Docetaxel, Androgen Ablation, and External-Beam Radiation Therapy in Patients With High-Risk Localized Prostate Cancer

• Status: Completed
• Trial end date: 2012-08-01
• Target enrollment: 0
• Participant gender: Male

Summary

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.

Criteria

Inclusion Criteria:

1. 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

2. No evidence of metastatic disease on chest x-ray, bone scan or CT scan of abdomen/pelvis.

3. Age > 18

4. The Eastern Cooperative Oncology Group (ECOG) Performance Status 0-1

5. Peripheral neuropathy: must be < grade 1

6. Hematologic parameters A) Absolute neutrophil count > 1,500/mm3 B) Hemoglobin > 8.0 g/dL C) Platelet count > 100,000/mm3.

7. 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)

8. 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.

9. Patient must be willing to consent to using effective contraception while on treatment and for at least 3 months thereafter.

Exclusion Criteria:

1. Documented metastases on staging studies

2. Life expectancy <10 years secondary to co-morbid illness

3. 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)

4. Patients with a history of severe hypersensitivity reaction to docetaxel or other drugs formulated with polysorbate 80

5. History of invasive malignancy within the last five years prior to study entry except for carcinoma in situ or nonmelanoma skin cancer.

6. Psychiatric conditions which would prevent compliance with treatment or adequate informed consent.

7. Patients receiving another investigational agent during chemo- and radiotherapy

8. Uncontrolled intercurrent illness or other conditions that limit compliance with protocol treatment
