Malignant gastrointestinal neuroectodermal tumor (GNET) is an aggressive rare tumor, primarily occurring in young adults with frequent local-regional metastases and recurrence after local control. The tumor is characterized by the presence of EWSR1-ATF1 or EWSR1-CREB1 and immunohistochemical positivity for S-100 protein without melanocytic marker positivity. Due to poor responses to standard sarcoma regimens, GNET has a poor prognosis, and development of effective systemic therapy is desperately needed to treat these patients...

Metastasis is the cause of most prostate cancer (PCa) deaths and has been associated with circulating tumor cells (CTCs). The presence of ≥5 CTCs/7.5mL of blood is a poor prognosis indicator in metastatic PCa when assessed by the CellSearch® system, the "gold standard" clinical platform. However, ~35% of metastatic PCa patients assessed by CellSearch® have undetectable CTCs. We hypothesize that this is due to epithelial-to-mesenchymal transition (EMT) and subsequent loss of necessary CTC detection markers, with important implications for PCa metastasis...

BACKGROUND: An anti-programmed cell death protein 1 monoclonal antibody, nivolumab, is one of the most effective drugs for advanced melanoma. Tumor cell-derived or immune cell-derived markers and clinical predictors such as serum lactate dehydrogenase (LDH) and cutaneous adverse events, have already been described as prognostic factors for advanced melanoma treated with nivolumab. We sought to identify further clinical predictors that can be determined in routine clinical practice. METHODS: We retrospectively analyzed clinical findings of 98 consecutive patients with unresectable stage III or IV melanoma treated with nivolumab, at the National Cancer Center Hospital or at Keio University Hospital, in Tokyo, Japan, between July 2014 and July 2016...

INTRODUCTION: Liver is the most common site of distant metastasis in colorectal cancer (CRC). Early diagnosis and appropriate treatment selection decides overall prognosis of patients. However, current diagnostic measures were basically imaging but not functional. Circulating tumor cells (CTCs) known as hold the key to understand the biology of metastatic mechanism provide a novel and auxiliary diagnostic strategy for CRC with liver metastasis (CRC-LM). RESULTS: The expression of CD133+ and CD133+CD54+CD44+ cellular subpopulations were higher in the peripheral blood of CRC-LM patients when compared with those without metastasis (P<0...

The co-stimulatory ligands of B7-family have been confirmed to play an important role in negatively regulating the T-cell mediated anti-tumor immunity. In addition, these inhibitory molecules are also aberrantly expressed on various human cancers tissues, and significantly associated with cancer progression and patients' poor prognoses. We have previously reported that B7-H3 and B7-H4 ligands are highly expressed in human esophageal cancer tissues. Herein, we tried to further analyze the value of their combined expression on prognostic prediction for esophageal cancer patients...

Melanoma is a particularly virulent human cancer, due to its resistance to conventional treatments and high frequency of metastasis. Melanomas contain a fraction of cells, the melanoma-initiating cells (MICs), responsible for tumor propagation and relapse. Identification of the molecular pathways supporting MICs is, therefore, vital for the development of targeted treatments. One factor produced by melanoma cells and their microenvironment, insulin-like growth factor-1 (IGF- 1), is linked to epithelial-mesenchymal transition (EMT) and stemness features in several cancers...

Amplification of 11q13.3 is a frequent event in human cancers, including head and neck squamous cell carcinoma. This chromosome region contains several genes that are potentially cancer drivers, including FADD (Fas associated via death domain), an apoptotic effector that was previously identified as a novel oncogene in laryngeal/pharyngeal cancer. This study was designed to explore the role of FADD in oral squamous cell carcinomas (OSCCs) samples from Taiwanese patients, by assessing copy number variations (CNVs) and protein expression and the clinical implications of these factors in 339 male OSCCs...

Altered levels of naturally occurring anti-glycan antibodies (AGA) circulating in human blood plasma are found in different pathologies including cancer. Here the levels of AGA directed against 22 negatively charged (sialylated and sulfated) glycans were assessed in high-grade serous ovarian cancer (HGSOC, n = 22) patients and benign controls (n = 31) using our previously developed suspension glycan array (SGA). Specifically, the ability of AGA to differentiate between controls and HGSOC, the most common and aggressive type of ovarian cancer with a poor outcome was determined...

In the present study we have investigated whether Caveolin-1 expression in non-malignant and malignant prostate tissue is a potential prognostic marker for outcome in prostate cancer patients managed by watchful waiting. Caveolin-1 was measured in prostate tissues obtained through transurethral resection of the prostate from 395 patients diagnosed with prostate cancer. The majority of the patients (n = 298) were followed by watchful waiting after diagnosis. Tissue microarrays constructed from malignant and non-malignant prostate tissue were stained with an antibody against Caveolin-1...

Mammary analog secretory carcinoma (MASC) is a recently described tumor of the salivary glands named for its morphological and molecular similarity to secretory carcinoma of the breast. Many primary carcinomas arising from the adnexal glands also share similar morphology to those arising from the breast. Brandt et al first described primary cutaneous MASC in 2009 and since then only 2 other cases have been reported. Herein, we describe a long-standing mass on the arm of an otherwise healthy 40-year-old female...

CONTEXT: -CDH17, which is expressed in the intestinal epithelium, is a novel oncogene involved in tumor invasion and metastasis. A panel consisting of cytokeratin (CK) 7, CD20, and CDX2 antibodies is typically used to diagnose gastrointestinal adenocarcinomas. However, studies have shown that CDH17 is a highly specific marker for gastrointestinal adenocarcinoma and may be important in clinical diagnosis. OBJECTIVE: -To evaluate the sensitivity and specificity of CDH17, CK20, and CDX2 antibodies in neoplastic tissues, with emphasis on colon, stomach, and esophageal gastrointestinal lineage...

Immunotherapy approaches for pancreatic ductal adenocarcinoma (PDAC) have met with limited success. It has been postulated that a low mutation load may lead to a paucity of T cells within the tumor microenvironment (TME). However, it is also possible that while neoantigens are present, an effective immune response cannot be generated due to an immune suppressive TME. To discern whether targetable neoantigens exist in PDAC, we performed a comprehensive study using genomic profiles of 221 PDAC cases extracted from public databases...

Recent technological advancements in rare cell analysis have facilitated the detection of circulating tumor cells (CTCs) in the blood of patients diagnosed with breast and other types of cancers. Numerous clinical studies involving the enumeration of CTCs in breast cancer patients have unequivocally demonstrated the prognostic value of these cells. Evidence from recent molecular studies indicates that CTCs may be potential surrogate markers for systemic disease. As such, real-time assessment of therapeutic biomarkers in breast CTCs, such as the estrogen receptor (ER) and the human epidermal growth factor receptor 2 (HER2), may have a tremendous impact in guiding-targeted cancer therapy...

Adult onset Still's disease (AOSD) is a chronic inflammatory disorder involving multiple systems. The symptoms mimic those of lymphomas, therefore, the diagnosis of lymphoma needs to be excluded prior to establishing the diagnosis of AOSD. Another similar condition is dermatopathic lymphadenopathy (DL). In DL, the histopathological appearance of lymph node biopsy may also mimic AOSD. The DL is associated with several systemic pathologies, such as malignant lymphomas, and rarely AOSD. We present a case of a 43-year-old male presented with 3 months history of fatigue, fever, and lymphadenopathy...

Advanced glycation end products (AGEs) are major inflammatory mediators in diabetes, affecting atherosclerosis progression via macrophages. Metformin slows diabetic atherosclerosis progression through mechanisms that remain to be fully elucidated. The present study of murine bone marrow derived macrophages showed that (1) AGEs enhanced proinflammatory cytokines (interleukin-1β (IL-1β), IL-6, and tumor necrosis factor-α (TNF-α)) mRNA expression, RAGE expression, and NFκB activation; (2) metformin pretreatment inhibited AGEs effects and AGEs-induced cluster designation 86 (CD86) (M1 marker) expression, while promoting CD206 (M2 marker) surface expression and anti-inflammatory cytokine (IL-10) mRNA expression; and (3) the AMPK inhibitor, Compound C, attenuated metformin effects...

The skeleton represents a common site of metastases for osteotropic cancers such as prostate and breast tumors and novel therapeutic targets and new markers for the monitoring of bone lesions are urgently needed. The formation of bone metastases is a complex process that starts at the level of the confined tumor and that is characterized by a dynamic crosstalk between the primary cancer and the future metastatic site, the bone. Factors released by the primary tumor contribute to prepare a fertile "soil", where a "pre-metastatic niche" is established prior to future colonization by cancer cells...

A 69-year-old man was referred to our hospital with the chief complaint of a painless right scrotal swelling gradually increasing in size during the past 10 years. Testicular tumor markers were within the normal range. Ultrasonography showed an intrascrotal homogeneous mass. Computed tomography and magnetic resonance imaging revealed an inguinal mass, which mainly consisted of fat signal area and partially well enhanced in vascular density. Pre-surgical diagnosis was liposarcoma of spermatic cord estimated by radiographic examination and resection of the right intrascrotal tumor with high inguinal orchitectomy was performed...

A 74-year-old man with IgG4-related cholangitis had been treated with steroids for 1 year. In the outpatient clinic, elevated levels of the tumor marker CA19-9 and serum IgG4 were observed. Abdominal enhanced CT showed a 20mm hypovascular tumor in the pancreatic head. ERCP showed narrowingof the main pancreatic duct in the pancreatic head with slight caudal dilation and stricture of the lower common bile duct. We made a diagnosis of pancreatic cancer, and the patient underwent pancreaticoduodenectomy. Pathological examination of the resected tissue revealed a well-differentiated adenocarcinoma surrounded by autoimmune pancreatitis, characteristic of lymphoplasmacytic sclerosingpancreatitis...
