A nurse is caring for a client who has advanced stage prostate cancer. The nurse should expect the provider to prescribe which of the following medications for this client?
A.
Tamoxifen
B.
Leuprolide
C.
Cyclophosphamide
D.
Finasteride
The Correct Answer and Explanation is:
The correct answer is B. Leuprolide.
Explanation:
Advanced stage prostate cancer often requires a multifaceted treatment approach, including hormonal therapy, to manage the progression of the disease. Among the medications listed, Leuprolide is the most appropriate choice for a client with advanced prostate cancer.
Leuprolide is a luteinizing hormone-releasing hormone (LHRH) agonist. Its primary function is to reduce the levels of testosterone in the body. Since prostate cancer growth is often fueled by testosterone, lowering testosterone levels can help slow down the progression of the disease. Leuprolide works by initially stimulating the pituitary gland to release more luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This results in a temporary increase in testosterone levels, but after continuous administration, it leads to a suppression of these hormones due to downregulation of the pituitary gland. Consequently, this reduction in testosterone levels helps in managing advanced prostate cancer.
Tamoxifen is primarily used for treating breast cancer, not prostate cancer. It is a selective estrogen receptor modulator (SERM) that blocks estrogen receptors, which is effective in hormone receptor-positive breast cancer but not indicated for prostate cancer.
Cyclophosphamide is a chemotherapy agent used to treat various types of cancer, including some forms of leukemia and lymphoma. While it is used in cancer treatment, it is not the first-line medication for prostate cancer, especially in its advanced stages.
Finasteride is a 5-alpha reductase inhibitor that is used to treat benign prostatic hyperplasia (BPH) and sometimes for early-stage prostate cancer. However, it is not typically used for advanced prostate cancer where hormone therapy like leuprolide is preferred.
In summary, Leuprolide is the most suitable medication among the options for managing advanced stage prostate cancer due to its effectiveness in reducing testosterone levels, which is crucial in controlling the progression of the disease.
