Chemotherapy + Hormone Therapy With Surgery for Prostate Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests whether combining chemotherapy (using docetaxel) and hormone therapy (using drugs like leuprolide or goserelin) before surgery is more effective than surgery alone for treating high-risk localized prostate cancer. The goal is to determine if this combination can shrink the tumor, making surgery easier and potentially more successful. This trial suits those diagnosed with high-risk prostate cancer who have not undergone previous treatments like surgery or radiation and are candidates for prostate surgery. Participants must have a specific cancer profile, including a Gleason score of 8 or higher, with no signs of cancer spread. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to potentially groundbreaking treatment advancements.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications. However, you should not have had prior treatment for prostate cancer, except for up to 4 months of certain hormone therapies. It's best to discuss your current medications with the trial team.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
In a previous study, 103 patients received docetaxel, and 34% required hospitalization due to side effects. The study also reported 17 cases of febrile neutropenia, characterized by fever and low white blood cell counts. However, another study found that different dosing schedules of docetaxel were generally well-tolerated by men with advanced prostate cancer.
Research has shown that goserelin, a hormone therapy, is generally safe and effective. It significantly reduces testosterone levels, aiding in prostate cancer treatment. Common side effects include hot flashes and cancer-related pain.
For leuprolide, another hormone therapy, studies indicate it is generally safe. While it may cause some heart-related effects, the overall risk appears manageable.
In summary, while these treatments carry some risks, many patients tolerate them well. Consulting a doctor is crucial to understand how these findings apply to individual health needs.12345Why are researchers excited about this trial's treatments?
Researchers are excited about combining chemotherapy, hormone therapy, and surgery for prostate cancer because it offers a more comprehensive approach than traditional treatments, which often focus on just one or two strategies. Typically, standard care involves either surgery or hormone therapy alone. By integrating docetaxel, a chemotherapy drug, with LHRH agonists for hormone therapy, and following up with surgery, this method aims to attack cancer on multiple fronts. This multi-pronged strategy could potentially improve outcomes by shrinking tumors before surgery, making them easier to remove, and reducing the risk of cancer returning. Additionally, the option for adjuvant radiation therapy post-surgery adds another layer of treatment to further target any remaining cancer cells.
What evidence suggests that this trial's treatments could be effective for prostate cancer?
In this trial, participants in Arm A will receive a combination of the drug docetaxel with hormone therapy (such as leuprolide or goserelin) before undergoing surgery. Research has shown that this combination effectively treats prostate cancer. Studies have found that adding docetaxel to standard hormone treatments can lead to better patient outcomes. Hormone therapy stops the body from making testosterone, which can help prostate cancer grow. Docetaxel prevents cancer cells from multiplying, potentially shrinking tumors. This combination has proven beneficial in other hormone-responsive prostate cancer cases. Overall, this approach appears promising for reducing prostate tumor size before surgery. Participants in Arm B will undergo surgery without preceding chemotherapy and hormone therapy.678910

Are You a Good Fit for This Trial?
This trial is for men with high-risk localized prostate cancer who are fit for surgery and expected to live more than 10 years. They must have a specific type of prostate cancer (adenocarcinoma), no prior treatments except possibly short-term hormone therapy, and no evidence of spread beyond the prostate. Men with other recent cancers or certain blood clotting events not suitable for surgery can't join.Inclusion Criteria

Trial Overview
The study is testing if giving chemotherapy drug docetaxel along with hormone therapies leuprolide or goserelin before surgery offers better outcomes compared to just having the surgery alone. The goal is to see if this combination treatment can shrink tumors more effectively, making them easier to remove surgically.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
All patients undergo standard surgical intervention. The surgical procedures will be performed within 60 days of randomization. Patients are allowed to receive adjuvant external beam radiation at the discretion of the treating physician and as defined per the protocol. Adjuvant radiation must be initiated within 6 months of the date of surgery.
Patients receive six cycles of docetaxel administered every 3 weeks combined with 18-24 weeks of androgen deprivation therapy. During each cycle of chemotherapy, all patients should undergo premedication with dexamethasone 8 mg orally prior to docetaxel. Dexamethasone may also be given intravenously according to institutional guidelines. Patients will also receive androgen deprivation for 18-24 weeks of an LHRH agonist (eg, leuprolide acetate, goserelin acetate). Additional premedication and antiemetics may be given at the physician's discretion and as defined by the protocol. Patients will undergo standard surgical intervention. The surgical procedures will be performed within 60 days of the completion of neoadjuvant therapy. Patients are allowed to receive adjuvant external beam radiation at the discretion of the treating physician and as defined per the protocol. It must be initiated within 6 months of the date of surgery.
