Episode 429: Radiation Site-Specific Side Effects: CNS Cancers
The ONS Podcast
“They’re really worried that radiation is going to be painful. So they come in for that first day of treatment very anxious. With our patients with brain cancer, we’re using the masks on the table, and those masks are very tight and hold their heads very, very still. So they’ll be very worried about being claustrophobic. We may start out the first day or two with a little bit of [lorazepam]. And they’ll come to me and they’ll say, ‘This really hasn’t been as bad as I thought it was going to be,’” ONS member Catherine McCluskey, BSN, RN, OCN®, ROCN™, radiation oncology...

Episode 428: Chronic Lymphocytic Leukemia Treatment Considerations for Oncology Nurses
The ONS Podcast
“Measurable residual disease is where I think the terminology fits best in that, it is intended to measure the amount of cancer cells that are present in the blood or bone marrow at the time the sample was collected. We can identify one cancer cell in a million. Where that can be really valuable is when we start to think about the duration of treatments and the response to some of our treatments,” ONS member Caitilin Murphy, DNP, APRN, FNP-BC, AOCNP®, chief nurse practitioner at Dana-Farber Cancer Institute in Boston, MA, told Lenise Taylor, MN, RN, AOCNS®, TCTCN™, oncology clinical...

Episode 427: Pharmacology 101: Resistance Pathways
The ONS Podcast
“A good way of thinking about this is this is the survival of the fittest clone. There could be a portion of a cancer that naturally has some resistance or ability to survive a particular drug. And over time, as the other cells around it are dying off, that particular clone is able to replicate and continue to survive in the face of that drug therapy and eventually take over as being the fittest clone. At that point, we’re often seeing disease progression,” Danielle Roman, PharmD, BCOP, manager of clinical pharmacy services at the Allegheny Health Network Cancer Institute in Pittsburgh,...

Episode 426: Tools to Support Patients and Nurses Through Medical Trauma in Oncology
The ONS Podcast
“When people with PTSD [post-traumatic stress disorder] get quite avoidant—and that can be expressed in so many different ways—the implications can be really profound. I think an important invitation to oncologists and oncology nurses and primary care providers who care for people battling cancer is let’s explore what's underneath these avoidant behaviors. Is it a very practical thing? Or is it that underneath this avoidant behavior is really profound fear?” James C. Jackson, PsyD, research professor at Vanderbilt University Medical Center in Nashville, TN, told Lenise Taylor, MN,...

Episode 425: How AI Can Help Healthcare Organizations Improve the Cancer Experience
The ONS Podcast
“In oncology specifically, where care is complex, artificial intelligence (AI) can really synthesize large volumes of clinical information, flag risks such as treatment complications, and support adherence to evidence-based pathways. For nurses specifically, this enables them more time for direct patient care, clinical judgment, and care coordination, and really practice to the top of their license while reducing repetitive time and administrative tasks,” Jenn Frith, DNP, RN, OCN®, NE-BC, associate vice president of clinical operations at Duke Cancer Institute in Durham, NC, told Jaime...

Episode 424: Radiation Site-Specific Side Effects: Cancers of the Pelvis
The ONS Podcast
“Think about what organs lie in the radiation field, and anything that lies in that radiation field is likely going to have some potential temporary—hopefully temporary—side effects. If you think about the pelvis, the things that live in there are the bladder, urethra, some bowel, rectum, reproductive organs, skin, some lymph nodes. And so, all of those things could potentially have associated side effects,” ONS member Kayla Kafka-Peterson, BSN, RN, ROCN™, nurse navigator and leader in the brachytherapy and peri-anesthesia programs at UCLA Health, in Los Angeles, CA, told Lenise...

Episode 423: Pharmacology 101: Interaction Pathways
The ONS Podcast
“When we think of drug interactions, specifically, the National Cancer Institute actually defines this as a change in the way a drug acts in the body when taken with certain other drugs, herbals, or foods or when taken with certain medical conditions. Drug interactions may cause the drug to either be more or less effective or cause effects on the body that are not expected,” Carissa Ganihong, PharmD, BCOP, oncology and bone marrow transplantation clinical pharmacist at Hackensack University Medical Center in New Jersey, told Jaime Weimer, MSN, RN, AGCNS-BS, AOCNS®, manager of oncology...

Episode 422: An Overview of Chronic Lymphocytic Leukemia for Oncology Nurses
The ONS Podcast
“What I appreciate about our patients with chronic lymphocytic leukemia (CLL) or small lymphocytic leukemia is the consideration that they receive a cancer diagnosis, and the best thing for them to do is actually nothing. There is a large population of patients that we don’t recommend any type of treatment. We recommend that they establish care with an oncologist and that they have a relationship with those care teams,” ONS member Caitilin Murphy, DNP, APRN, FNP-BC, AOCNP®, chief nurse practitioner at Dana-Farber Cancer Institute in Boston, MA, told Lenise Taylor, MN, RN, AOCNS®,...

Episode 421: Medical Trauma in Oncology
The ONS Podcast
“There are a huge array of medical dynamics that people endure, and when they leave a lasting impact, a word that we don’t use widely enough is the word ‘trauma.’ There’s an entire category of phenomena in the medical arena that are, in fact, traumatic. One way we know that these experiences are traumatic is that we know that huge portions of people who experience things like cancer do indeed develop problems like [post-traumatic stress disorder],” James C. Jackson, PsyD, research professor at Vanderbilt University Medical Center in Nashville, TN, told Jaime Weimer, MSN, RN,...

Episode 420: Long-Term Myelodysplastic Syndrome Considerations for Oncology Nurses
The ONS Podcast
“We typically think of the disease progressing for our higher-risk patients because many of them already start with increased blasts or a lot of dysplasia. And they have these chromosomal variants that make them prone to evolving into acute myeloid leukemia (AML). With them, we can anticipate that they are going to progress to AML. And that’s what we’re trying to prevent. It’s kind of like a biologic evolution and not a switch,” ONS member Sara Tinsley-Vance, PhD, APRN, AOCN®, nurse practitioner and quality-of-life researcher at Moffitt Cancer Center in Tampa, FL, told Lenise...

Highlights From This Episode
“With primary tumors—glioblastomas, astrocytoma, all of those types of cancerous primary CNS tumors, the tumors are not very well-defined. They have little tentacles that kind of go out, so doing something like Gamma Knife, which is very precise, is not as effective as an external beam because the external beam will deliver radiation to all those little tentacles that are out there in the brain. And with Gamma Knife, you really can’t effectively do that.” TS 2:34
“When we’re doing radiation to the brain, fortunately there aren’t that many acute toxicities involved. Sometimes they’ll have some mild dermatitis. Usually, it’s not very significant. They, like everyone else who gets radiation, will have fatigue. Usually once we get to the end of the second week of radiation, into the third week for our patients with primary CNS tumors—the hair loss—they’ll start to notice hair loss just in the treatment area. But those are typical, the things that we’ve seen most. Sometimes we’ll have patients who will experience some nausea, maybe a few headaches, but really the acute toxicities are not severe typically with our patients with brain tumors.” TS 8:30
“[For] the fatigue, I tell patients to just listen to their bodies. We don’t want them to be sedentary, and we want them to go out and continue living their lives. But I do warn them that the fatigue is pretty much common to all patients receiving radiation at various degrees, depending on the patient. I just tell them to do what they feel like doing, and then when they’re tired to rest, and if they find themselves having a nap in the afternoon, that’s okay.” TS 13:51
“What I find with these patients in particular is that a lot of times, their first symptoms related to any type of cancer are CNS symptoms from brain metastasis. Our patients with lung cancer or melanoma—they come in through the emergency room for altered mental status or seizures or something like that. They find a mass in their brain, and then they find a mass on their lung, or they find masses everywhere. Typically, they want to treat the brain masses first before they start them on any kind of systemic treatment. And so, they’ll come to us, and they’re in shock. Everything’s happened very quickly. They haven’t had a chance to really catch their breath. They’re overwhelmed. And so I try to make sure they understand that everyone that they see here is part of their team and is with them through this journey and they’re not alone.” TS 25:36
“A couple of years ago, ONS put out an email asking for people to volunteer to do a delineation study about the feasibility of doing a radiation oncology certified nursing exam. And I, just on a whim, responded to that email. It’s not something I’ve ever done before, and thinking that I would not be put on the team. … And I thought, ‘I don’t have enough experience, I don’t know what I’m doing, and they won’t choose me.’ And lo and behold, they put me on this role delineation study. … I have met so many incredible nurses with all kinds of experience. I’ve learned so much. It has opened up a lot of things for me and it’s been really exciting, so all I can do is say take advantage of those opportunities when they come. Don’t think that you don’t know enough, because you know more than you think you do.” TS 32:38
