This episode, number 29, focuses on Advanced Larynx T4a and the Unpreservable. Building upon Episode 28's discussion of organ preservation, we explore instances where such preservation is not the optimal course of action. Specifically, we examine how to identify patients for whom maintaining the larynx is either impractical or detrimental. Given the natural inclination to offer preservation, this episode aims to equip listeners with the knowledge to counsel patients appropriately, whether advocating for preservation when suitable or recommending upfront laryngectomy when it is the more beneficial pathway. By the conclusion of this episode, listeners will possess a framework for recognizing the "unpreservable" patient and understanding the limitations of current landmark trials when applied to bulky T4a disease.
