Advancing Biomarker-Driven Strategies in NSCLC: Exploring the Emerging Role of QCS and TROP2 NMR - Episode 11
Broader Implications and Future Impact of QCS and AI-Driven Digital Pathology in Precision Oncology
Panelists discuss the expanding potential of quantitative cell scoring (QCS) technology beyond TROP2, highlighting its ability to assess not only cell surface expression but also internalization critical for antibody-drug conjugate (ADC) efficacy. They also emphasize how artificial intelligence (AI)-driven pathology advancements promise to streamline lung cancer diagnostics, improve predictive accuracy, and reduce variability in biomarker testing, ultimately enabling more precise patient selection and better integration of complex biomarker data into clinical care.
The potential applications of QCS technology extend well beyond its current use with TROP2. This platform could revolutionize how ADCs are evaluated by not only measuring cell surface expression but also providing insight into internalization, which is an essential factor for ADC effectiveness. Current challenges include correlating expression levels with patient outcomes, but emerging evidence suggests that QCS could offer a more accurate and functional assessment of drug delivery at the cellular level. As more ADCs enter clinical trials, this technology holds promise for identifying the patients most likely to benefit, moving beyond unselected populations and improving clinical trial success.
Advances in AI integration within pathology are expected to dramatically impact lung cancer diagnostics over the next 5 to 10 years. Predictive algorithms are being developed that can identify mutations and triage patients for further testing even from unstained slides. This computational pathology approach could streamline workflows by rapidly highlighting patients with a high likelihood of specific biomarkers, allowing for targeted and timely testing. Moreover, AI-driven quantitative scoring methods can reduce the variability and subjectivity often seen with manual pathology assessments, leading to more consistent and objective results across different labs and clinical settings.
Despite progress, variability in biomarker testing remains a significant challenge, with discrepancies observed even among academic centers. Quantitative digital pathology promises to address these issues by standardizing scoring and reducing errors, ultimately improving diagnostic accuracy and patient care. The evolution toward more objective, reproducible pathology will support the integration of complex biomarker data into clinical decision-making, helping tailor treatments more precisely and ensuring emerging therapies reach the right patients at the right time.
