PURPOSE: A cancer diagnosis and treatment may have significant implications for a young patient's future fertility. Documentation of fertility-related discussions and actions is crucial to providing the best follow-up care, which may occur for many years post-treatment. This study examined the rate of medical record documentation of fertility-related discussions and fertility preservation (FP) procedures for adolescents and young adults (AYAs) with cancer in Australia. METHODS: A retrospective review of medical records for 941 patients in all six Australian states...

Distinguishing classical dendritic cells from other myeloid cell types is complicated by the shared expression of cell surface markers. ZBTB46 is a zinc finger and BTB domain-containing transcription factor, which is expressed by dendritic cells and committed dendritic cell precursors, but not by plasmacytoid dendritic cells, monocytes, macrophages, or other immune cell populations. In this study, we demonstrate that expression of ZBTB46 identifies human dendritic cell neoplasms. We examined ZBTB46 expression in a range of benign and malignant histiocytic disorders and found that ZBTB46 is able to clearly define the dendritic cell identity of many previously unclassified histiocytic disease subtypes...

Isocitrate dehydrogenase (IDH) is one of the key enzymes in the tricarboxylic acid cycle, and IDH mutations have been associated with many cancers, including glioblastoma, sarcoma, acute myeloid leukemia, etc. Three natural steroids 1-3 from Ganoderma sinense, a unique and rare edible-medicinal fungi in China, were found as potential IDH1 inhibitors by virtual ligand screening method. Among the three compounds, 3 showed the highest binding affinity to IDH1 with significant calculated binding free energy. Enzymatic kinetics demonstrated that 3 inhibited mutant enzyme in a noncompetitive manner...

Severely immunocompromised patients are at increased risk for uncommon infectious diseases with atypical presentations. Fusarium sp., has been reported in patients with hematological malignancies and prompt diagnosis is necessary due to high mortality. We report a myelodysplastic syndrome (MDS) patient who presented Fusarium solani infection associated with granulocytic sarcoma as an initial presentation of acute myeloid leukemia (AML) transformation. We performed histological examination, immunohistochemistry analysis, culture of the biopsy tissue and DNA sequencing to make a conclusive diagnosis of F...

Background/aim: Insulin-like growth factor-1 receptor (IGF-1R) is a pivotal receptor tyrosine kinase involved in the cell cycle and malignant tumor transformation. It is differentially expressed in various types of tumors. We aimed to determine the expression of IGF- 1R in different pediatric tumors and to shed light on possible new indications of anti-IGF-1R treatment approaches. Materials and methods: A total of 147 specimens were analyzed according to their expression of IGF-1R. Specimens included those from rhabdomyosarcomas, Wilms tumors, Ewing sarcoma/primitive neuroectodermal tumors, peripheral neuroblastic tumors, acute lymphoblastic lymphoma, Hodgkin lymphoma, Burkitt lymphoma, retinoblastoma, pleuropulmonary blastoma, Langerhans cell histiocytosis, endodermal sinus tumors (ESTs), and myeloid sarcoma...

Robert Roskoski
The Kit proto-oncogene was found as the consequence of the discovery of the feline v-kit sarcoma oncogene. Stem cell factor (SCF) is the Kit ligand and it mediates Kit dimerization and activation. The Kit receptor contains an extracellular segment that is made up of five immunoglobulin-like domains (D1/2/3/4/5), a transmembrane segment, a juxtamembrane segment, a protein-tyrosine kinase domain that contains an insert of 77 amino acid residues, and a carboxyterminal tail. Activating somatic mutations in Kit have been documented in various neoplasms including gastrointestinal stromal tumors (GIST), mast cell overexpression (systemic mastocytosis), core-binding factor acute myeloid leukemias (AML), melanomas, and seminomas...

Myeloid sarcoma is an extramedullary tumor that consists of myeloblasts or immature myeloid cells. The neoplasm can occur in any part of the body, including the bone, periosteum, lymph nodes, skin, and soft tissue and they may occur de novo or in association with acute myeloid leukemia, myeloproliferative neoplasms and myelodysplastic syndromes. Most cases display a myelomonocytic or pure monoblastic morphology. Tumors with megakaryoblastic differentiation are extremely uncommon and may occur in association with transformation of a myeloproliferative disorder...

Myeloid sarcoma is an extramedullary (EM) manifestation (i.e., manifestation outside the bone marrow) of acute myeloid leukemia (AML); it is assumed to be relatively uncommon and can be the only manifestation of leukemia relapse after allogenic stem cell transplantation (allo-SCT). An EM sarcoma can manifest in any part of the body, although preferentially manifesting in immunological sanctuary sites as a single or multiple tumors. The development of myeloid sarcoma after allo-SCT is associated with certain cytogenetic abnormalities, developing of graft versus host disease (GVHD), and treatment with donor lymphocytes infusion (DLI)...

Acute myeloid leukemia (AML) is associated with frequent hospitalizations. We evaluated factors associated with length of stay (LOS) and charge per day (CPD) for admissions in older (≥60 years) and younger patients (<60 years). We identified patients with ICD-9-CM codes for AML or myeloid sarcoma in the 2012 HCUP-NIS. In separate models based on age, we examined patient (sex, race, income, insurance payer, chronic conditions, chemotherapy administration, death) and hospital (type, geography) characteristics...

Myeloid sarcoma (MS) is a rare condition and is an extramedullary tumour of immature myeloid cells. It is now known that the programmed death 1 (PD-1)/programmed death ligand 1 (PD-L1) pathway suppresses the host antitumor responses and that these products are expressed on both tumour cells and tumour-infiltrating cells in various malignancies. However, little is known about the significance of PD-1/PD-L1 expression on tumour cells and tumour microenvironmental cells in MS. To investigate the clinicopathological significance of PD-1/PD-L1 expression in MS, we analyzed 98 patients by immunohistochemistry...

We report a case of myeloid sarcoma with multifocal skeletal involvement, including the greater wing of the sphenoid bone. A 23-month-old boy presented with left-sided proptosis and fevers, and was found to have an infiltrative mass involving the left sphenoid bone on orbital imaging. Full body imaging further demonstrated multiple bony lesions in the pelvis, thoracic and lumbar vertebrae, bilateral femura, and left humerus, and biopsies of the humerus were consistent with myeloid sarcoma. The patient was started on a standard chemotherapy regimen and is responding well...

Patients following solid organ transplantation show a higher risk of developing cancer compared to the general population. Elevated risk is likely due to the interplay of a combination of factors, such as chronic inflammation, coexisting medical conditions, immunosuppressive regimen and persistent infection with oncogenic viruses. In addition, the tumor microenvironment plays a pivotal role in cancer progression, by driving recruitment and in situ differentiation of anti-inflammatory cells of the adaptive and innate immune system such as regulatory T cells, Th17, Dendritic Cells, Myeloid Derived Suppressor Cells, Type 2 Macrophages...
