In a recent study published in Gut, an authoritative journal on digestive diseases, researchers aim to provide the latest estimates of the survival rates of colon and rectal cancer patients in seven high-income countries based on age and diagnostic stages as part of the International Partnership for the Evaluation of Cancer Benchmarking (ICBP) SURVMARK-2 projectresearchers analyzed data on 386,870 patients diagnosed in 19 cancer registry centres in seven countries (Australia, Canada, Denmark, Ireland, New Zealand, Norway and the United Kingdom) between 2010 and 2014Net survival rates for colon and rectal cancer patients were assessed for 1 and 5 years based on diagnostic phases, age and countrycolon and rectal cancer (1 year) and 5 years of net survival rates were between 59.1% and 70.9% (77.1% to 87.5%) and (84.8 to 90.0%) between 61.6% and 70.9%In Australia, Canada and Norway, patient survival rates have been high, and in Canada and Australia, the proportion of patients with metastatic diseases is smallerThe international differences in survival rates for regional and distant colon cancer patients (1 year) and 5 years were most pronounced, ranging from 62.5 to 77.5 per cent (86.0 to 94.1 per cent) and 8.0 to 17.3 per cent (40.7 to 56.4 per cent)Similar results were observed for rectal cancerThe staging distribution of colon and rectal cancer varies from country to country, and the survival rate of patients with older diseases and diagnosis (regardless of staging) varies significantlyIn some high-income countries, differences in survival for colon and rectal cancer patients may be due to early diagnosis, differences in the treatment of regional and distant diseases, and older age at the time of diagnosis in some countriesDifferences in cancer registration practices and different staging systems may affect comparisons
