Abstract

Sex steroids play an important part in the functioning of normal gallbladder, formation of gallstones and possibly in the pathogenesis of gallbladder cancer. Steroids receptors have been previously demonstrated on normal and malignant gall bladder tissues. To study this phenomenon further, we correlated clinicopathological features and survival with estrogen receptor (ER) status of the tumour in 30 patients with histologically- proven adenocarcinoma of the gallbladder. Estrogen receptor assay was performed immuno-histochemically utilizing Universal Immunoperoxidase Staining Kit. Tumor tissue was obtained either surgically or with fine needle aspiration of the gallbladder mass. There were 27 females and 3 males. Eighteen patients had estrogen receptors expressed on the malignant tissue, 12 were negative. Comparison of clinicopathological characteristics and survival between the two groups demonstrated no significant difference in gender, mean age, marital status and parity. Similarly, presence of gallstones, histologic grade or survival did not correlate with the estrogen receptor status. There is, however, a trend in favour of poorly differentiated tumors being more often receptor negative. Further studies are necessary to elucidate the biologic significance of these receptors.
