The concept of metaplastic and non-metaplastic types of gall bladder cancer and the likelihood of hormone receptor expression in the nuclei of tumour cells raised the possibility of a potential role for anti-estrogen therapy in gall bladder cancer. This study was carried out to determine the hormone receptors (ER/PR) expression level in gall bladder cancer using specific immunohistochemical assays and correlate it with patient and tumour histopathological characteristics.
