Korean Colorectal Cancer Risk and Fasting Glucose Cohort 1993-2012

Korean Multi-center Cancer Cohort data from 1993 to 2005 tracks 14,570 adult participants with a median follow-up of 11.9 years for colorectal cancer incidence. The dataset contains information on fasting serum glucose levels, self-reported diabetes history, and hazard ratios for cancer risk. It was analyzed by Hyeree Park to investigate associations between glucose control and colorectal cancer.

Use Cases

• Analyze the association between fasting serum glucose levels (≥126mg/dL vs. <126mg/dL) and colorectal cancer incidence using provided hazard ratios.
• Compare colorectal cancer risk between participants with self-reported diabetes history and those without, controlling for fasting glucose status.
• Investigate the combined effect of high fasting serum glucose and no self-reported diabetes history on colorectal cancer risk over long-term follow-up.
• Examine temporal patterns by excluding the first 5 years of follow-up to assess latency in risk associations for high fasting glucose groups.

Strengths

• Substantial cohort of 14,570 participants providing a solid basis for longitudinal analysis.
• Long median follow-up period of 11.9 years, enabling the study of long-term cancer risk.
• Data includes clinically relevant measures like fasting serum glucose levels and self-reported medical history.

Limitations

• Sample data and specific column structure are unavailable, limiting understanding of the raw data format and variables.
• The dataset is focused on a Korean population, which may limit generalizability to other ethnic or geographic groups.
• Data collection ended in 2005 with follow-up until 2012, making the findings potentially less reflective of current medical practices.
