Literature was identified and organized into categories then synthesized to form conclusions and identify knowledge gaps. Results: 96 records were identified after searching the literature and 69 records were subsequently reviewed. Conclusion: There is conflicting evidence regarding the utility of proposed biomarkers in predicting sensitivity of endometrial cancer to PARP inhibitor treatment. Current in vitro and in vivo studies suggest that PARP inhibitors may be effective in the treatment of certain subsets of endometrial cancer, but further research is warranted.
