Detection of gene fusions in solid tumors: recommendations from a Latin American group of oncologists and pathologists.

gene fusions have been detected in more than 25 types of tumors and their prevalence is approximately 0.3% in solid tumors. This low prevalence makes identifying patients who could benefit from TRK inhibitors a considerable challenge.

Anorexia and bulimia nervosa in the practice of the paediatric dentist.

Objective: This systematic review aimed to highlight the usefulness of the clinical examination of the oral cavity for the diagnostic suspicion of anorexia (AN) and bulimia nervosa (BN), being of main interest to the paediatric dentist and paediatrician due to the early onset of symptoms in Eating Disorders (EDs).

Method: A systematic search, applying PICO question, was carried out in biomedical and other electronic databases from 2005 to 2020. Both case reports and case series of patients under 65 years of age with AN and BN were included.

Lymphotropic Viruses EBV, KSHV and HTLV in Latin America: Epidemiology and Associated Malignancies. A Literature-Based Study by the RIAL-CYTED.

The Epstein-Barr virus (EBV), Kaposi sarcoma herpesvirus (KSHV) and human T-lymphotropic virus (HTLV-1) are lymphomagenic viruses with region-specific induced morbidity. The RIAL-CYTED aims to increase the knowledge of lymphoma in Latin America (LA), and, as such, we systematically analyzed the literature to better understand our risk for virus-induced lymphoma. We observed that high endemicity regions for certain lymphomas, e.

Knowledge of oral cancer among the community served during the stomatological lesion prevention campaign conducted at Universidad Católica de Santiago de Guayaquil - Ecuador.

The aim of this study was to evaluate the level of knowledge on oral cancer and level of preventive care among the population. A descriptive cross-sectional study was performed to evaluate 408 individuals through a face-to-face survey at Universidad Católica de Santiago de Guayaquil during the 2016 academic year. Sixty-one percent (61%) of respondents said they knew of the existence of oral cancer, but 56.

Genomic imbalances and microRNA transcriptional profiles in patients with mycosis fungoides.

Mycosis fungoides is the most common type of primary cutaneous T cell lymphoma. We have evaluated CDKN2A losses and MYC gains/amplifications by FISH analysis, as well as expression of miR-155 and members of the oncogenic cluster miR-17-92 (miR17, miR18a, miR19b, and miR92a) in MF patients with advanced disease. Formalin-fixed paraffin-embedded skin biopsies from 36 patients at diagnosis, 16 with tumoral MF (T-MF), 13 in histological transformation to a large T cell lymphoma (TR-MF), and 7 cases with folliculotropic variant (F-MF), were studied.

SOXC and MiR17-92 gene expression profiling defines two subgroups with different clinical outcome in mantle cell lymphoma.

Mantle cell lymphoma (MCL) is a heterogeneous B-cell lymphoid malignancy where most patients follow an aggressive clinical course whereas others are associated with an indolent performance. SOX4, SOX11, and SOX12 belong to SOXC family of transcription factors involved in embryonic neurogenesis and tissue remodeling. Among them, SOX11 has been found aberrantly expressed in most aggressive MCL patients, being considered a reliable biomarker in the pathology.
