For example, when leuprolide debuted way back in 1985, it was a daily injection. But four years later, they developed the monthly depo formulation. Now we have formulations that are approved for administration once only every three, four, and even six months,\u201d Andrew Ruplin, PharmD, clinical oncology pharmacist at Fred Hutchinson Cancer Center in Seattle, WA, told Jaime Weimer, MSN, RN, AGCNS-BS, AOCNS\u00ae, manager of oncology nursing practice at ONS, during a conversation about the luteinizing hormone\u2013releasing hormone (LHRH) antagonist and agonist drug classes.

Highlights From This Episode \u201cBetween all of these agonists and antagonists, there\u2019s a broad spectrum of applications, including hormone-positive breast cancer, androgen-deprivation therapy for prostate cancer, uterine cancer, and then other non-cancer uses like uterine fibroids, and assisted reproduction fertility treatments, and other things too.\u201d TS 3:24 \u201cIn the education of my female patients, I basically use the analogy that it is functionally inducing menopause in that person, so there can be changes to mood and cognition, energy level fatigue, body morphology, and shifts in fat distribution metabolism, which can unfortunately increase the risk of cardiovascular disease. One that almost everyone\u2019s familiar with is hot flashes, but also changes to bone mineral density, libido and physically to atrophy and dryness of vaginal mucosa, which can make sex for our patients more difficult as well.\u201d TS 10:33 \u201cA concept that\u2019s familiar to all professionals in the care of prostate cancer is that because LHRH agonists cause an initial increase in testosterone, which can, in essence, feed the cancer, some patients can experience worsening symptoms of their cancer, such as difficulty voiding their bladder pain, or even vertebral collapse or spinal cord compression when bone metastases are present. This is a really serious issue that should be considered ahead of starting an agonist in these patients.\u201d TS 12:39 \u201cI don\u2019t think we\u2019ll see any dramatic changes in treating breast cancer, since the role of these agents is a lot more limited and simply really exist to suppress estrogen and premenopausal patients. But as a referral center that routinely sees patients with breast cancer and their 40s and 30s and even their 20s, it\u2019s crucial to consider these agents in their role for not only actively treating certain types of breast cancer, but also in preserving fertility for patients who desire to have children and they are receiving gonadotoxic chemotherapy.\u201d TS 25:32 ","author_name":"The ONS Podcast","author_url":"http:\/\/onsvoice.libsyn.com\/website","html":"
