Title
Inflammatory potential of diet and survival of colorectal cancer in the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial
Summary
As one of the most five commonly cancers, colorectal cancer causes large disease burden. More than 104,000 new cases of colon cancer and 43,340 new cases of rectal cancer were diagnosed in the United States in 2020. Evidence suggests a role for the ability of diet to modulate inflammation in the etiology of this disease. A typical human diet included both proinflammatory and anti-inflammatory foods and nutrients. Therefore, a dietary pattern approach, which provides insights into the complex interactions among dietary components, may guide dietary intervention strategies aimed at the primary prevention of this malignancy. Previously studiy had examined the association between dietary inflammatory index (DII) score and risk of mortality of colorectal cancer patients.
Our current objective is to examine the association between inflammatory potential of diet, as estimated by the DII, and colorectal cancer survival using data from the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial prospective cohort. The PLCO is a well characterized and diverse study population with large number of cancer cases that would provide ample power.
Aims

To examine the association between inflammatory potential of diet, as estimated by the DII, and colorectal cancer survival using data from the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial prospective cohort.
