Notes:

In Situ Stage represents the presence of malignant cells within the cell group from which they arose, with no penetration of basement membrane of the tissue and no stromal invasion.
Localized Stage represents invasive cancer confined to the organ of origin or intralumenal extension where specified as an intralumenal extension to immediately contiguous segments of the large bowel.
Regional Stage represents direct extension to adjacent organs or tissues or involvement of the regional lymph nodes.
Distant Stage represents direct continuity to non-adjacent organs, discontinuous metastasis or involvement of the distant lymph nodes.
COVID-19 Pandemic: In 2020, the highly publicized impact of the COVID-19 pandemic on health services and the consequential delays and reductions in cancer screening and diagnosis led to a decline in the 2020 incidence rates for most cancer sites. Because 2020 was a temporary, anomalous year, it can bias estimates such as cancer incidence trends.
