    Abstract:
    A retrospective review was performed on 576 patients who have been diagnosed breast cancer and referred to Division of Radiation Therapy, Department of Radiology, King Chulalongkorn Memorial Hospital between January 1995-September 2001. There were three hundred ninety nine cases of invasive breast cancer that available for estrogen (ER) and/or progesterone (PR) receptor status. The mean and median age in our study were 49.6 year and 49.0 year respectively. About 60.9 per cent of the patients were pre and peri-menopause and 37.8 per cent were post-menopause. Most of the histological cell type were invasive ductal carcinoma which comprised of 92.7 per cent. Histologic grading were nearly equal for moderately and poorly differentiated grade: 43.66 per cent and 40.66 per cent. The results of our study showed 53.4 per cent of 399 patients had ER positive and 42.1 per cent of 380 patients had PR positive. The proportion of ER+PR+, ER+PR-, ER-PR+, and ER-PR- were 36.31 per cent, 15.53 per cent, 5.79 per cent and 42.37 per cent respectively. Older age and post-menopause women had higher ER+. While patients with increase tumor size, poorly differentiated grading, increase positivity of axillary lymph nodes and higher stage have more chance of ER negative and PR negative.
