Advanced Prostate Cancer: The Basics and Treatment Optionsby Jay Motola, M.D. Health Professional
Patients with prostate cancer that is not localized to the prostate and has spread cannot be cured of their disease. However, many treatments are now available that help prolong overall survival in patients with metastatic disease. Here are the basics you need to know, as well as treatment options.
Hormonally sensitive prostate cancer
Responds to the elimination of the male hormone testosterone by various medications.
Hormonally refractory prostate cancer
Does not respond to medications which eliminate the male hormone testosterone; other medications are now available to treat this kind of prostate cancer.
Treatment outlook for hormonally sensitive prostate cancer
–Patients are first put on medications known as LHRH antagonists, and possible antiandrogens.
–For a period of time patients respond favorably and symptoms such as pain decrease.
–Over time these medications become ineffective and the patients develop hormonally resistant prostate cancer.
Treatment outlook for hormonally refractory prostate cancer
–Despite receiving medications to block testosterone, the disease progresses and the PSA rises.
–Several treatments are available such as immunotherapy, oral agents, IV agents, and bone agents.
What is immunotherapy?
–For patients with asymptomatic or minimally symptomatic metastatic castrate-resistant (hormonally refractory) prostate cancer
–Involves treating your own immune cells, and activates portions of the immune system to fight the cancer
–Prolongs survival beyond 2 years in patients
What are oral agents?
–Work by blocking enzymes in the liver that are involved with the synthesis of testosterone, or by blocking the site that androgens react with
–Taken in conjunction with LHRH medications
What is IV medication?
–Disturbs cell division
–Used in patients either failing oral therapies or, for some, prior to their usage
–Side effects potentially more significant than oral agents
What are bone agents?
–Kills cancer cells in metastatic bone lesions
–Radioactive substance that is administered intravenously
–Prolongs life by over 4 months
