由于日本结直肠癌发病率的显著增加，为了确定结直肠癌在部位分布、年龄和性别方面的特征，我们调查了1975年至1994年间1205名日本结直肠癌患者。当我们比较整个20年间年龄和性别的部位分布时，老年患者结肠近端肿瘤发生率高于年轻患者（p < 0.05）；这一趋势仅在女性中存在（p < 0.01），而在男性中不存在。老年患者中近端结肠癌的发病率在第二个10年期间也有所增加（p < 0.05）。由于近年来老年患者近端结肠癌的发病率越来越高，因此需要更多的共同努力来早期发现近端结肠癌，特别是在老年人中。
To define the characteristics of colorectal cancer with regard to site distribution, age, and sex, due to the significantly increased incidence of colorectal cancer in Japan, we investigated 1,205 Japanese patients with colorectal cancer between 1975 and 1994. When we compared site distribution for age and sex in the entire 20-year period, tumors in the proximal colon were more frequent in elderly patients than in young ones (p < 0.05); this tendency was true only for females (p < 0.01), but not for males. The increased incidence of proximal mal colon cancer in elderly patients was also found in the second 10-year period (p < 0.05). Because elderly patients are characterized by an increasingly high incidence of proximal colon cancer in recent years, more concerted efforts for the early detection of proximal colon cancer, particularly in the elderly, are called for.
