简要总结
RATIONALE: Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as leuprolide, may lessen the amount of androgens made by the body. Radiation therapy uses high energy x-rays to kill tumor cells. Giving docetaxel together with androgen ablation therapy and external-beam radiation therapy may kill more tumor cells.
PURPOSE: This phase I/II trial is studying the side effects and best dose of docetaxel when given together with androgen ablation therapy and external-beam radiation therapy and to see how well they work in treating patients with high-risk localized prostate cancer.
详细描述
OBJECTIVES:
Primary
- Determine the dose-limiting toxicity and maximum tolerated dose of docetaxel when administered in combination with androgen ablation therapy and adaptive external-beam radiotherapy in patients with high-risk localized adenocarcinoma of the prostate.
Secondary
- Determine the 2-year biochemical progression-free survival of patients treated with this regimen.

入选标准
- •Histologically confirmed adenocarcinoma of the prostate with any of following clinical features:
- •A) T3 or T4 B) T1-2 + Gleason Score 8-10 C) T1-2 + Gleason Score 7 + Prostate Specific Antigen (PSA) >10 ng/mL D) T1-2 + Any Gleason Score + PSA >20 ng/mL
- •No evidence of metastatic disease on chest x-ray, bone scan or CT scan of abdomen/pelvis.
- •The Eastern Cooperative Oncology Group (ECOG) Performance Status 0-1
- •Peripheral neuropathy: must be < grade 1
- •Hematologic parameters A) Absolute neutrophil count > 1,500/mm3 B) Hemoglobin > 8.0 g/dL C) Platelet count > 100,000/mm
- •Hepatic parameters / Renal function A) Total Bilirubin must be ≤ 1.2 mg/dL B) Transaminases (AST and ALT) must be < 1.5 x upper limit of normal (ULN) C) Alkaline phosphatase must be < 2.5 x ULN D) Creatinine < 1.5 x ULN ( < 2.1 mg/dL)
- •No prior pelvic or prostate radiation or chemotherapy for prostate cancer. Androgen ablation therapy with one of the luteinizing hormone-releasing hormone (LH-RH) agonists prior to enrollment is acceptable as long as protocol treatment with radiotherapy and chemotherapy is started within 3 months of the initiation of androgen ablation.
- •Patient must be willing to consent to using effective contraception while on treatment and for at least 3 months thereafter.
排除标准
- •Documented metastases on staging studies
- •Life expectancy <10 years secondary to co-morbid illness
- •Myocardial infarction or significant change in anginal pattern within one year prior to study entry or current congestive heart failure (New York Heart Association Class 2 or higher)
- •Patients with a history of severe hypersensitivity reaction to docetaxel or other drugs formulated with polysorbate 80
- •History of invasive malignancy within the last five years prior to study entry except for carcinoma in situ or nonmelanoma skin cancer.
- •Psychiatric conditions which would prevent compliance with treatment or adequate informed consent.
- •Patients receiving another investigational agent during chemo- and radiotherapy
- •Uncontrolled intercurrent illness or other conditions that limit compliance with protocol treatment
研究组 & 干预措施
Single Arm Intervention
Single Arm Intervention where after enrollment (or prior to enrollment but before starting radiotherapy) patients will initially receive leuprolide acetate (Lupron®) intramuscular (IM). Patients will begin adaptive external-beam radiation therapy 2-3 months following the initiation of hormonal therapy. Each patient receives a dose of docetaxel at 10 mg/m2 intravenously over 1 hour weekly for eight weeks, for a total of eight weeks.
干预措施: docetaxel (Drug)
