目的 探讨不同年龄组结肠癌患者的特点。方法 按年龄分为青年组 (≤ 35岁 ) ,中年组 (36～5 9)岁 ,老年组 (≥ 6 0岁 )。比较不同年龄组结肠癌患者在临床表现、镜下表现、病理及雌激素受体表达等肿瘤特征资料。结果 青年组腹痛占 72 2 % ;中老年组粘血便为主 ,占 86 5 %。青年组右半结肠癌多于老年组。老年男性雌激素受体 (ER)阳性率显著降低。结论 本组结肠癌患病高峰为 6 0～ 70岁。青年组右半结肠癌发生率高 ,恶性程度高 ,转移早 ,进展快。中老年组左半结肠多见 ,病程长 ,分化好
Objective To investigate the characteristics of colon cancer patients of different age groups. The methods were divided into young group (≤ 35 years), middle aged group (36-59 years) and elderly group (≥ 60 years) by age. The clinical features, microscopic features, histopathology and estrogen receptor expression in colorectal cancer patients of different age groups were compared. Results The young group had 72 2% of abdominal pain, while the middle-aged and elderly patients had the majority of sticking blood, accounting for 86.5%. Right colon cancer group than the elderly group. The positive rate of estrogen receptor (ER) in elderly men was significantly lower. Conclusion The highest incidence of colon cancer in this group is 60 ~ 70 years old. The right group of young colon cancer high incidence, high degree of malignancy, early metastasis, rapid progress. More common in the left half of the elderly group, long course, good differentiation
