Gender | All |
Age group | 18 Years and older |
Eligibility | Inclusion Criteria: 1. Male or female patients who have at least 18 years of age at enrollment. 2. Patients with initial diagnosis of early BC or locally advanced BC or de novo mBC between the 1st of January 2005 and the 31st of December 2021 3. Pathologically documented BC for: - HER2 receptor expression with a validated assay according to American Society of Clinical Oncology - College of American Pathologists (ASCO/CAP) recommendations at the time of diagnosis. HER2 receptor expression can be: o HER2-positive expression: defined as immunohistochemistry (IHC) 3+ or concurrent IHC 2+ with in situ hybridization (ISH) positive or HER2-low expression: defined as IHC 2+ with ISH-negative or IHC 1+ with ISH-negative or untested) or HER2-negative expression: defined as IHC: 0. - Estrogen receptor [ER]- and/or progesterone receptor [PgR] with a validated assay according to ASCO/CAP guidelines at the time of diagnosis during early and/or advanced setting. ER/PgR expression can be: positive: ER or PgR =1% or negative: ER and PgR <1% 4. Electronic Health Records (EHRs), with guaranteed data to meet requisites, about clinicopathological characteristics, type of surgery, treatment management, disease outcomes, and genomic profile. Centers that agree to participate must commit to include all subjects who meet the inclusion criteria, in order to reduce possible selection bias. Exclusion criteria: 1. Medical charts at Hospital that cannot guarantee reliable and congruent EHRs. 2. If sufficient data cannot be obtained from EHRs. |

---|---|---|---|---|
Primary | Prevalence of HER2 expression change between initial diagnosis versus any of the subsequent BC relapses | Change in HER2 expression between initial diagnosis of early BC or locally advanced BC or de novo mBC and any of subsequent BC relapses by IHC and/or ISH validated assays. | 180 months | |
Secondary | Prevalence of changes in HER2 expression among different lines of treatment | HER2 expression changes as assessed by IHC (0+, 1+, 2+, 3+) and/or ISH (positive or negative) validated assays among different lines of treatment in the advanced setting, and/or among different metastatic sites. | 180 months | |
Secondary | Description of the clinicopathological characteristics | Description of all the comprehensive clinicopathological characteristics (age at diagnosis, gender [male or female], baseline Eastern Cooperative Oncology Group [ECOG] performance status [0, 1, or 2], breast cancer pathological subtype at primary site, intrinsic subtype at primary and/or metastatic site by PAM50 test [including luminal A, luminal B, HER2-overexpressing, and basal-like], ER and PgR status [positive and/or negative] at primary and/or metastatic site, HER2 status by IHC and/or ISH testing [HER2-positive, HER2-low expressing, and HER2-negative status per ASCO-CAP guidelines] at primary and/or metastatic site, Ki67 at primary and/or metastatic site, endocrine resistance [primary or secondary]), metastatic sites (bone, brain, visceral involvement) nodal involvement, presence of measurable or evaluable disease per Response Evaluation Criteria In Solid Tumors (RECIST) in all patients enrolled. | 180 months | |
Secondary | Evaluation of the disease management | Description of disease management and treatment patterns in all patients enrolled for gaining contemporary insights into HER2-low expressing breast cancer treatment trends that may inform clinicians for future management plans. | 180 months | |
Secondary | Description of genomic profile | Identification of patients' genomic profile including DNA alterations and/or RNA expression of genes commonly disrupted in breast cancer, including driver, prognostic-related, and drug-response associated genes in tissue or liquid biopsies from all patients enrolled. | 180 months | |
Secondary | Efficacy (OS) | Overall survival (OS) is defined as the time from date of primary treatment initiation to date of death due to any cause. In the absence of confirmation of death, survival time will be censored to last date the participant was known to be alive. | 180 months | |
Secondary | Efficacy (ORR) | Objective response rate (ORR) is defined as the sum of complete response (CR) and partial response (PR) relative to the number of patients in the analysis set with measurable disease at baseline as per RECIST v.1.1. | 180 months | |
Secondary | Efficacy (CBR) | Clinical benefit rate (CBR) is defined as the proportion of participants with CR, PR or stable disease (SD) =24 weeks relative to the number of patients in the analysis set as per RECIST v.1.1. | 180 months | |
Secondary | Efficacy (PFS) | Progression-free survival (PFS) is defined as the period of time from treatment initiation to the first occurrence of disease progression or death from any cause, whichever occurs first, as determined locally by the investigator using RECIST v.1.1. | 180 months | |
Secondary | Efficacy (DoR) | Duration of response (DoR) is defined as the time from the first documentation of objective tumor response (CR or PR) to the first documentation of disease progression, death due to any cause or treatment discontinuation, whichever occurs first as per RECIST v.1.1. | 180 months |
