Detailní popis
The main objective is to evaluate the outcome of olaparib-based maintenance therapy by proportion of patients alive and progression free at 1 year (1-yr PFS rate) We hypothesize that olaparib monotherapy could be beneficial for tBRCAwt high-grade serous ovarian cancer (HGSOC) patients who are treated with platinum-based first-line chemotherapy.
The secondary objectives are to evaluate the outcomes of olaparib-based maintenance therapy by: 1) 2-yr PFS rate; 2) median PFS; 3) median Time to First Subsequent Therapy or death (mTFST) ; 4) post-progression treatment after first progression; 5) reason for olaparib dose adjustment, dose interruptions, and dose discontinuations; 6) Reason for use of concomitant therapy.
The exploratory objective is to evaluate the status quo of genetic testing, R0 resection and related outcomes.

Popis
Inclusion Criteria:
Patients are eligible to be included in the study only if they met all the following criteria:
- Female Patients must be ≥18 years old at diagnosis.
- Patients with newly diagnosed, histologically confirmed, advanced (FIGO stage III-IV) ovarian cancer, primary peritoneal cancer and / or fallopian-tube cancer and received olaparib from Aug 2018 up to Dec 2020 (the time range could be extended in order to recruit enough eligible subjects as required).
- Patients must have a tumor BRCA testing result which is tBRCAwt, defined as tumor BRCA wild type (patients without evidence of BRCA 1 and/or BRCA 2 deleterious or suspected deleterious mutations).
- Patients who have completed first-line platinum-based chemotherapy and were in clinical complete response (CR) or in partial response (PR).
- Patients who were still in CR or PR before receiving maintenance therapy.
- Patients who received at least one dose of olaparib tablets monotherapy as maintenance therapy within three months after platinum-based chemotherapy and without disease progression.
Exclusion Criteria:
Patients are excluded if any of the following factors were present:
- Patient with multiple primary cancers as reported in EMR.
- Concomitant any anti- cancer therapy (chemotherapy, immunotherapy, hormonal therapy (Hormone replacement therapy (HRT) is acceptable), radiotherapy, biological therapy or other novel agent) during Olaparib maintenance.
- Any previous treatment with PARP inhibitor.
- Patients with myelodysplastic syndrome/acute myeloid leukaemia or with features suggestive of MDS/AML.
- Patients with symptomatic uncontrolled brain metastases.
- Any other concerns related to decreased efficacy and safety of maintenance therapy.

Olaparib mono-maintenance therapy group
Olaparib monotherapy in clinical practice and will be conducted in patients with tBRCAwt newly diagnosed high grade epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in response (complete response or partial response) to platinum-based chemotherapy following the standard of care from Aug 2018 up to Dec 2020 (the time range could be extended in order to recruit enough eligible subjects as required) at tertiary-referral university hospitals and main cancer centers in China.
|
Olaparib mono-maintenance therapy in patients with newly diagnosed, histologically confirmed, advanced (FIGO stage III-IV) ovarian cancer, primary peritoneal cancer and / or fallopian-tube cancer is defined as drug exposure.
At least one dose of olaparib tablets monotherapy as maintenance therapy will be required.
