Survival of Myeloid Malignancies in EUROPE: Results of the HAEMACARE Project.
2009
Abstract Abstract 3911 Poster Board III-847 Background Updated ICD-O and WHO classifications of Haematological Malignancies (HMs) take into account cell lineage, genotype, morphological aspects, immuno-histochemical and genetic characteristics, and clinical behaviour of the disease, dividing Lymphoid and Myeloid neoplasms in subcategories with possible similar aetiology or prognosis. Thus, good quality of morphological data on HMs is capital. The HAEMACARE project aimed to increase standardization and the availability of Cancer Registries (CRs) morphological data on HMs, in order to improve comparability of incidence, survival and prevalence across Europe. This study aims to present the HAE…
Single umbilical cord blood with or without CD34+ cells from a third-party donor in adults with leukemia
2017
We retrospectively compared the clinical outcomes of adults with acute leukemia who received single-unit umbilical cord blood (UCB) transplantation (sUCBT) (n = 135) or stem cell transplant using coinfusion of a UCB graft with CD34+ cells from a third-party donor (Haplo-Cord) (n = 72) at different institutions within the Grupo Espanol de Trasplante Hematopoyetico. In multivariable analysis, patients in the Haplo-Cord group showed more rapid neutrophil (hazard ratio [HR], 2.3; 95% confidence interval [CI], 1.5-3.3; P < .001) and platelet recovery (HR, 1.6; 95% CI, 1.2-2.3; P = .015) and lower incidence of chronic graft-versus-host disease (GVHD) (relative risk, 0.5; 95% CI, 0.3-0.8; P = .01)…
Ittero ostruttivo come sintomo d'esordio in soggetto con leucemia monocitica acuta
2005
A 24-year-old man presented with abdominal pain, fever and jaundice. Ultrasound examination of the abdomen showed a lithiasis of the gallbladder and a dilatation of the common bile duct without stones inside. A MR cholangiography showed a stenosis in the distal tract of the common bile duct which was dilated. The same picture was demonstrated by an endoscopic retrograde cholangiopancreatography (ERCP). The patient underwent an explorative laparotomy. No stones were found in the gallbladder, but in its infundibular region a hard nodule was present and located in the thickness of the wall. Another hard lesion was palpable in the middle tract of the common bile duct. Some enlarged mesenteric a…
Burkholderia cepacia septicemia in a patient with acute myeloid leukemia in postchemotherapy bone marrow aplasia
2013
The patients with hematologic malignancies are predisposed to develop infections with unusual bacteria, like Burkholderia cepacia, which is frequently resistant to many antibiotics and antiseptics. We present the case of a female patient with acute myeloid leukemia type 2 on the background of myelodysplastic syndrome, from whom Burkholderia cepacia was isolated in blood culture, after the 2(nd) cycle of induction. She was sensitive to ceftazidime, but its eradication was not easy. Five other patients were contaminated with this bacteria, but all of them had favourable evolution. The case is discussed in the context of those similar in literature.
Therapy-Related Myeloid Neoplasms in Patients With Acute Promyelocytic Leukemia Treated With All-Trans-Retinoic Acid and Anthracycline-Based Chemothe…
2010
Purpose We analyzed the incidence, risk factors, and outcome of therapy-related myeloid neoplasms (t-MNs) in patients with acute promyelocytic leukemia (APL) in first complete remission (CR). Patients and Methods From 1996 to 2008, 1,025 patients with APL were enrolled onto three sequential trials (LPA96, LPA99, and LPA2005) of the Programa Español para el Tratamiento de Enfermedades Hematológicas and received induction and consolidation therapy with all-trans-retinoic acid (ATRA) and anthracycline-based chemotherapy. Results Seventeen of 918 patients who achieved CR developed t-MN (10 with < 20% and seven with ≥ 20% of bone marrow blasts) after a median of 43 months from CR. Partial and…
Genotypic and Phenotypic Characteristics of Acute Promyelocytic Leukemia Translocation Variants.
2020
Acute promyelocytic leukemia (APL) is a special disease entity of acute myeloid leukemia (AML). The clinical use of all-trans retinoic acid (ATRA) has transformed APL into the most curable form of AML. The majority of APL cases are characterized by the fusion gene PML-RARA. Although the PML-RARA fusion gene can be detected in almost all APL cases, translocation variants of APL have been reported. To date, this is the most comprehensive review of these translocations, discussing 15 different variants. Reviewed genes involved in APL variants include: ZBTB16, NPM, NuMA, STAT5b, PRKAR1A, FIP1L1, BCOR, NABP1, TBLR1, GTF2I, IRF2BP2, FNDC3B, ADAMDTS17, STAT3, and TFG. The genotypic and phenotypic …
Myeloid sarcoma of the oral cavity : a case report and review of 89 cases from the literature
2017
Myeloid sarcoma is a tumor mass of immature myeloid or granulocytic cells that affects extramedullary anatomic sites, including uncommonly the oral cavity. A 24-year-old female was referred for evaluation of a fast growing painful gingival swelling lasting 2 weeks, associated with fever, fatigue, and cervical lymphadenopathy. Intraoral examination showed a bluish swelling on the right posterior lower gingiva exhibiting necrotic surface. Incisional biopsy of the gingival lesion displayed diffuse infiltration of undifferentiated tumor cells with granulocytic appearance, strongly immunopositive for CD99, myeloperoxidase and Ki-67 (60%), and negative for CD20, CD3, CD34 and TdT. Blood tests pre…
Predictors of Early Death in Childhood Acute Promyelocytic Leukemia: Results of an International Retrospective Study
2015
Abstract Background: Acute promyelocytic leukemia (APL) is a rare subtype of childhood acute myeloid leukemia (AML). Bleeding complications occur in 80% of patients at diagnosis and contribute to a higher incidence of early death (ED) in APL compared to other AML subtypes. However, estimates of ED in pediatric APL are imprecise and factors associated with ED in children with APL are unknown. Objectives: To determine the incidence and predictors of ED, defined as death within 60 days from presentation, in childhood APL. Methods: We conducted a retrospective international analysis of children diagnosed with APL between January 1993 and December 2013. The study included 236 patients from the I…
Towards More Specificity and Effectivity in the Antileukemia Immune Response
2014
Experimental and clinical studies have shown that alloreactive T-cell responses derived from donor lymphocytes can effectively eliminate leukemia cells after allogeneic hematopoietic stem cell transplantation. However, there are still too many patients in whom this graft-versus-leukemia reactivity is insufficient to prevent leukemia relapse or who suffer from severe alloreactivity to nonmalignant host tissues also mediated by donor-derived T cells. Therefore, various conceptually different approaches have been developed at the level of donor T cells in order to improve the efficacy of leukemia-directed immunity while reducing the incidence of unwanted graft-versus-host disease. As outlined …
Customised next-generation sequencing multigene panel to screen a large cohort of individuals with chromatin-related disorder
2020
BackgroundThe regulation of the chromatin state by epigenetic mechanisms plays a central role in gene expression, cell function, and maintenance of cell identity. Hereditary disorders of chromatin regulation are a group of conditions caused by abnormalities of the various components of the epigenetic machinery, namely writers, erasers, readers, and chromatin remodelers. Although neurological dysfunction is almost ubiquitous in these disorders, the constellation of additional features characterizing many of these genes and the emerging clinical overlap among them indicate the existence of a community of syndromes. The introduction of high-throughput next generation sequencing (NGS) methods f…
