Episode 397: Cancer Symptom Management Basics: Ototoxicity
The ONS Podcast
“Referring patients to audiology early on has shown dramatic reduction in hearing loss or complications because the audiologist can really see where were they at before they started chemotherapy, where were they at during, if they get an audiogram during their treatment. And then after treatment, it’s really important for them to see an audiologist because this is really a survivorship journey for them. And as nurses, the ‘so what’: We are the first line of defense,” ONS member Jennessa Rooker, PhD, RN, OCN®, director of nursing excellence at the Tampa General Hospital Cancer...

Episode 396: Nursing Considerations From the ONS/ASCO Extravasation Guideline
The ONS Podcast
“We proposed a concept to the American Society of Clinical Oncology (ASCO), recognizing that extravasation management requires significant interdisciplinary collaboration and rapid action. There can occasionally be uncertainty or lack of clear guidance when an extravasation event occurs, and our objective was to look at this evidence with the expert panel to create a resource to support oncology teams overall. We hope that the guideline can help mitigate harm and improve patient outcomes,” Caroline Clark, MSN, APRN, AGCNS-BC, OCN®, EBP-C, director of guidelines and quality at ONS, told...

Episode 395: Pharmacology 101: Monoclonal Antibodies
The ONS Podcast
“They [monoclonal antibodies] are able to cause tumor cell death by binding to and blocking to necessary growth factor signaling pathways for tumor cell survival. That’s going to be dependent on the target of the antibody, but I’ll give an example of epidermal growth factor, or EGFR. This is overexpressed in several different kinds of cancers where activation of this growth factor increases the amount of proliferation and migration of cancer cells. So, if we bind to it and block to it, then that would help halt these pathways and stop cancer cell growth,” Carissa Ganihong, PharmD,...

Episode 394: Prostate Cancer Survivorship Considerations for Nurses
The ONS Podcast
“The thought of recurrence is also a psychosocial issue for our patients. They’re being monitored very closely for five years, so there’s always that thought in the back of their head, ‘What if the cancer comes back? What are the next steps? What am I going to do next?’ It’s really important that we have conversations with patients and their families about where they’re at, what we’re looking for, and reassure them that we’ll be with them during this journey and help them through whatever next steps happen,” ONS member Clara Beaver, DNP, RN, AOCNS®, ACNS-BC, manager...

Episode 393: Antibody–Drug Conjugates in Metastatic Breast Cancer
The ONS Podcast
“I’ll go back to the backpack analogy. When your kids come home with a backpack, all of a sudden their homework is not on the desk where it’s supposed to be. It’s in the kitchen; it kind of spreads all over the place, but it’s still in the house. When we give antibody–drug conjugates (ADCs), the chemotherapy does go in, but then it can kind of permeate out of the cell membrane and something right next to it—another cancer cell that might not look exactly like the cancer cell that the chemotherapy was delivered into—is affected and the chemotherapy goes over to that cancer cell...

Episode 392: ONS 50th Anniversary: Stories From the Other Side of Cancer
The ONS Podcast
“Working as an oncology infusion nurse, being oncology certified, attending chapter meetings, going to ONS Congress® has really taught me plenty. But being an oncology patient taught me way more. I know firsthand the fears ‘you have cancer’ brings. Then going through further testing, CT scans, MRIs, genetics, the whole preparation for surgery was something I never considered when I treated a breast cancer patient,” ONS member Catherine Parsons, RN, OCN®, told Valerie Burger, MA, MS, RN, OCN®, CPN, member of the ONS 50th anniversary planning committee, during a conversation about...

Episode 391: Pharmacology 101: Antibody–Drug Conjugates
The ONS Podcast
“Antibody–drug conjugates (ADCs) have three basic parts: the antibody part, the cytotoxic chemo, and the linker that connects the two. First, the antibody part binds to the target on the surface of the cell. Antibodies can be designed to bind to proteins with a very high level of specificity. That’s what gives it the targeted portion. Then the whole thing gets taken up by the cell and broken down, which releases the chemotherapy part. Some sources will call this the ‘payload’ or the ‘warhead.’ That’s the part that’s attached to the ‘heat-seeking’ part, and that’s...

Episode 390: Prostate Cancer Treatment Considerations for Nurses
The ONS Podcast
“Any time the patient hears the word ‘cancer,’ they shut down a little bit, right? They may not hear everything that the oncologist or urologist, or whoever is talking to them about their treatment options, is saying. The oncology nurse is a great person to sit down with the patient and go over the information with them at a level they can understand a little bit more. To go over all the treatment options presented by the physician, and again, make sure that we understand their goals of care,” ONS member Clara Beaver, DNP, RN, AOCNS®, ACNS-BC, manager of clinical education and...

Episode 389: Biomarker Testing for Non-Small Cell Lung Cancer
The ONS Podcast
“It’s critical to identify those mutations found that are driving the cancer’s growth and guide the personalized treatment based on those results. And important to remember, too, early testing is crucial for patients with non-small cell lung cancer (NSCLC). In studies, it has been found to be associated with improved survival outcomes and reduced mortality,” ONS member Vicki Doctor, MS, BSN, BSW, RN, OCN®, precision medicine director at the City of Hope Atlanta, GA, Chicago, IL, and Phoenix, AZ, locations, told Jaime Weimer, MSN, RN, AGCNS-BS, AOCNS®, manager of oncology nursing...

Episode 388: ONS 50th Anniversary: Milestones in Oncology Advocacy and Health Policy
The ONS Podcast
“I think we really need to push more of our oncology nurses to get into elected and appointed positions. So often we’re looking at health positions to get involved in, and those are wonderful. We need nurses as secretaries of health, but there are others. We as nurses understand higher education. We understand environment. We understand energy. So I think we look broadly at, what are positions we can get in? Let’s have more nurses run for state legislative offices, for our House of Representatives, for the U.S. Senate,” ONS member Barbara Damron, PhD, LHD, RN, FAAN, told Ryne Wilson,...
info_outline“A lot of the efforts have been made to improve the patient experience for these treatments, as they can be given for years at a time. 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,” Andrew Ruplin, PharmD, clinical oncology pharmacist at Fred Hutchinson Cancer Center in Seattle, WA, told Jaime Weimer, MSN, RN, AGCNS-BS, AOCNS®, manager of oncology nursing practice at ONS, during a conversation about the luteinizing hormone–releasing hormone (LHRH) antagonist and agonist drug classes.

Highlights From This Episode
“Between all of these agonists and antagonists, there’s 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.” TS 3:24
“In 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’s 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.” TS 10:33
“A concept that’s 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.” TS 12:39
“I don’t think we’ll 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’s 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.” TS 25:32
