Solvent Effects on Relative Stability of Meridine and Its Tautomer: MO Calculations

INTRODUCTION: Podany et al. examined associations between Area Deprivation Index (ADI) and tumor genomics, PI3K inhibitor use, and survival in 1,127 patients with metastatic breast cancer. While their multi-institutional, genomically annotated dataset is a valuable contribution, several methodological issues warrant scrutiny. METHODS: We critically reviewed the study's statistical approach, focusing on multiple-comparison handling, potential confounding from ctDNA shedding variability, and the reliability of subgroup survival estimates. RESULTS: Key findings (TP53, AKT1, overall survival, PI3Ki-use disparity, and Black patient survival disadvantage) relied on borderline p-values from uncorrected multiple comparisons across 19 supplementary tables. Lower visceral, nodal, and soft-tissue metastasis rates in high-deprivation patients suggest reduced ctDNA shedding, which could confound reported mutation-frequency differences, particularly for AKT1. The AKT1 subgroup hazard ratio (6.27) derived from roughly five events, far below recommended events-per-variable thresholds, raising concerns about estimate stability. CONCLUSION: Addressing multiplicity correction, ctDNA shedding assessment, and transparent event-count reporting would strengthen confidence in the study's conclusions and better inform future prospective research.
