Spots Global Cancer Trial Database for Dose-Escalated Proton Radiation Therapy for High-Risk Prostate Cancer

Study Description

Brief Summary: The purpose of this research study is to determine if dose-escalated proton radiation therapy is a good way to treat high-risk prostate cancer. The study features hypofractionation and a simultaneous integrated boost to the magnetic resonance imaging (MRI) identified intraprostatic tumor (IPT) as a method of dose-escalating radiation therapy. The study will include patients with high-risk prostate cancer who are at the highest risk for recurrence. Radiation therapy will be delivered over the course of 8-9 weeks. Additionally, androgen deprivation therapy (ADT) will be started 8-10 weeks prior to starting radiation and continued for a total of 18 months if the patient decides to receive ADT.

Detailed Description: Prostate cancer is the most common noncutaneous cancer among men in the United States. The purpose of this research study is to determine if dose-escalated proton radiation therapy is a good way to treat high-risk prostate cancer. Proton therapy (PT) is a type of ionizing radiation therapy that reduces the dose of excess radiation delivered to normal tissues. By escalating the radiation dose just to the area of the known tumor within the prostate, one could potentially reduce the amount of excess radiation delivered to surrounding organs.This reduction in dose would improve the therapeutic ratio by improving disease control while minimizing the risk for additional toxicity. In an effort to take advantage of dose escalation's potential for improving disease control but also to limit toxicity, the use of advanced imaging to identify prostate cancer and provide a focal radiation boost to the area have proven to be useful. Recent advances in MRI have made it the most promising technique in identifying and targeting IPTs, improving both cancer control rates and decreasing toxicity.

The study will include patients with high-risk prostate cancer who are at the highest risk for recurrence. Radiation therapy will be delivered over the course of 8-9 weeks. Additionally, androgen deprivation therapy (ADT) will be started 8-10 weeks prior to starting radiation and continued for a total of 18 months.
