[What is confirmed in the treatment of colon cancer?].

Colorectal cancer is the second most common cancer diagnosed in Germany and is the third most frequent cause of cancer-related death in both males and females. The majority of colorectal cancers occur via the adenoma-carcinoma sequence of origin. This means that colorectal cancers can be endoscopically detected in premalignant stages and can be curatively treated within the framework of early detection. Screening colonoscopy and, to a lesser extent, fecal occult blood testing, have led to a reduction in the colon cancer-related incidence and mortality. The acceptance and the use of screening colonoscopy should therefore be developed further. Treatment strategies for colorectal cancer are based on TNM staging, supplemented by anatomical and histopathological risk features as well as individual patient characteristics and treatment preferences. The molecular tumor profile is increasingly used to complement decision-making in the surgical, adjuvant and palliative treatment of colorectal cancer. Colon and rectal cancer have many similarities; however, they differ in the preoperative, surgical and adjuvant treatment strategies. This article focuses on colon cancer.
