A retrospective 10-year review of all (311) new cases of colorectal cancer at a community hospital serving a multiethnic urban population was carried out in order to study characteristics of the disease other than incidence and mortality rates. There was a striking similarity despite ethnic differences in most characteristics. The only differences between ethnic groups seen were anatomic distribution of cancer in the colon (statistically significant) and male-to-female ratio of colon cancer (apparent but not statistically significant). Characteristics are classified into three types: (1) Not influenced by ethnicity or by environment: Dukes' stage at presentation, colon-to-rectum ratio, histology, length of hospital stay, survival; (2) Possibly influenced by environment. mean age, male-to-female ratio, presence of synchronous polyps, duration of symptoms; (3) Influenced by ethnicity: anatomic distribution of cancer in the colon.
为了研究除发病率和死亡率之外的该疾病特征，对一家服务于多民族城市人口的社区医院的所有（311例）新结直肠癌病例进行了为期10年的回顾性研究。尽管在大多数特征上存在种族差异，但仍有显著相似性。各民族之间唯一可见的差异是结肠癌在结肠的解剖分布（具有统计学意义）和结肠癌的男女比例（明显但无统计学意义）。特征分为三种类型：（1）不受种族或环境影响：就诊时的杜克分期、结肠与直肠比例、组织学、住院时间、生存率；（2）可能受环境影响：平均年龄、男女比例、同步息肉的存在、症状持续时间；（3）受种族影响：结肠癌在结肠的解剖分布。
