The relationship between lymph node metastasis and some clinicopathologic variables in mucinous and non mucinous colorectal adenocarcinoma

Background and objective: Involvement of lymph nodes is an important prognostic factor in most cancers, including colorectal cancer in which lymph node status is the strongest pathologic predictor of patient outcome. This study aimed to find any relationship between lymph node metastasis and associated clinicopathologic variables in colorectal carcinoma. Methods: In this retrospective study, 136 cases of colorectal cancer were reviewed from Rizgary Teaching Hospital and some private labs in Erbil, Kurdistan region, Iraq during the period between August 2010 and December 2015. All cases were surgically treated with total colectomy or hemi colectomy. Results: A total of 136 cases of colorectal cancer were included in this study; 53% presented with one or more lymph node metastasis, 47% were between 40 and 60 years of age and 68% were male. There was no statistically significant relationship between lymph node status and any of the studied clinicopathologic variables. Conclusion: In colorectal adenocarcinoma, there was no statistically significant correlation between lymph node involvement and any of the studied clinicopathologic variables including tumor size, anatomic location, differentiation and histologic type, depth of invasion or patient gender and age
