ABSTRACT
Objective To investigate the relation between expression of JARID1B/KDM5B in invasive breast cancer tissue and circulating tumor cells of invasive breast patients. Methods The S-P immunohistochemical method was used to observe the expression of JARID1B/KDM5B in lesions.imFISH method was used to detect circulation tumor cells. Results Twenty-seven cases of patients showed CTC positive(the number of CTC was more than or equal to 2) in 35 invasive breast cancer cases,The results of JARID1B/KDM5B expression were as follows:(-) (n=0) and (+) in 1 case,(++) in 3 cases,(+++) in 23 cases,8 cases of negative cases (the number of CTC < 2), JARID1B/KDM5B immune group of results:(-) (n=2),(+) in 2 cases,(++) in 1 case,(+++) in 3 cases, The positive relation was found in expression of JARID1B/KDM5B and circulating tumor cells(P<0.05). Conclu-sions JARID1B/KDM5B positive expression in tumor tissues has a certain significance in predicting the recurrence and metastasis of tumor.
