Cancer Frontiers (Video) is a feed of talks by UCSF specialists, and its recent episodes stay with one disease: prostate cancer. The format is the academic talk. A speaker presents from slides, credits colleagues whose slides they borrowed, and hands off to the next presenter, and in some sessions a moderator introduces each one. The titles show the range at a glance: 'Active Surveillance for Early-Stage Prostate Cancer', 'More on Localized Prostate Cancer', 'Overview: PSA Recurrent Prostate Cancer', 'Treatment of Advanced Prostate Cancer', 'Systemic Therapy Approaches for Advanced Prostate Cancer' and 'Prostate Cancer Survivorship: Urinary and Sexual Wellness'. Together they run from the first decision after diagnosis to life after treatment. Several speakers begin by pinning down their terms. Stephen Sane, a radiation oncologist, sets out how a PSA recurrence is defined after surgery or radiation, which factors raise its likelihood, and a tailored approach to clinical and imaging evaluation. Another talk defines advanced prostate cancer as any setting where local therapy can no longer control the disease, and notes that sensitive functional imaging such as PSMA PET has changed how that line is drawn. On early-stage disease, one speaker calls prostate cancer a spectrum with no hard demarcations between grades. In that talk, treatment decisions rest on three things: the cancer itself, the age and health of the patient, and the patient's own preferences. The same talk argues that active surveillance is safe, citing long-term outcomes from UCSF. A session moderated by Krista Chiu, an assistant professor of urology, covers localized treatment, starting with Peter Carroll, a urology professor and former chair of the department. That session covers prostatectomy, the goal of an undetectable PSA within weeks of surgery, and focal therapy with HIFU, which a speaker says depends on careful patient selection. The advanced-disease talks look ahead. One session describes advanced prostate cancer as something now managed more like a chronic disease. It then moves to theranostics, which pairs a diagnostic agent with a therapeutic one, and to immunotherapy, presented by a speaker from the cancer immunotherapy program. The speakers are open about uncertainty: the role of hormone therapy alongside radiation is called an open question, and for one agent still in phase three studies they say plainly that they are waiting on the results. There are lighter moments too, as when one speaker recalls giving a colleague a hard time for calling post-operative radiation straightforward. The survivorship talk speaks plainly about continence, describing a curve of improvement through the first year that eventually plateaus, with treatment options if leakage remains bothersome. Across all of it, the value is watching specialists reason: imaging, life expectancy and a patient's goals weighed together, often in consensus with colleagues from other specialties, before a plan is settled.
