    Excerpt:
    In the MSKCC cohort involving 185 patients with gastrointestinal adenocarcinoma, the mutation of any member involved in BAF complex (ARID1A, ARID1B, SMARCA4, SMARCB1, and SMARCD1) was significantly associated with prolonged OS of ICI treatment (HR 0.53, 95%CI 0.31-0.90, P=0.019)...
