Updates and Insights on HER2 in Breast Cancer in Sohag Governorate (HER2)

August 10, 2026 updated by: Rana Amgad Anwar, Sohag University

Updates and Insights on Human Epidermal Growth Factor Receptor 2 (HER2) in Breast Cancer in Sohag Governorate

  • To evaluate HER2 expression in breast carcinoma with emphasizing HER2-ultralow, and HER2-low, HER2 equivocal tumors.
  • To correlate the results of HER2 with clinico-pathological prognostic parameters; examples tumor grade, Ki-67 proliferation index, nodal status, tumor size, lympho-vascular invasion, and perineural invasion, tumor infiltrating lymphocytes
  • To access interobserval agreement in HER2 score interpretation

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

HER2 status is no longer simply classified as a positive or negative. It is now evaluated on a score from 0 to 3+, where score 3+ indicates HER2-positive disease because it shows strong, complete circumferential membranous staining. In the HER2-negative spectrum, score 1+ and score 2+ without gene amplification are classified as HER2-low, while score 0 involves both HER2-null cases with no membrane staining and HER2-ultralow cases with faint or weak incomplete membranous staining in ≤10%, of tumor cells. In addition, ISH can be used to determine HER2 gene amplification status. The emergence of HER2-low and also HER2-ultralow concepts has challenged the traditional binary framework and increased the need for collective reporting. As a result, careful interpretation of delicate staining patterns, reproducible scoring and appropriate use of complementary testing methods are now central to accurate HER2 classification in both primary and metastatic breast cancer.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

The study population includes female patients with histopathologically confirmed breast cancer diagnosed at Sohag Oncology center during the study period (2025-2026). Archived formalin-fixed paraffin-embedded tissue blocks and corresponding pathology records will be retrospectively reviewed to evaluate HER2 status. Only cases meeting the eligibility criteria will be included.

Description

Inclusion Criteria:

  • Breast cancer cases diagnosed during 2025 and 2026.
  • Cases with available HER2 immunohistochemical results.
  • Cases with sufficient tissue material for evaluation.
  • Cases with complete clinical and follow-up data.
  • Cases that were accessible for pathologic review

Exclusion Criteria:

  • Cases with insufficient, destroyed, necrotic, or unavailable tissue blocks.
  • Cases with incomplete clinical information.
  • Cases lacking adequate immunohistochemical assessment.
  • Cases outside the study period

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Breast cancer female patients

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
September 1, 2026

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
