  • Improving treatment of inflammatory breast cancer

    Improving treatment of inflammatory breast cancer
    2022/02/27
    Inflammatory breast cancer (IBC) is rare and accounts for only 1% to 5% of all breast cancers, but it is considered an aggressive cancer because it grows quickly and is more likely to come back after treatment than other types of breast cancer. It causes symptoms of breast inflammation like swelling and redness, which is caused by cancer cells blocking lymph vessels in the skin causing the breast to look "inflamed." Gayathri R. Devi, PhD, is a two-time American Cancer Society grantee who recently received a Mission Boost Grant to “boost” her inflammatory breast cancer research and move it closer to patients. Dr. Devi joined the podcast to talk about risk factors for IBC, how it’s different from other breast cancer types, and recent advances in her lab with promising clinical implications. Dr. Devi is Program Director for the Duke Consortium for Inflammatory Breast Cancer, Associate Professor of Surgery and Pathology at Duke School of Medicine, and the Director of the Duke North Carolina Central University bridge office as part of the Duke School of Medicine Clinical and Translational Sciences Institute. 3:18 – The symptoms and signs of inflammatory breast cancer (IBC) 6:34 – How inflammatory breast cancer differs from other, more common breast cancers 9:36 – Risk factors for inflammatory breast cancer 14:22 –Instead of a single tumor mass, IBC patients have small groups of tumor cells called emboli found in the breast, skin and lymph nodes around the breast tissue. What are emboli? How do they form? 16:00 – Why do emboli form in this way? 18:51 – What makes these emboli resistant to treatment and able to spread? 21:43 – On her ACS-funded research, which focuses on the environment in which the IBC emboli form, in the breast. Why is the breast environment so important? 28:35 – Adaptive stress response 31:15 – “I’ll give you an example here and talk a little about our research findings that are clinically relevant.” 38:25 – How do we target inflammatory breast cancer therapeutically? 40:47 – The 3M approach: Models, Mechanisms, and Measures 45:30 – If she could wave a magic anti-IBC wand, where would we be in 5 years? 48:27 – The impact that ACS funding has had on this area of research 49:54 – “Another very important distinction about ACS…” 51:47 – How inflammatory breast cancer recently affected her family

  • “Holding Hope for Cancer Patients with Serious Illness”

    “Holding Hope for Cancer Patients with Serious Illness”
    2021/12/03
    When a cancer patient has a serious diagnosis, clinicians and families can struggle with how patients experience hope. Three distinguished palliative care physicians and researchers joined the podcast for a conversation about their recent paper in JAMA titled, “Holding Hope for Patients with Serious Illness” (https://jamanetwork.com/journals/jama/article-abstract/2784454). Drs. Abby Rosenberg, Robert Arnold, and Yael Schenker shared their own experiences treating seriously ill patients and talked about how we can navigate the tension between appreciating the potential therapeutic benefit of hope and being concerned about perceived unrealistic hopes: “Rather than being concerned that hope is either so fragile that it can be lost, or so powerful that it can overwhelm decision making, clinicians should remember that hope is protective, if not necessary, for managing serious illness. Holding complex, flexible, and diverse hopes enables patients to believe in the unlikely while simultaneously accepting the inevitable. The role of clinicians is to support both.” Abby Rosenberg, MD, MS, MA, is a pediatric oncologist and palliative care physician and researcher at the University of Washington, where she directs the pediatrics component of the Cambia Palliative Care Center, and Seattle Children’s Research Institute, where she directs the Palliative Care and Resilience Lab. She has an American Cancer Society Research Scholar Grant to study “Resilience Outcomes Among Adolescents and Young Adults with Advanced Cancer.” Robert M. Arnold, MD, is a palliative care physician, Distinguished Professor of Medicine, and Chief of the Palliative Care Section at the University of Pittsburgh. He previously served as a member of the American Cancer Society’s palliative care peer review committee. Yael Schenker, MD, MAS, is a palliative care physician, Professor of Medicine, and Director of the Palliative Research Center (PaRC) at the University of Pittsburgh. She is a past recipient of American Cancer Society research funding, which supported her study of “Primary Palliative Care for Patients with Advanced Hematologic Malignancies.” 3:27 - The therapeutic benefit of hope and why it’s helpful to patients and caregivers 5:12 – Why clinicians sometimes feel the need to “correct” a patient’s hope 8:56 – How physicians can address the tension of appreciating the potential therapeutic value of hope but being concerned about perceived unrealistic hopes 10:50 – On how physicians can help patients diversify and increase their hopes 6:24 – How they became interested in this topic and decided to explore this topic in a broader way 17:35 – Advice they would share with someone in medical school who might someday treat patients with a poor prognosis 19:03 – A message for caregivers of a patient with a terminal illness

  • What causes small cell lung cancer growth and resistance?

    What causes small cell lung cancer growth and resistance?
    2021/11/05
    Lung cancer is the leading cause of cancer death among both men and women in the United States and worldwide. Small cell lung cancer comprises 15-17% of lung cancer cases, and it is the most aggressive subtype of lung cancer, growing rapidly and spreading to other organs quickly. Luke Hoeppner, PhD, received American Cancer Society funding to test whether therapeutically targeting a specific molecular pathway inhibits small cell lung cancer growth. Dr. Hoeppner’s lab was the first to report that activation of this particular pathway, called dopamine signaling, inhibits other forms of lung cancer growth. By therapeutically altering the dopamine signaling pathway, he hopes to inhibit small cell lung cancer progression and drug resistance, facilitating further advancement to new treatments. For more information about lung cancer, visit https://www.cancer.org/cancer/lung-cancer.html. Luke Hoeppner, PhD, is Assistant Professor and leader of the Cancer Biology research section at The Hormel Institute, University of Minnesota. 5:09 – What is small cell lung cancer? What vital statistics about it should we know? 5:57 –What is the standard therapy for small cell lung cancer patients? 8:13 – Why is it so hard to treat? 10:04 – “Another way to put it is…” 13:59 – Why drug resistance is such an important area of research for small cell lung cancer 15:42 – “We’re trying to focus on understanding what in particular small cell lung cancer cells are doing to evade chemotherapy, and is there a combination treatment that we could add to chemotherapy that would prevent (resistance)?” 16:18 – On his lab’s novel approach to combatting resistance 24:17 – What are the therapeutic implications? 25:05 – Why he’s optimistic about this line of research 26:31 – On how American Cancer Society funding has impacted his research 27:18 – A message he’d like to share with cancer patients, survivors, and caregivers

  • Improving our understanding of risk factors for breast cancer sub-types

    Improving our understanding of risk factors for breast cancer sub-types
    2021/10/08
    According to American Cancer Society researchers, in the United States in 2021, there will be an estimated 281,550 new cases of invasive breast cancer diagnosed in women.* Finding breast cancer early and getting state-of-the-art cancer treatment are the most important strategies to prevent deaths from breast cancer. Breast cancer that’s found early, when it’s small and has not spread, is easier to treat successfully. Getting regular screening tests is the most reliable way to find breast cancer early. The American Cancer Society has screening guidelines for women at average risk of breast cancer, and for those at high risk for breast cancer: https://www.cancer.org/cancer/breast-cancer/screening-tests-and-early-detection/american-cancer-society-recommendations-for-the-early-detection-of-breast-cancer.html. Two breast cancer researchers joined the podcast to discuss screening for the early detection of breast cancer. Anne Marie McCarthy, PhD is a cancer epidemiologist and assistant professor at the University of Pennsylvania’s School of Medicine. She is the recipient of an American Cancer Society Research Scholar Grant to fund her research into “A Precision Medicine Approach to Breast Cancer Early Detection.” Lauren Teras, PhD, is a senior scientific director of epidemiology research in the Population Science team at the American Cancer Society. 7:43 – Important things to know about breast cancer risk 9:55 – Why mammography is recommended for all women - “Any woman that has breasts should think about screening for breast cancer with mammography on a regular basis” 12:50 – But mammography screening isn’t necessarily enough for all women 18:26 – On the challenges of mammography screening and aggressive cancers 23:21 – On the association of breast density with cancer risk 26:48 – Women who could benefit from more intensive screening 29:46 – On being the best advocate for yourself (What do recommendations and high-risk categories mean for an individual?) 34:45 – A message for breast cancer patients, survivors, and caregivers 35:56 – The impact of American Cancer Society funding on Dr. McCarthy’s research * https://www.cancer.org/content/dam/cancer-org/research/cancer-facts-and-statistics/annual-cancer-facts-and-figures/2021/cancer-facts-and-figures-2021.pdf
