结直肠黏液腺癌淋巴结转移度的临床病理意义

目的探讨结直肠黏液腺癌淋巴结转移度的临床病理意义。方法收集2011年1月—2013年12月该院收治的26例结直肠黏液腺癌患者临床病理资料,根据性别、年龄及肿瘤部位进行分组,病理诊断确定各组术后标本收获淋巴结数及有肿瘤转移的阳性淋巴结数,按照淋巴结转移度=（阳性淋巴结数/收获淋巴结数）×100%,计算淋巴结转移度并进行统计学比较。结果 26例结直肠黏液腺癌中,男性患者淋巴结转移度（37.29%）明显高于女性（14.29%）;65岁以上患者淋巴结转移度（40.63%）明显高于65岁以下（19.29%）;左半结肠和直肠肿瘤患者淋巴结转移度（46.59%）明显高于右半结肠（21.11%）,差异有统计学意义（P〈0.001）。结论结直肠黏液腺癌淋巴结转移度与患者性别、年龄及肿瘤部位有关。

Clinicopathological Significance of Lymph Node Metastasis Ratio in Colorectal Mucinous Adenocarcinoma

Objective To investigate the clinicopathological significance of lymph node metastasis ratio in colorectal mucinous adenocarcinoma.Methods The clinicopathological data of 26 cases with colorectal mucinous adenocarcinoma admitted in our hospital from January 2011 to December 2013 were collected.And the patients were divided into different groups according to the sex,age and tumor location.The number of invaded lymph nodes and the total number of resected lymph nodes in surgical specimens were diagnosed by pathologists.The lymph node metastasis ratio,which is the ratio between the number of invaded lymph nodes and the total number of resected lymph nodes,were analyzed statistically.Results Of the 26 cases with colorectal mucinous adenocarcinoma,the lymph node metastasis ratio in males（37.29%） was significantly higher than that in females（14.29%）;and that in 65 years or older（40.63%） was obviously higher than that in under age 65（19.29%）;that in left hemicolon and rectal cancer（46.59%） was much higher than that in right hemicolon（21.11%）,the differences were statistically significant（ P〈0.001）.Conclusion The lymph node metastasis ratio of colorectal mucinous adenocarcinoma is correlated with the sex,age and tumor location of patient.
