ObjectiveTo summarize progression of growth factor receptor (GFR) signaling pathway in endocrineresistant breast cancer. Method Literatures about mechanisms of GFR signaling pathway in the development of endocrineresistant breast cancer were reviewed. ResultsThe crosstalk between GFR and estrogen receptor (ER) signaling pathway had been reported to be involved in the development of endocrine-resistant breast cancer. Interrupting this signaling pathway could overcome endocrine therapy resistance. Many clinical trails had shown that the utilizing endocrine therapy combined with GFR inhibitors could obviously increase the survival rate of patients with breast cancer. ConclusionSeveral agents targeting GFR signaling pathways show a great potential for treatment of patients with breast cancer.
ObjectiveTo evaluate the efficacy and toxicity of gemcitabine, paclitaxel plus cisplatin (GTP) chemotherapy for advanced urothelial carcinoma in China. MethodsTen patients with advanced urothelial carcinoma who underwent GTP chemotherapy regimens were collected from February to July 2014 in our hospital. According to solid tumor curative effect evaluation standard 1.1, we evaluated the clinical effcacy and collected the adverse reactions. ResultsTen patients with advanced urothelial carcinoma accepted first-line chemotherapy using GTP chemotherapy regimens. There was 1 case of complete remission, 4 cases of partial response, 3 stable cases, and 2 progressive cases. Adverse reactions of degree Ⅲ were mainly of hematology toxicity, including 5 cases of leukocytes and neutrophils reduction, and 1 case of anemia. The remaining adverse reactions included gastrointestinal reaction, hair loss, and abnormal renal function. ConclusionGTP chemotherapy regimen is a promising treatment for advanced urothelial carcinoma.
