CyberKnife Dose Escalation Prostate Cancer Trial
Prostate CancerProstate Adenocarcinoma1 moreStereotactic body radiation therapy (SBRT) has been employed in the treatment of prostate cancer. Multiple single institution experiences suggest high biochemical control rates with acceptable toxicity in low risk prostate cancer but efficacy data in unfavorable type prostate cancer is less convincing. CyberKnife-SBRT (CK-SBRT) can be used to escalate radiation dose delivery to the prostate while sparing normal tissue.
Trial to Investigate the Benefit of Elective Para-Aortic Radiotherapy (PART) for pN1 Prostate Cancer...
Prostate CancerProspective non-randomized phase 2 trial to study the efficacy of additional elective para-aortic RT (PART) in pN1 patients compared to those who were historically treated with adjuvant whole pelvic radiotherapy (WPRT) alone.
Androgen Deprivation Therapy (ADT) Versus ADT Plus Prostate Cryotherapy for Metastatic Prostate...
Prostate Cancer MetastaticPatients with primary diagnosed metastatic prostate cancer are randomly divided into two groups. One group receive standard of care ADT continually. Another group receive ADT plus prostate cryotherapy. Patients are followed up until their death or withdraw from this study due to other reasons. The primary endpoint of this study is prostate cancer Progression-Free Survival. The secondary endpoint is overall survival, prostate cancer specific survival and health-related quality of life.
A Study for Subjects With Prostate Cancer Who Previously Participated in an Enzalutamide Clinical...
Prostate CancerThe purpose of this study is to collect long term safety data in subjects who are continuing to derive clinical benefit from treatment with Enzalutamide from the subjects participation in an enzalutamide clinical study sponsored by Astellas or Medivation (i.e., parent study) which has completed, at a minimum, the primary analysis or the study specified evaluation period.
Evaluation of Response to Abiraterone/Prednisone by Race/Ethnicity and Other Factors in Metastatic...
Prostate Cancer MetastaticProstate CancerThe investigators are conducting this study with men that have prostate cancer and are getting standard of care treatment with the drugs abiraterone acetate and prednisone. The study will follow men with prostate cancer from initiation of participation in the study and for up to 10 years. The reason for the study is that researchers think that there may be a connection between the race and ethnicity of men with prostate cancer and how well the standard treatments work for the participants.

Sequencing of Radium-223 and Docetaxel in Symptomatic Bone-only Metastatic Castration-resistant...
Metastatic Castration-resistant Prostate CancerRandomized, multicentre phase II trial of the sequencing of Radium-223 and Docetaxel plus prednisone in symptomatic bone-only metastatic castration-resistant prostate cancer (mCRPC) Open-label, randomized phase II trial in patients with symptomatic bone-only metastatic castration-resistant prostate cancer. Eligible patients are randomly assigned into two arms: Arm A: radium-223 initially followed by docetaxel plus prednisone at the time of progression (the second step is optional according to clinical evolution of disease) Arm B: docetaxel plus prednisone initially followed by radium-223 at the time of progression (the second step is optional according to clinical evolution of disease).

Cystoprostatectomy Versus Radiotherapy Combined With ADT for the Treatment of cT4 Prostate Cancer...
Prostate CancerProstate cancer is the most common male cancer in global, which accounts for 19% of the total and poses great hazards to male health. Unfavorable factors including prostatic specific antigen (PSA) >20 ng/ml, Gleason score >8, and T3/4 are significantly associated with biological recurrence, metastatic progression and poor survival in prostate cancer. In clinical T4(cT4) prostate cancer with bladder invasion patients, symptoms of hematuria, urinary urgency, bladder outlet and ureteral obstruction, and pelvic pain led to a poor quality of life. Radical prostatectomy is crucial for the multimodal treatment of prostate cancer, but limited proof demonstrated enough advantages of the surgery in T4 tumor with bladder invasion. Radical prostatectomy could hardly meet both demands of local tumor control and urinary function. Treatment trends suggest that patients with T4 prostate cancer be treated with radiotherapy combined with androgen deprivation therapy (ADT). However, surgery enables a full pathological assessment of the tumor characteristics and thus a better estimation of the risk of recurrence. Cystoprostatectomy offers an option of surgical treatment for T4 prostate cancer with bladder invasion,which can well remove the bladder and urethra, decrease the risk of positive surgical margins and avoid urination complications. There is no consensus regarding optimal treatment of T4 prostate cancer and no evidence of oncological outcomes of cystoprostatectomy from clinical trials. A randomized clinical trial comparing two multimodal treatment regimens of cystoprostatectomy and radiotherapy for T4 prostate cancer with bladder invasion is therefore warranted.
