Title
Ultra-processed food consumption and cancer-related mortality in patients with colorectal, lung, prostate, or breast cancer: a post hoc analysis of the PLCO cancer screening trial
Summary
The number of cancer patients is rabidly increasing worldwide. In the USA, there are around 16.9 million peoples who are currently living with cancer (1). Given the huge burden of cancer patients globally, it is necessary and urgent to identify modifiable risk factors for improving the prognosis of this population.
Dietary habits have been indicated to play an important role in determining the prognosis of cancer survivors. For example, a recent meta-analysis found that high vegetable consumption was inversely associated with overall mortality in survivors of head and neck (2). Ultra-processed food consumption has been associated with an increased risk of death. However, to our knowledge, no prospective cohort study has accurately evaluated the potential association between ultra-processed food consumption and mortality in cancer patients. Hence, we sought to examine this potential association in breast, colorectal, lung, and prostate cancer patients.
