INTRODUCTION: Previous studies have reported that specific depletion of mammalian sterile-like kinase (MST1) in the mouse liver driven Hepatocellular carcinoma (HCC). However, how the expression of MST1 was regulated in the progression of HCC remains largely unknown. MATERIALS AND METHODS: The expression of miR-3910 in the HCC tissues and cell lines were examined using q-PCR. The functions of miR-3910 in HCC were examined using MTT assay, Boyden chamber assay and soft agar assay...

Fast dissolving nanofiber (NF) composed of poly(vinyl alcohol) (PVA) and d-α-tocopheryl polyethylene glycol succinate (TPGS) was developed for locoregional delivery of phloretin to oral cancers. PVA/TPGS/phloretin NF with 321nm mean diameter and >90% drug entrapment efficiency was fabricated by an electrospinning method. Transformation of drug from crystalline to amorphous state was identified by solid-state studies. NF structure was changed to nanoparticles after its dispersing in the aqueous medium. PVA/TPGS/phloretin NF exhibited fast wetting property and smaller hydrodynamic size of dispersion, compared with PVA/phloretin NF...

Activated leukocyte cell adhesion molecule (ALCAM) is expressed on various cell types, including leukocytes, endothelial cells and certain tumor cells. While ALCAM expression on tumor cells has been linked with tumor invasion and metastatic spread, the contribution of ALCAM expressed in cells forming the tumor stroma to cancer progression has not been investigated. In this study, we made use of ALCAM-deficient (ALCAM(-/-)) mice to evaluate the role of ALCAM in lung tumor growth and metastasis. ALCAM(-/-) mice displayed an altered blood vascular network in the lung and the diaphragm, indicative of an angiogenesis defect...

OBJECTIVE: Surgical cytoreduction has been postulated to affect survival by increasing the efficacy of chemotherapy in ovarian cancer. We hypothesized that women with high-grade serous ovarian cancer, which usually responds to chemotherapy, would derive greater benefit from complete cytoreduction than those with histologic subtypes that are less responsive to chemotherapy, such as mucinous and clear cell carcinoma. METHODS: We conducted a retrospective cohort study of patients who underwent primary cytoreductive surgery and adjuvant chemotherapy for stage IIIC or IV epithelial ovarian cancer from 2011 to 2013 using data from the National Cancer Database...

This study seeks to determine whether uninsured breast cancer patients are more likely to present with advanced disease relative to insured patients. We retrospectively reviewed newly diagnosed breast cancer patients over a 27-month period. Patients were sorted based on insurance status at diagnosis. Demographic and tumor-specific data were collected and analyzed using nonparametric testing. We identified 276 breast tumors in 260 patients. Out of the 260 patients, 71 patients (27.3%) were uninsured and were more likely to be black (P < 0...

BACKGROUND: Current guidelines advocate no prophylactic dissection of the lateral neck compartment for papillary thyroid carcinoma (PTC) without clinical evidence of lateral neck metastasis (cN1b). However, lateral neck recurrence can affect patient treatment outcomes and quality of life. Therefore, this study examined the risk factors for lateral neck recurrence after the definitive treatment of PTC without cN1b. METHODS: The study enrolled 1928 consecutive patients who underwent total thyroidectomy between 2006 and 2012 for PTC without cN1b...

We experienced a giant biatrial myxoma concomitant with hepatocellular carcinoma. Most of myxomas originate from the left atrium, and biatrial myxomas are extremely rare. Excision of the giant cardiac tumor was performed to avoid risks of life-threatening complications. The resected mass was grossly composed of two parts with the border of interatrial septum and with the shape of peanut shell. Although microscopic examinations revealed enlarged vessels, hemorrhages and hemosiderosis in the left part and high cellularity with chronic inflammation in the right part, spindle-shaped cells in a loose myxoid stroma were observed in both parts of the tumor, consistent with the diagnosis of myxoma...

Head and neck squamous cell carcinoma (HNSCC) is the sixth most common malignancy worldwide. There is an urgent need to develop effective therapeutic approaches to prevent and treat HNSCC. Recent deep sequencing of the HNSCC genomic landscape revealed a multiplicity and diversity of genetic alterations in this malignancy. Although a large variety of specific molecules were found altered in each individual tumor, they all participate in only a handful of driver signaling pathways. Among them, the PI3K/mTOR pathway is the most frequently activated, which plays a central role in cancer initiation and progression...

PURPOSE: Screening mammography aims to improve breast cancer (BC) prognosis by increasing the incidence of early-stage tumours in order to decrease the incidence of late-stage cancer, but no reports have investigated these potential effects in an Australian population. Therefore we aimed to identify temporal trends in stage-specific BC in New South Wales (NSW), Australia, between 1972 and 2012. METHODS: An observational study of women who received a diagnosis of BC from 1972-2012 as recorded in the NSW Cancer Registry, a population-based registry with almost complete coverage and high rates of histological verification...

There are marked differences in the etiology of the major histological types of esophageal cancer (EC)-squamous cell carcinomas (ESCC) and adenocarcinomas (EAC). This study aimed to summarize the current scientific knowledge on modifiable risk factors for EC, by histological type, through a systematic review of meta-analyses referenced in PubMed and ISI Web of Knowledge. We identified 100 meta-analyses on risk factors for ESCC (n = 54), EAC (n = 43), or EC (n = 51). ESCC risk significantly increased with alcohol and maté drinking, smoking, red and processed meat consumption and human papillomavirus infection, while it was negatively associated with body mass index and consumption of fruit, vegetables, white meat, folate, and some carotenoids...

PURPOSE: Calcitonin is the most sensitive tumor marker of medullary thyroid carcinoma (MTC) and a calcium stimulation test is used to improve this sensitivity. In Japan, the electrochemiluminescence immunoassay (ECLIA) is currently the only test performed to measure serum calcitonin. There is a gender difference in the reference value of serum calcitonin; however, a reference upper limit for use with ECLIA has been reported only for women, but not for men. METHODS: We conducted the calcium stimulation test using ECLIA in 21 men with non-medullary thyroid carcinoma (non-MTC), before and after total thyroidectomy...

PURPOSE: We evaluated the long-term outcomes of clinical stage IA non-small cell lung cancer (NSCLC) patients with combined pulmonary fibrosis and emphysema (CPFE) who underwent lobectomy. METHODS: We reviewed the chest computed tomography (CT) findings and divided the patients into normal, fibrosis, emphysema and CPFE groups. We evaluated the relationships among the CT findings, the clinicopathological findings and postoperative survival. RESULTS: The patients were classified into the following groups based on the preoperative chest CT findings: normal lung, n = 187; emphysema, n = 62; fibrosis, n = 8; and CPFE, n = 17...

PURPOSE: Increased angiogenesis is a marker of aggressiveness in many cancers. Targeted radionuclide therapy of these cancers with angiogenesis-targeting agents may curtail this increased blood vessel formation and slow the growth of tumors, both primary and metastatic. CD105, or endoglin, has a primary role in angiogenesis in a number of cancers, making this a widely applicable target for targeted radioimmunotherapy. METHODS: The anti-CD105 antibody, TRC105 (TRACON Pharmaceuticals), was conjugated with DTPA for radiolabeling with (177)Lu (t 1/2 6...

INTRODUCTION: The lung is the most common site of distal metastasis in patients with hepatocellular carcinoma (HCC), as seen in more than half of patients with extrahepatic disease. The incidence of pulmonary metastasis in all patients with HCC, however, remains low (between 4.5% to 20%). Their presence, nevertheless, contraindicates curative locoregional therapies. The role of staging chest computed tomography (CT) before locoregional treatment is not well defined. This study aimed to assess the utility of pre-treatment chest CT prior to locoregional therapy...

While surgery is at the foundation of cancer treatment, its access is limited in low-income countries. Here, we describe development of a low-cost alternative therapy based on intratumoral ethanol injection suitable for resource-limited settings. Although ethanol-based tumor ablation is successful in treating hepatocellular carcinomas, the necessity for multiple treatments, injection of large fluid volumes, and decreased efficacy in treatment of non-capsulated tumors limit its applicability. To address these limitations, we investigated an enhanced ethanol ablation strategy to retain ethanol within the tumor through the addition of ethyl cellulose...
