As regards hormonal receptors co-expression, our current findings that only 26.4% showed positivity while the rest were negative compare well with those reported from Sudan and Nigeria but not with a previous Tanzanian study on the clinical and epidemiological profiles of 57 breast cancer patients which found that 41% had ER/PR co-expression [22, 41, 46]. The gene discussed is NR4A1; the disease is breast cancer.
