BackgroundThe management of post-operative recurrences of ACC remains controversial, although the current guidelines recommend a surgical approach whenever feasible with radical intent.AimThe aim of our study was to evaluate retrospectively the management of recurrences in patients with ACC. We collected data of 106 patients with ACC followed at the San Luigi Hospital for the management of recurrence. Median ...

Background and objectives: The role of adjuvant mitotane therapy after radical surgery for adrenocortical carcinoma (ACC) is still debated. The aim of our study is to assess the effects of adjuvant mitotane on recurrence free survival (RFS) and overall survival (OS) in non-metastatic ACC patients and to evaluate prognostic factors in adjuvant setting.Methods: Retrospective data were collected from 152 patients affected by ACC (stage I-III) referred to ou...

Background: More than 50% of adrenocortical carcinomas (ACC) in adults are associated with cortisol excess that makes tumor management challenging and has a negative impact on patient outcome. Abiraterone acetate (AA) is an irreversible inhibitor of the 17α-hydroxylase/C17, 20-lyase (CYP17 enzyme) that is used in patients with prostate cancer, in whom it leads to suppression of cortisol and androgens. The aim of this study was to assess the activity of AA to control corti...

Background and objective: Mitotane is the main option of treatment for advanced adrenocortical carcinoma (ACC). However, limited evidence is available regarding practical management of mitotane treatment and its eventual combination with chemotherapy or radiotherapy. The aim of the study is to do a survey on the use of mitotane for advanced ACC in expert Italian centers, analyzing data of the LYSOSAFE database.Methods: Retrospective analysis of patients ...

Background: The management of adjuvant mitotane therapy in patients with adrenocortical carcinoma (ACC) is challenging. Plasma mitotane concentrations>14 mg/l have been associated with efficacy in the treatment of advanced ACC; however, data in the adjuvant setting are mixed. Moreover, there is no consensus on how to assess the optimal exposure to mitotane and all the proposed methods have inherent limitations. We have recently proposed a new method analogous to what is es...

Background and objective: Mitotane is widely used as post-operative adjuvant treatment of adrenocortical carcinoma. However, the management of therapy is largely empirical. Mitotane monitoring is recommended but we do not know what impact target concentrations do have on patient outcome. The aim of the study is to evaluate its use in expert Italian centers, analyzing data of Lysosafe Online® database.Methods: Retrospective analysis of patients repor...

Background: Adrenocortical carcinoma (ACC) has an aggressive but heterogenous behaviour. ENSAT stage and Ki67 proliferation index are used to predict clinical outcome but are limited in distinguishing patients with best outcome. We aimed to validate the prognostic role of clinical and histopathological parameters alone or combined by applying a previously proposed points-based score (mGRAS, Lippert JCEM 2018) to a large multicentre cohort of ACC patients.<p class="abstext"...

BackgroundThe ESE-ENSAT guidelines suggest adjuvant mitotane for patients with adrenocortical carcinoma (ACC) at high risk of recurrence following radical surgery. This indication has a limited evidence base, lacking results from randomized controlled trials. No suggestion is available in low-risk patients, since studies did not stratify patients for prognosis. The randomized controlled study ADIUVO compared the efficacy of adjuvant mitotane (MIT) treatm...
