本文分析近5年来食管癌136例,胃癌353例和大肠癌223例的发病年龄。食管癌和大肠癌的平均年龄男女无显著差别,而胃癌则女性比男性年轻(P<0.05)。食管癌、胃癌和大肠癌的平均年龄分别为50.59±9.63岁、51.86±10.23岁和45.86±13.02岁。上消化道癌明显年长于下消化道癌(P<0.01)。 人肠癌的平均年龄右侧为51.54±13.79岁,与胃癌相近,明显地高于左侧大肠癌(45.66±12.61岁)或直肠癌(44.69±12.51岁)(P<0.01)。高分化癌的平均年龄47.95±12.44岁,明显大于粘液腺癌的38.59±11.67岁(P<0.01)和低分化腺癌的40.05±14.40岁(P<0.05)。
This article analyzes the age of onset of 136 cases of esophageal cancer, 353 cases of gastric cancer and 223 cases of colorectal cancer in the past 5 years. The average age of esophageal cancer and colorectal cancer was not significantly different between men and women, while gastric cancer was younger than men (P<0.05). The average ages of esophageal cancer, gastric cancer, and colorectal cancer were 50.59±9.63 years, 51.86±10.23 years, and 45.86±13.02 years, respectively. The upper gastrointestinal cancer was significantly longer than the lower gastrointestinal cancer (P<0.01). The average age of human colon cancer was 51.54±13.79 years on the right, which was similar to that of gastric cancer, which was significantly higher than that of left colorectal cancer (45.66±12.61 years) or rectal cancer (44.69±12.51 years) (P<0.01). The average age of well-differentiated carcinoma was 47.95±12.44 years, which was significantly higher than that of mucinous adenocarcinoma (38.59±11.67) (P<0.01) and poorly differentiated adenocarcinoma (40.05±14.40) (P<0.05).
