同时性结直肠癌肝转移的临床病理特征分析

目的遴选同时性结直肠癌肝转移的危险因素，为预测和早期诊断肝转移提供参考依据。方法收集2003年1月至2006年12月间收治的367例原发性结直肠癌患者的临床病理资料，对患者的年龄、性别、血型、肿瘤家族史、是否合并肝炎肝硬化、有无合并肠梗阻、术前癌胚抗原（CEA）和CA19－9、原发肿瘤部位和大小、分化程度、肿瘤侵及深度、有无淋巴结转移、肿瘤分期等19项因素进行统计分析。结果本组发生同时性结直肠癌肝转移56例．占同期结直肠癌患者的15．3％。在发病年龄、是否有肠梗阻、是否有盆腔转移结节及肿瘤浸润深度方面，肝转移和无肝转移两组患者之间差异有统计学意义（P〈0．05）。右侧结肠癌肝右叶转移瘤者明显多于左叶，而左侧结肠癌转移瘤多分布于全叶。当术前CEA大于22．1μg／L时，患者发生肝转移的可能性增加。结论结直肠癌同时性肝转移与患者年龄、是否存在肠梗阻、盆腔有无转移及CEA水平存在密切关系。

Clinicopathological analysis of synchronous hepatic metastases from colorectal cancer]

OBJECTIVE: To screen the clinicopathological factors of synchronous hepatic metastases from colorectal cancer for early diagnosis and therapy. METHODS: Clinicopathological data of 367 cases with colorectal cancer from Jan. 2003 to Dec. 2006 in our department were collected to set up the database. All the patients were divided into two groups according to hepatic metastases or not. Clinicopathological factors were analyzed, such as age, sex, blood type, tumor family history, hepatitis and cirrhosis history, peritoneal or pelvic metastases, bowel obstruction, CEA, CA19-9, tumor localization and size, histological type, infiltration depth, lymph node metastases etc. RESULTS: Out of 367 colorectal cancer cases, there were 56 cases with synchronous hepatic metastases from colorectal cancer, accounting for 15.3%. The age, bowel obstruction, peritoneal or pelvic metastases, and tumor invasion depth were associated with the hepatic metastases. The primary tumor located in the right colon resulted in more right lobe hepatic metastases than those in the left lobe. The serum CEA level was associated with hepatic metastases. When serum CEA was more than 22.1 microg/L, the occurrence rate of hepatic metastases increased. CONCLUSION: Peritoneal or pelvic metastases, bowel obstruction, age and serum CEA level are associated with synchronous hepatic metastases from colorectal cancer.
