RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Amifostine may protect normal cells from the side effects of radiation therapy.
OBJECTIVES: I. Determine the incidence, grade, and time course of acute grade 2 or higher gastrointestinal and genitourinary toxicities in patients with primary prostate adenocarcinoma receiving amifostine plus fractionated radiotherapy. II. Determine the incidence and nature of toxicity associated with amifostine in these patients. III. Assess tumor response to this treatment in these patients. IV. Assess impotency rates following radiotherapy in these patients.
OUTLINE: This is an open label study. Patients receive fractionated radiotherapy five days per week for 7 weeks plus amifostine IV push over 5 minutes, 15 minutes before each radiation treatment. Patients are followed at 1 month after radiotherapy, and then every 3 months for at least 5 years.
PROJECTED ACCRUAL: There will be 25 patients accrued into this study over 2 years.
Primary Purpose: Treatment
amifostine trihydrate, radiation therapy

RATIONALE: Drugs used in chemotherapy, such as cisplatin, use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to dam...
RATIONALE: Amifostine may be an effective treatment for the toxic side effects caused by radiation therapy and chemotherapy. It is not yet known whether chemotherapy and radiation therapy ...

We describe a 75-year-old man with undifferentiated prostate cancer that was treated with radiation therapy. He presented at a nearby general hospital with dysuria and pain upon micturition. He was di...
Changes in sexual function other than erectile dysfunction are sparsely investigated after radiation therapy for prostate cancer.
To evaluate the safety, feasibility, side-effect profile, and proof of concept of external beam radiation therapy (EBRT) with or without a brachytherapy (BT) boost for salvage of exclusive local failu...
It is unknown whether there is a benefit to starting androgen deprivation therapy (ADT) prior to rather than concurrently with definitive radiation therapy in men with high-risk prostate cancer. We st...
Background Salvage radiation therapy is often necessary in men who have undergone radical prostatectomy and have evidence of prostate-cancer recurrence signaled by a persistently or recurrently elevat...
Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.
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.
A phosphorothioate proposed as a radiation-protective agent. It causes splenic vasodilation and may block autonomic ganglia.
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...
