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“Colorectal cancer treatment is not just about eliminating a disease. It’s about preserving life quality and empowering patients through every phase. So I think nurses are really at the forefront that we can do that in the oncology nursing space. So from early detection to survivorship, the journey is deeply personal. Precision medicine, compassionate care, and informed decision-making are reshaping outcomes. Treatment’s just not about protocols. It’s about people,” ONS member Kris Mathey, DNP, APRN-CNP, AOCNP®, gastrointestinal medical oncology nurse practitioner at The James Cancer Hospital of The Ohio State University Wexner Medical Center in Columbus, told Jaime Weimer, MSN, RN, AGCNS-BS, AOCNS®, manager of oncology nursing practice at ONS, during a conversation about colorectal cancer treatment.

Highlights From This Episode
“Colorectal cancer has several different types, but there is one that dominates the landscape, and that is adenocarcinoma. So I think most of us have heard that. It’s fairly common, and it accounts for about 95% of all colorectal cancers. It begins in the glandular cells lining the colon or rectum and often develops from polyps, in particular adenomatous polyps.” TS 1:41
“One of the biomarkers that we’ll most commonly hear about is KRAS or NRAS mutations. This indicates tumor genetics, and these mutations suggest resistance to our EGFR inhibitors such as cetuximab. BRAF mutation or V600E is a more aggressive tumor subtype, and those may respond to our BRAF targeted therapy. … And then our MSI-high or MMR-deficient—microsatellite instability or mismatch repair deficiency—that really predicts an immunotherapy response and may indicate Lynch syndrome, which is a huge genetic component that takes a whole other level of counseling and genetic testing with our patients as well.” TS 6:02
“Polypectomy or a local excision—that removes our small tumors or polyps during that colonoscopy. And that’s what’s used for those stage 0 or early stage I cancers. A colectomy removes part or all of the colon. This may be open or laparoscopic. It can include a hemicolectomy, a segmental resection, or a total colectomy, so where you take out the entire part of the colon. A proctectomy removes part or all of the rectum. This may include a low anterior resection, also known as an LAR … or an abdominal perineal resection, which is an APR. … Colostomy or ileostomy—that diverts the stool to an external bag via stoma. Sometimes this is temporary or permanent depending on the type of surgery.” TS 14:11
“We’ll have our patients say, ‘Hey, I want immunotherapy therapy. I see commercials on it that it works so well.’ We have to make sure that these patients are good candidates for it, also that we’re treating them adequately. We need to make sure that they have those biomarkers, so as I mentioned, the MSI-high or MMR tumors. Our MSS-stable tumors—they may benefit from newer combinations or clinical trials. Metastatic disease—immunotherapy may be used alone or with other treatments. And then in the neoadjuvant setting, some trials are really showing promising results using immunotherapy prior to surgery.” TS 25:38
“Antibody-drug conjugates are really an exciting frontier in all cancer treatments as well as colorectal cancer treatment. This is used mainly for patients with advanced or treatment-resistant disease, and these therapies combine the targeted power of monoclonal antibodies with the cell-killing ability of potent chemotherapy agents. They’re still on the horizon for the most part in colorectal cancer. However, there is only one approved antibody-drug conjugate, or ADC, at this time, and that’s trastuzumab deruxtecan, or Enhertu. That’s approved for any solid tumor, such as colorectal cancer with HER2 IHC 3+. So again, looking back at that pathology in those markers, making sure that you have that HER2 mutation and that IHC.” TS 35:00
“There are a few myths going around about colorectal cancer treatment that can lead to confusion or even delayed care. One myth is only older men get colorectal cancer. As you heard me talk in my previous podcast on screening, unfortunately, this isn’t necessarily true. Colorectal cancer affects both men and women and our cases in the younger population are rising. So our screening guidelines have changed to age 45 because we are seeing it in the younger population.” TS 45:54
