"Overall survival & quality of life superiority in modern phase Ill oncology trials." Phase Ill onc RCTs are commonly called "positive." But this is usually based on alternative endpoint improvement. Gains in either OS or QOL are uncommon, & exceedingly rare in combo. #ASCO25
Just 2 incoming @MayoRadOnc faculty enjoying the views & company at the @JAMAOnc reception. #ASCO25

Broad-based genomic testing (beyond focused biomarker testing alone) for patients with advanced NSCLC led to ⬆️ targeted agent use and subsequently ⬆️ PFS & OS. @TrishaSantosMD #ASCO25



Adverse financial events prior to a cancer diagnosis lead to worse survival. Neat analysis of a linkage of cancer database with consumer data! #ASCO25 @DrRobinYabroff
