Extranodal Extension of Nodal Metastases Is a Poor Prognostic Indicator in Gastric Cancer: a Systematic Review and Meta-analysis.

2016

Introduction: The extranodal extension (ENE) of nodal metastases (the extension of neoplastic cells through the nodal capsule into the perinodal soft tissue) is a histological feature that has been considered a prognostic factor in several cancers, but the role in gastric cancer was not yet investigated. We aimed to investigate the prognostic role of ENE in patients affected by gastric cancer through a systematic review and meta-analysis. Material and Methods: Two independent authors searched major databases until 09/30/2015 to identify studies providing data on gastric cancer patients’ prognostic parameters and comparing patients with ENE (ENE+) vs intra-nodal extension (ENE−). The data we…

Association Between CYP2D6 Polymorphisms and Outcomes Among Women With Early Stage Breast Cancer Treated With Tamoxifen

2009

Context The growth inhibitory effect of tamoxifen, which is used for the treatment of hormone receptor–positive breast cancer, is mediated by its metabolites, 4-hydroxytamoxifen and endoxifen. The formation of active metabolites is catalyzed by the polymorphic cytochrome P450 2D6 (CYP2D6) enzyme. Objective To determine whether CYP2D6 variation is associated with clinical outcomes in women receiving adjuvant tamoxifen. Design, Setting, and Patients Retrospective analysis of German and US cohorts of patients treated with adjuvant tamoxifen for early stage breast cancer. The 1325 patients had diagnoses between 1986 and 2005 of stage I through III breast cancer and were mainly postmenopausal (9…

Detection methods predict differences in biology and survival in breast cancer patients

2012

Abstract Background The aim of this study was to measure the biological characteristics involved in tumorigenesis and the progression of breast cancer in symptomatic and screen-detected carcinomas to identify possible differences. Methods For this purpose, we evaluated clinical-pathological parameters and proliferative and apoptotic activities in a series of 130 symptomatic and 161 screen-detected tumors. Results After adjustment for the smaller size of the screen-detected carcinomas compared with symptomatic cancers, those detected in the screening program presented longer disease-free survival (RR = 0.43, CI = 0.19-0.96) and had high estrogen and progesterone receptor concentrations more …

Prognostic Impact of Immunoglobulin Kappa C in Breast Cancer Patients Treated with Adjuvant Chemotherapy.

2020

<b><i>Introduction:</i></b> Immunoglobulin κC (IGKC)-positive tumor-infiltrating plasma cells are associated with better prognosis in node-negative breast cancer patients without adjuvant systemic therapy. In the present study we evaluated the prognostic significance of IGKC in breast cancer patients treated with adjuvant chemotherapy ± tamoxifen. <b><i>Methods:</i></b> IGKC expression was immunohistochemically analyzed in 193 breast cancer patients who were treated with adjuvant chemotherapy, either with cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) or 5-fluorouracil, epirubicin, and cyclophosphamide (FEC) between 1993 and 2001 wit…

Elimination of Established Risk-Factors in Primary Central Nervous System Lymphoma - Impact of High-Dose Chemotherapy Followed by Autologous Stem-Cel…

2011

Abstract Abstract 3089 Introduction: High-dose chemotherapy (HDT) and autologous stem-cell transplantation (ASCT) demonstrated high efficacy in the treatment of newly-diagnosed primary CNS lymphoma (PCNSL) in eligible patients (pts). Prognosis of PCNSL is associated with several clinical and histopathological risk factors (RF). Early complete response (CR) during chemotherapy (CHT) was recently reported to be an additional independent prognostic factor in pts undergoing polychemotherapy without HDT+ASCT. In this analysis, we examined the extent to which known RF determined survival in pts who were treated with HDT-ASCT. We additionally investigated the impact of HDT-ASCT specific factors (e…

Prognostic factors for progression-free and overall survival in advanced biliary tract cancer

2015

BACKGROUND: Biliary tract cancer is an uncommon cancer with a poor outcome. We assembled data from the National Cancer Research Institute (UK) ABC-02 study and 10 international studies to determine prognostic outcome characteristics for patients with advanced disease.METHODS: Multivariable analyses of the final dataset from the ABC-02 study were carried out. All variables were simultaneously included in a Cox proportional hazards model, and backward elimination was used to produce the final model (using a significance level of 10%), in which the selected variables were associated independently with outcome. This score was validated externally by receiver operating curve (ROC) analysis using…

Comparison of genetic risk prediction models to improve prediction of coronary heart disease in two large cohorts of the MONICA/KORA study

2021

Abstract It is still unclear how genetic information, provided as single‐nucleotide polymorphisms (SNPs), can be most effectively integrated into risk prediction models for coronary heart disease (CHD) to add significant predictive value beyond clinical risk models. For the present study, a population‐based case‐cohort was used as a trainingset (451 incident cases, 1488 noncases) and an independent cohort as testset (160 incident cases, 2749 noncases). The following strategies to quantify genetic information were compared: A weighted genetic risk score including Metabochip SNPs associated with CHD in the literature (GRSMetabo); selection of the most predictive SNPs among these literature‐co…

Analysis of immunosuppressive factors produced by tumorspheres in NSCLC: Prognostic value of galectin-3 in adenocarcinoma

2019

Abstract Background Cancer stem cells (CSCs) are targets poorly recognized by the immune surveillance system given that they induce an immunosuppressive microenvironment. The aim of this work is to study the interactions between CSCs and the immune microenvironment in NSCLC. Methods Tumor cells from 8 resected NSCLC patients and 12 cell lines were established as tumorspheres enriched in CSCs and as monolayers. The gene expression of IL-4, IL-10, IL6, IL8 and LGALS-3 was analyzed by RTqPCR. Results were validated at a protein level by a sensitivity bead-based multiplex immunoassay using the Millipore kit for Luminex 100/200. The prognostic value of these factors in silico was determined in a…

Renal cell carcinoma (RCC) comprises a heterogenous group of tumors. Traditionally, papillary RCC (pRCC) is associated with a favorable outcome compared to clear cell RCC (ccRCC), while other series report equivalent or worse prognosis. In this paper we comparatively evaluate outcome of pRCC versus ccRCC in two large multi-institutional databases (cohort study), including distribution of pRCC subtypes 1 and 2. Retrospective data of 1,943 surgically treated pRCC patients from 17 European/ North American centers between 1984-2015 were compared to 5,600 ccRCC patients from a database comprising 11 European/ North American centers (1984-2011). Median follow-up was 64.6 months. Differences betwe…

PMS2: a potential prognostic protein marker in oral squamous cell carcinoma

2020

Background An increase in oral squamous cell carcinoma (OSCC) cases was observed despite the reduction in exposure to classic risk factors. Although the exact cause of this trend remains unknown, epigenetic factors could be contributing to an increased occurrence of these tumors. This study aims to assess the influence of PMS2 protein immunoexpression on the prognosis of patients with OSCC. Material and Methods This study comprised 76 cases of OSCC treated between 2011 and 2016. Immunohistochemical staining for PMS2 was performed. For evaluation, 10 fields per histological section were photographed at a 400x magnification and positively-stained cells were counted with Image J. Mann-Whitney …
