Retrospective - Patients who are diagnosed with HER2-positive unresectable or mBC and have received at least 1 LOT in the advanced setting will be included. Approximately a total of 570-830 patients will be enrolled in the study.


Other interventions: None (Observational study)
The data on different types of treatment received by the patients, socio-demographics, and clinico-pathological characteristics and healthcare resource utilisation will be extracted from patients' medical records (both alive and deceased).

Eligibility
Key inclusion criteria
* Adult female or male patients =18 years old or 'adults' according to the age of majority as defined by the local regulations
* Patient or next of kin/legal representative willing and able to provide written informed consent according to the local regulations unless a waiver is granted by the local IRB/IEC/EC
* Patients' medical records showing a diagnosis of HER2-positive unresectable or mBC (can be either de novo advanced disease, progression or recurrence of previous early-stage HER2-positive BC) since the available date of T-DM1 (Kadcyla) through reimbursement or patient access programme as a valid local treatment option or 01 January 2017, whichever is earlier and with the availability of at least 12 months of follow-up data (from the date of diagnosis of unresectable or mBC) in the medical records at the participating site, unless patient died within the first 12 months of diagnosis
* Patients completing at least 1 LOT for HER2-positive unresectable or mBC
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Patients with HER2-negative unresectable or mBC at index diagnosis
* Patients with a change in HER2 status from positive to negative at the progression from early-stage to advanced-stage disease (ie, shown on a repeat biopsy at diagnosis of advanced-stage disease) will be excluded (patients who change from HER2-positive to negative on repeat biopsy during treatment for advanced-stage disease may be included)
* Patients with concomitant cancer at the time of diagnosis of HER2-positive unresectable or mBC except for the non-metastatic non-melanoma skin cancers, or in situ, or benign neoplasms; a cancer is considered concomitant if it occurs within 5 years of HER2-positive breast cancer diagnosis
* Patients who at the time of data collection for this study are participating or have participated in an interventional study that remains blinded

Summary
Brief summary
This multicountry, multicenter, retrospective, non-interventional study involving patients diagnosed with HER2-positive unresectable or metastatic breast cancer mBC will be conducted to understand the demographic and clinico-pathological profile of the patients, diagnostic practices for human epidermal growth factor receptor 2 (HER2) status, current treatment landscape and sequencing of therapies, associated burden of toxicities with all lines of treatment (LOTs), and survival outcomes in the real-world setting.
