This observational study will characterize retrospectively patients with HER2-positive metastatic or locally advanced breast cancer who had received treatment with Herceptin (trastuzumab) in 1st line and who were without progression for at least three years. Patients will be followed prospectively for one year.

Further study details as provided by Hoffmann-La Roche:

Primary Outcome Measures:
  • Tumor Hormone Receptor Status of Participants Without Progression [ Time Frame: Up to 3 years ]
    The clinical and tumor characteristics including HER2 and Hormone Receptor (HR) status of metastatic breast cancer participants are analysed which are important factors which impact on Progression Free Survival.

  • Percentage of Participants With Prevalence of Bone Metastases Without Progression for at Least 3 Years After the Beginning of 1st Line Herceptin Treatment [ Time Frame: Up to 3 years ]
    Bone metastasis occurs when cancer cells spread from their original site to a bone. Percentage of participants with prevalence of bone metastases without progression were reported

Secondary Outcome Measures:
  • Progression-free Survival [ Time Frame: Up to 12 years ]
    The Progression-free survival (PFS) was defined as the time between the treatment start date (date of first trastuzumab infusion during the metastatic period) and the date of the first progressive disease or death from any cause. The method of assessment of disease progression was not outlined within the protocol, this was completed by each investigator in line with routine practice.

  • Time to Progression [ Time Frame: Up to 12 years ]
    The Time to progression (TTP) was defined as the time between the treatment start date (date of the first trastuzumab infusion during the metastatic period) and the date of the first progressive disease.

  • Overall Survival [ Time Frame: Up to 12 years ]
    The overall survival (OS) was defined as the time between the treatment start date (date of the first trastuzumab infusion during the metastatic period) and the death from any cause.

  • Dosage Schedule of Herceptin Treatment [ Time Frame: Up to 12 years ]
    Participants who received trastuzumab are reported in the below table. The regimen of trastuzumab in first line treatment is presented as in frequency 1 infusion (inf) per week (W) and dose per infusion as mg/kg.

  • Number of Participants With Antineoplastic Treatment in Combination With Trastuzumab and After Discontinuation of Trastuzumab Treatment [ Time Frame: Up to 12 years ]
    Antineoplastic treatment given in combination with and after discontinuation (Aft. Dis) of herceptin treatment included chemotherapy and hormonotherapy.

  • Number of Participants With Any Adverse Events and Serious Adverse Events [ Time Frame: Up to 1 year ]
    An adverse event (AE) was defined as any untoward medical occurrence that occurred during the course of the trial after study treatment had started. An adverse event was therefore any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug. A Serious Adverse Event (SAE) is any untoward medical occurrence that at any dose results in death, are life threatening, requires hospitalization or prolongation of hospitalization or results in disability/incapacity, and congenital anomaly/birth defect. The data was reported for prospective period.

  • The Duration of Treatment of Trastuzumab [ Time Frame: Up to 1 Year ]
    Total treatment duration and duration of the first line of treatment is reported.
