The identification of tumor biomarkers to support early diagnosis and tumor progression monitoring may potentially reduce the mortality of gastric cancer (GC). The present study aimed to detect novel tumor‑associated antigens from the AGS GC cell line, and to identify their associated autoantibodies in sera from patients with GC by proteomics‑based approaches. Proteins from AGS cell lysates were isolated using two‑dimensional polyacrylamide gel electrophoresis, and western blotting was subsequently performed, to determine autoantibody responses in sera derived from patients with GC and healthy individuals...

Cardiotoxicity is a well-known side effect of doxorubicin (DOX), but the mechanisms leading to this phenomenon are still not completely clear. Prediction of drug-induced dysfunction onset is difficult and is still largely based on detection of cardiac troponin (cTn), a circulating marker of heart damage. In the last years, several investigations focused on the possible involvement of microRNAs (miRNAs) in DOX-induced toxicity in vitro, with contrasting results. Recently, several groups employed animal models to mimic patient's condition, investigate the biological pathways perturbed by DOX, and identify diagnostic markers of cardiotoxicity...

The putative tumor suppressor gene WW domain containing oxidoreductase (WWOX) spans a common fragile site (CFS) on chromosome 16q23.3. CFSs are regions of profound genomic instability and sites for genomic deletions in cancer cells. Therefore, WWOX is structurally altered in diverse nonhematological cancer types. However, the function of WWOX in hematological tumor types, including multiple myeloma (MM) and monoclonal gammopathy of undetermined significance (MGUS) remains unclear. WWOX expression and methylation in patients with MM, MGUS, or noninvasive lymphoma (control) were analyzed using reverse transcription- and methylation specific-polymerase chain reaction analysis...

The aim of the present study was to evaluate the short-term surgical outcomes of laparoscopic intersphincteric resection (ISR) for a lower rectal tumor in comparison with a case-control series of patients undergoing open ISR. Quality of life factors and anal function were also evaluated. Between July 2008 and April 2013, 103 patients with lower rectal cancer underwent laparoscopic surgery at the Surgical Oncology Department of Gifu University School of Medicine. A total of 25 patients with lower rectal cancer underwent ISR, and 19/25 patients who underwent laparoscopic ISR were compared with the control group of 6 patients who underwent open ISR...

Lung cancer is the number one cause of cancer-related death worldwide, and is often detected in the later stages. Use of low-dose chest computed tomography in at-risk patients provides earlier detection and is being adopted as the standard screening tool, replacing less precise methods of radiography and sputum cytology. In the past, late detection of disease meant that rehabilitation interventions attempted to salvage function and to improve aerobic capacity to the point where patients could tolerate the sometimes-extensive oncologic treatment, including lobectomy or pneumonectomy...

PURPOSE: As growing numbers of long-term cancer survivors faced with the cardiac side effects by anthracycline treatment, it is necessary to explore the optimal monitoring method for the early detection of cardiac toxicity. METHODS: We conducted a retrospective analysis of 82 consecutive patients with diffuse large B-cell lymphoma treated with chemotherapy. Echocardiographic Doppler imaging-derived Tei index and mitral annular peak systolic velocity (Sm) measured by tissue Doppler imaging TDI, serum high-sensitivity cardiac troponin T (hs-cTnT) levels, and left ventricular ejection fraction (LVEF) by multigated radionuclide angiography (MUGA) were obtained before, after 2-4, and after 6-8 chemotherapy cycles...

Colorectal cancer (CRC) is the second most common cancer in women and the third most common in men. Adenocarcinoma accounts for 90% of CRC cases. There has been accumulating evidence in support of the cancer stem cell (CSC) concept of cancer which proposes that CSCs are central in the initiation of cancer. CSCs have been the focus of study in a range of cancers, including CRC. This has led to the identification and understanding of genes involved in the induction and maintenance of pluripotency of stem cells, and markers for CSCs, including those investigated specifically in CRC...

Earlier detection of colorectal cancer greatly improves prognosis, largely through surgical excision of neoplastic polyps. These include benign adenomas which can transform over time to malignant adenocarcinomas. This progression may be associated with changes in full blood count indices. An existing risk algorithm derived in Israel stratifies individuals according to colorectal cancer risk using full blood count data, but has not been validated in the UK. We undertook a retrospective analysis using the Clinical Practice Research Datalink...

Colorectal cancer (CRC) a leading cause of death by cancer, and screening programs for its early identification are at the heart of the increasing survival rates. To motivate population participation, non-invasive, accurate, scalable and cost-effective diagnosis methods are required. Blood fluorescence spectroscopy provides rich information that can be used for cancer identification. The main challenges in analyzing blood fluorescence data for CRC classification are related to its high dimensionality and inherent variability, especially when analyzing a small number of samples...

Interpretation of mammography for breast cancer (BC) screening can confer a mortality benefit through early BC detection, can miss a cancer that is present or fast growing, or can result in false-positives. Efforts to improve screening outcomes have mostly focused on intensifying imaging practices (double instead of single-reading, more frequent screens, or supplemental imaging) that may add substantial resource expenditures and harms associated with population screening. Less attention has been given to making mammography screening practice 'smarter' or more efficient...

The development of cervical cancer is frequently accompanied by the integration of human papillomaviruses (HPV) DNA into the host genome. Viral-cellular junction sequences, which arise in consequence, are highly tumor specific. By using these fragments as markers for tumor cell origin, we examined cervical cancer clonality in the context of intra-tumor heterogeneity. Moreover, we assessed the potential of these fragments as molecular tumor markers and analyzed their suitability for the detection of circulating tumor DNA in sera of cervical cancer patients...

Early diagnosis of pancreatic cancer is critical to reduce the mortality rate of this disease. Current biological analysis approaches cannot robustly detect several low abundance pancreatic cancer biomarkers in sera, limiting the clinical application of these biomarkers. This study demonstrates a novel system for multiplex detection of pancreatic biomarkers CA19-9, MMP7 and MUC4 in sera samples with high sensitivity. Measuring the levels of these biomarkers in pancreatic cancer patients, pancreatitis patients, and healthy individuals reveals the unique expression pattern of these markers in pancreatic cancer patients, suggesting the great potential of using this approach for early diagnostics of pancreatic cancers...

Colorectal cancer is a multistep process affecting several signaling pathways including EGFR (epidermal growth factor receptor), a therapeutic target for metastatic disease. Our aim was to characterize the mutational and expression profiles of the EGFR pathway in colorectal tumors and to integrate these results according to five previously defined groups. We screened seven genes for mutations ( KRAS-BRAF-PIK3CA-PIK3R1-AKT1-MAP2K1-PTEN) and six proteins (EGFR-p110α-p85α-PTEN-phosphoAKT-phosphoMEK1) by immunohistochemistry, PTEN deletion, and MSI...

Cardiotoxicity is an important complication of several cancer therapeutic agents. Several well established and newer anticancer therapies such as anthracyclines, trastuzumab and other HER2 receptor blockers, antimetabolites, alkylating agents, tyrosine kinase inhibitors (TKIs), angiogenesis inhibitors, and checkpoint inhibitors are associated with significant cardiotoxicity. Cardiovascular imaging employing radionuclide imaging, echocardiography and magnetic resonance imaging are helpful in early detection and prevention of overt heart failure secondary to cardiotoxicity of cancer therapy...
