Minority populations with CRC are known to have worse survival outcomes. The aim of this study is to evaluate adults under age 50 years with CRC by race and ethnicity.MethodsData were obtained from all US hospitals that contributed to the National Cancer Database (NCDB) between 2004 and 2013. Univariate and multivariable testing was done to identify factors associated with patient outcome. Kaplan-Meier analysis and Cox proportional hazards models were used for association between patient characteristics and survival.ResultsA total of 83,449 patients between 18 and 50 years of age were identified. Median age was 45 years (SD ± 6), with male preponderance (53.9%). 72% were non-Hispanic Whites (NHW), Blacks (AA) were 15.1% and Hispanics (who did not identify as Blacks) were 8.3% of the study population. Distribution across stages IIV was 15.6%, 22.4%, 33.9% and 27% consecutively. 41.8% of NHW and 28.4% of AA had rectal cancers (p
Conclusions: We found age-related disparities in CRC incidence and IBM between individuals under age 50 and age 50 years and older. Increasing incidence rates of rectal cancer substantially accounts for this disparity among individuals under age 50. The escalating trends of early-onset CRC warrant investigation into the factors leading to the population-level trends. PMID: 31827515 [PubMed]
In conclusion, colorectal cancer in young adults occurs without obvious risk factors in Burkina Faso. Mortality remains high because of the limited therapeutic arsenal. PMID: 31615647 [PubMed - as supplied by publisher]
In contrast to the decreasing incidence of colorectal cancer (CRC) in older populations, the incidence has nearly doubled in younger adults since the early 1990s. Approximately 1 in 10 new diagnoses of CRC are now made in individuals 50 years or younger. Patients ’ risk of CRC has been calculated largely by age and family history, yet 3 of 4 patients with early-onset CRC have no family history of the disease. Rapidly increasing incidence rates in younger persons could result from generational differences in diet, environmental exposures, and lifestyle fact ors.
(The Lancet) The incidence of colon and rectal cancer in adults younger than 50 years has increased substantially over the latest available 10-year period in several high-income countries, going against a decline or stabilisation trend in the incidence of colorectal cancers within the overall populations of high-income countries.
In this study, we reviewed major human studies on the health risks of radiation exposure and showed that sex-related factors may potentially influence the long-term response to radiation exposure. Available data suggest that long-term radiosensitivity in women is higher than that in men who receive a comparable dose of radiation. The report on the biological effects of ionizing radiation (BEIR VII) published in 2006 by the National Academy of Sciences, United States emphasized that women may be at significantly greater risk of suffering and dying from radiation-induced cancer than men exposed to the same dose of radiation....
The Young-Onset Colorectal Cancer Center is among the first centers in the country dedicated to treating colon and rectal cancer patients under age 50
There has been significant publicity recently regarding increasing rates of colorectal carcinoma (CRC) in young patients aged 20 to 45 years. Last year in the Journal of the National Cancer Institute, a publication by Siegel et al1 entitled “Colorectal cancer incidence patterns in the United States, 1974-2013” demonstrated that young adults now have double the risk for the development of colon cancer and quadruple the risk for the development of rectal cancer, compared with their age-matched counterparts born in 1950 .
Opinion statementColorectal cancer (CRC) is the third most common cancer worldwide. CRC has been thought to be less common in Asia compared to Western countries. However, the incidence rates of CRC in Asia are high and there is an increasing trend in the Asian population. Furthermore, colorectal cancer accounts for the greatest number of all incidences of CRC in Asia. The increasing adoption of a Western lifestyle, particularly in dietary habits, is likely the most important factor contributing to the rapid increase in colon cancer incidence; it is noteworthy that trends for rectal cancer were flat. The etiology of colon a...
This study didn’t measure why colorectal cancer was rising in younger people, but the scientists did dive into past research on the subject to came up with a few theories. Colorectal cancer risk is linked to excess body weight, cigarette smoking and the consumption of lots of alcohol and highly processed meat. At the same time, eating little fiber and a sedentary lifestyle are also linked to a higher risk of colorectal cancer. While it’s true that younger generations smoke and drink less than baby boomers, they also weigh more, and at younger ages. This prolonged obesity could be a clue, Siegel and her co...
Younger Americans are now facing a higher risk of getting colon and rectal cancer, according to a new study. New cases are striking adults in their 20s and 30s, while cases among Americans 55 and older are declining. Dr. Jon LaPook reports.
