The field of precision oncology has witnessed several advances that stimulated the development of new clinical trial designs and the emergence of real-world data (RWD) as an important resource for evidence generation in healthcare decision-making. Here, we highlight our experience with an innovative approach to a set of Adaptive, Universal Principles for Real-world Observational Studies (AUPROS). To demonstrate the utility of these principles, we used a mixed-methods approach to assess three studies that follow AUPROS at Princess Margaret Cancer Centre: (1) Molecular Epidemiology of ThorAcic Lesions (METAL), (2) Translational Head And NecK Study (THANKS), and (3) CAnadian CAncers With Rare Molecular Alterations (CARMA; NCT04151342). We performed resource assessments, stakeholder-directed surveys and discussions, analysis of funding, research output, collaborations, and a Strengths-Weaknesses-Opportunities-Threats (SWOT) analysis. Based on these analyses, AUPROS is an approach that is applicable to a wide range of observational study designs. The universality of AUPROS allows for multi-purpose analyses of various RWD, and the adaptive nature creates opportunities for multi-source funding and collaborations. Following AUPROS can offer cost and logistical benefits and may lead to increased research productivity. Several challenges were identified pertinent to ethics approvals, sustainability, complex coordination, and data quality that require local adaptation of these principles., Competing Interests: Competing interests: PM is an employee at Takeda Canada Inc.

Close monitoring after diagnosis of patients with stage I-III non-small cell lung cancer (NSCLC) may result in fitter patients with lower disease burden at the time of metastatic recurrence or progression compared to patients diagnosed initially as stage IV (de novo). We compared the presentation, treatments, and outcomes of patients with KRAS G12C -mutated NSCLC with de novo versus recurrent stage IV disease. Of 109 patients, 94% had a smoking history. When compared to patients with KRAS G12C -mutated NSCLC who developed stage IV disease at recurrence (n = 38), de novo stage IV patients (n = 71) had worse ECOG performance status (p = 0.007), greater numbers of extra-thoracic metastatic sites (p = 0.001), and were less likely to receive 2nd/3rd line systemic therapy (p = 0.05, p = 0.002) or targeted therapy (p = 0.001). De novo metastatic patients had shorter overall survival than metastatic patients at recurrence (9.1 versus 24.2 months; adjusted-hazard-ratio=1.94 (95% CI: 1.14-3.28; p = 0.01)). There is a critical need for well-tolerated targeted therapies in the first-line setting for metastatic patients with de novo, high-burden, stage IV KRAS G12C -mutated NSCLCs., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.
