Abstract

Objective: To study the estrogen receptor (ER), progesterone receptor (PR) and Her-2 Receptor status in breast cancer patients.


Methods: Retrospective descriptive study. A total of 437 patients with breast cancer treated in Radiation Oncology Division, Faculty of Medicine Vajira hospital between 1996-2009 were enrolled. Clinical and histological data were assessed from medical records and pathological reports. The results were reported as the expression of Estrogen, Progesterone and Her-2 Receptors status and the factors affecting the expression of all receptors were analyzed.


Results: The ER, PR and HER2 were positive in 56.10%, 53.24% and 33.52%, respectively. The proportion of ER+PR+, ER+PR-, ER-PR+, ER-PR- were 46.98 %, 9.56%, 5.46% and 37.2%. Her-2 showed highest positive frequency (17.82%) when both ER and PR were negative. Her-2 showed highest negative frequency (41.37%) when both ER and PR were positive. ER and PR overexpression were associated significantly with lower histological grade (p=0.04 and 0.01). Her-2 overexpression was significantly associated with higher histological grade (p<0.001)


Conclusion: ER and PR positive is the most common status. We found the relationship between the expression of ER, PR and Her-2 receptor status. ER, PR and Her-2 overexpression were associated with histological grade.
