Up to 50% of uveal melanomas (UM) metastasize to the liver within 10 years of diagnosis, and these almost always prove rapidly fatal. Since histopathological growth patterns (HGP) of liver metastases of the replacement and desmoplastic type, particularly from colon and breast carcinoma, may import valuable biological and prognostic information, we have studied HGP in a series of 41 UM liver metastases originating from 41 patients from the period 2006-2017. Twenty patients underwent enucleation while 21 had radiation therapy...

Poor clinical responses to checkpoint blockade with anti-CTLA-4 and anti-PD-1 antibodies in melanoma have recently been associated with acquired IFNγ resistance that protects tumor cells from the antiproliferative and pro-apoptotic cytokine activity. IFNγ-resistant melanoma cells very often lack functional expression of the IFNγ signaling pathway gene JAK2 due to gene deletions or inactivating gene mutations. Analyzing melanoma cell lines (n = 46, applying next-generation targeted sequencing and single nucleotide polymorphism arrays) as well as available genomic data sets from The Cancer Genome Atlas (TCGA) tumor tissue samples (cutaneous melanoma n = 367, lung squamous cell carcinoma n = 501, bladder urothelial carcinoma n = 408, breast invasive carcinoma n = 768, colorectal adenocarcinoma n = 257), we demonstrate that the frequent chromosomal losses of the tumor suppressor CDKN2A in melanoma and other tumor entities enhance the susceptibility to IFNγ resistance by concomitant deletion of the JAK2 gene (odds ratio = 223...

Background: Aromatase inhibitors improve disease-free survival compared with tamoxifen in postmenopausal women with hormone receptor-positive breast cancer. The Tamoxifen and Exemestane Adjuvant Multinational (TEAM) trial compared exemestane monotherapy with sequential therapy of tamoxifen followed by exemestane. The trial failed to show a statistically significant difference between treatment arms. A robust translational program was established to investigate predictive biomarkers. Methods: A tissue microarray was retrospectively constructed using a subset of patient tissues (n = 4631) from the TEAM trial (n = 9766)...

Background: Based on its mechanism of action, PARP inhibitor therapy is expected to benefit mainly tumor cases with homologous recombination deficiency (HRD). Therefore, identification of tumor types with increased HRD is important for the optimal use of this class of therapeutic agents. HRD levels can be estimated using various mutational signatures from next generation sequencing data and we used this approach to determine whether breast cancer brain metastases show altered levels of HRD scores relative to their corresponding primary tumor...

Nanodiamonds have demonstrated potential as powerful sensors in biomedicine, however, their translation into routine use requires a comprehensive understanding of their effect on the biological system being interrogated. Under normal fabrication processes, nanodiamonds are produced with a graphitic carbon shell, but are often oxidized in order to modify their surface chemistry for targeting to specific cellular compartments. Here, we assessed the biological impact of this purification process, considering cellular proliferation, uptake, and oxidative stress for graphitic and oxidized nanodiamond surfaces...

The three genes encoding small non‑coding microRNA (miR)34a, MIR34b and MIR34c act as tumor‑suppressor genes. Their aberrant expressions regulated by DNA methylation have been frequently found in various types of cancer. In the present study, the DNA promoter methylation profiles of the MIR34 gene family were analyzed using the methylation specific polymerase chain reaction in order to clarify their association with breast and lung cancer, non‑cancerous or normal adjacent tissues. The methylation frequency of MIR34a was significantly higher in breast cancer (49...

Recently, microRNA (miR)‑590‑5p has been shown to inhibit tumorigenesis in colorectal and breast cancer; however, its function in osteosarcoma (OS) requires further investigation. In the present study miR‑590‑5p expression was poorly expressed in OS samples and cell lines when compared with that observed in normal cells. In addition, overexpression of miR‑590‑5p significantly reduced the proliferation, migration and invasion of SAOS2 and U2OS cells in vitro, as well as inhibiting tumor sizes in vivo...

Immunology and immunotherapy of cancer is an expanding field in oncology, with recent great achievements obtained through the new successful approaches implemented to circumvent immune evasion, which is undoubtedly considered a novel hallmark of cancer. Translational research in this topic has revealed targets that can be modulated in the clinical setting with new compounds and strategies. Like most of the tumors, breast cancer is considered a complex and heterogeneous disease in which host immune responses have been also recently demonstrated of critical relevance...

Periostin is an extracellular matrix protein that actively contributes to tumor progression and metastasis. Here, we hypothesized that it could be a marker of bone metastasis formation. To address this question, we used two polyclonal antibodies directed against the whole molecule or its C-terminal domain to explore the expression of intact and truncated forms of periostin in the serum and tissues (lung, heart, bone) of wild-type and periostin-deficient mice. In normal bones, periostin was expressed in the periosteum and specific periostin proteolytic fragments were found in bones, but not in soft tissues...

PURPOSE: A meta-analysis of 22 randomized trials accrued from 1964 to 1986 demonstrated significantly higher rates of locoregional failure (LRF) and breast-cancer mortality in women with 1-3 positive nodes without postmastectomy radiotherapy (PMRT) after mastectomy (mast.). Recent data demonstrate that PMRT reduces distant metastases (DM) in women with pN1 disease. The challenge today is whether all patients with pathologic T1-2pN1 disease have similar substantial LRF/DM risk that routinely warrants PMRT...

BACKGROUND: Expressive writing interventions are shown to confer physical and psychological benefits for Caucasian cancer survivors. This study evaluated the health benefits of an expressive writing intervention among breast cancer patients in mainland China. METHODS: Stage I-III Chinese breast cancer survivors undergoing chemotherapy were recruited in Shanghai, China. They (n = 90) were randomly assigned to one of three conditions: a positive thinking group (PTC) to write about the positive aspects of their cancer experience; a self-regulation condition (SRC) to write about their stress and coping efforts, deepest feelings, and positive aspects of their cancer experience; or a cancer-fact group (CFC) to write about facts relevant to their cancer experience...

Early automatic breast cancer detection from mammograms is based on the extraction of lesions, known as microcalcifications (MCs). This paper proposes a new and simple system for microcalcification detection to assist in early breast cancer detection. This work uses the two most recognized public mammogram databases, MIAS and DDSM. We are introducing a MC detection method based on (1) Beucher gradient for detection of regions of interest (ROIs), (2) an annulus model for extraction of few and effective features from candidates to MCs, and (3) one classification stage with two different classifiers, k Nearest Neighbor (KNN) and Support Vector Machine (SVM)...
