Abstract 7285: Gene expression-based subtypes associated with prognosis in Colombian colorectal cancer

Wendy Johana Montero Ovalle · Diego Felipe Ballen-Lozano · Liliana López-Kleine · Silvia Juliana Serrano-Gomez

Abstract In Colombia, colorectal cancer (CRC) is the fifth leading cause of cancer-related death. Molecular alterations linked to clinical-pathological variables are useful for prognosis and guiding treatment. However, current gene expression-based classifications have been developed mostly in non-Latin American popula...

In vitro synergistic activity of minocycline and biapenem against cefiderocol-resistant New Delhi metallo-β-lactamase-producing Enterobacterales

Takashi Okanda · Niinyo Nakajima · Tetsuo Yamaguchi · Takuro Koshikawa · y 5 más

Abstract Objectives Cefiderocol is an important treatment option for infections caused by multidrug-resistant Gram-negative bacteria; however, resistance among New Delhi metallo-β-lactamase-producing Enterobacterales (NDME) is increasingly reported, leaving limited therapeutic alternatives. This study evaluated the in...

Análisis de las variables dinámicas del movimiento de arranque en levantadores de pesas colombianos categoría 81 kilogramos

Kevin Johann Restrepo Hernández · Diego Andrés Rada Perdigón · David Tellez Ardila · Jesus Adolfo Morales Tamayo · y 1 más

Introduction: Performance in weightlifting depends on the interaction between dynamic variables of movement and a highly specialized technique. Nevertheless, on the Colombian context there is limited biomechanical evidence that characterizes these factors in advance competitive athletes. Objective: Identify, describe a...

Tumores estromales gastrointestinales y su asociación con otras neoplasias. Estudio de cohorte retrospectiva multicéntrico

Dánel Ruben Yarig Blanco-Guerrero · Bernardo A. Borráez-Segura · Camilo Ramírez-Giraldo · Valentina Santa-Gil · y 6 más

Introducción. Los tumores del estroma gastrointestinal son neoplasias infrecuentes, que representan aproximadamente el 80 % de los tumores mesenquimales malignos del tracto gastrointestinal. Diversos estudios han descrito la asociación con otras neoplasias, sincrónicas o metacrónicas. Esta coexistencia de múltiples pat...

Abstract 2303: Androgen receptor expression in breast cancer and its prognostic significance: A systematic review and meta-analysis

Elias Ferreira · Luis Giraldo-Barrios · Laura Suarez · Maria P. Valera · y 3 más

Abstract Background: Molecular classification of breast cancer subtypes is based on the expression of estrogen, progesterone and HER2 receptors. The androgen receptor has emerged as a biomarker however, its prognostic role remains incompletely elucidated. Objective: to determine androgen receptor expression value as a...

Abstract 7275: Molecular characterization of Latino gastric adenocarcinomas identifies homologous recombination deficiency and TGF-beta pathways as targets for aggressive genomically stable tumors

Dennis J. Montoya · Ana Patricia Estrada-Florez · Paul Lott · Katherine Chiu · y 9 más

Abstract Background: Gastric cancer (GC) disproportionately affects Latino populations, yet genomic data from these patients remain scarce. This underrepresentation limits understanding of ancestry-specific molecular features that could inform targeted therapies. Tumors characterized by a genomically stable (GS) subtyp...
