Episode 413: Intrarenal Administration for Upper Urothelial Tract Disease: The Oncology Nurse’s Role
The ONS Podcast
“We thought, from a nursing standpoint, ‘What is our goal for doing this?’ What we wanted was first, education of the patient. Can we successfully educate the patient to prepare them? Can we alleviate as much anxiety as possible so that they feel comfortable coming in and having this done? The second goal is to preserve kidney function throughout the treatment. To date, we’ve been successful with that. And the third goal is to complete treatment without infection,” ONS member Chris Amoroso, BSN, RN, OCN®, registered nurse at Fox Chase Cancer Center in Philadelphia, PA, told Jaime...

Episode 412: Pharmacology 101: Cytokines
The ONS Podcast
“They are small, powerful little nuggets. They are actually small signaling proteins that our immune cells use to communicate. They really help regulate immune activation or inflammation and even the growth and survival of immune cells. When cytokines are used therapeutically in oncology, they help to stimulate immune cells such as T cells or natural killer cells to better recognize and attack cancer cells,” Maribel Pereiras, PharmD, BCPS, BCOP, clinical pharmacy specialist at the John Theurer Cancer Center of Hackensack University Medical Center in New Jersey, told Jaime Weimer, MSN,...

Episode 411: An Overview of Myelodysplastic Syndrome for Oncology Nurses
The ONS Podcast
“Not every patient with myelodysplastic syndrome (MDS) is going to progress and die. Only 10%–20% of them will evolve into acute myeloid leukemia. And not all of them need blood transfusions. Some present with low platelet count. It’s not just people who are anemic that have MDS—it’s different depending on what type of MDS they have. These are averages. We’re giving you statistics based on averages, and you’re an individual, so we want to treat you as an individual,” ONS member Sara Tinsley-Vance, PhD, APRN, AOCN®, nurse practitioner and quality-of-life researcher at Moffitt...

Episode 410: The Evidence for the Environment’s Impact on Cancer Outcomes
The ONS Podcast
“Cancer and environmental disasters in particular, but the worsening of our environment, are really things that are great equalizers. And we recognize that we’re all kind of in this world together. We can really face these issues on a more human level. I think always recognizing that if we look at something, we think, ‘Well, that doesn’t relate to me or that problem is it really isn’t my problem’—it sure is,” ONS member Margaret “Peggy” Rosenzweig, PhD, CRNP-C, AOCNP®, FAAN, ONS scholar-in-residence and distinguished service professor of nursing and Nancy Glunt Hoffman...

Episode 409: An Overview of Interventional Oncology for Nurses
The ONS Podcast
“Interventional oncology has really evolved into an important component of modern cancer care and is often described now as the fourth pillar alongside medical, surgical, and radiation oncology. The specialty now encompasses a broad spectrum of image-guided procedures that support from cancer diagnosis, treatment, to effectively managing symptoms that are caused by the disease. In other words, what we’re seeing is that across the continuum of care, IO is playing a vital role,” ONS member Evelyn P. Wempe, DNP, MBA, APRN, ACNP-BC, AOCNP®, CRN, NEA-BC, executive director for advanced...

Episode 408: Radiation Site-Specific Side Effects: Breast Cancer
The ONS Podcast
“A side effect patients might experience is lymphedema. This is an increased buildup of lymphatic fluid in the tissues, either in the breast or in the arm and hand of the affected side. It’s quite problematic for women. They might feel self-conscious. It might feel uncomfortable that the arm feels like it’s throbbing or heavy. Clothing may not fit quite right. So we’re always on the lookout for lymphedema,” Maria Fenton-Kerimian, APRN, AOCNP®, nurse practitioner at Weill Cornell Medicine in New York, told Jaime Weimer, MSN, RN, AGCNS-BS, AOCNS®, manager of oncology nursing practice...

Episode 407: Pharmacology 101: CAR T-Cell Immunotherapy
The ONS Podcast
“You want to try to act quickly and be able to know what the pathways are for appropriate escalating when a patient is having symptoms that are reflective of cytokine release syndrome (CRS) or neurotoxicity. These toxicities are very manageable and treatable when recognized early. To summarize, choosing the right patient, knowing the toxicity profile for each product, and acting early is really what helps to prevent severe outcomes with chimeric antigen receptor (CAR) T-cell therapy,” Maribel Pereiras, PharmD, BCPS, BCOP, clinical pharmacy specialist at the John Theurer Cancer Center at...

Episode 406: Drug Resistance Biomarkers and Their Impact on Cancer Treatment Choices
The ONS Podcast
“Our goal of precision oncology has been to shift to tailored therapies that can help to improve treatment efficacy and ultimately improve patient outcomes. Resistance biomarker testing can help the care team to detect these genomic changes that the tumor may have acquired during therapy that makes the cells resistant to therapy. This information can be extremely helpful when we’re talking about making choices about second-line or subsequent-line therapy,” ONS member Danielle Fournier, DNP, APRN, AGPCNP-BC, AOCNP®, advanced practice RN at the University of Texas MD Anderson Cancer...

Episode 405: Long-Term Multiple Myeloma Considerations for Oncology Nurses
The ONS Podcast
“The disease is increasingly managed as a chronic condition rather than a diagnosis with an immediate terminal outcome. Particularly, with earlier and more effective and sustained treatment options, we can make this disease a very chronic, long-term, livable condition. I want to make sure that patients are aware that this is not a death sentence. This is something that patients can live with for the long term,” Ann McNeill, RN, MSN, APN, nurse practitioner at the John Theurer Cancer Center at Jersey Shore University Medical Center in Neptune, NJ, told Lenise Taylor, MN, RN, AOCNS®,...

Episode 404: Tailor Patient Treatment Education for Non-Oncology Indications
The ONS Podcast
“We print education sheets that we have, and we say, ‘Just ignore this part that says cancer. You’re getting this med but for a different indication.’ And then you have to really point out what our goals of care are. You’re using the information that, as oncology nurses, we like and love, but we’re having to cross it out and say, ‘Just read this portion and just do this here.’ And that can be challenging for the nurse and probably confusing for the patient,” ONS member Brandy Thornberry, RN, OCN®, outpatient infusion and VAD supervisor at Logan Health in Kalispell, MT,...
info_outline“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 what causes the cell death,” Kenneth Tham, PharmD, BCOP, clinical pharmacist in general oncology at the University of Washington Medicine and 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 antibody–drug conjugates.

Highlights From This Episode
“The mechanism of action of the chemo itself depends on what agent or what ‘warhead’ is attached. Generally, [ADCs] have some kind of cytotoxic mechanism related to many of the chemotherapies that we use in practice, without attachment to the antibody. Some of them can be microtubule inhibitors, vinca alkaloids like vincristine. Some of them can be topoisomerase I (TOP1) inhibitors like irinotecan. Some can be alkylating agents that cause DNA breaks. So, again, looking back at the arsenal we have of cytotoxic chemo, these can all be incorporated into the ADCs.” TS 5:54
“I want to talk about a case where the biomarker is being tested, but the biomarker isn’t the target that you’re looking for. One good case of this is a newer agent that was approved called datopotamab deruxtecan. The datopotamab portion is specific to a target called ‘trophoblast cell surface antigen 2’ (TROP2), which is expressed on the surface of many epithelial cancers. This agent was first approved in hormone receptor-positive, HER2-negative breast cancer, and received accelerated approval in patients with non-small cell lung cancer (NSCLC) with an EGFR mutation. ... The antibody looks for a target, TROP2. But in both of these cases—in the breast cancer and the NSCLC—you’re testing for expression of different mutations or lack thereof. You’re not looking for expression of TROP2. There’s more research that needs to be done about the relationship between TROP2 expression and the presence or absence of these other biomarkers, but until we know more, we’re actually testing for biomarkers that aren’t the target of the ADC.” TS 10:22
“There are common adverse advents to antibodies and chemo in general. Because we have both of these components, we want to watch out for the adverse effects of both of them. Antibodies, as with most proteins, can trigger an immune response or an infusion reaction. So, many ADCs can also cause hypersensitivity or infusion reactions. The rates of that are really variable and depend on the actual antibodies themselves. Then you have the cytotoxic component, the chemotherapy component, which has its own characteristic side effects. So, if we think of general chemo side effects—fatigue, nausea, bone marrow suppression, alopecia—these can [occur] with a lot of ADCs as well.” TS 15:34
“The rate of ocular toxicity in [mirvetuximab soravtansine] is quite high. The manufacturer reports that this can occur in up to 60% of patients. With rates so high, the manufacturer recommends a preventive strategy. For this particular agent, [they] recommend patients have required eyecare. ... This ocular toxicity is something we do see in other ADCs that don’t have the same target and don’t necessarily have the same payload component. For example, tisotumab vedotin and again, datopotamab deruxtecan, can both cause ocular toxicities and both would have required ocular supportive care.” TS 20:08
“Overall, I feel like the future is incredibly bright for these agents. There have only been around a dozen therapies approved by the U.S. Food and Drug Administration (FDA) despite this idea—the first agent came out in 2000. So, 25 years later, there are only around a dozen FDA-approved treatments. But there are so many more that are coming through the pipeline. And as we’re discovering more biomarkers and developing more specialized antibodies, it’s only natural that more ADCs will follow.” TS 26:50
