BACKGROUND Inflammation may play an important role in cancer progression, and a high neutrophil-to-lymphocyte ratio (NLR) has been reported to be a poor prognostic indicator in several malignancies. Here we quantify the prognostic impact of this biomarker and assess its consistency in solid tumors. METHODS A systematic review of electronic databases was(More)
BACKGROUND The androgen receptor (AR) is expressed frequently in breast cancer, but its prognostic significance is unclear. Preclinical data suggest that expression of AR may modify clinical outcomes in early breast cancer with improved prognosis in estrogen receptor (ER)-positive disease and poorer prognosis in ER-negative disease. METHODS A systematic(More)
BACKGROUND Abiraterone acetate (abiraterone) prolongs overall survival (OS) in patients with metastatic castration-resistant prostate cancer (mCRPC). This study's objective was to retrospectively identify factors associated with prostate-specific antigen (PSA) response to abiraterone and validate them in an independent cohort. We hypothesized that the(More)
BACKGROUND The neutrophil-to-lymphocyte ratio (NLR), a marker of inflammation, has been reported to be a poor prognostic indicator in prostate cancer. Here we explore the use of the NLR to establish a simple prognostic score for men with metastatic castration-resistant prostate cancer (mCRPC) treated with docetaxel. METHODS In the training cohort, the NLR(More)
Background:An elevated neutrophil-to-lymphocyte ratio (NLR) is associated with poor outcome in various tumours. Its prognostic utility in patients with urothelial carcinoma of the bladder (UCB) undergoing radical cystectomy (RC) is yet to be fully elucidated.Methods:A cohort of patients undergoing RC for UCB in a tertiary referral centre between 1992 and(More)
BACKGROUND Inflammation influences cancer development and progression. An elevated platelet to lymphocyte ratio (PLR), a marker of inflammation, has been linked to poor prognosis in several malignancies. Here, we quantify the prognostic impact of this biomarker. METHODS A systematic review of databases was conducted to identify publications exploring the(More)
BACKGROUND The human epidermal growth factor receptor 3 (HER3) is an ErbB/HER family member that dimerizes with other ErbB receptors such as HER2. Numerous agents against HER3 are in clinical development despite variable data for the prognostic impact of HER3 expression. Here we report a meta-analysis of the association of HER3 expression and survival in(More)
BACKGROUND The neutrophil-lymphocyte ratio (NLR), proposed as an indicator of cancer-related inflammation, has known prognostic value in prostate cancer. We examine its association with survival (OS) and response in patients treated with second-line chemotherapy. METHODS We analysed patients with metastatic castration-resistant prostate cancer (mCRPC)(More)
BACKGROUND The neutrophil-to-lymphocyte ratio (NLR), a marker of host inflammation, has been associated with poor outcome in several solid tumors. Here, we investigated associations of the derived NLR (dNLR) and duration of initial androgen deprivation therapy (ADT) with survival of men with metastatic castration-resistant prostate cancer (mCRPC) receiving(More)
BACKGROUND The phosphatase and tensin homolog (PTEN) tumor suppressor gene is deregulated in many advanced prostate cancers, leading to activation of the phosphatidylinositol 3-kinase (PI3K)-Akt-mammalian target of rapamycin (mTOR) pathway and thus increased cell survival. OBJECTIVE To evaluate everolimus, an inhibitor of mTOR, in patients with metastatic(More)
