The absence of early malignant changes in women subjected to Aquafilling breast augmentation on the basis of E-cadherin and N-cadherin immunohistochemical expression

The use of Aquafilling can be associated with a variety of health complications. The filler is an inflammatory process trigger at the site of tissue contact. The aim of this study was to semiquantitatively compare the immunohistochemical expression of E-cadherin and N-cadherin in tissue material from two groups of patients. The first group underwent surgical removal of Aquafilling from the breast, while the second was subjected to breast augmentation with implants or breast lifts (control group). The study group consisted of tissue samples from 16 patients who had Aquafilling removed, while the control group comprised samples from 16 patients who underwent breast augmentation with implants or breast lifts. Histopathology, immunohistochemistry and morphometric analyses were performed, taking into account the number of immunopositive cells and also the immunohistochemical reaction area for E-cadherin and N-cadherin. There were significantly more immunopositive N-cadherin cells in both groups. The immunohistochemical reaction area for N-cadherin did not differ between the two groups. However, the immunohistochemical reaction area for E-cadherin was significantly larger in the test group than in the control group. Moreover, the reaction area for N-cadherin was significantly smaller than that for E-cadherin. In the control group, no significant differences were detected between the immunohistochemical reaction area for N-cadherin and E-cadherin. Immunohistochemical evaluation of N-cadherin and E-cadherin tissue expression may be useful in assessing early cell junction changes. Furthermore, semiquantitative morphometric analysis allows these alterations to be more precisely determined.
