Stage IV is the last stage of prostate cancer and the diagnosis shows a tumor that has spread to other parts of the body, including the lymph nodes, lungs, liver, bones, or bladder. Patients affected with such type of cancer have a survival rate of 29% for five years. But, keep in mind, the survival rate of prostate cancer is very high compared to other types of cancers since it is a slow moving disease. The majority of men who are diagnosed with prostate cancer in Kansas City will pass away due to an unrelated cause.
Causes of Prostate Cancer
– Men over 50 years of age develop the risks of prostate cancer
– Researchers report that there may be a link between obesity and prostate cancer
– Men who skip exercise have been found to be at higher risk of developing prostate cancer.
– A diet high in calcium is linked to an increased risk of developing prostate cancer.
– Trouble urinating
– Decreased force in the stream of urine
– Blood in the semen
– Discomfort in the pelvic area
– Bone pain
– Erectile dysfunction
Prostate cancer that has been spread to distant organs is treatable but is not curable. The different treatment options available for metastatic stage IV prostate cancer includes,
– Hormone Therapy
Hormone therapy lowers the male hormone levels that are responsible for the growth of prostate cancer. This type of treatment can be achieved with orchiectomy or luteinizing hormone-releasing hormone (LHRH) analogs, alone or in combination with an anti-androgen.
For the treatment of metastatic prostate cancer, newer hormonal medications that inhibit the synthesis of androgen and block androgen receptor signaling are now FDA approved.
Like hormone therapy, chemotherapy is a systemic therapy which injects cancer-fighting drugs to circulate in the blood to parts of the body that are affected by cancer cells. This technique kills or eliminates cancers cells at sites great distances from the original cancer. Chemotherapy drugs like mitoxantrone, docetaxel, paclitaxel and estramustine have been demonstrated as having the ability to kill prostate cancer cells in patients with advanced prostate cancer. Recently, several other advanced chemotherapies and targeted therapy drugs have been approved for the treatment of prostate cancer designed to treat only the cancer cells and minimize damage to normal, healthy cells.
Immunotherapy also called as immunologic therapy or biotherapy, is a type of prostate cancer treatment in Kansas City that uses the body’s immune system to facilitate the killing of cancer cells. Different types of biological therapy includes,
– Interferon, interleukin
– Monoclonal antibodies
– Colony stimulating factors
In some patients, the combination of radiation and immediate hormonal therapy appear to increase the survival rate.
