Neoadjuvant Therapy of Abiraterone Plus ADT for Intraductal Carcinoma of the Prostate

February 3, 2021 updated by: Hao Zeng, West China Hospital

A Single-center, Phase II Neoadjuvant Study of Abiraterone Acetate in the Treatment of Intraductal Carcinoma of the Prostate

Neoadjuvant treatment before radical prostatectomy has been proven to provide benefits on peri-operation results, especially on reduction of tumor volume and minimization of biochemical recurrence. This study will evaluate the efficacy and safety of abiraterone acetate Plus androgen deprivation therapy（ADT）in high-risk localized prostate cancer with intraductal carcinoma of the prostate（IDC-P）.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

IDC-P is an adverse pathological entity of prostate cancer, characterized by the growth of malignant cells in pre-existing prostatic ducts and acini, and is present in high-grade disease and associated with poor prognosis. Previous studies have shown that IDC-P was significantly associated with an adverse clinical course in patients who received radical prostatectomy or radiotherapy, and the presence of IDC-P on the biopsy specimen was associated with a poor prognosis in terms of overall survival (OS) and a poor docetaxel response in patients with distant metastasis at the initial diagnosis. Our previous researches as well as other published data indicated that abiraterone had a better therapeutic efficacy than docetaxel as the first-line therapy in metastatic castration resistance prostate cancer（mCRPC）with IDC-P. Therefore we intended to perform this single-arm phase II clinical trial to evaluate the initial efficacy and safety of abiraterone acetate Plus ADT as neoadjuvant therapy for high-risk localized prostate cancer with IDC-P. The primary endpoint is the pathologic complete response (pCR).
