New Approaches to Prostate Cancer Treatment in 2017 – Immunotherapy, Targeted Therapy, and Integrative Strategies

Overview of Prostate Cancer

Prostate cancer is a common form of cancer that affects the prostate gland, a small walnut-shaped organ in men that produces seminal fluid. According to the American Cancer Society, prostate cancer is the second most common cancer in men, with an estimated 191,930 new cases diagnosed in 2020 in the United States alone.

Prostate cancer typically grows slowly and may not cause significant symptoms in its early stages. However, as the cancer advances, it can spread to other parts of the body, such as the bones, and cause more serious complications.

Key Facts about Prostate Cancer:

  • Prostate cancer is more common in older men, with the average age of diagnosis around 66 years old.
  • African American men and men with a family history of prostate cancer are at a higher risk of developing the disease.
  • Regular screenings, such as prostate-specific antigen (PSA) tests and digital rectal exams, can help detect prostate cancer early.
  • Treatment options for prostate cancer include active surveillance, surgery, radiation therapy, hormone therapy, chemotherapy, and newer approaches like immunotherapy and targeted therapy.

It is essential for men to be aware of the risk factors for prostate cancer and to discuss screening options with their healthcare providers. Early detection and treatment can significantly improve outcomes for patients with prostate cancer.

Traditional Treatment Options for Prostate Cancer

Prostate cancer is a significant health concern for men worldwide, with various treatment options available depending on the stage and aggressiveness of the disease.

Surgery:

Surgical removal of the prostate gland, known as radical prostatectomy, is a common treatment option for localized prostate cancer. This procedure aims to remove the cancerous tissue while preserving surrounding structures.

Radiation Therapy:

Radiation therapy uses high-energy rays or particles to destroy cancer cells. It can be delivered externally or internally through brachytherapy. Radiation therapy is often used as a primary treatment or in combination with surgery.

Hormone Therapy:

Also called androgen deprivation therapy, hormone therapy aims to reduce levels of male hormones (androgens) that stimulate prostate cancer growth. This treatment is commonly used for advanced or metastatic prostate cancer.

Chemotherapy:

Chemotherapy uses drugs to kill rapidly dividing cells, including cancer cells. While not typically used as a first-line treatment for prostate cancer, it may be recommended for advanced cases that are hormone-resistant.

Active Surveillance:

For low-risk prostate cancer, active surveillance involves closely monitoring the cancer with regular tests and check-ups instead of immediate treatment. This approach is suitable for some patients to avoid unnecessary side effects of treatment.

“According to the American Cancer Society, more than 174,000 new cases of prostate cancer are expected in the United States in 2022, highlighting the importance of effective treatment strategies.”
