microRNA of Human Epidermal Growth Factor Receptor 2 （HER2）Positive Patient Treated With Herceptin

October 12, 2016 updated by: Erwei Song, M.D., Ph.D., Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University

A Perspective Study of the Predictive Value of microRNA in Patients With HER2 Positive Advanced Stage Breast Cancer Who Were Treated With Herceptin

This projective observational study is planned to enroll more than 300 advanced breast cancer patients, who were proved as Her-2 positive using fluorescence in situ hybridization (FISH) and / or immunohistochemistry, and 100 healthy donors as control. Before treatment, the plasma microRNA will be collected and detected by microRNA extraction kit and quantitative polymerase chain reaction (qPCR), respectively. After analyzed their microRNA expression by microRNA predictive model, previously reported by our team, all of enrolled patients will be classified as "probable sensitive group" or "probable resistant group". Herceptin combined with other chemotherapy will be the backbone of salvage treatment and used for at least 3 months; the change of local masses and metastasis lesions after treatment will be documented to evaluate the response. Based on these results, investigator aim to construct a mathematical predictive model by analyzing the correlation of baseline microRNA expression level and the prognosis of patients. And a diagnosis microRNA kit will be planned and manufactured

Herceptin probable sensitive group
Plasma microRNAs will be collected using microRNA extraction kit according to manufacturer's instructions; and their expression levels are analyzed by quantitative polymerase chain reaction (qPCR).According to microRNAs - herceptin predictive model(reported by our team), the patients will be considered as Herceptin probable sensitive group
Drug: Capecitabine
Capecitabine will be administered orally at a dose of 2500mg/m2 daily for 3 months (Day 1 to 14 of a 21-day cycle)
Other Names:
  • Xeloda
Drug: Trastuzumab
patients will receive herceptin intravenous infusion at a dose of 6mg on day 1 of each cycle
