简要总结

About 30% of breast cancers have higher than normal levels of a cellular marker called HER2. The amount of HER2 is often measured in breast tissue. A higher level of this marker usually indicates a more aggressive type of breast cancer. Cytokeratin is a second cellular marker found in breast cancer cells. Detection of Circulating cytokeratin in the blood could indicate the presence of cancer. The Pathology Department of the Tom Baker Cancer Center is doing this study to see if measuring the levels of circulating HER2 and cytokeratin, through blood testing has clinical significance for patients with breast cancer.

详细描述

  • Single Variate analysis will be performed to correlate variables such as tumour size, grade, stage, ER status, PR status and biopsy HER2 status with soluble HER2 levels.
  • Soluble HER2 levels will be analyzed as both a continuous and categorized variable.
  • The analysis will attempt to discern the relationship between soluble HER2 levels, HER2 positive circulating epithelial cell level and treatment response.
  • This will provide evidence of the effect various treatments have on HER2 levels. HER2 levels both in patients treated with Herceptin and those on other treatment protocols, will be related to clinical disease measures such as time to progression, time to failure, duration of response and duration of survival.
  • An initial model of the relationship between these factors and soluble HER2 as a marker will be established from the data.
