Survivors of childhood cancer are at excess risk of late mortality even 40 years from diagnosis

According to the Childhood Cancer Survivor Study (CCSS) cohort, "long-term survivors of childhood cancer are at four times the risk of death compared with the general, ageing population." Particularly in the 5-9 year survival period after diagnosis, health-related causes of death include heart disease, cerebrovascular disease, influenza, pneumonia, sepsis, and kidney failure, conditions normally attributable to a diagnosis during middle age.

New study shows more deaths with cancer as contributing cause during first year of pandemic

A new study unveiled by the American Cancer Society indicates that "individuals living with cancer were at higher risk of COVID-19 infection and experiencing more severe symptoms due to their health conditions and treatment-related immune suppression." Jingxuan Zhao, senior associate scientist and lead researcher in the study further explains that strict pandemic measures, especially orders to stay at home, along with a pause of non-emergency treatment had a different effect on delays in cancer screening, diagnosis, and treatment.

Helicobacter Pylori infection modifies the risk of gastric cancer associated with germline pathogenic variants in homologous recombination genes

A joint Japanese and Australian cohort study, led by the RIKEN Center for Integrative Medical Sciences in Yokohama, indicated that "pathogenic variants and Helicobacter pylori infection interacted to markedly increase the risk of gastric cancer..." According to lead researcher Dr. Yukihide Momozawa, evaluation and eradication of Helicobacter pylori is of particular importance in individuals "known to carry a pathogenic variant in a homologous recombinant gene."
