The treatment landscape of metastatic castration-resistant prostate cancer (mCRPC) has dramatically improved over the last decade; however, patients with visceral metastases are still faced poor outcomes. Phosphatase and tensin homolog ( PTEN ) loss is observed in 40%–60% mCRPC also associated a prognosis. Several PI3K/AKT/mTOR pathway inhibitors have been studied, disappointing anti-tumor acti...
Objective. To compare the effects of different treatment strategies for metastatic hormone-sensitive prostate cancer (mHSPC) using a network meta-analysis. Methods. English databases (PubMed, Embase, and medRxiv) Chinese (Wanfang CNKI) were searched randomized controlled trials (RCTs) on mHSPC from inception to June 1, 2021. The overall survival (OS) failure-free (FFS) reported by included stud...
BACKGROUND Few prognostic models for overall survival (OS) are available for patients with metastatic castration-resistant prostate cancer (mCRPC) treated with recently approved agents. We developed a prognostic index model using readily available clinical and laboratory factors from a phase III trial of abiraterone acetate (hereafter abiraterone) in combination with prednisone in post-docetaxe...
PURPOSE Abiraterone may suppress androgens that stimulate breast cancer growth. We conducted a biomarker analysis of circulating tumor cells (CTCs), formalin-fixed paraffin-embedded tissues (FFPETs), and serum samples from postmenopausal estrogen receptor (ER)+ breast cancer patients to identify subgroups with differential abiraterone sensitivity. METHODS Patients (randomized 1:1:1) were trea...
Tumor mechanisms of abiraterone resistance in clinical prostate cancer are not well defined. Chen and colleagues report that a T878A androgen receptor mutation occurs in a subset of patients progressing while receiving abiraterone, suggesting that this may be a therapeutically exploitable mechanism of abiraterone resistance in castration-resistant prostate cancer.
Background Abiraterone and cabazitaxel improve survival in patients with metastatic castration-resistant prostate cancer (mCRPC). We conducted an open-label phase I/II trial of cabazitaxel plus abiraterone to assess the antitumor activity and tolerability in patients with progressive mCRPC after docetaxel (phase I), and after docetaxel and abiraterone (phase II) (NCT01511536). Patients and me...
BACKGROUND Androgen receptor (AR) signaling and incomplete inhibition of estrogen signaling may contribute to metastatic breast cancer (MBC) resistance to a nonsteroidal aromatase inhibitor (NSAI; letrozole or anastrozole). We assessed whether combined inhibition of androgen biosynthesis with abiraterone acetate plus prednisone and estradiol synthesis with exemestane (E) may be of clinical bene...
The objective of this study was to investigate whether the prior use of a novel androgen receptor-axis-targeted (ARAT) agent with or without subsequent taxane therapy could affect the efficacy of another ARAT agent in patients with metastatic castration-resistant prostate cancer (mCRPC). This study included a total of 302 patients with mCRPC, who were treated with abiraterone acetate and/or enz...
PURPOSE ErbB2 signaling appears to be increased and may enhance androgen receptor (AR) activity in a subset of patients with castration-resistant prostate cancer (CRPC), but agents targeting ErbB2 have not been effective. This study was undertaken to assess ErbB2 activity in abiraterone-resistant prostate cancer and to determine whether it may contribute to AR signaling in these tumors. EXPER...
BACKGROUND There are no validated clinical decision tools to aid optimal treatment selection in men with metastatic castration-resistant prostate cancer (mCRPC). Frequently, abiraterone and enzalutamide are used prior to chemotherapy in mCRPC, given the more favorable safety profiles. However, there is no published data on clinical outcomes regarding best sequencing of these two agents. METHO...
