Episode 400: Pharmacology 101: Radioimmunoconjugates
The ONS Podcast
“Radioimmunoconjugates work through a dual mechanism that combines immunologic targeting with localized radiation delivery. The monoclonal antibody components bind to specific tumor-associated antigens such as CD20, expressed on malignant B cells. Once found, the attached radioisotope delivers beta radiation directly to the tumor, causing DNA damage and cell death,” Sabrina Enoch, MSN, RN, OCN®, CNMT, NMTCB (CT), theranostics clinical specialist at Highlands Oncology in Rogers, AR, told Jaime Weimer, MSN, RN, AGCNS-BS, AOCNS®, manager of oncology nursing practice at ONS, during a...

Episode 399: National Hazardous Drug Exposure Registry
The ONS Podcast
“The United States does not have a national cancer registry. We have a bunch of state registries. Some of those registries do collaborate and share information, but the issue is the registries that do exist typically do not report cancer by occupation. So, we cannot get our arms around the potential work-relatedness of the health outcome given the current way the state registries collect information. What we’re trying to set up, is a way to make what is currently an invisible risk, visible,” ONS member Melissa McDiarmid, MD, MPH, DABT, professor of medicine and epidemiology and public...

Episode 398: An Overview of Multiple Myeloma for Oncology Nurses
The ONS Podcast
“[Multiple myeloma] is very treatable, very manageable, but right now it is still considered an incurable disease. So, patients are on this journey with myeloma for the long term. It’s very important for us to realize that during their journey, we will see them repeatedly. They are going to be part of our work family. They will be with us for a while. I think it’s our job to be their advocate. To be really focused on not just the disease, but periodically assessing that financial burden and psychosocial aspect,” Ann McNeill, RN, MSN, APN, nurse practitioner at the John Theurer Cancer...

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...
info_outline“Next-generation sequencing, or NGS, can be used to help us determine if the patient has specific biomarkers we can identify and use to target for treatment. Certain findings can tell us if a particular treatment might work for that patient, and we can see if there are any genetic variants we might have a biomarker targeted agent to use to treat them with,” ONS member Jackie Peterson, MSN, RN, OCN®, NE-BC, MBA, ambulatory nurse manager at the University of Chicago Medical Center in Illinois, told Lenise Taylor, MN, RN, AOCNS®, BMTCN®, oncology clinical specialist at ONS, during a conversation about prostate cancer and biomarker testing.

Highlights From This Episode
“Some of the risk factors for developing prostate cancer include age, race, family history, and certain genetic changes or variants. Prostate cancer has some hereditary components, but most prostate cancer occurs in men without any significant family history of it.” TS 1:31
“Key biomarkers include PSA and prostate cancer gene 3, which is PCA3, and prostate-specific membrane antigen, or PSMA. Other biomarkers that are important for us to test include BRCA1, BRCA2, and Lynch syndrome–associated genes, which are MLH1, MSH2, MSH6, PMS2, and EPCAM. Biomarkers can be collected via your blood, urine, saliva, or tissue samples, so these are different ways that we can test and look for biomarkers in our patients.” TS 3:24
“It does matter how advanced the disease is. Usually, for our castrate-sensitive patients, they respond better to androgen deprivation therapy because that really is slowing down the growth of the cancer by reducing the available testosterone that the cancer needs to grow. Whereas our patients that are more advanced and have castrate-resistant prostate cancer, that cancer will continue to grow despite having the lowered testosterone levels, so they might need additional layers of treatment to really get their cancer under control.” TS 7:50
“When I talk to [patients] about biomarker testing, I tell them it’s another tool in our toolbox that we can use to help us determine if they might benefit from other therapy options now or in the future. I tell them that sometimes we’ll get a report back with a variant of unknown significance, and basically that means that we don’t really know whether or not this has an impact on their health or risk factors for the disease. That can sometimes be a little bit of a concern for these patients, so we just have to reassure them that we’re continually doing research around biomarker testing. The science is always advancing, so if there’s something that [researchers] find in the future, we’ll make them aware of that.” TS 9:08
“One of the biggest topics I think about is the inequity that exists in biomarker testing and research, especially surrounding the African American population. When these tests were developed, that population really wasn’t studied as much, so there’s not a lot of good data yet to make a decision or impact on those patients and that population.” TS: 12:30
