Glomus tumours are rare dermal tumours, which very seldom can be seen viscerally. The majority is benign small tumours of the skin. Malignancy has been reported in very few cases worldwide. The diagnosis is made clinically supported by MRI-scans and biopsy of the lesion. We present a case story of a 14-year-old boy, who had an infiltrative glomus tumour of the foot. The tumour met the criteria for malignancy and was operated radically by amputation of the forefoot. The post-operative period was uncomplicated and no metastases were observed neither clinically nor by PET-CT scans...

Gliomas are the most common lethal brain tumours and remain great heterogeneity in terms of histopathology and clinical outcomes. Among them, glioblastomas are the most aggressive tumours that lead to a median of less than one-year survival in patients. Despite the little improvement of in diagnosis and treatments for last decades, there is an urgent need for prognostic markers to distinguish high- and low-risk patients before treatment.Here, we generated a list of genes associated with glioblastoma progressions and then performed a comprehensive statistical modelling strategy to derive a 10-gene (GLO10) score from genome wide expression profiles of a large glioblastoma cohort (n=844)...

Circulating tumor cells (CTCs) have been recently accepted as prognostic markers in metastatic prostate cancer (PCa). However, very few studies have analyzed their role in early-stage PCa. The aim of this research is to study the value of CTCs at the moment of PCa diagnosis and to identify different subpopulations of CTCs. Patients with PSA value > 4 ng/ml and clinical suspicion of PCa were included. Samples were collected immediately before prostatic biopsy. CTCs were isolated by immunomagnetic technique using a multi-CK specific antibody...

Preoperative diagnosis of aortic sarcomas is often difficult. Herein, we describe a case of a 68-year-old man who had an aortic intimal sarcoma with aortic wall hypertrophy that masqueraded as a thrombosed aortic dissection or mural thrombus on computed tomography. Because of the sudden appearance and rapid growth of the tumour surrounding the left subclavian artery with precordial pain and haemosputum, left subclavian arterial rupture caused by aortic dissection was suspected, requiring emergent total arch replacement...

OBJECTIVES: Pulmonary artery sarcoma (PAS) is a rare and devastating disease. The diagnosis modality and optimal surgical strategy remain unclear. The aim of this study was to report our surgical experience in this disease. METHODS: Between 2000 and 2017, 13 patients underwent operations for PAS at our institution. Five patients underwent tumour resection alone, whereas the other 8 patients received pulmonary endarterectomy. The medical records were retrospectively reviewed to evaluate the clinical characteristics, operative findings and the postoperative outcomes...

OBJECTIVES: The median age at diagnosis of patients with pleural mesothelioma in the UK is 73 years. Recent series have shown the feasibility of extended pleurectomy decortication in the elderly, but with continuing debate about the efficacy of this treatment, we reviewed our experience to identify more detailed selection criteria. METHODS: We reviewed prospectively collected data on all patients from 1999 to 2016 undergoing extended pleurectomy decortication...

Colorectal cancer (CRC) is the third most common cancer and the fourth most common cause of cancer-related death worldwide. Tumour progression and development in CRC is a multi-step process involving a large number of genetic and epigenetic alterations. Previous studies indicated that abnormally expressed microRNAs play critical roles in CRC through regulation of oncogenic and tumour-suppressor genes. Hence, determination of the function of microRNAs may provide novel therapeutic targets for CRC diagnosis and treatments...

Glioblastoma (GBM), which is characterised by rapid growth, cellular heterogeneity, angiogenesis, extensive invasion, hypoxia and necrosis, is the most common histological subtype of glioma in adults. MicroRNA (miRNA) dysregulation is a common feature of human cancers, including GBM. Previous studies have suggested that miRNAs are a novel class of regulatory molecules in various human cancers. Therefore, miRNAs may be investigated as a novel candidate and screening tool in the clinical diagnosis, therapy and prognosis of GBM...

BACKGROUND: Pituitary tumours are common and easily treated by surgery or medical treatment in most cases. However, a small subset of pituitary tumours does not respond to standard medical treatment and presents with multiple local recurrences (aggressive pituitary tumours) and in rare occasion with metastases (pituitary carcinoma). The present ESE guideline aims to provide clinical guidance on diagnosis, treatment and follow-up in aggressive pituitary tumours and carcinomas. METHODS: We decided upfront, while acknowledging literature on aggressive pituitary tumours and carcinomas is scarce, to systematically review the literature according to the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system...

OBJECTIVE: Because melanoma patients are at high risk of further disease, we aimed to study their melanoma prevention behaviours. METHODS: In a large cohort of patients newly diagnosed with high-risk melanoma in Queensland, Australia, we assessed clustering of preventive behaviours using latent class analysis. We assessed associated factors with prevalence proportion ratios (PPRs) and 95% confidence intervals (CIs) estimated by Poisson regression, and also if preventive behaviour was associated with better tumour prognosis at diagnosis...

The existence of autoantibodies towards an individual's own proteins or nucleic acids has been established for more than 100years, and for a long period, these autoantibodies have been believed to be closely associated with autoimmune diseases. However, in recent years, researchers have become more interested in the role and application of autoantibodies in progression, diagnosis, treatment and prognosis of human malignant tumours. Over the past few decades, numerous epidemiological studies have shown that the risk of certain cancers is significantly altered (increased or decreased) in patients with autoimmune diseases, which suggests that autoantibodies may play either promoting or suppressing roles in cancer progression...

The diagnosis of glioblastoma remains one of the most dismal in medical practice, with current standard care only providing a median survival of 14.6 months. The need for new therapies is desperately clear. Components of the tumour microenvironment are demonstrating growing importance in the field, given they allow the tumour to utilise pathways involved in autoimmune prevention, something that enables the tumour's establishment and growth. As with many different cancers, the search for a new standard has progressed to the design of immunotherapies, which aim to counteract the immune changes within this microenvironment...

Glomus tumours are lesions of the glomus body. A solitary glomus tumour is a more common, characteristically painful lesion, frequently located under the nail, whereas multiple glomus tumours are a rare clinical and genetic entity. Multiple glomus tumours are rarely subungual and do not show preference for any particular region of the body. We report a rare case of painful multidigit subungual glomus tumours in both hands.A 34-year-old male patient complained of painful fingertips (right: thumb, index finger, long finger, and ring finger; left: thumb, long finger, ring finger, small finger) on both hands for more than 5 years...

In light of the high incidence and mortality rates of cancer, early and accurate diagnosis is an important priority for assigning optimal treatment for each individual with suspected illness. Biomarkers are crucial in the screening of patients with a high risk of developing cancer, diagnosing patients with suspicious tumours at the earliest possible stage, establishing an accurate prognosis, and predicting and monitoring the response to specific therapies. Epigenetic alterations are innovative biomarkers for cancer, due to their stability, frequency, and noninvasive accessibility in bodily fluids...

Acral melanoma is associated with outcomes which are more unfavourable than those of other melanoma subtypes, and acral melanoma has higher mortality. However, histological distinction of acral melanoma from acral naevi may be difficult. Fluorescence in situ hybridisation (FISH) targeting specific genes has been used as an ancillary method for differential diagnosis of melanocytic tumours, but most previous studies have focused on non-acral lesions which may have genetic alterations different from acral lesions...

An effective blood-based method for the diagnosis and prognosis of hepatocellular carcinoma (HCC) has not yet been developed. Circulating tumour DNA (ctDNA) carrying cancer-specific genetic and epigenetic aberrations may enable a noninvasive 'liquid biopsy' for diagnosis and monitoring of cancer. Here, we identified an HCC-specific methylation marker panel by comparing HCC tissue and normal blood leukocytes and showed that methylation profiles of HCC tumour DNA and matched plasma ctDNA are highly correlated...

BACKGROUND: Clinical and imaging manifestations are similar in pulmonary artery sarcomas (PAS) and thromboembolic diseases, especially central chronic pulmonary thromboembolism (CPTE). The feasibility of utilising clinical imaging tools such as computed tomography (CT) and magnetic resonance imaging (MRI) for differential diagnosis of PAS and CPTE has not been fully explored, especially MRI. METHODS: Patients with PAS (n=18) and central CPTE (n=20) treated at our hospital between January 2013 and September 2016 were identified retrospectively...

INTRODUCTION: Gastric lipomas are unusual benign lesions and account for less than 1% of all tumours of the stomach and 5% of all gastrointestinal lipomas (Thompson et al.2003; Fernandez et al. 1983 [1,2]). Although predominantly asymptomatic and indolent; they may present with gastric outlet obstruction and upper gastrointestinal (GI) bleeding owing to size and ulceration. Only a few cases have been reported, presenting large in size with massive GI bleeding (Alcalde Escribano et al...
