About this study

Official title: Dosimetric and Morbidity Outcomes of Cs-131 Brachytherapy in Combination With External Beam Radiation Therapy in Subjects With Intermediate to High Risk Adenocarcinoma of the Prostate: An Observational Study

The purpose of this study is to observe PSA response and incidence of side effects in patients diagnosed with intermediate to high risk prostate cancer and treated with Cesium-131 in combination of external beam therapy.

Conditions
Prostate Cancer
Keywords
prostate, cancer, intermediate risk, high risk, brachytherapy, Cesium-131, seed brachytherapy, intermediate and high risk cancer of the prostate

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The analysis of dosimetric data resultant from Cs-131 permanent prostate brachytherapy in combination with external beam radiation therapy in the setting of intermediate to high risk cancer of the prostate.

    Data collected for analysis will be total therapeutic dose delivered to the prostate by the Cs-131 brachytherapy implant treatment in units of Gy.

    Measured: 5 years

Secondary outcomes (2)
  1. The analysis of treatment related morbidities following Cs-131 prostate brachytherapy in combination with external beam therapy for intermediate to high risk cancer of the prostate.

    Data collected for analysis will be the EPIC prostate cancer quality of life questionnaire.

    Measured: 5 years

  2. The analysis of PSA control rates following Cs-131 prostate brachytherapy in combination with external beam therapy for intermediate to high risk cancer of the prostate.

    Data collected for analysis will be PSA measurements.

    Measured: 5 years
