The ONS Podcast

  “One powerful, overlooked aspect of colorectal cancer survivorship is the emotional and identity transformation that our survivors undergo—and really how little space is given in the clinical arena for that. No one really talks about this ‘invisible recovery.’ Facing mortality can lead to prolonged changes is values, relationships, and life goals. And these experiences aren’t captured in lab results or imaging scans, but they really shape how survivors live, love, and heal and continue with their lives,” ONS member Kris Mathey, DNP, APRN-CNP, AOCNP®, gastrointestinal...

The ONS Podcast

“All of these TKIs [tyrosine kinase inhibitors] inhibit BCR-ABL1 in some way, shape, or form. When BCR-ABL1 is mutated, it has uncontrolled tyrosine kinase activity, leading to rapid cell proliferation. When we then inhibit that BCR-ABL1 that’s been mutated, we disrupt this abnormal signaling pathway that drives CML [chronic myeloid leukemia] cell proliferation and survival, ultimately leading to decreased cancer cell growth, increased apoptosis or cell death, and potentially inducing a disease remission,” Samantha Maples, PharmD, BCOP, clinical pharmacy specialist supervisor for...

“She’s triple negative and has a very, very aggressive tumor. Instead of going on spring break that year, she sat in our chemo room and got chemo. Her friends from college are good to try to keep her involved and try to surround her and encourage her, but they’re right now in very, very different spots in their lives. She’s fighting for her life; her friends are fighting for the grade they get in a class—and that’s different,” ONS member Kristi Orbaugh, MSN, NP, AOCN®, AOCNP®, nurse practitioner at Community Hospital North Cancer Center in Indianapolis, IN, told Jaime Weimer,...

“Policies help make sure that we’re giving patients the right education and discharge instructions. Radiation doesn’t end when the syringe is empty. Patients go home with potential radioactive exposure. They need to know how to protect their families, what precautions to take, and what healthcare providers can do if something goes wrong—like a spill, extravasation, or even a pregnant staff member who’s involved in the care. This isn’t just a documentation exercise. It’s about making sure every part of the system speaks the same language when it comes to safety, handling, and...

The ONS Podcast

“At least some of the answer to these issues of compassion fatigue and burnout have to do making our practice environments the very, very best they can be so that nurses and other clinicians can really connect and care for patients in the ways that they want to be able to do that—and the patients need them to be able to do. I think there’s a lot that is here already and will be coming, and I feel pretty optimistic about it,” ONS member Anne Gross, PhD, RN, NEA-BC, FAAN, senior vice president for patient care services and chief nursing officer at Dana-Farber Cancer Institute in...

“We’re really using these in many, many types of malignancies. But you can see this class of drug, these monoclonal antibodies, the small molecule inhibitors, being used in colorectal cancer, ovarian cancer, renal cell carcinoma, brain cancers, hepatocellular, non-small cell lung cancer, gynecologic malignancies, so lots of different types of cancers where we’re seeing these drugs used,” Danielle Roman, PharmD, BCOP, manager of clinical pharmacy services at the Allegheny Health Network Cancer Institute in Pittsburgh, PA, told Jaime Weimer, MSN, RN, AGCNS-BS, AOCNS®, manager of...

“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...

“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...

“The proteasome itself, it really helps us unfold or get rid of misfolded proteins or degradations of different cells. We used to have garbage disposals in our sinks, and we used to put food product in there. If your garbage disposal is clogged, then everything backs up. So that’s kind of what’s really going on in the cell itself, is that I’m building up these unnecessary proteins that we should be getting rid of, and it actually causes apoptosis or cell death,” ONS member Daniel Verina, DNP, RN, ACNP-BC, nurse practitioner for the multiple myeloma program at Mount Sinai Medical...

“We want to make sure that nurses, have opportunities both in our local communities as well as international communities, to engage in courageous dialog with others who may think or look different than we do and whose culture or language may also be different. The difference is what brings us together and allows us to have more of this tapestry of what we are about—ensuring that we advance health for all and that we are able to move forward together,” ONS member Ashley Leak-Bryant, PhD, RN, OCN®, professor at University of North Carolina (UNC) at Chapel Hill, told Darcy Burbage, DNP,...

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
