However, tumor detection of breast ultrasound (US) image is still a challenging work in computer-aided diagnosis (CAD).

Novel Methylated DNA Markers Discriminate Advanced Neoplasia in Pancreatic Cysts: Marker Discovery, Tissue Validation, and Cyst Fluid Testing.

Pancreatic cystic lesions (PCLs) may be precancerous. Those likely to harbor high-grade dysplasia (HGD) or pancreatic cancer (PC) are targets for surgical resection. Current algorithms to predict advanced neoplasia (HGD/PC) in PCLs lack diagnostic accuracy. In pancreatic tissue and cyst fluid (CF) from PCLs, we sought to identify and validate novel methylated DNA markers (MDMs) that discriminate HGD/PC from low-grade dysplasia (LGD) or no dysplasia (ND).

Evaluation of the antileukemic effects of neurokinin-1 receptor antagonists, aprepitant, and L-733,060, in chronic and acute myeloid leukemic cells.

Neurokinin-1 receptor (NK1R) antagonists are known for their anxiolytic, antiemetic, anticancer, and anti-inflammatory effects. Aprepitant is used in vomiting and nausea, which are the most common side-effects of patients undergoing chemotherapy for cancer. L-733,060 has been shown to have anxiolytic and antidepressant effects in animal studies and anticancer effect in in-vitro studies. Previous anticancer activity studies with NK1R antagonists have reported that NK-1 antagonists have an antitumoral activit...

Andrographolide sensitizes Hep-2 human laryngeal cancer cells to carboplatin-induced apoptosis by increasing reactive oxygen species levels.

Andrographolide is a natural diterpenoid from Andrographis paniculata that has been proposed as an anticancer agent as well as a chemosensitizer for use in combination with anticancer drugs. Carboplatin is the first-line chemotherapeutic agent for advanced laryngeal carcinoma. However, the clinical efficacy of carboplatin is limited by drug resistance and side effects. The aim of this study was to investigate whether andrographolide has a synergistic antitumor effect with carboplatin on human laryngeal canc...

Imaging for Barrett's esophagus: state of the art.

Barrett's esophagus is the premalignant condition for esophageal cancer and the diagnosis of esophageal adenocarcinoma on index endoscopy is increasing. Many advanced endoscopic techniques are available and aim to identify Barrett's esophagus-associated neoplasia earlier, thereby preventing progression into malignancy.

Incidental Finding of Acute Lymphocytic Leukemia in a Prostate-Specific Membrane Antigen PET/CT.

PSMA PET/CT is known to show uptake in various benign and malignant processes. The following PSMA PET/CT was performed for prostate carcinoma staging (Gleason 3 + 4 left apex; PSA 5.8). It shows incidental diffuse PSMA marrow uptake, not typical for prostate metastatic disease. No treatment had been commenced at the time of the scan. Serology and bone marrow biopsy showed B-cell acute lymphocytic leukemia. Focal PSMA uptake in the right ischium was correlated with a T1 hypointense lesion on a previous MRI a...

68Ga-Prostate-Specific Membrane Antigen-11 PET/CT: Incidental Finding of a Vestibular Schwannoma.

A 77-year-old man with newly diagnosed prostate adenocarcinoma with a total prostate-specific antigen level of 6.4 ng/mL and Gleason score 7 (4 + 3) was referred to Ga-prostate-specific membrane antigen-11 (PSMA) PET/CT for initial staging. An intense focal PSMA uptake was shown in the right peripheral zone of the prostate gland consistent with the primary tumor. Additionally, PET/CT demonstrated a PSMA-avid soft tissue mass in the left cerebellopontine angle. The patient had a history of left-sided sensori...

68Ga-PSMA PET/CT Uptake in the Ureter Caused by Ligand Expression in Urothelial Cancer.

Ga-PSMA PET/CT has become a well-established imaging modality to detect prostate cancer (PCa) metastases in biochemical recurrence. Despite its claimed specificity for PCa, Ga-PSMA uptake in tissues unrelated to PCa, particularly in the neovascular tissue of other cancers, has been reported in numerous studies. A 73-year-old man underwent Ga-PSMA PET/CT for biochemical recurrence of PCa 7 years after radical prostatectomy. The Ga-PSMA PET/CT showed 1 lesion with PSMA uptake in the distal left ureter. Histol...

Normal Variant 18F-Sodium Fluoride Uptake in the Falx Cerebri Ossification.

Falx cerebri ossification is an incidental finding. Mostly it is easy to diagnose, but can be challenging in few cases, and should be distinguished from calcified meningioma, hematoma, and meningeal infiltration. We report a case of a 46-year-old woman with breast cancer complaining of back pain. F-NaF PET/CT images show focal increase uptake at facet joints of L5/S1 vertebrae and both knees joints, suggesting degenerative disease. There is normal variant F-NaF uptake noted in the ossification at the falx c...

Determination of Cetuximab in Plasma by Liquid Chromatography-High-Resolution Mass Spectrometry Orbitrap With a Stable Labeled 13C,15N-Cetuximab Internal Standard.

Cetuximab (CTX) is a chimeric IgG1 Kappa monoclonal antibody used to treat head and neck cancer and colorectal cancer. Previous clinical studies indicated that the pharmacokinetics of CTX influences patient survival. Thus, individualizing CTX treatment by measuring trough levels of the drug in plasma could have a major impact on clinical efficacy.

Molecular dissection of the oncogenic role of ETS1 in the mesenchymal subtypes of head and neck squamous cell carcinoma.

Head and Neck Squamous Cell Carcinoma (HNSCC) is a heterogeneous disease of significant mortality and with limited treatment options. Recent genomic analysis of HNSCC tumors has identified several distinct molecular classes, of which the mesenchymal subtype is associated with Epithelial to Mesenchymal Transition (EMT) and shown to correlate with poor survival and drug resistance. Here, we utilize an integrated approach to characterize the molecular function of ETS1, an oncogenic transcription factor specifi...

A Warburg effect targeting vector designed to increase the uptake of compounds by cancer cells demonstrates glucose and hypoxia dependent uptake.

Glycoconjugation to target the Warburg effect provides the potential to enhance selective uptake of anticancer or imaging agents by cancer cells. A Warburg effect targeting group, rationally designed to facilitate uptake by glucose transporters and promote cellular accumulation due to phosphorylation by hexokinase (HK), has been synthesised. This targeting group, the C2 modified glucose analogue 2-(2-[2-(2-aminoethoxy)ethoxy]ethoxy)-D-glucose, has been conjugated to the fluorophore nitrobenzoxadiazole to ev...

Substituted anthraquinones represent a potential scaffold for DNA methyltransferase 1-specific inhibitors.

In humans, the most common epigenetic DNA modification is methylation of the 5-carbon of cytosines, predominantly in CpG dinucleotides. DNA methylation is an important epigenetic mark associated with gene repression. Disruption of the normal DNA methylation pattern is known to play a role in the initiation and progression of many cancers. DNA methyltransferase 1 (DNMT1), the most abundant DNA methyltransferase in humans, is primarily responsible for maintenance of the DNA methylation pattern and is consider...

Composite spheres made of bioengineered spider silk and iron oxide nanoparticles for theranostics applications.

Bioengineered spider silk is a biomaterial that has exquisite mechanical properties, biocompatibility, and biodegradability. Iron oxide nanoparticles can be applied for the detection and analysis of biomolecules, target drug delivery, as MRI contrast agents and as therapeutic agents for hyperthermia-based cancer treatments. In this study, we investigated three bioengineered silks, MS1, MS2 and EMS2, and their potential to form a composite material with magnetic iron oxide nanoparticles (IONPs). The presence...

Photoacoustic imaging of clofazimine hydrochloride nanoparticle accumulation in cancerous vs normal prostates.

Prostate cancer was the most common form and had the second highest death rate of male cancer in the United States in 2015. Current diagnosis techniques, such as prostate-specific antigen tests, transrectal ultrasound scans, and biopsies, are often inconclusive, and in the latter case, invasive. Here, we explore the use of clofazimine hydrochloride nanoparticles (CFZ-HCl NPs), a repurposed formulation from an FDA-approved antimycobacterial agent, as a photoacoustic contrast agent for the evaluation of prost...

Combination of red blood cell distribution width and body mass index (COR-BMI) predicts in-hospital mortality in patients with different diagnoses?

The combination of red blood cell distribution width and body mass index (COR-BMI) is indicated as a new prognostic index of survival in patients with laryngeal cancer. However, the ability of this prediction in other types of cancer or whether its use can be expanded to non-oncological patients is unknown. The aim of this study was to investigate the prediction of prognosis of in-hospital mortality of the COR-BMI in oncological and non-oncological patients.

Histone Methyltransferase SETDB1 Promotes Colorectal Cancer Proliferation through the STAT1-CCND1/CDK6 Axis.

Upregulation of histone methyltransferase SETDB1 is associated with poor prognosis in cancer patients. However, the mechanism of oncogenicity of SETDB1 in cancer is hitherto unknown. Here, we show that SETDB1 is upregulated in human colorectal cancer (CRC) where its level correlates with poor clinical outcome. Ectopic SETDB1 promotes CRC cell proliferation, whereas SETDB1 attenuation inhibits this process. Flow cytometry reveals that SETDB1 promotes proliferation by driving the CRC cell cycle from G0/G1 pha...

Intra-individual variation of circulating tumour DNA in lung cancer patients.

Circulating tumour DNA (ctDNA) has been increasingly incorporated into the treatment of cancer patients. ctDNA is generally accepted as a powerful diagnostic tool, whereas the utility of ctDNA to monitor disease activity needs to be fully validated. Central to this challenge is the question of whether changes in longitudinal ctDNA measurements reflect disease activity or merely biological variation. Thus, the aim of this study was to explore the intra-individual biological variation of ctDNA in lung cancer ...

Vitamin D differentially regulates colon stem cells in patient-derived normal and tumor organoids.

Intestine is a major target of vitamin D and several studies indicate an association between vitamin D deficiency and inflammatory bowel diseases (IBD), but also increased colorectal cancer (CRC) risk and mortality. However, the putative effects of 1α,25-dihydroxyvitamin D (calcitriol), the active vitamin D metabolite, on human colonic stem cells are unknown. Here we show by immunohistochemistry and RNAscope in situ hybridization that vitamin D receptor (VDR) is unexpectedly expressed in LGR5 colon stem ce...
