The first study to offer an overview of the incidence and mortality rates of colon cancer in Europe shows a worrisome fact: the incidence of this type of cancer is increasing in Europe among people aged 20 to 49 years. If this trend continues, say the authors of the report published in "Gut", it may be necessary to reconsider the current detection guidelines, based on population screening. And, until the cause of this situation is clarified, researchers from the University of Erasmus in Rotterdam (The Netherlands) recommend increasing awareness among healthcare professionals and identifying the factors possibly associated with this trend.
The research has used the data of 143.7 million people aged 20 to 49 from 20 European countries. In countries, such as Portugal, Spain and Italy, data was only available for a limited number of regions. In addition, not all countries were able to provide data for a period of 25 years, because some national cancer registries were subsequently created. However, in all of them, the data was available for at least 10 years.
Thus, it can be seen that between 1990 and 2016, a total of 187,918 people were diagnosed with colon and rectal cancer and there was a more pronounced increase in the number of new cases in recent years.
In this period, between 20 and 29 years of age, the incidence of cancer increased from 0.8 to 2.3 cases per 100,000 people, and the most marked increase was between 2004 and 2016, with 7.9% year. For the group of 30 to 39 years, the incidence rose less sharply than in the younger age group.
The report notes that new cases of bowel cancer grew significantly among people aged 20 to 39 in 12 countries: Belgium, Germany, the Netherlands, the United Kingdom, Norway, Sweden, Finland, Ireland, France, Denmark, the Czech Republic and Poland, while in Italy there was a decrease in the number of cases. In eight – the United Kingdom, Greenland, Sweden, Slovenia, Germany, Finland, Denmark and the Netherlands – the number of cases rose significantly among young people aged 40 to 49, but the rates decreased significantly in the Czech Republic in recent years. years (1997-2015).
Syndromes of hereditary cancer
In Spain, according to the SEOM report on Cancer in Spain, cancer of the colon and rectum will be the most diagnosed in 2019 (44,937 new cases), followed by prostate (34,394), breast (32,536), lung (29,503) and bladder. (23,819).
Last year more than 37,000 cases of colorectal cancer were diagnosed in our country, the most frequent tumor among the Spanish population and the second that causes more deaths
(15.656) despite the fact that in most cases it is cured if it is detected in time: it is exceeded in 90% of cases in which it is detected early.
Bowel cancer in young adults is "partly due to hereditary cancer syndromes, but most cases are sporadic," the researchers say.
During the last decade, the number of new cases of colon and rectal cancer has increased in most European countries, but the situation among younger adults was not clear. This work sheds light on European trends and notes that prevention may not be working. (tagsToTranslate) cancer (t) colon (t) recto (t) europa
