Outcome Measures

Primary Outcomes (3)

  • Progression-free survival

    Obtain a survival curve using the Kaplan-Meir method in all cohorts, and compare the survival rates between cohort A vs cohort B in total patients, BRCA WT and mutation patients using the log-rank test. Multivariate survival analysis will be performed using Cox's proportional hazard model.

    3 years

  • Safety analysis

    The fraction that adverse events occurred, the fraction that dose modification occurred, the fraction that dose delay occurred, and the fraction that treatment discontinuation occurred were calculated, respectively. The comparison of the fractions between groups will be done by the Chi-square test or the Fisher exact test. Comparison of means between groups will be done by Student t test or Mann-Whitney U test.

    3 years

  • Overall survival analysis

    Obtain a survival curve using the Kaplan-Meir method in all cohorts, and compare the survival rates between cohort A vs cohort B in total patients, BRCA WT and mutation patients using the log-rank test. Multivariate survival analysis is performed using Cox's proportional hazard model.

Study Population

Considering the nature of retrospective study, sample size cannot be calculated based on reference. The investigators have a plan to collect the patient data as much as possible from multi-centers.

You may qualify if:

  • Patients were diagnosed with all histologic type of epithelial ovarian cancer
  • Observation cohort (Cohort A): All patients who did not receive any kind of maintenance therapy for primary epithelial ovarian cancer from Dec 2019 to Dec 2022
  • Treatment cohort: Epithelial ovarian cancer patients who treated with niraparib as maintenance treatment in any line from Dec 2019 to Dec 2022
  • Cohort B: All patients who received or who are receiving niraparib maintenance therapy for primary epithelial ovarian cancer in 1st line setting
  • Cohort C: All patients who received or who are receiving niraparib maintenance therapy for recurrent epithelial ovarian cancer in 2nd or 3rd line setting
  • Cohort D: All patients who received or who are receiving salvage niraparib therapy for recurrent epithelial ovarian cancer in 4th line or more line setting

You may not qualify if:

  • Borderline ovarian tumor
  • Malignant ovarian germ cell tumor
  • Malignant sex-cord stroma tumor
  • Other malignancy within 5 years of diagnosis of epithelial ovarian cancer excluding carcinoma in situ of uterine cervix, endometrium, bladder, stomach, papillary thyroid cancer, and non-melanoma skin cancer
