Emerging Trends in Cancer Prevention Agent Development

Advances in omics and immunology over the past 20 years have revolutionized the approach to cancer prevention, with the goal now focused on identifying populations at higher risk for developing cancer in their lifetime as a result of either extensive exposure to environmental carcinogens or harboring precancer lesions or inherited genetic mutations that predispose them to specific types of cancer(s). Thus, the naïve idea that cancer could be “prevented” in the general population has evolved to a more practical approach based on the understanding that the target population for preventive agents will be individuals who already have alterations, in gene pathways, whether inherited or environmentally caused, and the goal will be to “intercept” these lesions at the earliest stages in the path from an initial genetic lesion to full-blown cancer. The Division of Cancer Prevention of the National Cancer Institute and the Office of Disease Prevention at the National Institutes of Health recently sponsored the second biennial “Translational Advances in Cancer Preventive Agent Development Meeting,” held virtually from September 7–9th. In this Meeting Report, we highlight the scientific sessions of this meeting that covered the most recent advances in preventive agent development that also highlighted these rapidly emerging trends in this research area.

Meeting Report: Translational Advances in Cancer Prevention Agent Development Meeting

The Division of Cancer Prevention of the National Cancer Institute (NCI) and the Office of Disease Prevention of the National Institutes of Health co-sponsored the Translational Advances in Cancer Prevention Agent Development Meeting on August 27 to 28, 2020. The goals of this meeting were to foster the exchange of ideas and stimulate new collaborative interactions among leading cancer prevention researchers from basic and clinical research; highlight new and emerging trends in immunoprevention and chemoprevention as well as new information from clinical trials; and provide information to the extramural research community on the significant resources available from the NCI to promote prevention agent development and rapid translation to clinical trials. The meeting included two plenary talks and five sessions covering the range from pre-clinical studies with chemo/immunopreventive agents to ongoing cancer prevention clinical trials. In addition, two NCI informational sessions describing contract resources for the preclinical agent development and cooperative grants for the Cancer Prevention Clinical Trials Network were also presented.

Translational Advances in Cancer Prevention Agent Development (TACPAD) Virtual Workshop on Immunomodulatory Agents: Report

The National Cancer Institute (NCI) Division of Cancer Prevention (DCP) convened the “Translational Advances in Cancer Prevention Agent Development (TACPAD) Workshop on Immunomodulatory Agents” as a virtual 2-day workshop on September 13 to 14, 2021. The main goals of this workshop were to foster the exchange of ideas and potentially new collaborative interactions among leading cancer immunoprevention researchers from basic and clinical research and highlight new and emerging trends in immunoprevention. The workshop included an overview of the mechanistic classes of immunomodulatory agents and three sessions covering the gamut from preclinical to clinical studies. The workshop convened individuals working in immunology and cancer prevention to discuss trends in discovery and development of immunomodulatory agents individually and in combination with other chemopreventive agents or vaccines.

COVID-19 in Children with Brain-Based Developmental Disabilities: A Rapid Review

BackgroundThe prevalence of symptomatic COVID-19 in children remains low to date. In just a few months, COVID-19 has affected millions of people worldwide, and as of the date of this publication, the pandemic continues. Based on the current available evidence, children do not appear to be at higher risk of contracting COVID-19 than adults. However, children with neurological and neuromuscular conditions are vulnerable to the respiratory complications of other viral infections. ObjectivesTo assess whether children with brain-based developmental disabilities were more likely to develop COVID-19 and have complications or poorer outcomes following infection. MethodsWe conducted a two-week rapid review on studies with primary data regarding children aged between zero and 18 years old with brain-based developmental disabilities, or who were at risk of developing such disabilities, with confirmed or suspected COVID-19. We performed our literature searches on April 18, 2020. ResultsOur search strategy identified 538 individual records, of which four were included in our review. Of the 50 COVID-19 pediatric patients reported in the included studies, a total of seven children were at risk of developing brain-based disabilities. Symptoms ranged in severity. However, generally, patients were discharged or saw improvements in their symptoms by the end of the study period. No deaths were reported. DiscussionOur study highlights a knowledge gap regarding the impact of COVID-19 in children with brain-based developmental disabilities.

Rapid Detection of 2019 Novel Coronavirus SARS-CoV-2 Using a CRISPR-based DETECTR Lateral Flow Assay

An outbreak of novel betacoronavirus, SARS-CoV-2 (formerly named 2019-nCoV), began in Wuhan, China in December 2019 and the COVID-19 disease associated with infection has since spread rapidly to multiple countries. Here we report the development of SARS-CoV-2 DETECTR, a rapid ([~]30 min), low-cost, and accurate CRISPR-Cas12 based lateral flow assay for detection of SARS-CoV-2 from respiratory swab RNA extracts. We validated this method using contrived reference samples and clinical samples from infected US patients and demonstrated comparable performance to the US CDC SARS-CoV-2 real-time RT-PCR assay.

Concomitant Use of Panobinostat and Reirradiation in Progressive DIPG: Report of 2 Cases.

Diffuse intrinsic pontine glioma (DIPG) remains a devastating disease. Panobinostat has been shown to have therapeutic efficacy both in vitro and in DIPG orthotopic xenograft models; however, clinical data in patients with DIPG are lacking. We present 2 cases of DIPG, who were treated with panobinostat at 22 to 25 mg/m/dose, 3 times weekly for 2 weeks in 3-week cycles and concomitant reirradiation after disease progression. Two episodes of asymptomatic thrombocytopenia were observed in 1 patient. Hyperacetylation of histone H4 of peripheral blood mononuclear cells was evident following treatment. In our experience, panobinostat administered with reirradiation was well tolerated at a relatively higher dose than that used in adult studies.

Cómo evitar el genocidio genético: el complejo diálogo entre la comunidad biomédica y el mundo de la discapacidad / No disponible

La relación entre las comunidades relacionadas con la medicina y la discapacidad es compleja, y está condicionada por factores históricos, sociales y culturales. Aunque los médicos, los investigadores biomédicos y las personas con discapacidad trabajan todos ellos con su vista puesta en el mejor interés de los individuos con discapacidad, el concepto de lo que realmente es “lo mejor” se entiende a menudo de forma muy diferente por parte de todos estos grupos. Las campañas eugenésicas, las restricciones legales sobre la libertad reproductiva y otras libertades, y las recomendaciones de diagnóstico prenatal, expuestas en razón del menor “valor” de las personas con discapacidad, todas ellas han contribuido a crear un trauma histórico que es experimentado por la comunidad relacionada con la discapacidad, especialmente en lo que concierne a la genética médica. Una premisa de la medicina individualizada es que los distintos individuos requieren soluciones distintas. Las experiencias de las personas con discapacidad nos recuerdan que, como mejor se alcanzan estas soluciones, es manteniendo conciencia y sensibilidad dentro del complejo terreno ético y social. Los profesionales de la genética deben caer en la cuenta que su investigación puede tener implicaciones para las personas con discapacidad; deben reconocer el impacto del trauma histórico provocado por el movimiento eugenésico, y han de intentar implicar al mundo de la discapacidad en los análisis sobre las políticas que le afectan. El diálogo puede ser enmarañado y molesto, pero es el único modo de evitar las equivocaciones del pasado y de asegurar un futuro más equitativo y saludable (AU)
