A Tetra-Panel of Serum Circulating miRNAs for the Diagnosis of the Four Most Prevalent Tumor Types

2020

The purpose of this study is to clinically validate a series of circulating miRNAs that distinguish between the 4 most prevalent tumor types (lung cancer (LC)

Detection and characterization of tumor hypoxia using pO2 histography.

2007

Data from 125 studies describing the pretreatment oxygenation status as measured in the clinical setting using the computerized Eppendorf pO2 histography system have been compiled in this article. Tumor oxygenation is heterogeneous and severely compromised as compared to normal tissue. Hypoxia results from inadequate perfusion and diffusion within tumors and from a reduced O2 transport capacity in anemic patients. The development of tumor hypoxia is independent of a series of relevant tumor characteristics (e.g., clinical size, stage, histology, and grade) and various patient demographics. Overall median pO2 in cancers of the uterine cervix, head and neck, and breast is 10 mm Hg with the ov…

A randomized trial comparing tamoxifen therapy vs. tamoxifen prophylaxis in bicalutamide-induced gynecomastia.

2012

BACKGROUND: Tamoxifen (TAM) has been shown to be active against the bicalutamide-induced breast events (BEs) gynecomastia, and breast pain in patients with prostate cancer (PC). Optimal doses and schedules are not yet established. Debate still exists about whether prophylaxis with TAM is more effective than treatment of BEs when diagnosed. The results of a randomized study comparing TAM prophylaxis vs. TAM therapy are presented. METHODS: One hundred seventy-six patients with prostate cancer (PC) who were candidates for bicalutamide monotherapy were randomized to receive TAM 20 mg daily orally within 1 month from the onset of BEs (arm A) vs. TAM 10 mg daily starting simultaneously with bical…

Vitamin D in cancer chemoprevention

2015

Context: There is increasing evidence that Vitamin D (Vit D) and its metabolites, besides their well-known calcium-related functions, may also exert antiproliferative, pro-differentiating, and immune modulatory effects on tumor cells in vitro and may also delay tumor growth in vivo. Objective: The aim of this review is to provide fresh insight into the most recent advances on the role of Vit D and its analogues as chemopreventive drugs in cancer therapy. Methods: A systematic review of experimental and clinical studies on Vit D and cancer was undertaken by using the major electronic health database including ISI Web of Science, Medline, PubMed, Scopus and Google Scholar. Results and conclus…

Molecular target therapy for bone metastasis : starting a new era with denosumab, a RANKL inhibitor

2014

Abstract: Introduction: The skeleton is generally the primary, and sometimes the only, site of metastasis in patients with advanced solid tumors. Bone metastases are the most frequent cause of cancer-related pain and the origin of severe morbidity in patients. Among the treatment options available for the prevention of skeletal-related events (SREs) associated with bone metastasis, zoledronic acid, an antiresorptive treatment from the group of bisphosphonates, is currently the standard of care in this setting. Areas covered: Zoledronic acid, together with denosumab (a monoclonal antibody against the receptor activator of nuclear factor kappa B ligand), is the most frequent approach for the …

Prognostic Significance of Interferon-γ and Its Signaling Pathway in Early Breast Cancer Depends on the Molecular Subtypes

2020

Interferons are crucial for adaptive immunity and play an important role in the immune landscape of breast cancer. Using microarray-based gene expression analysis, we examined the subtype-specific prognostic significance of interferon-&gamma

The EndoPredict Gene-Expression Assay in Clinical Practice - Performance and Impact on Clinical Decisions

2013

The validated EndoPredict assay is a novel tool to predict the risk of metastases of patients with estrogen receptor positive, HER2 negative breast cancer treated with endocrine therapy alone. It has been designed to integrate genomic and clinical information and includes clinico-pathological factors such as tumor size and nodal status. The test is feasible in a decentral setting in molecular pathology laboratories. In this project, we investigated the performance of this test in clinical practice, and performed a retrospective evaluation of its impact on treatment decisions in breast cancer. During one year, EndoPredict assays from 167 patients could be successfully performed. For retrospe…

Immunoglobulin Kappa C Predicts Overall Survival in Node-Negative Breast Cancer

2012

Background: Biomarkers of the immune system are currently not used as prognostic factors in breast cancer. We analyzedthe association of the B cell/plasma cell marker immunoglobulin kappa C (IGKC) and survival of untreated node-negative breast cancer patients.Material and Methods: IGKC expression was evaluated by immunostaining in a cohort of 335 node-negative breast cancer patients with a median follow-up of 152 months. The prognostic significance of IGKC for disease-free survival (DFS) and breast cancer-specific overall survival (OS) was evaluated with Kaplan-Meier survival analysis as well as univariate and multivariate Cox analysis adjusted for age at diagnosis, pT stage, histological g…

New methods to improve the safety assessment of cryopreserved ovarian tissue for fertility preservation in breast cancer patients

2015

Objective To develop a novel molecular panel of markers to detect breast cancer (BC) disseminated malignant cells in ovarian tissue, and to improve the safety of ovarian tissue transplantation. Design Experimental study. Setting University hospital. Patient(s) Ten ovarian biopsies from healthy patients, 13 biopsies with diagnosed BC metastasis, and 4 biopsies from primary BC tumor for designing a diagnostic panel of BC cell contamination; 60 ovarian biopsies from BC patients undergoing fertility preservation for validating the panel. Animal(s) Female nude mice. Intervention(s) A novel panel for BC malignant cell detection by reverse-transcription polymerase chain reaction (RT-PCR), inmmunoh…
