What Are Tyrosine Kinase Inhibitors (TKIs)? Episode 37.

The Cracking Cancer Podcast

Show Notes

In this essential episode, host Dr. Kyle Concannon and co-host Samantha Murrell break down the science, promise, and limitations of Tyrosine Kinase Inhibitors (TKIs)—a class of highly effective, usually pill-form, targeted therapy. Dr. Concannon explains that TKIs are molecular snipers, designed to attack the root cause of cancer by blocking the signaling from a mutated protein (kinase) that causes cells to divide uncontrollably. They clarify the process from DNA blueprint to protein addiction, explaining why these targeted therapies are often more elegant and have fewer side effects than traditional chemotherapy.

The discussion also tackles the billion-dollar question of resistance. Dr. Concannon outlines three primary ways tumors evade TKIs: on-target resistance (a new mutation in the same protein), upregulation of other kinases (the tumor activates a second signaling pathway), and lineage change (the tumor stops relying on the oncogene altogether). Samantha shares her experience, confirming that while TKIs are not without side effects (like fatigue and potential for diarrhea), they represent a massive leap forward in treatment, offering hope for longer, higher-quality survival.

Key Takeaways:

In this episode of Cracking Cancer, host Dr. Kyle Concannon reunites with patient advocate Samantha Murrell and science communicator Dr. Rob Swanda to tackle some of the most persistent, widespread myths and misconceptions in oncology. The team explores the emotional and practical realities of navigating a cancer diagnosis, addressing online health claims, and clearing up common misunderstandings about treatments, genetics, and screening. Dr. Kyle and Samantha break down why pathology and diagnostic scans are not always straightforward, how "Stage IV" and "terminal" are often conflated, and why modern palliative chemotherapy looks vastly different from treatments 30 years ago. They also address dangerous online misinformation—such as the claim that biopsies or mammograms spread cancer, or that alternative therapies alone can cure metastatic disease. Finally, the panel emphasizes the critical role of open communication with your care team, particularly regarding potential interactions between targeted therapies and over-the-counter supplements.

In this episode of Cracking Cancer, host Dr. Kyle Concannon is joined by breast surgical oncologist Dr. Monique Gary (Dr. Mo) and Stage IV metastatic breast cancer advocate Lindsay Campbell. The panel unpacks the complex and often overwhelming world of breast cancer surgery, moving step-by-step from the initial consultation through the operating room experience to post-operative recovery. Lindsay shares her personal surgical path—navigating the emotional frustration of an 11-week scheduling delay due to tumor growth and operating room availability, which forced a pivot from a planned double mastectomy with DIEP flap reconstruction to an immediate lumpectomy. Dr. Mo demystifies surgical decision-making, explaining how tumor grade, genetic mutations (such as BRCA1/2), and hormone/HER2 status shape surgical choices. The panel also covers practical OR preparations—such as nerve blocks, pre-medication for nausea, surgical drain management, and handling "time toxicity"—offering actionable insights for patients preparing for their own surgical journeys.

In this episode of Cracking Cancer, host Dr. Kyle Concannon is joined by breast radiologist Dr. Deepa Sheth and Stage IV metastatic breast cancer advocate Lindsay Campbell. Lindsay shares her personal story of being diagnosed at age 38 after facing nearly a year of medical delays. Despite noticing visible skin dimpling and localized pain, she was repeatedly turned away because she was under the traditional screening age of 40 and lacked a felt mass due to deep chest-wall tumor placement. It was only after her father was diagnosed with breast cancer and identified as BRCA-positive that she was able to secure a diagnostic workup. Dr. Sheth and Lindsay break down the mechanics of screening versus diagnostic imaging, explaining how 2D/3D mammography, targeted ultrasound, and breast MRI function together. Dr. Sheth highlights the critical importance of free risk-assessment tools—such as the Tyrer-Cuzick model—which can identify high-risk individuals (>20% lifetime risk) who qualify for screening starting as early as age 30. The panel also tackles the federal mandate surrounding dense breast tissue, insurance coverage nuances, and why patients must trust their intuition when advocating for timely care.

In this episode of Cracking Cancer, host Dr. Kyle Concannon sits down in person with science communicator Rob Swanda, PhD, to tackle one of the most persistent and anxiety-inducing topics in oncology: Does sugar feed cancer? Rob and Kyle break down the biochemistry behind how the body processes carbohydrates, deconstruct online misconceptions, and address the real-world harm caused when cancer patients starve themselves of vital nutrition out of fear. Rob explains the Warburg Effect—a phenomenon where cancer cells preferentially use glucose via fast, anaerobic glycolysis to generate rapid cellular energy—and clarifies why cell culture findings in a Petri dish do not translate to human metabolism. Dr. Kyle discusses human glucose homeostasis, highlighting how the liver and muscles maintain steady blood sugar through gluconeogenesis and glycogen breakdown regardless of dietary intake. The hosts issue a stark warning against extreme restrictions that lead to cancer cachexia (muscle and weight wasting) and explain why, for patients without uncontrolled diabetes, enjoying food and maintaining caloric intake is far more vital than cutting out sugars.

In this episode of Cracking Cancer, science communicator Rob Swanda, PhD, is joined by glioblastoma researcher Dr. Julio Sanchez, a postdoctoral fellow at UCLA. Julio pulls back the curtain on early-stage cancer research, shedding light on the quiet, rigorous, and often high-failure world of preclinical science that takes place long before a new drug ever reaches a clinical trial. Julio details the transition from in vitro cell line work to complex in vivo mouse models, explaining why glioblastoma remains one of the most notoriously aggressive and difficult-to-treat brain cancers. He highlights his lab's recent publication in Cancer Research, which introduced next-generation, CRISPR-engineered mouse models that far better mirror human glioblastoma pathology and the tumor immune microenvironment compared to traditional cell lines developed in the 1970s. The pair also explore the rise of therapeutic mRNA vaccines and organoid platforms, and discuss why the scientific method is fundamentally a mindset built on resilience, critical thinking, and iterative problem-solving.
