Wang L、Hollenbeak CS及Stewart DB通过分析1992~2006年以来接受根治性切除的结肠癌患者的流行病学和最终结果监测(SEER)登记数据,对<40岁的患者(n=2 642)和≥40岁的患者(n=138 769)进行对比。结果发现获取的淋巴结平均数和平均受累数量在年轻患者中更高。年轻患者肿瘤更可能发生转移,其受累淋巴结数量12枚,且患淋巴结阴性结肠癌的几 Wang L, Hollenbeak CS, and Stewart DB analyzed data from the Epidemiology and End Results Monitoring (SEER) registry of colon cancer patients who underwent radical resection from 1992 to 2006 and analyzed data from patients <40 years of age (n = 2 642) and Patients ≥40 years of age (n = 138 769) were compared. The results showed that the average number of lymph nodes acquired and the average number affected in younger patients was higher. Tumors in young patients are more likely to metastasis, the number of involved lymph nodes 12, and the number of patients with lymph node-negative colon cancer
