All three PE samples revealed γH2AX‐positivity in tumor cells, but only in samples from patients PL‐TUE #01 (no HRD) and PL‐TUE #02 (no HRD) we also detect RAD51‐positivity in tumor cells showing signs of DNA damage (RAD51+/γH2AX+) while residing in S/G2‐phase (RAD51+/γH2AX+ x CyclinA+). Here, RAD51 is linked to neoplasm.
