Background: Breast cancer bone metastasis (BCBM)-specific genes have been reported without considering biological differences based on estrogen receptor (ER) status. The aims of this study were to identify BCBM-specific genes using our patient dataset and validate previously reported BCBM-specific genes, and to determine whether ER-status-related biological differences matter in identification of BCBM-specific genes. Methods: We used Affymetrix GeneChips to analyze 365 primary human epidermal growth factor receptor 2 (HER2)-negative invasive breast cancer specimens...

We present a case of cutaneous apocrine carcinoma arising in the axilla of a 71-year-old man. The tumor had a significant component of histiocytoid and signet-ring cells as well as in situ carcinoma within the apocrine glands. The cells expressed GATA3, gross cystic disease fluid protein 15, androgen receptor, and E-cadherin. Estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 were negative. Clinical correlation was required to rule out a metastasis from the breast or the gastrointestinal tract...

Rui Pang, Weibo Xia
Bone loss is common in clinical practice, such as health assessment of postmenopausal women, treatment of tumor metastasis, side-effects of glucocorticoids, and skeletal manifestations of inflammatory diseases. The imbalance of remodeling between bone resorption and bone formation, the pathophysiological basis of bone loss, increases bone fragility. The treatment of bone loss is mainly carried out from the treatment of osteoporosis. There are various pharmacological therapies for bone loss, which will be introduced in 3 aspects, including anti-resorptive agents, anabolic agents and new medications...

Bone pain is one of the most common and life-limiting complications of cancer metastasis to bone. Although the mechanism of bone pain still remains poorly understood, bone pain is evoked as a consequence of sensitization and excitation of sensory nerves (SNs) innervating bone by noxious stimuli produced in the microenvironment of bone metastases. We showed that bone is innervated by calcitonin gene-related protein (CGRP)(+) SNs extending from dorsal root ganglia (DRG), the cell body of SNs, in mice. Mice intratibially injected with Lewis lung cancer (LLC) cells showed progressive bone pain evaluated by mechanical allodynia and flinching with increased CGRP(+) SNs in bone and augmented SN excitation in DRG as indicated by elevated numbers of pERK- and pCREB-immunoreactive neurons...

Nephronectin (NPNT), a highly conserved extracellular matrix protein, plays an important role in regulating cell adhesion, differentiation, spreading and survival. NPNT protein belongs to epidermal growth factor (EGF)-like superfamily and exhibits several common structural determinants; including EGF-like repeat domains, MAM domain (Meprin, A5 Protein, and Receptor Protein-Tyrosine Phosphatase µ), RGD motif (Arg-Gly-Asp) and a coiled-coil domain. It regulates integrins-mediated signaling pathways via the interaction of its RGD motif with integrin α8β1...

INTRODUCTION: The introduction of resection prostheses paved the way for the development of limb-sparing surgery in patients with primary or metastatic bone tumours. After some time, the developing possibilities of treatment of extensive bone defects allowed for the use of resection prostheses as an emergency procedure in patients undergoing revision surgery due to hip implant loosening. The aim of this paper is to compare treatment outcomes in patients receiving the Modular Universal Tumour and Revision System (MUTARS) resection prosthesis during arthroplasty performed for different indications: treatment of a tumour metastasis and revision surgery in cases of implant loosening...

A challenge in precision medicine requires identification of actionable driver mutations. Critical to such effort is the deployment of sensitive and well-validated assays for mutation detection. Although identification of such alterations within the tumor tissue remains the gold standard, many advanced non-small cell lung cancer cases have only limited tissue samples, derived from small biopsies or fine-needle aspirates, available for testing. More recently, noninvasive methods using either circulating tumor cells or tumor DNA (ctDNA) have become an alternative method for identifying molecular biomarkers and screening patients eligible for targeted therapies...

Solitary metastasis of a carcinoma to carpal bone is extremely rare. Metastases of renal cell carcinoma (RCC) usually occur in a multiple fashion and there has been no report to date of a solitary metastasis to trapezium from RCC. The tumor was excised and reconstructed with iliac bone transplantation. 2 years and 6 months after surgery, there is no local recurrence with minimal functional loss.

INTRODUCTION: Hepatocellular carcinomas (HCC) that are very large in size are a very rare finding in young adult. The malignant transformation of a pigmented hepatocellular adenoma (HCA) with beta-Catenin activation is a possible cause for appearance of HCC. PRESENTATION OF CASE: We present the case of a 33-year-old male with a huge HCC with bone metastasis, emerged from pigmented HCA with beta-Catenin activation. As a two-stage surgical procedure, a left hepatectomy followed by a partial rib resection was performed...

It is known that V-ATPases (vacuolar H+-ATPase) are involved in breast cancer growth and metastasis. Part of this action is similar to their role in osteoclasts, where they're involved in extracellular acidification and matrix destruction; however, the roles of their subunits in cancer cell proliferation, signaling, and other pro-tumor actions are not well established. Analysis of TCGA data shows that V-ATPase subunit Atp6v1c1 is overexpressed or amplified in 34% of human breast cancer cases, with a 2-fold decrease in survival at 12 years...

We previously proposed that one of the unwanted side effects of chemotherapy and radiotherapy is the increase in several peptide- and non-peptide based chemoattractants in damaged tissues, leading to induction of a prometastatic microenvironment for remaining cancer cells. Herein, we turned out our attention to a potential role of bioactive phospholipids (BphsLs), such as sphingosine-1-phosphate (S1P), ceramide-1-phosphate (C1P), lysophosphatidylcholine (LPC), and lysophosphatidic acid (LPA) in lung cancer (LC) metastasis...

A presumptive diagnosis of bone metastasis can be easily made when a patient with a history of colorectal cancer develops bone lesions that are seen on follow-up imaging. In this case report, we describe a patient whose multiple bone lesions were wrongly attributed to a recurrence of rectal cancer rather than being identified as multiple myeloma lesions. When clinicians detect new, abnormal, bony lesions in a patient with a previous history of cancer, they should consider diseases such as multiple myeloma in their differential diagnosis...

Bone metastasis from primary cancer sites creates diagnostic and therapeutic challenges. Calcified bone is difficult to biopsy due to tissue hardness and patient discomfort, thus limiting the frequency and availability of bone/bone marrow biopsy material for molecular profiling. In addition, bony tissue must be demineralized (decalcified) prior to histomorphologic analysis. Decalcification processes rely on three main principles: (a) solubility of calcium salts in an acid, such as formic or nitric acid; (b) calcium chelation with ethylenediaminetetraacetic acid (EDTA); or (c) ion-exchange resins in a weak acid...
