Prostate Cancer Treatment: Options for Medication, Surgery & More

Understanding Prostate Cancer: A Comprehensive Overview

Prostate cancer is a common diagnosis for men, and navigating the landscape of potential treatments can feel overwhelming. Even as some treatments are considered standard practice, a growing number of options are becoming available through clinical trials, offering the potential to refine and improve existing approaches. The best course of action is always determined by a careful consideration of the cancer’s stage and characteristics, the individual’s overall health, and a thorough discussion of potential side effects with a healthcare team.

How is Prostate Cancer Treated?

Treatment strategies for prostate cancer are diverse, encompassing medication, surgery, and radiation therapy. Increasingly, personalized approaches are being explored, including targeted therapies and immunotherapies, designed to harness the body’s own defenses against the disease. For some men, a strategy of watchful waiting or active surveillance may be appropriate, particularly in cases of slow-growing cancer or when the potential benefits of immediate treatment are outweighed by the risks.

Medication Options: Targeting the Cancer at a Cellular Level

A range of medications are used to manage prostate cancer, each working through a different mechanism. These include hormone therapy, chemotherapy, targeted therapy, and immunotherapy.

Hormone Therapy: Depriving Cancer of Fuel

Hormone therapy, also known as androgen deprivation therapy (ADT), aims to reduce or block the effects of male hormones, called androgens, which fuel the growth of prostate cancer cells. Several medications achieve this, including luteinizing hormone-releasing hormone (LHRH) agonists like leuprolide (Lupron, Eligard), goserelin (Zoladex), degarelix (Firmagon), and relugolix (Orgovix). These medications work by suppressing testosterone production. Antiandrogens, such as apalutamide (Erleada), darolutamide (Nubeqa), flutamide (Euflex), and enzalutamide, block the action of androgens at the cancer cell level. Abiraterone acetate (Zytiga) further inhibits androgen production within the cancer cells themselves.

Chemotherapy: Systemic Attack on Cancer Cells

Chemotherapy utilizes drugs to halt the growth of cancer cells, either by killing them or preventing their division. Docetaxel (Taxotere) is the most commonly used chemotherapy drug for prostate cancer, often administered alongside steroids to enhance its effectiveness. If docetaxel proves ineffective, cabazitaxel (Jevtana) may be considered.

Targeted Therapy: Precision Strikes Against Cancer

Targeted therapies focus on specific vulnerabilities within cancer cells. PARP inhibitors, like olaparib (Lynparza), block an enzyme involved in DNA repair, showing promise for men with mutations in genes such as BRCA1 or BRCA2. Clinical trials are continually exploring latest targeted therapies.

Immunotherapy: Harnessing the Body’s Immune System

Immunotherapy leverages the patient’s own immune system to fight cancer. Sipuleucel-T (Provenge) is an immunotherapy approved for treating prostate cancer that has spread, stimulating the immune system to recognize and attack cancer cells.

Surgical Interventions: Removing or Modifying the Prostate

Surgery may be an option for men with otherwise good health and tumors confined to the prostate gland. Several surgical approaches are available:

• Radical Prostatectomy: This involves the complete removal of the prostate gland, surrounding tissues, and seminal vesicles. It can be performed through traditional open surgery, laparoscopically, or with robotic assistance.
• Pelvic Lymphadenectomy: This procedure removes lymph nodes in the pelvis to determine if cancer cells have spread.
• Transurethral Resection of the Prostate (TURP): This minimally invasive procedure removes excess prostate tissue through the urethra, often used to relieve urinary symptoms.
• Cryosurgery or Cryotherapy: Currently available primarily within clinical trials, this technique uses extreme cold to freeze and destroy cancer cells.

Radiation Therapy: Using High-Energy Rays to Destroy Cancer

Radiation therapy employs high-energy X-rays or other forms of radiation to kill cancer cells. There are two main types:

• External Radiation Therapy: Radiation is delivered from a machine outside the body, precisely targeted at the tumor. Techniques like conformal radiation and hypofractionated radiation are used to maximize effectiveness and minimize side effects. Proton therapy, a more precise form of external radiation, may further reduce side effects.
• Internal Radiation Therapy (Brachytherapy): Radioactive seeds, needles, or wires are placed directly into or near the cancer.
• Radiopharmaceutical Therapy: A radioactive substance is injected into the bloodstream to target cancer cells, such as radium-223 for prostate cancer that has spread to the bone.

Active Surveillance and Watchful Waiting: A Conservative Approach

For some men, particularly those with slow-growing cancer or other health concerns, active surveillance or watchful waiting may be appropriate. Watchful waiting involves monitoring the condition without immediate treatment until symptoms develop, typically reserved for men with limited life expectancy. Active surveillance involves more frequent monitoring, including regular PSA tests and biopsies, to postpone definitive treatment until signs of progression emerge. The Prostate Cancer Foundation provides resources for finding clinical trials.

Managing Erectile Dysfunction: Addressing a Common Side Effect

Treatment for prostate cancer can often lead to erectile dysfunction. But, many men experience a return of sexual function within two years of treatment, although the extent of recovery varies. Options for managing erectile dysfunction include oral medications (sildenafil, tadalafil, vardenafil, avanafil), locally applied therapies, vacuum erection devices, and penile implants.

Finding Clinical Trials

For men considering participation in a clinical trial, resources are available to assist identify open trials in their area and across the country. Memorial Sloan Kettering Cancer Center is a leading research institution actively testing new treatments for prostate cancer. The Prostate Cancer Clinical Trials Consortium (PCCTC), sponsored by the Prostate Cancer Foundation and the Department of Defense, also offers a comprehensive list of ongoing studies. One such trial, LEGION-100, is evaluating SYNC-T Therapy SV-102 for metastatic castration-resistant prostate cancer, combining tumor freezing with targeted drug delivery to stimulate the immune system.

Navigating prostate cancer treatment requires a collaborative approach between patient and healthcare team. Understanding the available options, potential side effects, and the role of clinical trials is crucial for making informed decisions and achieving the best possible outcome.
