Trial Outcomes & Findings for Docetaxel, Radiation Therapy, and Prednisone in Treating Patients Who Have Undergone Surgery For Prostate Cancer (NCT NCT00348816)

NCT ID: NCT00348816

Last Updated: 2017-12-08

Results Overview

Subjects were followed after the intervention and monitored for PSA (Prostate Specific Antigen) decline for up to 5 years of follow-up, to determine how many had a decline and reached a PSA nadir of zero..

Participant Flow

Enrollment opened on 21 Mar 2006 and closed on 15 Apr 2009. The first subject was consented on 18 May 2007 and the final subject on 14 Apr 2009. Subjects were all enrolled in outpatient clinics and received treatment as outpatients.

Subjects must have histologic diagnosis of prostate cancer and be post prostatectomy. They must have a PSA \> 0.2 ng/ml (verified on 2 separate tests, at least 2 weeks apart). CT abdomen/pelvis and bone scan must be negative. One subject was a screen failure due to CT showed lung mass (not related to prostate cancer).

Measure
Docetaxel (Single Arm)
Docetaxel 20mg/m2/week IV every week during radiation treatment (7 cycles). Post radiation: docetaxel 75mg/m2 IV every 21 days for 4 cycles plus prednisone 5mg PO BID QD. Adjuvant therapy: radical prostatectomy as part of standard care Radiation therapy: Doses for standard care radiation therapy: The initial target volume will be the lower pelvis followed by a boost to the prostate fossa and immediate periprostatic tissue. The initial dose will be 4500 cGy. With the final boost, the total dose will be 6840-6900 cGy. (4500/25 plus 2340/13 or 2400/12) with a total of 37 or 38 fractions.

PRIMARY outcome

Timeframe: 5 years

Population: Exceptions to group description: (1) one subject non-compliant and taken off study (not included in analysis); (2) one subject did not receive docetaxel #7 during radiation due to change in performance status; (3) one subject received only 1 post radiation docetaxel; (4) two subjects did not receive post radiation docetaxel #4.

Subjects were followed after the intervention and monitored for PSA (Prostate Specific Antigen) decline for up to 5 years of follow-up, to determine how many had a decline and reached a PSA nadir of zero..
