Brief summary

This single arm observational study will assess the duration and safety of treatment with trastuzumab in routine clinical practice in participants with early or metastatic HER2-positive breast cancer. Data will be collected from female participants treated with trastuzumab according to the Summary of Product Characteristics and local protocols. Duration of observation for each participant is from therapy initiation until permanent discontinuation for any cause.

MeasureTime frameDescription
Percentage of Participants Who Received Previous Neoadjuvant TherapyBaseline up to 5 yearsAs a neoadjuvant therapy, participants received chemotherapy alone, radiotherapy alone, hormonal therapy alone or combination of these therapies. Percentage of participants who received these therapies is reported.
Percentage of Participants Who Had Surgical Procedure for Breast CancerBaseline up to 5 yearsPercentage of participants who underwent different types of surgical procedures for breast cancer are reported. Different types of surgical procedures included: breast-conserving surgery; mastectomy; and other (any other surgical procedure except breast-conserving surgery and mastectomy).
Percentage of Participants Who Discontinued Trastuzumab Therapy According to Reasons for DiscontinuationBaseline up to 5 years
Progression Free SurvivalBaseline uo tp 5 yearsProgression free survival was defined as the time from first dose of trastuzumab to disease progression as assessed by treating physician. Due to observational nature of the study, there was no specific method of assessment used to define progressive disease. Progressive disease was confirmed by treating physician, based on his/her assessment according to local practice.
Percentage of Participants by the Site of First Disease ProgressionBaseline up to 5 years
Percentage of Participants Who Received Trastuzumab as Adjuvant Therapy of HER2 Positive Breast CancerBaseline up to 5 years
