In ER-negative/HER2-negative tumors, the MSH2, MSH6, and FAN1 (previously MTMR15) genes were associated with pathological complete response and residual invasive cancer in taxane/anthracycline-treated patients.
Simulations comparing normal to BRCA1-mutant breast tissue demonstrated rates of invasive cancer development similar to published epidemiologic data with respect to both cumulative incidence over time and estrogen-receptor status.
In the distal colon, methylation of the age-related loci decreased as the stage of neoplasia increased (patients with no neoplasia or with adenoma < or =9 mm versus patients with advanced adenoma or with invasive cancer: ESR1-PMR median, 21.0 versus 15.7; P = .015; MYOD1-PMR median, 5.35 versus 3.80; P = .0037, respectively).
