Colorectal cancer (CRC) is the second most common cancer-related death in the United States and ranks first in adults younger than 50 years. Every 3 years, the American Cancer Society reports on CRC occurrence based on incidence from population-based cancer registries and mortality from the National Center for Health Statistics. Overall, CRC incidence declined by 0.9% annually during 2013-2022 driven by decreases of 2.5% annually in adults aged 65 years and older. In sharp contrast, incidence rates increased by 3% annually in adults aged 20-49 years and by 0.4% annually in adults aged 50-64 years dominated by tumors in the distal colon and rectum. Consequently, overall rectal cancer incidence increased by 1% annually from 2018 to 2022 after decades of decline and now accounts for 32% of all CRC, up from 27% in the mid-2000s. Increasing CRC incidence in adults aged 50-64 years was confined to regional and distant-stage diagnosis (1.1%-1.3% annually during 2013-2022), likely contributing to an upturn in mortality in this age group of 1% annually since 2019 that was steepest (2.3% annually) in White individuals. Mortality has increased in adults younger than 50 years by 1% annually since 2004, whereas rates have decreased in adults 65 years and older by 2.3% annually since 2012. Despite steady progress for older adults, both CRC incidence and mortality are increasing in adults younger than 65 years who are in the prime of life, underscoring an urgent need for etiologic research to discover the cause of the rising trend. Meanwhile, morbidity and mortality could be mitigated with earlier diagnosis, through screening and educating clinicians and the general public about CRC symptoms, and greater attention to the unique needs of younger patients, including discussion about the preservation of fertility and sexual health.

Reliable, contemporary estimates of the global childhood cancer burden remain scarce, particularly in the post-coronavirus disease 2019 (COVID-19) era. By using data from the Global Burden of Disease 2021 and Global Cancer Observatory 2022 projects, the authors evaluated the childhood cancer burden at global, regional, and national levels, characterizing temporal and projected trends, and analyzed the data according to disparities by geography and socioeconomic development. From 2000 to 2021, the age-standardized incidence rate (ASIR) and the age-standardized mortality rate (ASMR) of childhood cancer declined overall (average annual percent change, -0.88 and -2.13, respectively), especially during the COVID-19 pandemic. During this period, the disparities in childhood cancer burden were mainly concentrated in countries/territories with a lower Sociodemographic Index. In 2022, an estimated 202,164 new cases and 77,182 deaths from childhood cancer occurred worldwide (ASIR and ASMR, 10.3 and 3.9 per 100,000 children, respectively). Countries/territories with higher a Human Development Index (HDI) had a higher incidence (ASIR, 8.0 [low HDI] vs. 15.3 [very high HDI] per 100,000), whereas those with a lower HDI had higher mortality (ASMR, 4.4 [low HDI] vs. 2.8 [very high HDI] per 100,000). Analyses indicated that, by 2050, there will be 204,925 projected new cases and 78,210 deaths globally, with increases only in low HDI countries/territories, exacerbating existing health inequities. Childhood cancer remains a global health challenge, with notable geographic and socioeconomic disparities. These data serve as the impetus for governments and policymakers to prioritize resources and equitable access to interventions, particularly in regions with lower levels of development, while addressing health care vulnerabilities exposed by global crises like the COVID-19 pandemic.

Genomics-and genomic testing in particular-has transformed oncology, facilitating both targeted therapies and personalized care. In pediatric oncology, unique clinical and ethical considerations arise. Compared with adults, children and adolescents are affected by more limited evidence regarding test performance, variant interpretation, and the clinical utility of genomically informed interventions. Nevertheless, genomic findings may have implications beyond the patient, affecting their parents, siblings, and other relatives and raising questions around consent, assent, privacy, and psychosocial impact. This narrative review examines how ethical dimensions of genetic and genomic testing evolve across the pediatric cancer continuum, from diagnosis and treatment through survivorship and transition to adult care. Attention is given to communication strategies, interdisciplinary support, and equity concerns that influence the responsible integration of genomic medicine. The authors also identify priority areas for future inquiry, including incorporation of children's perspectives, longitudinal approaches to recontact and reconsent, and better understanding of how genomic information affects treatment decision-making. Pediatric genetic and genomic testing in oncology holds great promise, but its benefits can only be realized through thoughtfully developed and standardized communication practices, careful ethical deliberation, and equitable implementation. By proactively addressing these issues, pediatric oncologists can harness genomic advances in ways that respect and support children and their families.
