Ovarian cancer is one of the highest mortality rate of gynecologic malignant tumors. Chemotherapy can improve the survival rate of the traditional ovary. In recent years, PARP [poly(ADP-ribose)polymerase]inhibitors in breast cancer susceptibility gene (breast cancer susceptibility gene, BRCA) mutations in patients with ovarian cancer can significantly improve the disease-free survival, may change the prognosis of patients with ovarian cancer. This part of PARP [poly(ADP-ribose)polymerase] inhibitors, inhibiting the repairment of DNA damage in tumor cell, causing DNA damage accumulation, eventually killing tumor cells.In breast cancer susceptibility gene 1 (breast cancer susceptibility gene1, BRCA1)/BRCA2 mutation patients with ovarian cancer, PARP inhibitors and BRCA mutation of the synthetic lethal effect provides a new direction for the development of anti-cancer drugs. Now, many highly selective and sensitive PARP inhibitors have been developed and applied in clinical trials.Although PARP inhibitor monotherapy can produce a therapeutic effect in BRCA mutation in patients with ovarian cancer, but the clinical application is still used in combination with other chemotherapy or radiotherapy. This review is focused on the recent progress in clinical trials of PARP inhibitors in combination with common chemotherapeutic agents.
