BackgroundThis study analyzed the immunoexpression of calcitonin receptor (CTR) and glucocorticoid receptor (GR) in central giant cell lesions (CGCLs) and verified potential associations with patient's response to clinical treatment with intralesional injection of triamcinolone. Materials and methodsFifty-four cases of CGCLs, including 22 non-aggressive, and 32 aggressive, were investigated by immunohistochemistry. ResultsSurgery was the therapeutic choice for 53.1% of the aggressive CGCLs, and 46.9% were submitted to the conservative treatment with intralesional triamcinolone injections. Among patients submitted to conservative treatment, 60% (n=9) showed favorable response. CTR expression was observed in 68.51%, and GR in 94.44% of the total sample. There were no differences in the expression of CTR, neither GR in mononucleated stromal cells (MSCs) or multinucleated giant cells (MGCs), in relation to aggressiveness, treatment performed for and the response to conservative treatment. Both markers showed a positive correlation between their expression in MSCs and MGCs in the total sample (P<0.0001). CTR expression on MSCs showed a positive correlation with MGCs in the aggressive and non-aggressive groups (P<0.0001). ConclusionsCalcitonin receptor and GR expression were diffuse and similar in non-aggressive and aggressive cases, and it did not influence the response to clinical treatment with triamcinolone in the sample studied.
