The relationship between the expressions of tumor associated fibroblasts Cav-1 and MCT4 and the prognosis of papillary carcinoma of breast

The aim of this study was to evaluate the expression levels of cav-1 and mct4 in the tumor stroma cafs. immunohistochemical method was used to detect the expression of cav-1 and mct4 in 86 cases of impc,with 105 cases of non-specific invasive ductal carcinoma (idc-nos) as control. their differential expression in different histological types were compared and relationship between the expression of cav-1 and impc in the mct4 and the main pathological features such as age,tumor size and histological grades were analyzed. the study confirmed that the loss expression of cav-1 on cafs and the up-regulation of mct4 may be the possible mechanisms of cafs in tumorigenesis,which may be one of the molecular mechanisms leading to the poor prognosis of impc. the expression of cafs related proteins in tumor microenvironment suggested that cafs could be used as the target of tumor therapy and provide new evidence for the treatment of breast cancer.
