Clinical benefit of patients with advanced adrenocortical carcinoma (Acc) treated in phase I clinical trials: the royal marsden hospital (Rmh) experience

Custodio Ana , Lopez Juanita , de Bono Johann S

Introduction: After progression on conventional treatment options, some patients with advanced ACC are offered experimental Phase I therapies. The outcomes of these patients have not yet been formally evaluated. This study aims to describe the experience of refractory ACC patients treated on Phase I clinical trials at the RMH.Methods: We retrospectively reviewed the records of metastatic ACC patients consecutively treated in our Drug Development Unit bet...

Androgens initially drive prostate tumour growth. Although in advanced disease there is no longer dependence on circulating androgens, the androgen receptor (AR) remains a key driver of this lethal stage thus new ways to inhibit its activity are required. MicroRNAs play vital roles in prostate cancer (PCa) development, progression and metastasis. Previous studies have examined microRNAs dysregulated in PCa, and also identified androgen-regulated microRNAs. We approached microR...

With the wide-spread use of abiraterone/enzalutamide for CRPC, there is an urgent need to understand and reverse resistance to these treatments. Studies have implicated glucocorticoid receptor (GR) as activating androgen receptor (AR) signalling and driving resistance. Here we studied progesterone receptor (PR), which is phylogenetically most closely related to the AR. We first used digital droplet PCR in prostate cancer (PCa) cell lines and observed >10 times higher level...

MiR-346 is an Androgen Receptor (AR)-activating miR that associates with DNA damage response (DDR)-linked transcripts in prostate cancer (PC). MiR-346 induces rapid and extensive DNA damage in PC cells through chromatin association, activation of transcription, R-loop formation and DNA replication stress, leading to checkpoint activation and cell cycle arrest. MiR-346 interacts with lncRNA, NORAD, in PC cells, which functions to maintain mitosis, DDR, and chromosomal integrity...
