Lack of prognostic value of human epidermal growth factor-like receptor 2 status in inflammatory breast cancer (IBC): a meta-analysis

Asian Pac J Cancer Prev. 2014;15(22):9615-9. doi: 10.7314/apjcp.2014.15.22.9615.

Abstract

Inflammatory breast cancer (IBC) is a rare, aggressive form of breast cancer which is more likely to be her-2/ neu amplified. While the her-2/neu status has been utilised to predict prognosis, the published data are inconsistent. The present meta-analysis was conducted to determine whether the her-2/neu status predicts outcomes. Papers were selected from the PubMed database based on defined inclusion and exclusion criteria. Parameters such as total patients, follow-up time and outcome statistics (i.e. overall survival (OS), relapse-free survival (RFS) were collected. The analysis included 6 studies with 2,838 IBC patients. The summary hazards ratio (HR) estimating the association of OS with HER-2-positive disease was 0.96 (95% confidence interval (95%CI: 0.85-1.10)), with similar findings for RFS (HR=0.81, 95%CI: 0.61-1.09). No obvious statistical heterogeneity was detected. This meta-analysis suggests that HER-2-positive status is not an independent adverse prognostic factor for survival among IBC patient cases.
