Brief Summary

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 uses radioactive material placed directly into or near a tumor to kill tumor cells. Giving luteinizing hormone-releasing hormone agonist together with an iodine I 125 implant may be an effective treatment for patients with prostate cancer. PURPOSE: This randomized phase III trial is studying how well giving luteinizing hormone-releasing hormone agonist therapy together with an iodine I 125 implant works with or without additional luteinizing hormone-releasing hormone agonist therapy in treating patients with previously untreated prostate cancer.

Study Arms (2)

AHT group

ACTIVE COMPARATOR

Randomized patients undergo 3-month neoadjuvant therapy (NHT)within 14 days and receive 9-month adjuvant therapy (AHT) following after Iodine I-125 implantation (TPPB).

Drug: Adjuvant therapyDrug: Neoadjuvant therapyRadiation: Brachytherapy(iodine I 125)

Non-AHT group

ACTIVE COMPARATOR

Rondomized patients undergo 3-month neoadjuvant therapy (NHT) within 14 days and receive Iodine I-125 implantation therapy (TPPB). 40 weeks observation is followed under no further treatment.

Drug: Neoadjuvant therapyRadiation: Brachytherapy(iodine I 125)

Interventions

AHT group receives 9 cycle of LHRH-A (goserelin acetate 3.6 mg/4 weeks or leuprorelin acetate 3.75 mg/4 weeks) after Iodine I-125 implantation (TPPB).

AHT group

3 cycle of LHRH-A (goserelin acetate 3.6mg/4 weeks or leuprorelin acetate 3.75mg/4 weeks).
