“The five-year relative survival rate for localized, or cancer that is confined to the colon or the rectum, is 91% for colon cancer and 90% for rectal cancer. Distant, metastasized to other organs—the five-year survival rate is 13% for colon and 18% for rectal cancer. So that really shows you the huge difference in screening and where screening can come in and make better outcomes,” 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, told Jaime Weimer, MSN,...

“Just remember that these patients, these are human beings who had lung cancer. It’s a scary disease. And we don’t want to just say, ‘Oh, well, that’s a horrible disease. They probably won’t do well.’ These patients are living longer. Our treatments are better. And so no matter who they are, they have every chance of surviving long term for this,” ONS member Beth Sandy, MSN, CRNP, thoracic medical oncology nurse practitioner at the Abramson Cancer Center at the University of Pennsylvania in Philadelphia, told Jaime Weimer, MSN, RN, AGCNS-BS, AOCNS®, manager of oncology...

“That’s what metastatic breast cancer looks like now—patients can live an extended period of time. And sometimes I think we forget to cheer for stable disease. I tell patients they can live with weeds in their garden; they just can’t let the weeds take over their garden. And today we don’t have a cure. We live in a rapidly changing time in oncology, and so there’s just so much hope right now that we can offer patients,” ONS member Kristi Orbaugh, MSN, NP, AOCN®, AOCNP®, nurse practitioner at Community Hospital North Cancer Center in Indianapolis, IN, told Jaime Weimer, MSN,...

Episode 367: Pharmacology 101: PARP Inhibitors “We know that in cells that are proliferating very quickly, including cancer cells, single-strand DNA breaks are very common. When that happens, these breaks are often repaired by the PARP enzyme, and the cells can continue their replication process. If we block PARP, that repair cannot happen. So in blocking that, these single-strand breaks then lead to double-strand breaks, which ultimately is leading to cell apoptosis,” Danielle Roman, PharmD, BCOP, manager of clinical pharmacy services at the Allegheny Health Network Cancer Institute in...

“[My mom] would always be very inspirational whenever I would see her studying so long. And when she finally got to be a nurse, I always admired her vocation and compassion with her patients. She would always go above and beyond for all of her patients. I also got inspired a lot by my brother, as well, just seeing how passionate he was for caring for his patients for the families as well, and helping them deal with the any grief or loss that they were experiencing, Carolina Rios, MSN, RN, CPhT, told Valerie Burger, RN, MA, MS, OCN®, CPN, member of the ONS 50th anniversary planning...

“From a radiation standpoint, the biggest thing we’re looking at is the treatment site, the dosage, and the way the radiation has been delivered. There are different ways that we can focus radiation using methods such as intensity-modulated radiotherapy, volumetric modulated arc therapy, flattening radiation beams, and proton beam therapy to try to help minimize radiation exposure to healthy tissues to minimize patient risk for secondary cancers,” ONS member Andrea Matsumoto, DNP, AGACNP-BC, AOCNP®, radiation oncology nurse practitioner at Henry Ford Health in Detroit, MI, told Jaime...

“Everyone will probably say this, but it is so true. Do not cram the night before the exam. The most important thing the night before the exam is to get a good night’s sleep. You might be so nervous. You’re like, ‘I can get any new information that matters right before the exam,’ but you can’t. Any information that you know you will have gotten in the time that you spent studying already. Really, you have to trust yourself,” Talia Lapidus, BSN, RN, professional staff nurse in the neonatal intensive care unit at UPMC in Pittsburgh, PA, told Jaime Weimer, MSN, RN, AGCNS-BS,...

“A lot of other disease sites, they have some targeted therapies, they have some immunotherapies [IO]. In lung cancer, we have it all. We have chemo. We have IO. We have targeted therapies. We have bispecific T-cell engagers. We have orals, IVs. I think it’s just so important now that, particularly for lung cancer, you have to be well versed on all of these,” ONS member Beth Sandy, MSN, CRNP, thoracic medical oncology nurse practitioner at the Abramson Cancer Center at the University of Pennsylvania in Philadelphia, told Jaime Weimer, MSN, RN, AGCNS-BS, AOCNS®, manager of oncology...

“The signaling and that binding of the MET and the HGF help, in a downstream way, lead to cell proliferation, cell motility, survival, angiogenesis, and also invasion—so all of those key cancer hallmarks. And because of it being on an epithelial cell, it’s a really good marker because it’s found in many, many different types of cancers, so it makes it what we call kind of a nice actionable mutation,” ONS member Marianne Davies, DNP, ACNP, AOCNP®, FAAN, senior oncology nurse practitioner at Yale Comprehensive Cancer Center in New Haven, CT, told Jaime Weimer, MSN, RN, AGCNS-BS,...

“We spent time today discussing all the ways that owners can have a positive impact on career growth, whether you’re a bedside nurse or just in teaching, research, hospital leadership. More than career growth, I see ONS as kind of a barrier to burnout and a catalyst for professional self-care. I think that no matter what aspect of oncology care you’re involved in, it is a difficult and complex specialty. And I think with that can come a lot of challenges and tough days, and ONS brings a sense of community to that and, specifically, a community that is pushing cancer care forward,”...
info_outline“A lot of the efforts have been made to improve the patient experience for these treatments, as they can be given for years at a time. For example, when leuprolide debuted way back in 1985, it was a daily injection. But four years later, they developed the monthly depo formulation. Now we have formulations that are approved for administration once only every three, four, and even six months,” Andrew Ruplin, PharmD, clinical oncology pharmacist at 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 the luteinizing hormone–releasing hormone (LHRH) antagonist and agonist drug classes.

Highlights From This Episode
“Between all of these agonists and antagonists, there’s a broad spectrum of applications, including hormone-positive breast cancer, androgen-deprivation therapy for prostate cancer, uterine cancer, and then other non-cancer uses like uterine fibroids, and assisted reproduction fertility treatments, and other things too.” TS 3:24
“In the education of my female patients, I basically use the analogy that it is functionally inducing menopause in that person, so there can be changes to mood and cognition, energy level fatigue, body morphology, and shifts in fat distribution metabolism, which can unfortunately increase the risk of cardiovascular disease. One that almost everyone’s familiar with is hot flashes, but also changes to bone mineral density, libido and physically to atrophy and dryness of vaginal mucosa, which can make sex for our patients more difficult as well.” TS 10:33
“A concept that’s familiar to all professionals in the care of prostate cancer is that because LHRH agonists cause an initial increase in testosterone, which can, in essence, feed the cancer, some patients can experience worsening symptoms of their cancer, such as difficulty voiding their bladder pain, or even vertebral collapse or spinal cord compression when bone metastases are present. This is a really serious issue that should be considered ahead of starting an agonist in these patients.” TS 12:39
“I don’t think we’ll see any dramatic changes in treating breast cancer, since the role of these agents is a lot more limited and simply really exist to suppress estrogen and premenopausal patients. But as a referral center that routinely sees patients with breast cancer and their 40s and 30s and even their 20s, it’s crucial to consider these agents in their role for not only actively treating certain types of breast cancer, but also in preserving fertility for patients who desire to have children and they are receiving gonadotoxic chemotherapy.” TS 25:32
