Proton Radiation Therapy in Treating Patients With Prostate Cancer

2014-08-27 03:16:47 | BioPortfolio

Summary

RATIONALE: Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue.

PURPOSE: This clinical trial is studying how well proton radiation therapy works in treating patients with prostate cancer.

Description

Detailed Description

PRIMARY OBJECTIVES:

I. Feasibility of proton radiation therapy (RT) using standard fractionation.

SECONDARY OBJECTIVES:

I. To determine freedom from failure (FFF) (vs. biochemical/clinical progression-free survival) with standard fractionation.

II. To determine the incidence of grade 2 or greater GU and GI toxicity with this regimen at 6 months, 2 years and 3 years.

III. To assess quality of life issues following completion of radiation therapy at 6 months and at 2 years.

IV. To assess incidence of impotence after the use of proton therapy at 3 years.

V. To determine freedom from biochemical failure (BF) at 5 years.

VI. To determine clinical failure: local and/or distant at 5 years. VII. To determine salvage androgen deprivation (SAD) use at 5 years. VIII. To determine progression free survival: using clinical, biochemical and SAD as events at 5 years.

IX. To determine overall survival at 5 years. X. To determine disease-specific survival at 5 years.

XI. Estimate prostate and normal structures movement during RT with the use of scans.

XII. Correlate pathologic and radiologic findings with outcomes at 5 years. XIII. Correlate PSA and free PSA levels with outcomes at 5 years. XIV. Correlate testosterone levels and variation with proton therapy and outcomes at 5 years.

XV. Develop a quality assurance process for proton prostate therapy.

OUTLINE:

Patients undergo proton radiotherapy once daily 5 days a week for approximately 9 weeks in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed at 3 months, every 6 months for 5 years, and then annually thereafter.

Medical and Biotech [MESH] Definitions

The use of an external beam of PROTONS as radiotherapy.

An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.

Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.

A measurement index derived from a modification of standard life-table procedures and designed to take account of the quality as well as the duration of survival. This index can be used in assessing the outcome of health care procedures or services. (BIOETHICS Thesaurus, 1994)

Activities and programs intended to assure or improve the quality of care in either a defined medical setting or a program. The concept includes the assessment or evaluation of the quality of care; identification of problems or shortcomings in the delivery of care; designing activities to overcome these deficiencies; and follow-up monitoring to ensure effectiveness of corrective steps.
