We quantified the lifetime impact of CRC and its variation by SEP, using individualised income to conceptualise SEP.  \nMethods Data included all adults with a first-time diagnosis of colon or rectal cancers in Sweden between 2008 and 2021. The analysis was done separately for colon and rectal cancers using flexible parametric models. For each cancer and income group, we estimated the life expectancy in the absence of cancer, the life expectancy in the presence of cancer and the loss in life expectancy (LLE) .  \nResults We found large income disparities in life expectancy after a cancer diagnosis, with larger differences among the youngest patients. Higher income resulted in more years lost following a cancer diagnosis. For example, 40-year-old females with colon cancer lost 17.64 years if in the highest-income group and 13.68 years if in the lowest-income group. Rectal cancer resulted in higher LLE compared with colon cancer.  \nMales lost a larger proportion of their lives. All patients, including the oldest, lost more than 30% of their remaining life expectancy. Based on the number of colon and rectal cancer diagnoses in 2021, colon cancer results in almost double the number of years lost compared with rectal cancer (24 669 and 12 105 years, respectively) . Conclusion While our results should be interpreted inline with what individualised income represents, they highlight the need to address inequalities.  \nBACKGROUND  \nColorectal cancer (CRC) is the third most common cancer worldwide and the second most common cause of cancer-related deaths.1 The overall incidence of CRC decreased in the last years or remained almost constant, but for patients under 50 years old, the incidence continued to increase over time both in Sweden2 and other countries.3–5 Screening programmes are implemented in some countries; however, these are generally offered to those above 50 years old and could not justify the increase in incidence.  \nCRC survival has improved substantially in many countries.6–8 Nevertheless, several studies have reported disparities in survival by socioeconomic position (SEP).9–11 The differences persist  \n\n| WHAT IS ALREADY KNOWN ON THIS TOPIC |\n| --- |\n| ⇒ Differences in the prognosis after colorectal cancer (CRC) by socioeconomic position have been reported previously; however, most studies focused on survival differences at a partic","cbCaiuTa1SmnRB9L","https://ap.wps.com/l/cbCaiuTa1SmnRB9L","pdf",1084432,"English","# Abstract\n# Background\n# What is already known on this topic\n# What this study adds\n# How this study might affect research, practice or policy","[{\"question\":\"What question does the study address about colorectal cancer and socioeconomic position?\",\"answer\":\"It examines how the lifetime loss in life expectancy after colon or rectal cancer varies by socioeconomic position (SEP), operationalised using individualised income.\"},{\"question\":\"How did the researchers estimate life expectancy loss after diagnosis?\",\"answer\":\"They calculated life expectancy in the absence of cancer, life expectancy with cancer, and the resulting loss in life expectancy (LLE), using flexible parametric models separately for colon and rectal cancers.\"},{\"question\":\"What were the main findings regarding income and cancer type?\",\"answer\":\"Higher income was associated with more years lost after diagnosis, with larger disparities among younger patients.
