Clinically, T-ALL presents with hyperleukocytosis, mediastinal disease, and/or involvement of the central nervous system. T-ALL is a high-risk subgroup within pediatric cohorts whereas among adults, outcomes are similar or better than that of B-cell acute lymphoblastic leukemia (B-ALL). Most T-ALL patients have mutations in <i>NOTCH</i> or <i>FBXW7</i> (a <i>NOTCH</i> regulator) which suggests a common pathway of disease pathogenesis. The presence of one of these mutations confers a favorable prognosis in the absence of mutations in <i>RAS</i> and <i>PTEN</i>. Early T-precursor (ETP)-ALL is a high-risk subgroup of T-ALL that is characterized by stem-cell-like features, absence of <i>NOTCH</i> pathway mutations, and resistance to chemotherapy. Patients with T-ALL should be treated with intensive, ideally asparaginase-based, chemotherapy regimens. Allogeneic transplant is considered for consolidation of some adults with high-risk disease, including those with ETP-ALL or poor response to therapy. Relapsed T-ALL can be treated with nelarabine, but outcomes are poor and new therapies are needed.</p>","PeriodicalId":72084,"journal":{"name":"Advances in cell and gene therapy","volume":"2 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/acg2.70","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45470680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite using intensive multiagent chemotherapy followed by a prolonged maintenance or allogeneic stem cell transplantation, these patients remain at a high risk of relapse. Improved techniques for detection of measurable residual disease (MRD) have tremendously changed the posttreatment disease burden assessment and evolved as a powerful predictor of relapse and survival superseding historical prognostic factors. Moreover, MRD measurement has become an integral part of risk stratification, prognosis assessment, intensification or de-escalation of treatment, monitoring of disease burden, and an endpoint in clinical trials. With existing approaches like allogeneic hematopoietic stem cell transplantation and emergence of novel agents (eg, blinatumomab, inotuzumab ozogamicin, and chimeric antigen receptor [CAR] T cells) that are highly effective in eradicating residual disease, understanding the role of MRD in treatment decisions is getting more and more important and complex.

We, therefore, established a standardized approach for the assessment of chronic GVHD in accordance with the NIH consensus criteria (NCC) guidelines. At a single institution, all allograft recipients were evaluated for GVHD within the first-year post allo-HCT following a three-step workflow (real-time assessment, consensus review, and documentation). A GVHD adjudication committee was created and a dynamic electronic GVHD data capture form was developed guiding the clinician through a comprehensive review of systems following the NCC guidelines. We found that the assessment and reporting of GVHD reached 100% compliance. The establishment of an institutional GVHD adjudication committee enabled standardized assessment of GVHD.

Although, as a group, these inhibitors have led to one of the most successful targeted therapies in leukemia, Ph+ ALL still remains a formidable disease. Unlike chronic myeloid leukemia (CML) where TKIs lead to dramatic long-lasting responses as single agents, the biology of Ph+ ALL is far more complex and adjunctive therapies are mandatory. These may include corticosteroids, chemotherapy, antibody-based therapies or, even, allogeneic hematopoietic cell transplantation. Clearly, other genes or mutations are in place that affect the outcome of Ph+ ALL. Additional chromosomal abnormalities are common in Ph+ ALL and have a varying impact on prognosis; some adverse, others less so. Genomic alterations have come into their own in the last decade and have increased our understanding of the mechanisms of resistance and differing responses to therapy. In this review, these genetic aberrations will be considered in some detail. In addition, innovations in current practice – including the use of immunological therapies – will be carefully reviewed. For the first time in decades, the long-held imperative requiring an allogeneic transplant for a curative approach in adult Ph+ ALL is now being questioned and clinical trials are underway to resolve this issue. However, despite much progress in the past two decades, both in the biology and therapy of Ph+ ALL, this disease still presents a compelling challenge and much remains to be overcome.</p>","PeriodicalId":72084,"journal":{"name":"Advances in cell and gene therapy","volume":"2 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/acg2.60","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46696571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
