RATIONALE: Radiation therapy uses high-energy x-rays and other sources to damage tumor cells. Giving radiation therapy in different ways may kill more tumor cells.
OBJECTIVES: I. Determine the acute and late grade 3-5 genitourinary and gastrointestinal toxic effects of external beam radiotherapy followed by permanent source brachytherapy using interstitial iodine I 125 seeds in patients with intermediate risk, clinically localized adenocarcinoma of the prostate. II. Determine the freedom from PSA failure, overall survival, disease specific survival, and local and/or distant clinical relapse rates in patients treated with this regimen.
OUTLINE: This is a multicenter study. Patients undergo external beam radiotherapy (EBRT) to the pelvis 5 days a week for 5 weeks. Permanent source brachytherapy comprised of ultrasound-guided implantation of iodine I 125 seeds into the prostate is performed 2-6 weeks after completion of EBRT. Patients are followed at 1, 3, 6, 9, and 12 months, then every 6 months for 2 years, and then annually thereafter.
PROJECTED ACCRUAL: A total of 110 patients will be accrued for this study within 1 year.
Primary Purpose: Treatment

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...
RATIONALE: Androgens can stimulate the growth of prostate cancer cells. Drugs such as goserelin, leuprolide, flutamide, or bicalutamide may stop the adrenal glands from producing androgens...
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...
RATIONALE: Hormones can stimulate the growth of prostate cancer cells. Hormone therapy may fight prostate cancer by reducing the production of androgens. Radiation therapy uses high-energy...
RATIONALE: Implant radiation therapy uses radioactive material placed directly into or near a tumor to kill tumor cells. PURPOSE: This phase II trial is studying the side effects and how ...
We analyzed factors associated with rectal toxicity after iodine-125 prostate brachytherapy (BT) with or without external beam radiation therapy (EBRT).
To evaluate the cancer control outcomes and long-term treatment-related morbidity of brachytherapy as well as combination brachytherapy and EBRT in patients with intermediate-risk prostate cancer.
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 aim of this study was to compare early prostate-specific antigen (PSA) decline patterns and PSA nadirs between low-dose-rate seed prostate brachytherapy (LDR-PB) and different fractionations of ex...
Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.
Unstable isotopes of iodine that decay or disintegrate emitting radiation. I atoms with atomic weights 117-139, except I 127, are radioactive iodine isotopes.
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.
Drug therapy given to augment or stimulate some other form of treatment such as surgery or radiation therapy. Adjuvant chemotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
Organs which might be damaged during exposure to a toxin or to some form of therapy. It most frequently refers to healthy organs located in the radiation field during radiation therapy.
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...
