The findings of the current study indicated that young patients with TNBC had an enhanced cell cycle, which may have helped to explain their inferior short-term survival, whereas the homologous recombination deficiency and enriched pathogenic germline variants observed among young patients with TNBC suggested the need for genetic counseling and testing, as well as the potential use of DNA damage agents and poly(adenosine diphosphate ribose) polymerase (PARP) inhibitors. Molecular characteristics of elderly patients with TNBC, although suggesting less response to chemotherapy, provided a rationale for the routine detection of actionable somatic mutations.
