Outcome Measures

Primary Outcomes (1)

  • Immunohistochemistry of tumor cell proteins will be performed on prostate biopsies to detect for androgen receptors and other protein products related to oncogenes or tumor suppressor genes thought to play a role in radiation or ADT.

    2 years follow up

Secondary Outcomes (2)

  • DNA sequencing will be performed on prostate tumor DNA to determine the mutational status of several oncogenes and tumor suppressor genes including genes coding androgen receptors.

    2 years follow up

  • RNA sequencing will be performed on several oncogenes and tumor suppressor genes including genes coding androgen receptors to detect RNA expression including genes related to the androgen receptor.

    2 years follow up

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The inclusion (target study population) criteria for this retrospective outcomes analysis are adult patients (older than 18 years at time of treatment) with high risk prostate cancer who were treated with proton therapy at UFHPTI/Department of Radiation Oncology. For this retrospective outcomes study, data will be used from patients treated between 6/10/2010 through 4/26/17 with at least 2 years follow up.

You may qualify if:

  • Adult patients (older than 18 years at time of treatment) with high risk prostate cancer who were treated with proton therapy at UFHPTI/Department of Radiation Oncology
  • Patients treated between 6/10/2010 through 4/26/17 with at least 2 years follow up
