Prostate cancer can be treated with various non-surgical methods, offering effective alternatives to traditional surgery. These treatments focus on targeting cancer cells while minimizing damage to healthy tissues. This article explores several non-surgical treatments for prostate cancer.

Radiation Therapy

Radiation therapy uses high-energy rays to kill cancer cells. There are two main types of radiation therapy used for prostate cancer:

  • External Beam Radiation Therapy (EBRT): This method directs radiation at the prostate from outside the body over several weeks.
  • Brachytherapy: Also known as seed knife therapy, this involves placing radioactive seeds directly into the prostate gland.

Hormone Therapy

Hormone therapy, also known as androgen deprivation therapy (ADT), reduces the levels of male hormones (androgens) to slow the growth of prostate cancer cells. This therapy can be used alone or in combination with other treatments.

  • Orchiectomy: Surgical removal of the testicles to reduce androgen levels.
  • LHRH Agonists and Antagonists: Drugs that lower testosterone levels by acting on the pituitary gland.
  • Anti-Androgens: Medications that block the action of androgens on prostate cancer cells.

Immunotherapy

Immunotherapy enhances the immune system's ability to fight cancer. For prostate cancer, several immunotherapy options are available:

  • Checkpoint Inhibitors: Drugs like Pembrolizumab (Keytruda) and Nivolumab (Opdivo) help the immune system recognize and attack cancer cells.
  • Cancer Vaccines: Sipuleucel-T (Provenge) is designed to stimulate the immune system to attack prostate cancer cells.
  • Monoclonal Antibodies: Lab-created molecules that can bind to cancer cells and mark them for destruction by the immune system.

Targeted Therapy

Targeted therapy involves using drugs designed to target specific molecules involved in the growth and spread of cancer cells. Examples include:

  • Enzalutamide (Xtandi): Inhibits the androgen receptor pathway, crucial for prostate cancer cell growth.
  • Abiraterone (Zytiga): Blocks the production of androgens, reducing the fuel for cancer growth.
