Summary

Dr. Jessica McAlpine, a surgeon-scientist at UBC and BC Cancer, presents a comprehensive overview of recent advances in endometrial cancer research and clinical care. She begins by acknowledging the traditional territories and the Women’s Health Research Institute. The talk covers the evolution from histomorphology-based classification to a molecular classification system, driven by the Cancer Genome Atlas (TCGA) in 2013, which identified four molecular subtypes: POLE ultramutated, mismatch repair deficient, copy number high (p53 abnormal), and copy number low (NSMP). The ProMiSE algorithm, developed by her team, provides a pragmatic clinical test using sequencing and immunohistochemistry. This classification improves diagnostic reproducibility, prognostic stratification, and guides treatment decisions, including targeted therapies and de-escalation. Recent work focuses on further stratifying the NSMP subgroup using estrogen receptor (ER) status, which is now incorporated into 2025 ASCO guidelines. Additionally, she discusses sub-stratification of mismatch repair deficient tumors based on MLH1 promoter methylation, which has prognostic and therapeutic implications. Finally, she presents promising AI-based approaches using convolutional neural networks on H&E slides to identify high-risk NSMP tumors, potentially applicable to biopsies for early triage. The talk emphasizes the importance of integrating molecular and AI tools to enhance precision and improve patient outcomes.

Critical Evaluation

Value of the Information & Strength of the Argument

The presentation provides high-value information by synthesizing recent research and clinical guidelines, offering actionable insights for clinicians and researchers. The argumentation is solid, grounded in published studies and clinical trial data, with clear explanations of the biological rationale behind molecular subtypes and their clinical implications. The speaker effectively demonstrates the limitations of traditional histology and the added value of molecular classification, supported by survival curves and examples of clinical impact. The discussion of ER stratification and AI applications is well-argued, with references to recent publications and ongoing work. The talk is persuasive and evidence-based, though it primarily reflects the speaker’s expert opinion and institutional experience.

Scientific Rigor, Source Quality, Title Accuracy

The scientific rigor is high, with references to landmark studies such as TCGA and the ProMiSE validation, as well as recent ASCO guidelines. The speaker clearly distinguishes between established knowledge and emerging research, and discloses financial support without conflict of interest. The title accurately reflects the content, which focuses on adding precision through molecular classification and AI. The presentation is well-structured and aligns with current evidence, though it does not provide a systematic review of all literature. The speaker’s expertise and the inclusion of recent data enhance credibility. No comments were provided for analysis.
