Abstract:
Objective Through detect the expression of DLC1 and RhoA protein in breast cancer tissues ,investigate the effect of DLC1 and RhoA in lymphatic metastasis of breast cancer .Methods Totally 25 breast cancer specimens that had occurred lymph node metastasis and 30 breast cancer specimens that had not occurred lymph node metastasis were collected ,the expression of DLC1 and RhoA were tested by immunochemistry ,and the experimental data were analyzed by statistical methods .Results The positive rate of DLC1 in the breast cancer specimens that had occurred lymph node metastasis was 44 .00% ,that had not occurred lymph node metastasis was 73 .33% (χ2 =4 .889 ,P=0 .027) ,and the positive rates of RhoA in the two specimens were 92 .00%and 50 .00% (χ2 =11 .264 ,P=0 .001) .Spearman rank correlation analysis showed the expression of DLC 1 and RhoA had a nega‐tive correlation in breast cancer tissues (r= -0 .454 ,P=0 .000) .Conclusion The breast cancer lymphatic metastasis and is closely related to the low expression of DLC1 and the high expression of RhoA .
