Hormonal therapy in prostate cancer: historical approaches
Abstract:
Hormonal therapy has been the standard of care for advanced prostate cancer for over 6 decades. Treatments to suppress testosterone have expanded beyond surgical castration and estrogens to include steroidal and nonsteroidal antiandrogens, luteinizing hormone-releasing hormone agonists, and, most recently, gonadotropin-releasing hormone antagonists. Yet, despite this extensive therapeutic armamentarium, long-term survival of patients with advanced prostate cancer remains poor. Many issues regarding hormonal treatment of prostate cancer continue to be controversial, including the benefits of combined androgen blockade versus monotherapy, the optimal timing of treatment, and the value of new therapeutic approaches and strategies, such as intermittent androgen deprivation and adjuvant chemotherapy.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Cancer Vaccines
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
