NCT ID: NCT00214136
Last Updated: 2021-08-04
Results Overview

Participant Flow
This study enrolled patients with high-risk prostate adenocarcinoma or radiographic evidence of pelvic lymph node involvement but absence of distal metastases from the Midwest. The last patient completed in February 2016.
All participants are assigned to the experimental arm.

Gastrointestinal disorders
Acute GI Grade 1

52.0%
13/25 • Participants were followed up 1 month upon completion, every 3 months for 1 year after treatment, every 4 months during Years 2 and 3, every 6 months during Years 4 and 5, and then annually, with median follow up time as 25.4 months (range, 4.2 - 57.2 months). Bone scans and CT during follow-ups were not routinely performed but were carried out in the context of rising PSA levels. Of 30 participants, only 25 met the minimum follow up thresholds at the time of analysis.
Toxicity grading is based on a modified RTOG acute/late toxicity grading criteria. Serious adverse events are defined as all Grade 4 and Grade 5 toxicities. Acute toxicities are scored from the start of radiation to 90 days after completion of radiation. Late toxicities are scored \> 90 days from the completion of radiation therapy for 5 years.
