    【Abstract】 Objective To study the clinical character, surgery treatment and prognosis in 43 cases of young patients with colon cancer.Methods The clinical pathological feature and survival rate of 43 cases of young patients with colon cancer were analysed retrospectively.Results The mean duration from onset of symptoms to diagnosis in this group was 6. 2 months. 24 of 43 were misdiagnosed. The misdiagnosis rate was 55.8%. Dukes stages C and D was noted in 31 cases (72.1% ). The proportion of poorly differentiated adenocarcinoma, mucinous carcinoma was 31 cases (72.1%). The 1 - year survival rate in complete resection group was 62.7%. The 2 - year survival rate in complete resection group was 35.6%. The 5 - year survival rate in complete resection group was 25.4%.Conclusion The young patients with colon cancer have the characteristic of high misdiagnosis rate, high incidence of poor differentiation. In order to raise the survival rate, it is important for us to diagnosis and treat the young adults with colon cancer as early as we can. ......
