Association Between Dietary Calcium Intake and the Prognosis of Colorectal Cancer Survivors: A Prospective Cohort Study

Objectives: Calcium has been shown to reduce the toxic effects on epithelial cells by binding ionized fatty acids and secondary bile acids in the colon, thereby protecting against colorectal cancer (CRC). However, few studies have examined the association between dietary calcium intake and survival in CRC patients. This study aimed to explore the relationship between dietary calcium intake and overall survival, CRC-specific survival, disease-free survival and metastasis-recurrence risk among CRC survivors.
