Introduction: Adrenocortical carcinoma (ACC) is a rare disease with a poor prognosis and limited therapeutic options. Mitotane is considered as a first-line therapy but only 30% of the patients showing an objective tumour response.Erlotinib and gefitinib (tyrosine kinase inhibitors – TKI) inhibit the epidermal growth factor receptor (EGFR), which is highly expressed and occasionally mutated in various cancers. EGFR expression was found to be a good ...

Introduction: Adrenocortical carcinoma (ACC) has a poor prognosis and limited therapeutic options. The epidermal growth factor receptor (EGFR) expression was found to be a good discriminator between malignant and benign adrenal tumours, but was mutated only in 3–10% of ACC cases.Aim: The aim of this study was to assess the effect of inhibition of EGFR with targeted therapies, i.e. Erlotinib (with and without EGF stimulation) on ACC cell proliferatio...
