Lymphovascular invasion (LVI), encompassing blood and lymphatic vessel invasion, is an important event in tumourigenesis. Macrophages within the tumour microenvironment are linked to the presence of LVI and angiogenesis. This study investigates the role of macrophage-derived, caspase-1-dependent interleukin-1beta (IL-1β) in an in vitro model of LVI. IL-1β significantly augmented the adhesion and transmigration of breast cancer cell lines MCF7 and MDA-MB-231 across endothelial cell barriers. MDA-MB-231 and MCF7 showed a higher percentage of adhesion to lymphatic endothelial cells than blood endothelial cells following endothelial cell IL-1β stimulation (P < 0...

PURPOSE: Allogeneic stem cell transplantation may cure approximately 50% of patients, however, a significant part of the other half might benefit from a high-quality palliative care medicine at the end of life. Somatic, psychic and spiritual needs of these patients may differ from those of patients suffering from incurable solid tumours and are not comprehensively evaluated so far. METHODS: To address this question, data from charts of 123 patients who have died after allogeneic stem cell transplantation were extracted...

Particulate-bound poly-aromatic hydrocarbons (PAHs) are of great concern due to their mutagenicity and carcinogenicity effect on human health. In this context, identification, quantification and inhalation cancer risk (ICR) assessment due to PM10- and PM2.5-bound PAHs has been carried out at six monitoring stations in a critically polluted Jharia coalfield/Dhanbad City. Identification of pollution sources at study area has been performed by using PCA statistical methods. Air quality index (AQI) and air quality health index (AQHI) were calculated based on the concentration levels of PM10...

We report on the case of a 25-year-old man with pituitary germinoma. The patient had noticed polydipsia, reduced sexual function, and loss of body hair. Laboratory investigations confirmed panhypopituitarism including diabetes insipidus. Magnetic resonance imaging of the brain showed a 14×8.4 mm enhancing lesion of the pituitary stalk and histopathology of the neurosurgical biopsy confirmed pituitary germinoma. The patient was treated with 3 cycles of chemotherapy, consisting of 150 mg/m(2) etoposide and 75 mg/m(2) cisplatin, with the administration of intrathecal 12...

BACKGROUND/AIM: Human papillomavirus type 16 (HPV16) induces various types of cancer in several locations. Microenvironmental microRNAs (miRNAs) such as miRNA-146a and miRNA-150 regulate cancer-associated inflammation and are involved in HPV-induced carcinogenesis. We studied the effects of celecoxib on the expression of these two miRNAs in HPV16-induced lesions. MATERIALS AND METHODS: Female transgenic (HPV16(+/-)) and wild-type (HPV16(-/-)) mice were administered 75 mg/kg/day celecoxib orally (treatment groups) or placebo (control groups) for four weeks...

Mucosa-associated lymphoid tissue (MALT) lymphoma is rarely observed in the gallbladder, and its diagnosis before surgery is difficult. This report describes a case of primary MALT lymphoma of the gallbladder in an 80-year-old man. Imaging studies revealed a protruding lesion on the inside of the gallbladder, which led us to diagnose gallbladder carcinoma prior to the patient undergoing extended cholecystectomy. Microscopic examination of the resected specimen of the gallbladder demonstrated lymphoid follicles with atypical lymphocytes and the formation of lymphoepithelial lesions...

8-Oxoguanine, a common mutagenic DNA lesion, generates G:C>T:A transversions via mispairing with adenine during DNA replication. When operating normally, the MUTYH DNA glycosylase prevents 8-oxoguanine-related mutagenesis by excising the incorporated adenine. Biallelic MUTYH mutations impair this enzymatic function and are associated with colorectal cancer (CRC) in MUTYH-Associated Polyposis (MAP) syndrome. Here, we perform whole-exome sequencing that reveals a modest mutator phenotype in MAP CRCs compared to sporadic CRC stem cell lines or bulk tumours...

Stroke mimics (SM) are non-vascular conditions that present with an acute neurological deficit simulating acute ischemic stroke and represent a significant percentage of all acute stroke hospital admissions. The most common clinical SM includes conversion/functional (psychiatric disorder); seizures and postictal paralysis; toxic-metabolic disturbances; brain tumours; infections, and migraine. Imaging is essential for SM recognition, being Diffusion weighted imaging (DWI), perfusion imaging and angiographic studies very useful...

BACKGROUND: Patients who have had inadequate response to tumour necrosis factor inhibitors have fewer treatment options and are generally more treatment refractory to subsequent therapeutic interventions than previously untreated patients. We report the efficacy and safety of ixekizumab, a monoclonal antibody that selectively targets interleukin-17A, in patients with active psoriatic arthritis and previous inadequate response to tumour necrosis factor inhibitors. METHODS: In this double-blind, multicentre, randomised, placebo-controlled, phase 3 study (SPIRIT-P2), patients were recruited from 109 centres across ten countries in Asia, Australia, Europe, and North America...

Objective: To investigate the potential dosimetric benefits of four-dimensional computed tomography (4DCT) compared to three-dimensional CT (3DCT) in the planning of radiotherapy for external-beam partial breast irradiation (EB-PBI). Methods: Three-DCT and 4DCT scan sets were acquired for 20 patients who underwent EB-PBI. For each patient a conventional 3D conformal plan (3D-CRT) was generated based on end-inhalation phase (EI). The treatment plan based on the 4DCT EI phase images was copied and applied to the end-exhalation phase (EE) and 3DCT images (defined as EB-PBI(EI), EB-PBI(EE), EB-PBI(3D), respectively)...

BACKGROUND: The risk of significant haemorrhage in pelvic exenterative surgery requiring sacrectomy has been well described. Patients requiring a sacrectomy above S3 are placed in the prone position, posing an increased challenge to gaining control of haemorrhage when it occurs. We describe a technique of pre-emptive control of the internal iliac vein and its three named tributaries to tame the pelvis prior to sacrectomy. METHODS: A retrospective, descriptive analysis was performed on a cohort of 25 consecutive patients operated on by one of the authors (AA E) between January 2005 and December 2010; all of whom underwent pre-emptive internal iliac vein triple tributary venous ligation, either unilaterally or bilaterally prior to sacrectomy above the level of S3...

Tumour heterogeneity poses a significant challenge for treatment stratification. The goals of this study were to quantify heterogeneity in hepatocellular carcinoma (HCC) using multiparametric magnetic resonance imaging (mpMRI), and to report preliminary data correlating quantitative MRI parameters with advanced histopathology and gene expression in a patient subset. Thirty-two HCC patients with 39 HCC lesions underwent mpMRI including diffusion-weighted imaging (DWI), blood-oxygenation-level-dependent (BOLD), tissue-oxygenation-level-dependent (TOLD) and dynamic contrast-enhanced (DCE)-MRI...

Until recently, the diagnosis of brain tumors was primarily based on microscopic examination of hematoxylin and eosin (H&E) stained tissue sections. The updated World Health Organization (WHO) classification of tumours of the central nervous system (CNS) incorporates genetic alterations into the classification system, with the goal of creating more homogenous disease categories with greater prognostic value. Hence, under the new classification system the diagnosis of diffuse gliomas incorporates the evaluation of mutations in the IDH1 and IDH2 genes and simultaneous deletion of chromosomes 1p and 19...

BACKGROUND: Outcomes for children with relapsed and refractory neuroblastoma are dismal. The combination of irinotecan and temozolomide has activity in these patients, and its acceptable toxicity profile makes it an excellent backbone for study of new agents. We aimed to test the addition of temsirolimus or dinutuximab to irinotecan-temozolomide in patients with relapsed or refractory neuroblastoma. METHODS: For this open-label, randomised, phase 2 selection design trial of the Children's Oncology Group (COG; ANBL1221), patients had to have histological verification of neuroblastoma or ganglioneuroblastoma at diagnosis or have tumour cells in bone marrow with increased urinary catecholamine concentrations at diagnosis...
