Once amplified cases were segregated from other cases of gene gain, non-amplified gene increases ( TOP1 /CEN-2≥1.5 and TOP1/CEN-20<2.0) showed a trend towards shorter TTR (univariate HR: 1.57, p = 0.07).
Once amplified cases were segregated from other cases of gene gain, non-amplified gene increases ( TOP1 /CEN-2≥1.5 and TOP1/CEN-20<2.0) showed a trend towards shorter TTR (univariate HR: 1.57, p = 0.07).
Amplification of TOP1 was not significantly associated with OS or TTR, although approached significance for TTR in the multivariate analysis (HR: 0.50, 95% CI: 0.23–1.09, p = 0.08).
Amplification of the TOP1 gene, representing a situation where CEN-20 is not involved in gene gain, exhibited a weak trend towards longer TTR when compared to the rest of the population, a finding which may be attributed to the low number of event in this particular subgroup.
