了解门诊患者对结直肠癌及其筛查认知程度和筛查意愿，为提高结直肠癌筛查率提供依据。

向广州地区某家综合性医院门诊患者随机发放自制问卷，对其结直肠癌的认知程度及筛查意愿和相关影响因素进行调查。

共216例门诊患者纳入研究，其中高学历组（高中、中专及以上学历）96例（44.4%），低学历组（初中及以下学历）120例（55.5%）。对结直肠癌认知程度高学历组是低学历组的1.8倍（83.3% vs 46.7%，P < 0.01）。比起高学历组，低学历组患者对结直肠癌相关筛查手段、大便潜血检查、肠镜更缺乏认识（均P < 0.05）。晚期发现结直肠癌预后差、早发现则生存概率高的问题上，高学历组比低学历组患者更认同（75.0% vs 40.0%，P < 0.01）。如果得到医师推荐，高学历组比低学历患者更愿意接受大便潜血检查（79.2% vs 66.7%，P < 0.05）。

门诊患者对结直肠癌及其筛查认知程度偏低，其中低学历患者对结直肠癌的认识尤为不足。在结直肠癌筛查的相关宣传中，要侧重对低学历患者的宣教。

To investigate the knowledge of colorectal cancer and willingness to receive colorectal cancer screening among outpatients, and to provide the basis for improving the current situation of CRC screening.

With random sampling, outpatients in a comprehensive hospital were analyzed by self- designed questionnaire about the information of colorectal cancer. χ² test analysis were used by SPSS 20.0.

Two hundred and sixteen outpatients were investigated, among which 96 outpatients (44.4%) had got better education than nine years of compulsory education, while 120 outpatients (55.5%) had got lower education. Outpatients with higher education, were 1.8 times as likely to have heard about colorectal cancer (83.3% vs 46.7%, P<0.01). Compared to the patients who had got better education, patients with lower education knew less about screening tests, fecal occult blood testing and flexible sigmoidoscopy (all P < 0.05). Compared to the patients who had got lower education, better educated patients believed that colorectal cancer is serious if found late and chances of survival are good to excellent if found early (75.0% vs 40.0%, P < 0.01). Patients with better education would more likely to use a fecal occult blood testing kit if their surgeon recommended it (79.2% vs 66.7%, P < 0.05).

Outpatients in Guangzhou were lack of knowledge about colorectal cancer and colorectal cancer screening, especially the patients with lower education. It is important to strengthen the health education of patients with lower education.
