Breast cancer is the leading cause of cancer-related death in women worldwide. Invasive ductal carcinoma (IDC) is the most frequent invasive form of breast cancer followed by metastasis. There is no accepted marker for distinguishing this form from other less aggressive forms of breast cancer. Therefore, finding new markers especially molecularly detectable ones are noteworthy. It has been shown that NOTCH1 has been overexpressed in the patients with breast cancer, but no study has investigated the expression of NOTCH1 and its correlation with other molecular and hormonal markers of breast cancer so far...

OBJECTIVE: The aim of this study was to evaluate the safety and efficacy of transarterial (chemo)embolization [TA(C)E] for the control of liver metastasis in patients with neuroendocrine tumors (NETs). METHODS: In this retrospective study, we enrolled 43 patients with metastatic NETs who had been treated with TA(C)E between December 1999 and June 2013 at the National Cancer Center Hospital, Tokyo or the National Cancer Center Hospital East, Kashiwa. We assessed tumor response, time to treatment failure (TTF), overall survival (OS), and frequency of adverse events in these patients, and attempted to identify predictors of TTF...

Exome and targeted sequencing studies have identified potential driver mutations for a variety of tumor types. Cutaneous squamous cell carcinoma (cSCC) is one of the most highly mutated cancers but is typically correlated with high survival rates and low rates of metastasis. Nevertheless, metastatic cSCC is a significant health threat; up to 8800 individuals are estimated to die yearly from this disease. As it is difficult to predict which cSCCs are more likely to metastasize, and because there are no targeted therapies specifically designated for metastatic cSCC, we performed exome and targeted sequencing of 18 metastatic and 10 primary cSCCs to identify mutations with potential therapeutic benefit...

There is conflicting literature as to whether the survival of patients with multiple melanoma is worse that this of single melanoma cases. We used extended Cox-proportional hazard models to estimate hazard-ratios (HR) of patients with multiple melanomas against single melanomas. Data from the nationwide Dutch Cancer Registry was used to retrieve cutaneous melanoma cases between 1994 and 2009 and linked with municipal records to assess the vital status. To account for the longer survival in the multiple melanoma cases we modelled multiple melanoma as time-varying variable, as well as Breslow thickness, histological subtype and nodal/distant metastasis...

BACKGROUND: Hepatocellular carcinoma (HCC) is a major cause of cancer-related mortality worldwide and the incidence is increasing as a result of growing hepatitis B and C virus infections. Primary clear cell carcinoma of the liver (PCCCL) is a rare subgroup of primary HCC, which has low metastatic potential and infrequently reported in literature. Retroperitoneal and intrahepatic metastasis of PCCCL has not been reported previously. CASE SUMMARY: Here, we present a 55-year-old male with retroperitoneal and intrahepatic metastasis of PCCCL who is managed with surgical method and transcatheter arterial chemoembolization (TACE) at our institution...

Recently, a few studies have raised the question of whether preoperative chemoradiotherapy (PCRT) is essential for all T3 rectal cancers. This case-matched study aimed to compare the long-term outcomes of surgery alone with those of PCRT + surgery for magnetic resonance imaging (MRI)-assessed T3ab (extramural depth of invasion ≤5 mm) and absent mesorectal fascia invasion (clear MRF) in mid/lower rectal cancer patients.From January 2006 to November 2012, 203 patients who underwent curative surgery alone (n = 118) or PCRT + surgery (n = 85) were enrolled in this retrospective study...

Background: HASH(0x53c2d90) Patients often ask oncologists how long a cancer has been present before causing symptoms or spreading to other organs. The evolutionary trajectory of cancers can be defined using phylogenetic approaches but lack of chronological references makes dating the exact onset of tumours very challenging. Patients and Methods: HASH(0x540c6e0) Here we describe the case of a colorectal cancer patient presenting with synchronous lung metastasis and metachronous thyroid, chest wall and urinary tract metastases over the course of five years...

Breast cancer is a disease with high heterogeneity. Many issues on tumorigenesis and progression are still elusive. It is critical to identify genes that play important roles in the progression of tumors, especially for tumors with poor prognosis such as basal-like breast cancer and tumors in very young women. To facilitate the identification of potential regulatory or driver genes, we present the Breast Cancer Integrative Platform (BCIP, http://omics.bmi.ac.cn/bcancer/). BCIP maintains multi-omics data selected with strict quality control and processed with uniform normalization methods, including gene expression profiles from 9,005 tumor and 376 normal tissue samples, copy number variation information from 3,035 tumor samples, microRNA-target interactions, co-expressed genes, KEGG pathways, and mammary tissue-specific gene functional networks...

Collagen XVII and integrin α6β4 have well-established roles as epithelial adhesion molecules. Their binding partner laminin 332 as well as integrin α6β4 are largely recognized to promote invasion and metastasis in various cancers, and collagen XVII is essential for the survival of colon and lung cancer stem cells. We have studied the expression of laminin γ2, collagen XVII and integrin β4 in tissue microarray samples of squamous cell carcinoma (SCC) and its precursors, actinic keratosis and Bowen's disease...

Clear Cell Renal Cell Carcinoma (CCRCC) is a lethal cancer with bad prognosis due to development of chemoresistance and recurrence of more aggressive tumors. Investigation of Gas6-mediated Axl signaling in CCRCC and endothelial cells reveals a Sunitinib resistant Gas6-Axl signaling that is sustained and enhanced and specifically triggers downstream AKT and PRAS40 activation in an intensified manner. Gas6-induced Axl signaling in presence of Sunitinib is also diversified displaying onset of Axl-dependent EGFR and METR activation and activation of classical MAPK pathways...

BACKGROUND: The metastases of a primary lung cancer over the thyroid gland are extremely rare. We report on an unusual presentation of thyroid metastasis of lung cancer in order to improve the management of similar cases. CASE PRESENTATION: Three years ago, a Moroccan male 59-year-old was admitted for dyspnea, dry cough, and chest pain. He had smoked about 30 cigarette packs a year. Clinical examination revealed a right thyroid nodule. Chest and neck computed tomography (CT) scan showed a proximal left tumor in contact with the pulmonary artery and revealed a suspected nodule in the right lobe of the thyroid with homolateral neck node...

BACKGROUND: Prostate cancer can be treated with several different modalities, including radiation treatment. Various prognostic tools have been developed to aid decision making by providing estimates of the probability of different outcomes. Such tools have been demonstrated to have better prognostic accuracy than clinical judgment alone. METHODS: A systematic review was undertaken to identify papers relating to the prediction of clinical outcomes (biochemical failure, metastasis, survival) in patients with prostate cancer who received radiation treatment, with the particular aim of identifying whether published tools are adequately developed, validated, and provide accurate predictions...

BACKGROUND: Accumulating evidence indicates that microRNA-27a (miR-27a) is involved in carcinogenesis and tumor progression. However, the exact function and molecular mechanism of miR-27a in gastric cancer remain unclear. METHODS: Quantitative real-time PCR (qRT-PCR) was used to quantify the expression of miR-27a and its target gene. The function of miR-27a in gastric cancer was investigated through in vitro and in vivo assays (MTT assay, colony formation assay, flow cytometry assay, wound healing assay, migration and invasion assay, immunohistochemistry (IHC), immunofluorescence (IF) and Western blot)...

BACKGROUND: Polymeric fibronectin (polyFN) assembled on suspended breast cancer cells is required for metastasis. Conceivably, drugs that target such polyFN may fight against cancer metastasis. While stilbene analogs trigger pro-apoptotic effect on attached cancer cells, whether they prevent polyFN assembly and metastasis of suspended cancer cells via an apoptosis-independent manner remains unexplored. METHODS: We depleted suspended Lewis lung carcinoma (LLC) cells of polyFN by silencing the endogenous FN expression or pterostilbene (PS) to examine whether metastasis of lung cancer cells could thus be suppressed...

BACKGROUND: Cancer cells are typically surrounded by stromal cells and embedded in extracellular matrix (ECM). The stromal compartment interacts with cancer cells to promote growth and metastasis. For decades, autologous fasciocutaneous flaps have been safely applied for breast reconstruction after mastectomy. In contrast, the safety of fat grafting (lipofilling) procedure has been under debate regarding the risk of cancer recurrence. METHODS: Harvested fat tissue (lipoaspirates) and dissected abdominal fat (DAF) were co-cultured with MCF-7 breast cancer cells...

BACKGROUND: Human epidermal growth factor receptor-2 (HER2) is regarded as an important and promising target in the treatment of HER2-positive breast cancers. However, the correlation of clinicopathological characteristics and prognostic significance of HER2 overexpression in gastric cancer patients remains unclear. Our aim was to clarify this issue. METHODS: Embase, PubMed, and the Cochrane Library were searched for relevant articles published up to May 2016. Outcomes of interest contained sex, age, tumor size, tumor site, tumor node metastasis (TNM) stage, distant metastasis, lymph node metastasis, Lauren's classification, differentiation grade, lymphovascular invasion, neural invasion, and multivariate analysis data for overall survival...

BACKGROUND: Autotransplantation of frozen-thawed ovarian tissue is a method to preserve ovarian function and fertility in patients undergoing gonadotoxic therapy. In oncology patients, the safety cannot yet be guaranteed, since current tumor detection methods can only exclude the presence of malignant cells in ovarian fragments that are not transplanted. We determined the need for a novel detection method by studying the distribution of tumor cells in ovaries from patients with breast cancer...
