Abstract

Research on precancers, as defined as at-risk tissues and early lesions, is of high significance given the effectiveness of early intervention. We discuss the need for risk stratification to prevent overtreatment, an emphasis on the role of genetic and epigenetic aging when considering risk, and the importance of integrating macroenvironmental risk factors with molecules and cells in lesions and at-risk normal tissues for developing effective intervention and health policy strategies.

Figure 1.. The hallmarks of precancer.
Studies on precancers have identified a set of 6 cellular/molecular traits consistently observed across various tissue types. Starting at the top center wedge of the ring and proceeding clockwise, these are: 1) age-related genetic alterations including telomere shortening and somatic mutations; 2) epigenetic changes resulting from aberrant methylation at specific sites; 3) metabolic alterations; 4) hijacking of regenerative cell state transitions; 5) disruption of immune surveillance and “inflammaging”; and 6) remodeling of the tissue microenvironment mediated by senescent fibroblasts.

Figure 2.. Integration of multiomics analyses with patient metadata to understand how macroscopic risk factors influence molecular pathways.
Advancing our knowledge of the cellular and molecular interactions that contribute to the formation and progression of precancers is essential as we build towards a cancer-free world. We propose integrative analysis of patient metadata with next-generation multiomics to enhance our understanding of how macroenvironmental exposures molecularly affect cells and biological pathways.
