Angiomatoid fibrous histiocytoma is an unusual soft tissue tumor, mostly arising in the subcutaneous fibro-adipose tissue of children and young adults and measuring a few centimeters in greatest dimension. Reported herein is a unique case of angiomatoid fibrous histiocytoma containing epithelium-lined cystic structures. This large tumor (12 cm) was located(More)
The serine/threonine kinase B-Raf plays a key role in the Ras/Raf/MEK/ERK pathway that relays extracellular signals for cell proliferation and survival. Several types of human malignancies harbor activating BRAF mutations, most frequently a V600E substitution. The epidermal growth factor receptor (EGFR), a transmembrane tyrosine kinase (TK) receptor that(More)
Research focus in neuro-oncology has shifted in the last decades towards the exploration of tumor infiltration by a variety of immune cells and their products. T cells, macrophages, B cells, and mast cells (MCs) have been identified. A systematic review of the literature was conducted by searching PubMed, EMBASE, Google Scholar, and Turning Research into(More)
BACKGROUND The aim of the present study was to investigate the efficacy of adjuvant dose-dense sequential chemotherapy with epirubicin, paclitaxel, and CMF in subgroups of patients with high-risk operable breast cancer, according to tumor subtypes defined by immunohistochemistry (IHC). MATERIALS AND METHODS Formalin-fixed paraffin-embedded (FFPE) tumor(More)
The HER2 gene has been established as a valid biological marker for the treatment of breast cancer patients with trastuzumab and probably other agents, such as paclitaxel and anthracyclines. The TOP2A gene has been associated with response to anthracyclines. Limited information exists on the relationship of HER2/TOP2A gene status in the presence of(More)
Herstatin (HST) is an alternatively spliced HER2 product with growth-inhibitory properties in experimental cancer systems. The role of HST in adult human tissues and disease remains unexplored. Here, we investigated HST expression at the mRNA and protein (immunohistochemistry [IHC]) level in parallel with parameters reflecting HER activation in 187 breast(More)
The Androgen Receptor (AR) is a potential prognostic marker and therapeutic target in breast cancer. We evaluated AR protein expression in high-risk breast cancer treated in the adjuvant setting. Tumors were subtyped into luminal (ER+/PgR±/AR±), molecular apocrine (MAC, [ER-/PgR-/AR+]) and hormone receptor negative carcinomas (HR-negative, [ER-/PgR-/AR-]).(More)
EGFR has been associated with unfavourable prognosis in patients with triple-negative breast carcinomas, although little is known about EGFR activation in these tumours. In a series of breast carcinomas (archived formalin fixed tumours, n=100), we investigated EGFR phosphorylation status at Tyr992 (pEGFR-Y992) and Tyr1068 (pEGFR-Y1068) by(More)
OBJECTIVE Peptide receptor radionuclide therapy (PRRT) is dependent upon binding of radiolabelled peptides to their respective receptor expressing cells. The main objective of this study was to characterize the expression of somatostatin receptor (SSTR) subtypes in non-medullary thyroid cancers in order to be able to recommend the use of PRRT as a treatment(More)
