[VIRTUAL] Blood tests to predict one- to two-year survival of patients with difficult cancers. () - Apr 29, 2021 - Abstract #ASCO2021ASCO_4315; P2 Ts warrant development: validation with GFLIO and other therapy and other cancers; to improve Ts, models for eligibility and geriatric criteria; to identify false -/+ trials; and personalize trials to correct UnF Ts . FTs, with GFLIO, can change prognosis and practice for > 50% of pts now advised “against” any therapy due to a clinical estimate of “less than 6 -10 mos to live.”

[VIRTUAL] Genomic profiles of BRAF inhibitor resistance mechanisms in metastatic colorectal cancer. () - Apr 29, 2021 - Abstract #ASCO2021ASCO_4092; We analyzed next-generation sequencing results in 520 cancer-associated genes for 22 patients who had BRAF V600E mutant mCRC in order to characterize genomic predictors of treatment outcome and track the acquired resistance (AR) mechanisms during the vemurafenib/dabrafenib/encorafenib treatment in combination with cetuximab +/- trametinib . Our study illustrated the landscape of genetic alterations in patients with BRAF V600E mutant mCRC upon BRAF inhibitor treatment, which could be critical to predict responses to BRAF inhibitors and guide personalized clinical decision-making after disease progression.

[VIRTUAL] Global BRAF testing practices in metastatic colorectal cancer (mCRC). () - Apr 29, 2021 - Abstract #ASCO2021ASCO_4088; BRAF testing has global variability, impacting treatment decisions . Increased awareness and routine testing may lead to informed decisions regarding targeted therapies, such as encorafenib + cetuximab (where approved), in patients with BRAF V600E-mutant mCRC.

[VIRTUAL] Rarity of acquired mutations (MTs) after first-line therapy with anti-EGFR therapy (EGFRi). () - Apr 28, 2021 - Abstract #ASCO2021ASCO_2340; While selective pressure appears to increase the frequency of acquired MTs in the 3L setting, preexisting subclonal MTs do not appear to be the dominant source of acquired MTs at progression, implying that there may also be a transient mutational process driving resistance rather than expansion of preexisting clones . These findings have significant implications for ongoing and planned EGFRi rechallenge studies.
