説明
Inclusion Criteria:
- Provision of signed, written and dated informed consent.
- Adult females (according to the age of majority/adulthood as defined by local regulations).
- Histologically or cytologically confirmed HER2-ve breast cancer with evidence of metastatic disease.
- Initiated treatment with 1st line systemic cytotoxic chemotherapy (not hormonal therapy) for metastatic breast cancer in the last 90 days and, at that time, are considered to have exhausted hormone therapy options (if HR+ve).
Exclusion Criteria:
- Previous enrolment in this study.
- Involvement in the planning and/or conduct of this study (applies to both AstraZeneca staff and/or staff at the study site).
- Current participation in a clinical study with an investigational oncology product.
- Previous PARPi therapy, including, but not limited to, participation in a previous clinical study that included PARPi therapy.
- Current commencement of PARPi treatment.

Observation
Human epidermal growth factor receptor 2 negative metastic breast cancer patients who have started 1st line systemic cytotoxic chemotheraphy and are considered to have exhausted hormone therapy options (if HR+ve), per investigator's opinion.
|
If unavailable from the patient medical records, gBRCA gene mutation status will be tested as aligned to local clinical practice using a blood sample obtained preferably during routine clinical practice.
(Note: Blood samples may be shipped to a central laboratory for testing and storage, based on local regulations for shipment of blood samples.)
Archival tumour specimen will be requested from all patients in the informed consent, but is not required for study enrolment (optional consent). Where sufficient archival tumour specimen is available and patients have consented to tumour specimen testing, FoundationOne Dx genomic profiling may take place as follows:
Patients who test positive for a gBRCA gene mutation, and/or sBRCA or other HRR gene mutations (optional testing), will be followed prospectively for assessment of treatment patterns and associated clinical outcomes up to 30-months. - Patients who test negative for gBRCA gene mutations, sBRCA and other HRR gene mutations, no further data will be collected post baseline. Patients presenting other genomic alterations that are identified by the FoundationOne Dx genomic profile will not continue beyond baseline as part of this study. |

BRCA Mutational status (BRCA1 mutated and/or BRCA2 mutated or BRCA wild type).
時間枠:At one time point at inclusion in the study up to 12 months after the beginning of the study.
|
The prevalence of gBRCA gene mutations will be evaluated by calculating the proportion of patients that test positive for a gBRCA gene mutation (BRCA1 mutated and/or BRCA2 mutated).
|
At one time point at inclusion in the study up to 12 months after the beginning of the study.

|
Descriptive statistics for treatments administered by line of therapy from 1st line metastatic breast cancer.
時間枠:2.5 years (30 months) since the beginning of the study.
|
Treatment patterns will be described by line of therapy.
Treatment combinations, number of cycles per line, schedules, durations, and reason for discontinuation will be summarized descriptively.
|
2.5 years (30 months) since the beginning of the study.
|
|
Progression free survival by line of therapy
時間枠:2.5 years (30 months) since the beginning of the study.
|
Progression free survival (in months) for each line of treatment, defined as the time from the date of start of each line of treatment to the documented date of progression as determined by the investigator (radiologic or symptomatic), or death from any cause in the absence of progression.
|
2.5 years (30 months) since the beginning of the study.
|
|
Overall survival by line of therapy
時間枠:2.5 years (30 months) since the beginning of the study.
|
Overall survival (OS) defined as the time from the start date of first line chemotherapy in the metastatic setting until the date of death due to any cause, assessed up to 30 months.
In addition, OS since diagnosis of metastatic breast cancer and OS since the start of each subsequent therapy will be estimated.
|
2.5 years (30 months) since the beginning of the study.
