No patients showed a recurrence with a median follow-up of 20 months.All patients tried to get pregnant spontaneously and during all follow-up period, without resorting to any medical therapy.MMR-deficient (dMMR) cases, defined by lack of MMR protein expression detected by IHC analysis of tumor tissue, showed resistance to treatment more commonly than MMR-proficient (pMMR) cases [2 (33.3%) vs. 10 (15.9%)], with a RR of 2.1 (95%CI: 0.6–7.5) but with no statistical significance (p = 0.2508). Here, MRC1 is linked to neoplasm.
