High-grade colon cancer is associated with worse outcomes compared to low-grade disease, according to a study of over 900 colon cancer patients. The study found that high-grade colon cancer doubled the risk of lymph node and distant metastasis compared to low-grade disease. Patients with high-grade colon cancer also had double the risk of colon cancer-related mortality, even after accounting for disease stage. High tumor grade was identified as an independent factor that significantly influences colon cancer outcomes and mortality.

2. Introduction
• Tumor grade is a cardinal surgical pathological
characteristic of any malignancy.
• High-grade disease invariably has a negative
impact on the eventual outcomes of the
concerned malignancy.
• We aimed to measure the magnitude of its
influence as well as its stage-independent effect
in colon cancer.
3. Methods
• Included:
• Surgical colon cancer patients at MGH 2004-2011 with known
disease grade (n=961)
• Comparison
• Baseline pathology:
• RR of nodal and distant metastasis
• Outcomes:
• Risk of recurrence,
• Overall and disease-specific mortality
• Statistical analysis
• Ordinal: χ2
, continuous: Mann Whitney U
• Multivariate: logistic regression, AJCC-adjusted
5. Conclusions
• High-grade disease on baseline colon cancer surgical
pathology is associated with a considerably higher rate
of nodal and distant metastasis.
• Colon cancer-related mortality doubles for patients with
high-grade disease.
• All of these findings were shown to be independent of
baseline staging.
High tumor grade is a stage-independent factor greatly
influencing colon cancer outcomes and mortality.
