell precursor acute lymphoblastic leukemia, which is characterized by a lower variability and more homogeneous course. The microarray and next-generation sequencing (NGS) technologies exploring the coding and non-coding part of the genome allow us to reveal the complexity of the genomic and transcriptomic background of T-ALL. miRNAs are a class of non-coding RNAs that are involved in the regulation of cellular functions: cell proliferations, apoptosis, migrations, and many other processes. No miRNA has become a significant prognostic and diagnostic factor in T-ALL to date; therefore, this topic of investigation is extremely important, and T-ALL is the subject of intensive research among scientists. The altered expression of many genes in T-ALL might also be caused by wide miRNA dysregulation. The following review focuses on summarizing and characterizing the microRNAs of pediatric patients with T-ALL diagnosis and their potential future use as predictive factors.

Abstract
Acute lymphoblastic leukaemia (ALL) is a relevant form of childhood neoplasm, as it accounts for over 80% of all leukaemia cases. T-cell ALL constitutes a genetically heterogeneous cancer derived from T-lymphoid progenitors. The diagnosis of T-ALL is based on morphologic, immunophenotypic, cytogenetic, and molecular features, thus the results are used for patient stratification. Due to the expression of surface and intracellular antigens, several subtypes of T-ALL can be distinguished. Although the aetiology of T-ALL remains unclear, a wide spectrum of rearrangements and mutations affecting crucial signalling pathways has been described so far. Due to intensive chemotherapy regimens and supportive care, overall cure rates of more than 80% in paediatric T-ALL patients have been accomplished. However, improved knowledge of the mechanisms of relapse, drug resistance, and determination of risk factors are crucial for patients in the high-risk group. Even though some residual disease studies have allowed the optimization of therapy, the identification of novel diagnostic and prognostic markers is required to individualize therapy. The following review summarizes our current knowledge about genetic abnormalities in paediatric patients with T-ALL. As molecular biology techniques provide insights into the biology of cancer, our study focuses on new potential therapeutic targets and predictive factors which may improve the outcome of young patients with T-ALL.

Abstract
BACKGROUND Adult T cell acute lymphoblastic leukemia (T-ALL) is a rare disease that affects less than 10 individuals in one million. It has been less studied than its cognate pediatric malignancy, which is more prevalent. A higher percentage of the adult patients relapse, compared to children. It is thus essential to study the mechanisms of relapse of adult T-ALL cases. RESULTS We profile whole-genome somatic mutations of 19 primary T-ALLs from adult patients and the corresponding relapse malignancies and analyze their evolution upon treatment in comparison with 238 pediatric and young adult ALL cases. We compare the mutational processes and driver mutations active in primary and relapse adult T-ALLs with those of pediatric patients. A precise estimation of clock-like mutations in leukemic cells shows that the emergence of the relapse clone occurs several months before the diagnosis of the primary T-ALL. Specifically, through the doubling time of the leukemic population, we find that in at least 14 out of the 19 patients, the population of relapse leukemia present at the moment of diagnosis comprises more than one but fewer than 108 blasts. Using simulations, we show that in all patients the relapse appears to be driven by genetic mutations. CONCLUSIONS The early appearance of a population of leukemic cells with genetic mechanisms of resistance across adult T-ALL cases constitutes a challenge for treatment. Improving early detection of the malignancy is thus key to prevent its relapse.

Abstract
PURPOSE The Children's Oncology Group (COG) protocol AALL0434 evaluated the safety and efficacy of multi-agent chemotherapy with Capizzi-based methotrexate/pegaspargase (C-MTX) in patients with newly diagnosed pediatric T-cell lymphoblastic lymphoma (T-LL) and gained preliminary data using nelarabine in high-risk patients. PATIENTS AND METHODS The trial enrolled 299 patients, age 1-31 years. High-risk (HR) patients had ≥ 1% minimal detectable disease (MDD) in the bone marrow at diagnosis or received prior steroid treatment. Induction failure was defined as failure to achieve a partial response (PR) by the end of the 4-week induction. All patients received the augmented Berlin-Frankfurt-Muenster (ABFM) C-MTX regimen. HR patients were randomly assigned to receive or not receive 6 5-day courses of nelarabine incorporated into ABFM. Patients with induction failure were nonrandomly assigned to ABFM C-MTX plus nelarabine. No patients received prophylactic cranial radiation; however, patients with CNS3 disease (CSF WBC ≥ 5/μL with blasts or cranial nerve palsies, brain/eye involvement, or hypothalamic syndrome) were ineligible. RESULTS At end-induction, 98.8% of evaluable participants had at least a PR. The 4-year event-free survival (EFS) and overall survival (OS) were 84.7% ± 2.3% and 89.0% ± 2.0%. The 4-year disease-free survival (DFS) from end-induction was 85.9% ± 2.6%. There was no difference in DFS observed between the HR and standard-risk groups (P = .29) or by treatment regimen (P = .55). Disease stage, tumor response, and MDD at diagnosis did not demonstrate thresholds that resulted in differences in EFS. Nelarabine did not show an advantage for HR patients. CNS relapse occurred in only 4 patients. CONCLUSION COG AALL0434 produced excellent outcomes in one of the largest trials ever conducted for patients with newly diagnosed T-LL. The COG ABFM regimen with C-MTX provided excellent EFS and OS without cranial radiation.

Abstract
Early T-cell precursor (ETP) is the only subtype of acute T-cell lymphoblastic leukemia (T-ALL) listed in the World Health Organization (WHO) classification of myeloid neoplasms and acute leukemia. Patients with ETP tend to have worse disease outcomes. ETP is defined by a series of immune markers. The diagnosis of ETP status can be vague due to the limitation of the current measurement. In this study, we performed unsupervised clustering and supervised prediction to investigate whether a molecular biomarker can be used to identify the ETP status in order to stratify risk groups. We found that the ETP status can be predicted by the expression level of Lymphoid enhancer binding factor 1 (LEF1) with high accuracy (AUC of ROC = 0.957 and 0.933 in two T-ALL cohorts). The patients with ETP subtype have a lower level of LEF1 comparing to the those without ETP. We suggest that incorporating the biomarker LEF1 with traditional immune-phenotyping will improve the diagnosis of ETP.

Abstract
RATIONALE The diagnosis of hematological malignancies depends on laboratory analysis and often requires multiple experimental methods to judge, otherwise misdiagnosis is apt to happen. Lymph node biopsy immunohistochemistry (IHC) for T-lymphoblastic lymphoma (T-LBL) requires the establishment of antibody set screening. For identifying T-LBL and early T-cell precursor acute lymphoblastic leukemia (ETP-ALL) by lymph node biopsy and IHC, WHO has not yet proposed a better IHC antibody combination. PATIENT CONCERNS Here we reported 1 case with tortuous diagnosis experience. Initially, a 51-year-old man was diagnosed as T-LBL by lymph node biopsy, but in another hospital acute myeloid leukemia (AML) was confirmed by bone marrow puncture. Finally, it was diagnosed as mixed phenotype acute leukemia (MPAL) through our comprehensive evaluation including bone marrow cell morphology, cytochemical staining and flow cytometry analysis. Importantly, the experience about differential diagnosis and our appreciation among the T-LBL, ETP-ALL and MPAL was discussed to enlighten readers. DIAGNOSES The patient was diagnosed with mixed phenotype acute leukemia (T+My)-NOS. INTERVENTIONS The patient received 1 cycle of VDCLP scheme treatment firstly. The effect of chemotherapy is satisfactory, and then he received continuous treatment and was currently in good condition. OUTCOMES This patient is alive at present. The follow-up period has been 1 year. LESSONS For the diagnosis of T-LBL, the molecular markers of the myeloid and lymphoid tissues need to be included, such as CD117, CD33, Lys and MPO. The bone marrow puncture also needs to be conducted to distinguish T-LBL and T-ALL. Secondly, to identify ETP-ALL and MPAL, bone marrow cell morphology, cytochemical staining as well as flow cytometric analysis were needed to make a clear diagnosis. It is recommended that at least CD8, CD1a, Lys and MPO should be included in the panel to identify ETP-ALL.

Abstract
PURPOSE We aimed to investigate the prognostic value of DNA index (DI) in children with precursor B cell acute lymphoblastic lymphoma (pre-B ALL). MATERIALS AND METHODS From January 2003 to December 2014, 72 children diagnosed with pre-B ALL were analyzed. We analyzed the prognostic value of DI and its relations with other prognostic factors. RESULTS The DI cut-point of 1.16 did not discriminate significantly the groups between high and low survivals (DI≥1.16 versus <1.16; 5-year OS, 90.5% vs. 82.8%, p=0.665). We explored the survivals according to the level of DI (<1.00, 1.00, 1.01-1.30, 1.31-1.60, 1.61-1.90, and >1.90), and the survival of children with a DI between 1.00-1.90 were significantly higher than that of children with DI of <1.00 or >1.90 (5-year OS, 90.6% vs. 50.0%, p<0.001). CONCLUSIONS The DI of 1.16 was not a significant cut-point discriminating the risk group in children with pre-B ALL. However, the DI divided by specific ranges of values remained an independent prognostic factor. Further studies are warranted to re-evaluate the prognostic value and cut-point of DI in children treated with recent treatment protocols.

Abstract
BACKGROUND Lymphoblastic lymphoma (LBL) is a rare form of non-Hodgkin's lymphoma (NHL). Cutaneous LBL is seen in less than 20% of patients. PATIENTS AND METHODS Herein, we report the case of a 66-year-old male patient without any previous disease history of note and who was presenting a gradually spreading tumoral lesion of the scalp, several purplish macules and nodules on the trunk, and a single spinal adenopathy. A thoracic-abdominal-pelvic CT scan performed for acute renal failure, revealed extensive infiltration of retroperitoneal tissue. Skin biopsies and staging tests indicated LBL-T with associated cutaneous, bone and lymph node retroperitoneal lesions with no mediastinal mass. After two months of treatment with CHOP (four courses), the cutaneous lesions and abdominal tumoral mass had regressed and renal function had returned to normal. DISCUSSION There have been 13 reported cases of LBL with cutaneous involvement; most of these patients were young (under 30 years) and presented multiple cutaneous lesions (nodules or tumors) associated with numerous peripheral adenopathies, invasion of the bone marrow, and in many cases, a mediastinal mass. The clinical presentation of LBL-T in our case is novel on account of the cutaneous sites, associated with abdominal tumoral syndrome, without mediastinal infiltration, and with a single peripheral adenopathy, in an elderly subject.

Abstract
T-cell acute lymphoblastic leukemia (T-ALL) comprises 15% of childhood leukemia. Although multiagent pulse chemotherapy has improved event-free survival in recent decades, the lack of reliable prognosticators and high rate of relapse remain a challenge. Described is a novel discovery of tumor-derived hyperprolactinemia in childhood T-ALL through a case associated with paraneoplastic galactorrhea. Prolactin production by tumor cells, although a rare phenomenon, is previously demonstrated in several adult cancers and 2 pediatric malignancies with unknown implications. This is the first report demonstrating tumor-derived prolactin in pediatric T-ALL and offers potential as a disease marker and therapeutic drug target.

Abstract
T-cell acute lymphoblastic leukemia (T-ALL) is biologically distinct from its B lymphoblastic (B-ALL) counterpart and shows different kinetic patterns of disease response. Although very similar regimens are used to treat T-ALL and B-ALL, distinctions in response to different elements of therapy have been observed. Similar to B-ALL, the key prognostic determinant in T-ALL is minimal residual disease (MRD) response. Unlike B-ALL, other factors including age, white blood cell count at diagnosis, and genetics of the ALL blasts are not independently prognostic when MRD response is included. Recent insights into T-ALL biology, using modern genomic techniques, have identified a number of recurrent lesions that can be grouped into several targetable pathways, including Notch, Jak/Stat, PI3K/Akt/mTOR, and MAPK. With contemporary chemotherapy, outcomes for de novo T-ALL have steadily improved and now approach those observed in B-ALL, with approximately 85% 5-year event-free survival. Unfortunately, salvage has remained poor, with less than 25% event-free and overall survival rates for relapsed disease. Thus, current efforts are focused on preventing relapse by augmenting therapy for high-risk patients, sparing toxicity in favorable subsets and developing new approaches for the treatment of recurrent disease.

Abstract
Gene expression, copy number variations (CNV), mutations and survival were studied to delineate TCRγδ+T-cell acute lymphoblastic leukemia (T-ALL) as a distinct subgroup from TCRαβ+T-ALL. Gene Ontology analysis showed that differential regulation of genes involved in pathways for leukemogenesis, apoptosis, cytokine-cytokine receptor interaction and antigen processing/presentation may offer a survival benefit to TCRγδ+T-ALL patients. Genes involved in disease biology and having equal expression in both the subgroups, were further analysed for mutations and CNV using droplet digital PCR. TCRγδ+T-ALL patients exhibited differential level of mutations for NOTCH1 and IKZF3; however BRAF mutations were detected at equal levels in both the subgroups. Although TCRγδ+T-ALL patients with these mutations demonstrated improved disease-free survival (DFS) as compared TCRαβ+T-ALL patients, it was not statistically significant. Patients with homozygous deletion of CDKN2A/CDKN2B showed poor DFS in each subgroup. TCRγδ+T-ALL patients with wild type/heterozygous deletion of CDKN2A/CDKN2B possess significantly better DFS over TCRαβ+T-ALL patients (p=0.017 and 0.045, respectively). Thus, the present study has for the first time demonstrated TCRγδ clonality and CDKN2A/CDKN2B CNV together as potential prognostic markers in management of T-ALL. Further understanding the functional significance of differentially regulated genes in T-ALL patients would aid in designing risk based treatment strategies in subset specific manner.

Abstract
OBJECTIVES The diagnosis of T-lymphoblastic leukemia/lymphoma (T-ALL) involving the thymus can be difficult to establish since neoplastic T lymphoblasts show significant phenotypic overlap with both normal thymocytes and thymocytes from epithelial thymic neoplasms (thymomas). LIM Domain Only 2 (LMO2) gene translocations have been implicated in the pathogenesis of a small subset of T-ALLs, and LMO2 protein has recently been reported to be expressed in a large proportion of T-ALLs. METHODS In this study, we tested specificity of LMO2 for distinction between neoplastic and nonneoplastic T-precursor cells in thymus and bone marrow. RESULTS Our findings show that LMO2 is expressed in neoplastic lymphoblasts of T-ALL and is absent in thymocytes of normal thymuses or thymomas. CONCLUSIONS LMO2 is therefore a useful marker for immunophenotypic assessment of thymic neoplasms.

Abstract
OBJECTIVE To study the C-myc gene and protein in T lymphoblastic lymphoma/leukemia (T-LBL/ALL) and its relationship to prognosis. METHODS 60 cases of T-LBL/ALL with follow-up data were studied by using immunohistochemical EnVision method for CD1a, CD3, εCD3, CD7, CD10, CD34, CD43, CD45RO, CD99, TDT, CD20, CD23, MPO, Ki-67 and C-myc. 20 cases of reactive lymph nodes were selected as normal control group of C-myc gene and protein. Fluorescence in-situ hybridization (FISH) for C-myc gene (located on chromosome8q24) was performed to detect its breakage and gain. RESULTS Among the 60 cases of T-LBL/ALL, immunohistochemistry results showed:the percentages of tumor cells expression of CD1a, CD3, εCD3, CD7, CD10, CD34, CD43, CD45RO, CD99 and TDT were 38.3% (23/60), 75.0% (45/60), 45.0% (27/60), 95.0% (57/60), 36.7% (22/60), 23.3% (14/60), 60.0% (36/60), 41.7% (25/60), 96.7% (58/60) and 93.3% (56/60). Separately, while CD20, CD23 and MPO were all negative. A figure of Ki-67 expression ≤ 80% was found in 36 cases and > 80% was found in 24 cases. The positive rate of C-myc protein was 66.7% (40/60) in 60 cases of T-LBL/ALL, was 0% (0/20) in 20 cases of reactivated lymphoid tissue (χ² = 26.67, P < 0.05). C-myc protein expression was positively correlated with the mediatinal width and Ki-67 index (P < 0.05). Fluorescence in-situ hybridization results showed that among the 60 cases of T-LBL/ALL, C-myc gene with breakage of 8q24 was detected in 6 cases (10.0%), and gains in 11 cases (18.3%). 20 cases of reactive lymph nodes were not occurred breakage and gains of C-myc gene. It is not significant between C-myc gene and protein expression (P > 0.05). In addition, in 60 cases of T-LBL/ALL, 12(20.0%) cases of C-myc protein and genetic abnormalities coexist. Log-rank analysis results: The prognosis of C-myc protein positive group was worse than negative group (P < 0.05). The relationship of C-myc gene and prognosis was not significant (P > 0.05). C-myc protein and genetic abnormality coexist is related with worse prognosis (P < 0.05). COX analysis results show that the C-myc protein positive group may be a independent poor prognosis factors (P < 0.05). CONCLUSIONS C-myc may play an important role on the development of T-LBL/ALL. It may be a independent prognosis factors.

Abstract
INTRODUCTION Acute lymphoblastic leukaemia (ALL) in children may have atypical presentations causing diagnostic delay. Guidelines for prompt referral have been published. The utility of the specified criteria is unknown. MATERIAL AND METHODS Symptoms, signs and laboratory findings at the time of diagnosis were reviewed in a consecutive series of 100 children with ALL in order to determine the frequency of atypical features and to evaluate the Danish referral guideline. RESULTS Only 36% had involvement of all three haematopoietic cell lines, and 23% presented with the classic clinical triad of pallor, fever and purpura. Symptoms of bone marrow insufficiency had been present in 77% for an average of two weeks as a late occurrence following musculoskeletal pains (in 49%, duration eight weeks) and constitutional symptoms (in 82%, duration four weeks). Organ infiltration was manifest in 71%. In 22%, only one or no cell count was abnormal; in this group, musculoskeletal symptoms were more frequent and symptom duration longer (two months versus one month). In 15%, lymphoblasts could not be detected in the blood. At the time of diagnosis, the Danish criteria for accelerated investigation were fulfilled in 98% of cases. CONCLUSION The clinical presentation of ALL is variable, and full-blown bone marrow insufficiency is a late occurrence as the disease progresses. Reduction of the diagnostic interval requires meticulous examination for organomegaly and attention to subtle haematologic changes. FUNDING Not relevant. TRIAL REGISTRATION Not relevant.

Abstract
T-cell posttransplant lymphoproliferative disorders after solid-organ transplant are rare and may be clinically aggressive. A 3-year-old boy had liver transplant from his grandfather because of hepatoblastoma. The immunosuppressive regimen was based on tacrolimus and prednisolone. At 22 months after transplant (age, 5 years), the patient presented to the hospital because of severe cough. Computed tomography scan of the chest showed a large left mediastinal mass (9 × 7.2 × 7 cm) and left pleural effusion. A Tru-Cut biopsy of the mediastinal mass showed diffuse infiltration with blast cells, and the diagnosis of T-cell acute lymphoblastic leukemia was made. Immunohistochemical examination of blasts showed strong and diffuse terminal deoxynucleotidyl transferase and CD3 antibody expression; Ki-67 proliferation index was > 95%, and tumor cells were negative for Epstein-Barr virus. Tacrolimus was stopped, sirolimus was started, and chemotherapy was given, but he died 2 months after diagnosis because of chemotherapy-induced sepsis. Monomorphic T-cell posttransplant lymphoproliferative disorder with features of acute lymphoblastic leukemia and lymphoblastic lymphoma is rare after liver transplant.

Abstract
A 22-year-old woman presented with high fever, chest tightness and cough in January 20XX. Since CT scans revealed an anterior mediastinal mass, percutaneous needle biopsies of the mass were performed and she was diagnosed with T-cell lymphoblastic lymphoma (T-LBL). After the immunophenotype of lymphocytes in her pleural effusion had been identified, she received CHOP therapy because her dyspnea worsened, and induction therapy for acute lymphoblastic leukemia was subsequently performed after confirmation of her diagnosis as T-LBL. During this induction therapy, she developed paralytic ileus. One week thereafter, she suddenly exhibited visual disturbance, headache and nausea. Her cerebrospinal fluid was normal. Magnetic resonance imaging showed symmetrical high signal intensities on T2-weighted and fluid-attenuated inversion recovery images, and low signal intensities on T1-weighted images in the cortical and subcortical white matter of the posterior parietal and occipital lobes. Based on these findings, she was diagnosed as having posterior reversible encephalopathy syndrome (PRES). During chemotherapy for hematologic malignancies, some patients with PRES reportedly develop paralytic ileus or tumor lysis syndrome. PRES should be considered in patients with neurological abnormalities following such complications during chemotherapy.

Abstract
BACKGROUND Immune regulation is important for the pathogenesis of T-cell acute lymphoblastic leukemia (T-ALL). Th22 cells are recently-identified CD4(+) T cells that implicated in the pathogenesis of many hematological diseases, such as AML. However, the role of Th22 cells in the pathophysiology of T-ALL remains unclear. We examined the Th22, Th17 and Th1 cell frequencies in peripheral blood of T-ALL patients. METHODS We studied 24 newly-diagnosed (ND), 17 morphologic complete remission (CR) T-ALL patients and 30 healthy controls. Th subsets were examined by flow cytometry. Plasma IL-22 and IL-17 concentrations were measured by ELISA. Transcription factor RORC, T-bet and AHR mRNA expressions were examined by RT-PCR. RESULTS Th22, Th17 frequencies, plasma IL-22 concentration and AHR expression were significantly increased in ND or CR T-ALL patients compared with controls. Moreover, Th22 showed positive correlation with Th17 or Th1 cells in T-ALL patients. However, a significant decrease of IL-17 concentration, Th1 frequency and T-bet expression was found in ND or CR ALL patients compared with controls. Furthermore, Th17 cells showed positive correlation but Th1 cells showed negative correlation with white blood cell counts. CONCLUSION The profile of Th subsets was distinct for T-ALL patients and showed some correlations with clinical index, which suggest that these Th subsets may be implicated in the pathogenesis of T-ALL and be reasonable targets for therapeutic intervention.

Abstract
Background Treatment of pediatric T-cell acute lymphoblastic leukemia (T-ALL) has improved, but there is a considerable fraction of patients experiencing a poor outcome. There is a need for better prognostic markers and aberrant DNA methylation is a candidate in other malignancies, but its potential prognostic significance in T-ALL is hitherto undecided. Design and Methods Genome wide promoter DNA methylation analysis was performed in pediatric T-ALL samples (n = 43) using arrays covering >27000 CpG sites. Clinical outcome was evaluated in relation to methylation status and compared with a contemporary T-ALL group not tested for methylation (n = 32). Results Based on CpG island methylator phenotype (CIMP), T-ALL samples were subgrouped as CIMP+ (high methylation) and CIMP− (low methylation). CIMP− T-ALL patients had significantly worse overall and event free survival (p = 0.02 and p = 0.001, respectively) compared to CIMP+ cases. CIMP status was an independent factor for survival in multivariate analysis including age, gender and white blood cell count. Analysis of differently methylated genes in the CIMP subgroups showed an overrepresentation of transcription factors, ligands and polycomb target genes. Conclusions We identified global promoter methylation profiling as being of relevance for subgrouping and prognostication of pediatric T-ALL.

Abstract
T-cell acute lymphoblastic leukemia is a hematologic malignancy with propensity to involve extramedullary organs including the eyes. Optic nerve infiltration is relatively rare. This is the case study of a 25-year-old- man who was in full remission following treatment for T-cell acute lymphoblastic leukemia and presented with bilateral leukemic optic nerve infiltration as the first manifestation of extramedullary relapse. The patient was treated with urgent radiotherapy and systemic dexamethasone. Over the following period, gradual resolution of optic disc swelling was noted in both eyes with marked improvement in vision in the right eye. Unfortunately, a few weeks later, a full blown hematological relapse was diagnosed. Salvage chemotherapy was instituted but was complicated by tumor lysis syndrome and septicemia that proved to be fatal. Ophthalmic assessment is essential in patients with hematological malignancies in order to diagnose ocular involvement as a result of malignant infiltration, hematological disturbances or as a complication of systemic therapy.

Abstract
T-cell lymphomas represent a heterogeneous group of neoplasms that encompass considerable clinical, morphologic, and immunophenotypic variation. The diagnosis of T-cell lymphoma is challenging because of its relative rarity, the lack of an immunophenotypic marker of clonality, and significant morphologic overlap with infectious/inflammatory processes and neoplasms, including Hodgkin and other non-Hodgkin lymphomas, and even mesenchymal or epithelial lesions. In the current World Health Organization classification of hematopoietic tumors, all except 1 subtype (ie, T-lymphoblastic lymphoma) are recognized as mature neoplasms derived from postthymic T cells. In addition to T-lymphoblastic lymphoma, this review will focus on nodal and extranodal T-cell lymphomas and exclude T-cell lymphomas presenting primarily in the skin. Extranodal natural-killer-cell/T-cell lymphoma, nasal type, will also be discussed because the derivation of this lymphoma from natural killer and natural killer-like T cells shows morphologic and immunophenotypic features that overlap with other T-cell lymphomas. In this review, we discuss the salient clinicopathologic, immunophenotypic, and genetic features, as well as our approaches to the diagnosis of lymphoblastic, nodal, and extranodal T-cell lymphomas.

Abstract
This study was aimed to explore the clinical features and prognosis outcome of childhood T-cell acute lymphoblastic leukemia (T-ALL). The clinical data of 38 cases of newly diagnosed T-ALL from Jan 2005 to Aug 2010 were analyzed retrospectively, and 78 cases of B-ALL with intermediate and high risk were collected as control group, then the sensitive rate of patients to prednisone pretreatment, complete remission (CR) rate at day 33 after induction chemotherapy, relapse rate and 3-year event-free survival (EFS) were compared between T-ALL and B-ALL children. The results showed that no significant statistic difference were found in distribution of age, infiltration of liver, spleen and lymph nodes as well as central nervous system disease, chromosome abnormality, expression level of fusion gene and so on between T-ALL and B-ALL groups (p > 0.05), but there were significant differences in sex and number of cases with WBC count ≥ 50 × 10(9)/L between them (p < 0.05). The sensitive rate of T-ALL and B-ALL patients to prednisone pretreatment was 51.9% and 89.3% respectively (p < 0.05). The ratio failed to achieve CR at day 33 after induction chemotherapy was 15.4% and 8.1% in the two groups (p > 0.05). The relapse rate of T-ALL and B-ALL cases was 30.8% (8/26) and 14.9% (11/74) respectively (p > 0.05). The time from CR to relapse was (9.78 ± 3.48) month and (21.28 ± 14.32) month (p < 0.05). The 3 year EFS of T-ALL cases with intermediate and high risk was (37.5 ± 17.1)% and (22.2 ± 9.8)%, while 3 year EFS of B-ALL cases was (66.7 ± 7)% and (51.7 ± 9.3)% respectively (p < 0.05) according to Kaplan-Meier survival curve. It is concluded that as compared with B-ALL cases, the male ratio and initial WBC count are higher, moreover the early response to prednisone pretreatment and 3 year EFS are poor in T-ALL cases, the prognosis outcome is poor also.
