Maria Elena Martinez, PhD, MPH, on Colorectal Cancer Screening in Underserved Populations: COVID, Silver Linings, and Challenges Ahead
AACR Annual Meeting 2022
Maria Elena Martinez, PhD, MPH, of the University of California, San Diego Moores Cancer Center, provides an overview of the key components of the Accelerating Colorectal Cancer Screening and Follow-up through Implementation Science program, challenges posed by the COVID-19 pandemic, and opportunities for overcoming these challenges. Although screening and follow-up may reduce the incidence of and mortality from colorectal cancer, these disparities persist in medically underserved populations (Abstract SY30).

Josh Neman, PhD, of the Keck School of Medicine, University of Southern California, discusses the distribution of brain metastasis to preferential brain regions that vary according to cancer subtype, how neurotransmitters respond, and the ways in which the central nervous system acclimates (Abstract SY32).

Alana L. Welm, PhD, of the University of Utah Huntsman Cancer Institute, discusses her findings of a new pathway that regulates the antitumor immune response during metastatic outgrowth. Interfering with a particular isoform of RON kinase may cause metastatic tumors to be swarmed by T cells and killed, suggesting that new approaches to targeting this kinase may be achievable in the near future (Abstract SY32).

Nickolas Papadopoulos, PhD, of the Sidney Kimmel Comprehensive Cancer Center, discusses early detection as the key to reducing cancer mortality and the lack of tests for many malignancies. Liquid biopsies have the potential to screen for various tumor types, albeit with varying levels of sensitivity. Dr. Papadopoulos discusses his research on such blood tests, following patients prospectively to find the best combination of genetic and epigenetic biomarkers to increase sensitivity (Abstract PL02).

Iván Márquez-Rodas, MD, PhD, of Spain’s Hospital General Universitario Gregorio Marañón, discusses final results of the phase II SPOTLIGHT203 study of systemic pembrolizumab in combination with intratumoral BO-112 for patients with advanced melanoma refractory to anti–PD-1–based therapy. The regimen achieved an overall response rate of 25% and a disease control rate of 65% (Abstract CT014).

Silvia C. Formenti, MD, of Weill Cornell Medicine, discusses research on the best way to integrate radiotherapy with immune modifiers, which might require changes in standard radiation oncology practices. Variables such as the type of treatment fields, the inclusion of draining nodal stations, the degree of exposure of circulating immune cells, the type of dose fractionation, and the timing of radiotherapy during immune checkpoint blockade all can affect the success of immunoradiotherapy combinations (Abstract SY43).
