目的 分析飞行人员大肠癌患者的临床特征,提高飞行人员大肠癌的诊治水平.方法 回顾性分析2006年1月—2016年11月空军总医院诊治的11例飞行人员大肠癌患者的临床及病理资料.结果 本组最常见症状为血便,发病年龄35~52岁,中位年龄44岁,中位飞行时间3000 h,好发部位主要位于直肠,组织学类型以溃疡型腺癌为主,病理类型以中分化腺癌最多见.飞行时间与年龄、淋巴结转移、肿瘤大小及组织学类型相关,分化程度与神经侵犯相关,淋巴结转移除与脉管癌栓相关,肿瘤大小与肿瘤部位有关.结论 飞行人员大肠癌确诊时分期较晚,必须加强对大肠癌早期临床症状的宣传和对年龄及飞行时间存在高位因素的飞行人员进行常规普查,早发现、早诊断、早治疗,提高生存率.“,”Objective To analyze the clinical features of flying personnel with colorectal cancer and improve the diagnosis and treatment of colorectal cancer. Methods The clinical and pathological data of 11 flying personnel with colorectal were retrospectively analyzed from January 2006 to November 2016. Results The most common symptoms were bloody stool, age 35-52 years, median age 44 years, median flight time 3000 hours, predilection sites mainly in the rectum, histological type of ulcerative adenocarcinoma, moderately differentiated adenocarcinoma is the most common pathological type. The time of flight is related to age, lymph node metastasis, tumor size and histological type. The degree of differentiation is related to nerve invasion. Lymph node metastasis is related to tumor thrombus, and tumor size is related to tumor site. Conclusion The diagnosis of colorectal cancer staging of flight personnel was late, the early warning of early clinical symptoms of colorectal cancer and the high risk factors for age and flight time must be strengthened, early detection, early diagnosis and early treatment, improve survival rate.
