Abstract:
Objective To investigate the correlation between serum antinuclear antibody (ANA) expression and clinicopathologic characteristics as well as the prognosis in colorectal cancer patients.Methods Analysis was performed for 198 cases with histologically proven adenocarcinoma of colorectal cancer who underwent curative resection from January 2009 to December 2010.There were 113 males and 85 females,average age of 63.9 (22 to 92) years.Serum ANA expression was detected by indirect immunofluorescence.Chi-square test was used to analyze the relationship between clinicopathological features and serum ANA expression,Kaplan-Meier analyses were used to compare DFS between ANA positive and negative group,multivariate analysis was used to measure the impact of confounding variables on survival.Results Positive serum ANA was detected in 51 (25.76％) of the 198 patients,higher than that of the control group 8％ (4/50).By univariate analysis,we found that serum ANA positive was related to age ＜ 65 years (x2 =4.87,P =0.027 3),tumor size ≥5 cm (x2 =5.56,P =0.018 3),invasion depth (x2 =325.89,P ＜0.000 1) and tumor course≥5 months (x2 =5.43,P =0.019 8) respectively,and not related to gender,tumor location,tumor differentiation,lymph node and distant metastasis (P ＞ 0.05).Multivariate analysis identified that only invasion depth of tumor led to serum ANA expression significantly.Conclusions Tumor invasion depth impacts on serum ANA expression significantly,while the expression has no correlation with the prognosis of colorectal cancer.
