The site distribution of 853 histologically verified colorectal adenocarcinomas diagnosed at a Norwegian regional hospital from 1964 through 1978 was studied retrospectively. There was a notable increase in the annual number of diagnosed tumours from the first to the last 5-year period of the study. No significant change in site distribution could be found. Men had a higher proportion of rectal cancer than women (43% versus 31%) and a lower proportion of tumours of the right and transverse colon (29% versus 38%). Significant differences in site distributions between men and women, however, were found only in the age group above 60 years. Of the colorectal tumours in the present series 20% were within the reach of the examining finger on rectal examination.
对1964年至1978年在挪威一家地区医院确诊的853例经组织学证实的结肠直肠癌的部位分布进行了回顾性研究。在研究的第一个到最后一个5年期间，每年确诊肿瘤的数量有显著增加。未发现部位分布有显著变化。男性直肠癌的比例高于女性（43%对31%），右半结肠和横结肠癌的比例低于女性（29%对38%）。然而，仅在60岁以上年龄组中发现男性和女性在部位分布上有显著差异。在本系列的结肠直肠肿瘤中，20%在直肠指检时手可触及范围内。
