Coping with Metastasized Prostate Cancer

Metastasized prostate cancer (which is more commonly referred to as metastatic prostate cancer or prostate cancer metastasis), means that the cancer has spread from its original site (the prostate gland) to the lymph nodes, other organs of the body, or the bones (such as the spine, pelvis, ribs or bones of the arms or thighs).

Some use the term advanced metastatic prostate cancer, but generally the word “advanced” is used to describe locally advanced cancer, which is cancer that has grown through the outer rim of the prostate and into nearby tissue. But others may use the word advanced to describe metastasized prostate cancer, which is cancer that has spread beyond the prostate gland and nearby tissue. So the terms advanced metastatic prostate cancer and advanced prostate cancer can be a little confusing. When we refer to metastatic disease, we mean prostate cancer that has spread beyond the gland and nearby tissue.

Treatments for metastasized prostate cancer

The most common or “mainstay” treatment for metastasized prostate cancer has been hormone therapy (often called androgen suppression therapy or ADT, which stands for androgen deprivation therapy). While this is not considered to be a curative treatment for metastatic disease, it has been shown to extend survival in men. Unfortunately, at some point the cancer usually “learns” to grow again and no longer responds to hormone treatment. This is known as hormone-refractory prostate cancer or androgen-independent cancer.

Because of the eventual resistance to hormone treatment, there has been much debate over the years about whether men should start ADT right away (even before a man has any evidence of metastasized prostate cancer) or whether he should wait until he definitely has metastatic disease. Laboratory studies have suggested that early hormone therapy does not mean a man will experience early resistance, but the jury is still out on this (and more research is needed).

However, a very early study by Crawford et al showed a benefit of early hormone therapy in men with distant metastases (which means cancer has spread from the prostate gland to distant organs or distant lymph nodes). More recently, Moul et al suggested the potential benefit of early hormone therapy in delaying clinical metastasis, based on their database analysis of 5,382 men who underwent primary radical prostatectomy. But as we said, more clinical research is needed in this area, particularly since many men find the side effects of ADT to be difficult to live with.

Other treatments for prostate cancer metastasis

  • External beam radiation: this is sometimes is used to treat prostate cancer metastasis, particularly when men experience bone pain
  • Chemotherapy: such as the use of docetaxel (Taxotere®), which is often used along with prednisone. More recently, the FDA has approved the chemotherapy drug, Jevtana® (cabazitaxel) injection, in combination with the steroid prednisone for men with metastatic prostate cancer that has not responded to hormone deprivation therapy or treatment with docetaxel
  • Radiopharmaceuticals: drugs that are used to fight bone pain caused by prostate cancer metastases. Sometimes other pain medications are also used
  • Bisphosphonates: these drugs are used to keep bones from breaking down and to treat bone pain

Vaccine therapy

An exciting development for metastasized prostate cancer is emerging immunotherapies, such as vaccines.

One such treatment that has been approved by the FDA for use in men with advanced cancer is Provenge® (sipuleucel-T).

Provenge is the first in a new class of active cellular immunotherapies, and is designed to engage a man’s own immune system against prostate cancer.

With Provenge, a man's white blood cells are first removed from his blood. These cells are then exposed to a specific protein from prostate cancer cells. This protein is called prostatic acid phosphatase or PAP. The altered cells are then given back to the man in three intravenous doses, with a period of two weeks between each dose.

The most common (and temporary) side effects that have been reported with Provenge include fever, chills, fatigue, and back and joint pain. Rare symptoms, which have improved with treatment, have included problems breathing and high blood pressure.

In clinical trial, Provenge was shown to extend median survival by 4.1 months compared to placebo (25.8 months versus 21.7 months) and increased 3-year survival by 38% (31.7% versus 23.0% for placebo).
