1975年～1990年作者共收治589例大肠癌,30岁以下31例,70岁以上50例。将两组资料进行比较发现:两组均以腹痛及便血为主(58%～61%)。但青年人就诊前病程(6个月)明显长于老年人(2个月)。直肠是青老年人大肠癌的好发部位(42%～48%),青年纽就诊时多为进展期且粘液癌多于老年组。Dukes 分期青年组 C、D 期最多,老年组 B 居多。青年大肠癌5年生存率为40.3%,较老年组55.3%(P<0.05)差。
From 1975 to 1990, the authors treated a total of 589 cases of colorectal cancer, 31 cases under the age of 30, and 50 cases over the age of 70. Comparing the two sets of data found that: The two groups were mainly abdominal pain and blood in the stool (58% to 61%). However, the course of disease before the young people (6 months) was significantly longer than that of the elderly (2 months). The rectum is the predilection site of colorectal cancer in young adults (42% to 48%), and most of the young people in the New York visit are advanced and have more mucinous cancer than the elderly group. The Dukes stage youth group has the most stages C and D, and the elderly group B mostly. The 5-year survival rate of young colorectal cancer was 40.3%, which was worse than that of the older group (55.3%, P<0.05).
