🚀 FDA approves Cemiplimab (Libtayo) — the first ever adjuvant immunotherapy for high-risk cutaneous squamous cell carcinoma (CSCC). In the phase 3 C-POST trial, Libtayo reduced recurrence risk by 68% (HR 0.32; p < 0.0001) after surgery + RT. A new milestone in adjuvant

Precision beyond age: the Trans-RESPECT study redefines HER2⁺ care for older women. In this prospective–retrospective analysis of the RESPECT trial, HER2DX—a 27-gene assay by Reveal Genomics—proved independently prognostic in women aged 70–80 with early-stage HER2⁺ breast

A fascinating new analysis in JAMA Network Open (Nov 2025) highlights a paradox many clinicians recognize but rarely discuss openly: PARP inhibitors dramatically improve PFS… yet OS differences remain blurred. Why? Because in nearly all major trials, crossover allows placebo
