Patient case: 81-year-old male with Prostate cancer. Genetic variant: PTEN Inactivating. Other conditions: Hypertension, Depression.

Clinical trial: Care of the Prostate Cancer Patient and Prospective Procurement of Prostate Cancer Tissue

Summary: Background:
  Prostate cancer is the most common noncutaneous cancer among men in the U.S. Researchers want to study blood, tissue, and fluid samples of people with prostate cancer. This will help them understand any changes in cells and genes. These changes might lead to the development and progression of prostate cancer. Researchers think the study could lead to new treatments.
  Objective:
  To understand the changes in cells and genes that lead to the development and progression of prostate cancer. This could lead to new treatments.
  Eligibility:
  Men ages 18 and older who have or are suspected to have prostate cancer
  Design:
  Participants will be screened with physical exam and medical history.
  Participants will send tissue blocks of their tumor, if possible. If not, they will provide unstained slides of tumor tissue.
  Participants may provide samples of blood, urine, saliva, and prostate secretions.
  Participants may have imaging tests. They will lie in a machine that takes pictures of their body. These tests include:
  MRI of the prostate
  CT of the abdomen and pelvis
  Chest x-ray
  Participants may need a biopsy or surgery for treatment of their cancer. If so, researchers will collect tissue.
  Participants may answer questions about their prostate cancer and quality of life.
  Participants may have follow-up visits or other treatments. They may have follow-up phone calls every few months.

Detailed description: Background:
  -  Prostate carcinoma is the second most common malignancy diagnosed in men. Approximately 1 in 6 men will be diagnosed with prostate cancer in their lifetime.
  -  Understanding the molecular mechanisms and genomic alterations that cause prostate carcinoma will provide the foundation for the development of novel targeted therapeutic agents for this disease. Since 1982 investigators in the Urologic Oncology Branch have been studying the genetic basis of urologic cancers. The identification of the genes for cancer of the kidney has led to the approval by the FDA of a number of new agents for patients with advanced disease. Similarly, it is our goal to study the cancer biology (genomic, molecular, and cellular biology) of prostate carcinoma in order to develop novel treatment strategies.
  -  Collection of patient tumor samples allows us to study molecular and biologic pathways and develop novel targeted therapies. Correlation of these samples with radiographical findings and clinical outcomes in patients allows us to predict and understand clinical outcomes and possibly develop predictive and/or prognostic biomarkers.
  Objectives:
  Primary: Collect blood, urine, saliva, expressed prostatic secretions, and benign and malignant tissue from patients with known or suspected prostate cancer for the purpose of elucidating the molecular mechanisms of carcinogenesis in prostate cancer and ultimately, identifying novel therapeutic targets.
  Eligibility:
  - Adults with biopsy-proven or suspected prostate cancer who require diagnostic or therapeutic intervention as part of their diagnosis, standard of care treatment, or followup/ surveillance for their neoplasm.
  Design:
  -  Tissue acquisition protocol in which normal and malignant prostate cancer tissues may be obtained at the time of clinically indicated diagnostic and/or therapeutic intervention.
  -  Blood and urine samples for research will be obtained at baseline and follow-up intervals. Expressed prostatic secretions may be collected at baseline and follow-up intervals. Additionally, saliva may be collected at baseline.
  -  No investigational or experimental therapy will be given as part of this protocol.

Eligibility: -  INCLUSION CRITERIA:
  -  Adults (greater than or equal to 18 years of age) with biopsy-proven or suspected prostate cancer (elevated PSA or abnormal digital rectal exam (DRE)) who require and are willing to undergo diagnostic or therapeutic intervention as part of their diagnosis, standard of care treatment, or follow-up/surveillance for their neoplasm.
  -  ECOG performance status of 0-2
  -  Must be willing and able to provide informed consent
  EXCLUSION CRITERIA:
  -Subjects whose comorbidities would preclude diagnostic or therapeutic intervention.
