ObjectivesThe present study aims to report the incidence of colorectal cancer patients under 50 years of age and to compare its aggressiveness with colorectal cancer patients over 50 years of age.BackgroundRecently, the incidence of colorectal cancer at younger ages has increased, and colorectal cancers in young people have a more aggressive course due to late screening programs.MethodThe files of patients who were operated for colorectal cancer were reviewed retrospectively. Information on the patients such as gender, age, BMI, type and duration of symptoms, location of the tumor, TNM staging, pathology results, operative procedure, morbidity and mortality rates were recorded. Admission complaints, symptom onset time, tumor locations, pathological findings and tumor stages were compared between patients under and over the age of 50.ResultsThe incidence of colorectal cancer under 50 was 21 % (56/267). The age group of 40‒49 was found to be the most common age range under the age of 50, with a colorectal cancer rate of 68%. In patients under the age of 50, higher invasion of the tumor to the serosa, low differentiation of the tumor in terms of histological findings in a higher number of patients and higher mucin component of the tumors and higher N2 lymph node involvement ratio and the tumor was located more in the lower rectum were statistically significant when compared to patients over the age of 50 (p=0.026, p=0.018, p=0.002, p=0.042, p=0.006; respectively).ConclusionThe incidence of colorectal cancer has increased at younger ages and has a more aggressive course. Screening programs should be modified (Tab. 4, Fig. 2, Ref. 45).
