RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Giving radiation therapy through seeds implanted into the prostate may kill more tumor cells.
OBJECTIVES: I. Evaluate the effectiveness of transrectal ultrasound guided permanent radioactive implantation of the prostate in patients with confined adenocarcinoma of the prostate. II. Assess the overall survival, disease specific survival, clinical relapse (local or distant), PSA levels, and genitourinary and gastrointestinal morbidity in these implant patients. III. Assess the quality of life of these patients.
OUTLINE: This is a multicenter study. Patients receive transrectal ultrasound guided radioactive I-125 seeds implanted into the prostate. At least one week prior to implant, patients undergo transurethral ultrasound study to determine the volume of prostate. Following implantation, seeds that have extruded into the bladder or lodged in the urethral wall are retrieved, and extra seeds may be implanted into identified "cold spots" for uniform seed distribution. Prostate rebiopsy is required before starting hormonal therapy for local progression or biochemical failure without clear focus of progression. Quality of life is assessed every 3 months for 1 year, then every 6 months for 1 year, and then annually for 3 years. Patients are followed every 3 months for 1 year, then every 6 months for 2 years, and then annually thereafter.
PROJECTED ACCRUAL: A total of 95 patients will be accrued for this study within 1 year.

RATIONALE: Radioactive drugs, such as radioactive iodine, may carry radiation directly to tumor cells and not harm normal cells. Placing a gene called Ad5CMV-NIS in prostate cancer cells m...
The size of the prostate changes due to insertion of the radioactive seeds. We will measure the prostate size, before and after the procedure.
RATIONALE: Androgens can cause the growth of prostate cancer cells. Luteinizing hormone-releasing hormone agonists may lessen the amount of androgens made by the body. Internal radiation u...
Retrospective study to analyze Quality of life in men after iodine seed brachytherapy for localized prostate cancer
The purpose of this study is to find out if the drug AZD6244 can improve the radioactive iodine uptake by the patient's metastatic thyroid cancer. The investigator will also be testing the...
Investigating oncological outcomes in patients registered in the Japanese Prostate Cancer Outcome Study of Permanent Iodine-125 Seed Implantation (J-POPS) in terms of biochemical relapse-free survival...
Prostate Cancer is the forth most common type of cancer. Prostate-specific membrane antigen (PSMA) is anchored in the cell membrane of prostate epithelial cells. PSMA is highly expressed on prostate e...
The only prognostic factor of prostate-specific antigen (PSA) bounce in prostate cancer found in several studies is young age but has never been specifically studied in this subset of patients for lon...
To examine whether age-related reference ranges for "normal" prostate-specific antigen (PSA) change (determined in men without prostate cancer) can be used to identify men at high risk of having prost...
The role of testosterone in the development of prostate cancer and the safety of testosterone therapy (TTh) after prostate cancer treatment, or in the setting of active surveillance, remains controver...
A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.
Stable iodine atoms that have the same atomic number as the element iodine, but differ in atomic weight. I-127 is the only naturally occurring stable iodine isotope.
A synthetic retinoid that is used orally as a chemopreventive against prostate cancer and in women at risk of developing contralateral breast cancer. It is also effective as an antineoplastic agent.
Tissue ablation of the PROSTATE performed by ultrasound from a transducer placed in the RECTUM. The procedure is used to treat prostate cancer (PROSTATIC NEOPLASMS) and benign prostatic hypertrophy (PROSTATIC HYPERPLASIA).
Proteins secreted by the prostate gland. The major secretory proteins from the human prostate gland include PROSTATE-SPECIFIC ANTIGEN, prostate-specific acid phosphatase, prostate-specific membrane antigen, and prostate-specific protein-94.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
