目的

探讨影响中低位直肠癌侧方淋巴结阳性的危险因素。

方法

回顾性分析2019年1月1日至2020年12月30日两家医院102例中低位直肠癌行腹腔镜根治性切除并进行侧方淋巴结清扫术患者的临床资料,根据侧方淋巴结转移情况将其分为阳性组(n=21例)和阴性组(n=81例)。临床数据采用SPSS 22.0软件进行统计学分析,计数资料以[n(%)]表示,采用χ2Fisher精确检验;侧方淋巴结阳性的危险因素采用Logistic多因素分析。以P<0.05为差异有统计学意义。

结果

102例中低位直肠癌患者侧方淋巴结清扫总数为1347枚,其中阳性淋巴结占比为8.1%;单因素分析结果显示,患者年龄、肿瘤直径、分化程度、肿瘤类型、T分期及浸润肠壁程度与侧方淋巴结阳性的发生均有明显相关性(P<0.05);Logistic回归分析显示,低分化、浸润型、T3-4期及浸润肠壁浆膜外肿瘤是中低位直肠癌侧方淋巴结阳性的独立危险因素(P<0.05)。

结论

中低位直肠癌患者肿瘤组织低分化、浸润型癌、肿瘤分期T3-4及浸润肠壁浆膜外可作为判断侧方淋巴结转移的独立危险因素,建议对存在这些危险因素的患者行侧方淋巴结清扫术。

Objective

To investigate the risk factors of lateral lymph node positivity in middle and low rectal cancer.

Methods

The data of 102 patients with middle and low rectal cancer who underwent laparoscopic radical resection and lateral lymph node dissection from January 1,2019 to December 30,2020 were retrospectively analyzed,and they were divided into positive group(n=21cases)and negative group(n=81cases)according to the lateral lymph node metastasis. The clinical data were statistically analyzed by SPSS 22.0 software,and the count data were expressed as[n(%)],using χ2 or Fisher's exact test. Logistic multifactor analysis was used for risk factors of positive lateral lymph nodes,and P<0.05 was considered as statistically significant difference.

Results

A total of 1347 lateral lymph nodes were dissected in 102 patients with low and middle rectal cancer,and 8.1% of them were positive lymph nodes. Univariate analysis showed that age,tumor diameter,degree of differentiation,tumor type,T stage and degree of intestinal wall invasion were significantly correlated with the occurrence of lateral lymph nodes(P<0.05). Logistic regression analysis showed that the degree of low differentiation,invasive type,T3-4 stage and extrapserous tumor infiltrating intestinal wall were independent risk factors for positive lateral lymph nodes in low and middle rectal cancer(P<0.05).

Conclusion

Low differentiation of tumor tissue,invasive cancer,tumor stage T3-4 and infiltration of intestinal wall beyond serous membrane in patients with low and medium rectal cancer can be used as independent risk factors for lateral lymph node metastasis,and lateral lymph node dissection is recommended for patients with these risk factors.
