Background
Nipple areola complex (NAC) infiltration in operable breast carcinoma (OBC) is associated with local recurrence. NAC infiltration in OBC suggests that RAC1, RHOA and CXCR4 proteins are risk factors for migration and infiltration of OBC to NAC. This study aims to analyze the expression and interactions of these proteins as risk factors for NAC infiltration in OBC.
Materials and methods
This is an analytic observational cross-sectional study coupled with a categorical comparative study in each 40 subjects of OBC with and without NAC infiltration. The immunohistochemistry performed with a cut-off point based on the result of a receiver operating characteristics (ROC).
Results
RAC1, p < 0.001 with POR 5.76, 95% CI: 2.06–16.08; RHOA, p < 0.001 with POR 7.00, 95% CI: 2.28–21.53; and CXCR4, p = 0.001 with POR 6.33, 95% CI 2.06–19.49. There was an interaction between RAC1 and RHOA (p < 0.001 with POR 17.14, 95% CI: 3.07-125.66); between RAC1 and CXCR4 (p < 0.001 with POR 30.93, 95% CI 3.62–686.89); between RHOA and CXCR4 (p < 0.001 with POR 10.21, 95% CI 2.19–54.17); and between the RAC1, RHOA and CXCR4 proteins (p < 0.001 with POR = 23.69, 95% CI 2.51–544.86).
Conclusion
We conclude that the expression of the RAC1, RHOA, and CXCR4 proteins and their interactions play a role as risk factors of NAC infiltration.
