Osteosarcoma (OSA) is the most common malignant bone cancer in children and dogs. The therapeutic protocols adopted for dogs and humans are very similar, involving surgical options such as amputation. Besides surgical options, radiotherapy and chemotherapy also are adopted. However, hematologic, gastrointestinal and renal toxicity may occur because of chemotherapy treatments. Recent study clearly showed that mesenchymal stem cells (MSCs) combined with recombinant human bone morphogenetic protein (rhBMP-2) may be associated with decreases of the tumorigenic potential of canine OSA...

A 68-year-old woman with known metastatic renal cell carcinoma presented with an acutely swollen right leg. In between the two sessions of palliative radiotherapy to the right hip, she also had right hip modified Harrington procedure for tumour resection with hip replacement. Initial clinical evaluation raised the suspicion of right leg deep vein thrombosis (DVT). However, DVT was excluded and further investigations revealed stenosis of the right external and common iliac veins, likely secondary to radiotherapy...

Zhonghua Sun, Dongting Liu
The aim of this systematic review is to analyse current literature related to the clinical value of three-dimensional (3D) printed models in renal disease. A literature search of PubMed and Scopus databases was performed to identify studies reporting the clinical application and usefulness of 3D printed models in renal disease. Fifteen studies were found to meet the selection criteria and were included in the analysis. Eight of them provided quantitative assessments with five studies focusing on dimensional accuracy of 3D printed models in replicating renal anatomy and tumour, and on measuring tumour volume between 3D printed models and original source images and surgical specimens, with mean difference less than 10%...

CLINICAL ISSUE: Renal lesions are detected earlier, often as a result of ultrasound examinations. However, the imaging-based differential diagnosis of different tumour entities remains challenging STANDARD RADIOLOGICAL METHODS: All renal tumours >1 cm should be evaluated for malignancy by computed tomography (CT) or magnetic resonance imaging (MRI). If an angiomyolipoma diagnosis cannot be established with imaging, further diagnostics are appropriate or if malignant progression is suspected, then multidisciplinary discussion for TNM-staging based uro-oncologic therapy is usual...

Introduction: Hemangioblastomas [75% sporadic, 25% with Von Hippel Lindau (VHL) disease] are highly vascular, benign lesions. The surgical nuances, management, and complication avoidance in brain-stem hemangioblastomas (BHs) have been studied. Material and Methods: Over 18 years, 27(mean age: 29 years; range 15-60 years) consecutive cases of BH underwent microsurgical excision. All patients were assessed clinico-radiologically for neurological deficits and screened for VHL disease...

Renal cell carcinoma is the most common renal tumour in adult that often metastasises to the lung, liver or bone. Head and neck lesions are uncommon with no early warning signs and presents with overt metastases at primary presentation in 25%-30% of reported cases. The incidence of haemangiomas that suggest malignancy are similar to that of bone metastasis. Calvarial haemangiomas usually present as asymptomatic and discovered incidentally on imaging or postmortem examination. We report a case where an initial diagnosis of benign tumour of the skull was made based on clinical presentation and calvarial haemangioma on CT head but was confirmed as metastatic clear cell carcinoma of the kidney after histopathological results...

Extract: Pancreatic neuroendocrine tumours (pNETs) are an established feature of von Hippel-Lindau disease (VHL), occurring in up to 17% of mutation carriers (Libutti et al. 2000; Blansfield et al. 2007; Erlic et al. 2010; Igarashi et al. 2014). The natural history of VHL-pNETs is poorly characterised with metastatic disease occurring in up to 25% of affected individuals (Erlic et al. 2010). Management of this unique pNET subgroup is complicated by the potential for multifocal and metachronous disease as well as extra-pancreatic VHL-related neoplasms (e...

BACKGROUND AND AIMS: Increasing evidence has shown the critical role of long non-coding RNA cytoskeleton regulator (CYTOR) in cancers. The expression of CYTOR is reported to be up-regulated in many kinds of cancers, such as gastric cancer, hepatocellular carcinoma, colon cancer, lung adenocarcinoma, oesophageal squamous cell carcinoma and renal cell carcinoma. Here, we summarized related studies and performed a meta-analysis to investigate the prognostic value of CYTOR in multiple cancers...

Background & objectives: The determination of cystatin C (cysC) may be helpful in diagnosis and monitoring of cancer because the pathogenesis of cancer is linked with an increased activity of cysteine peptidases (cathepsins) and a decrease of cysC concentration. This study was aimed to examine the utility of cysC as a marker of bladder cancer (BCa) to be used in the diagnosis. Methods: This study was conducted with 90 patients with BCa and 27 healthy people...

Background: Positive nodal status (pN1) is an independent predictor of survival in renal cell carcinoma (RCC) patients. However, no study to date has tested whether the location of lymph node (LN) metastases does affect oncologic outcomes in a population submitted to radical nephrectomy (RN) and extended lymph node dissection (eLND). Objective: To describe nodal disease dissemination in clear cell RCC (ccRCC) patients and to assess the effect of the anatomical sites and the number of nodal areas affected on cancer specific mortality (CSM)...

BACKGROUND: Choriocarcinoma is a rare malignant germ-cell tumour, most commonly found in adult women. It infrequently presents as spontaneous renal haemorrhage (SRH). Genital malformation and SRH secondary to choriocarcinoma has previously been only reported in females. We present what we believe to be the first case of a male patient with genital malformation (hypospadias and cryptorchidism) and SRH at presentation of choriocarcinoma. CASE PRESENTATION: A 25-year-old man presented to the department with intense pain in the right flank region and lower back...

Context: Circulating Rare Cells (CRC) are non-haematological cells circulating in blood. They include Circulating Cancer Cells (CCC) and cells with uncertain malignant features (CRC-UMF) according to cytomorphology. Clear cell renal cell carcinomas frequently bear a mutated Von Hippel-Lindau (VHL) gene. Aim: To match blind genetic analysis of CRC and tumor samples with CRC cytopathological diagnosis. Results: 29/30 patients harboured CRC (20 harboured CCC, 29 CRC-UMF) and 25/29 patients carried VHL mutations in their tumour...

CONTEXT: Most practice decisions relevant to preserving kidney function in patients managed surgically for kidney tumours are driven by observational studies. A wide range of outcome measures are used in these studies, which reduces comparability and increases the risk of reporting bias. OBJECTIVE: To comprehensively and succinctly describe the outcomes used to evaluate kidney function in studies evaluating surgical management of kidney tumours. EVIDENCE ACQUISITION: Electronic search of the PubMed database was conducted to identify studies with at least one measure of kidney function in patients managed surgically for kidney tumours, published between January 2000 and September 2017...

BACKGROUND/AIM: Gastric cancer (GC) radiotherapy involves irradiation of large tumour volumes located in the proximities of critical structures. The advantageous dose distributions produced by scanned-proton beams could reduce the irradiated volumes of the organs at risk (OARs). However, treatment-induced side-effects may still appear. The aim of this study was to estimate the normal tissue complication probability (NTCP) following proton therapy of GC, compared to photon radiotherapy...

PURPOSE: Following curative treatment for localised renal cell carcinoma (RCC), up to 30% of patients develop tumour recurrence. Prognostic scores are essential to guide individualised surveillance protocols, patient counselling and potentially in the future to guide adjuvant therapy. In metastatic RCC, prognostic scores are routinely used for treatment selection in clinical practice as well as in all major trials. METHODS: We performed a literature review on the current evidence based on prognostic factors and models for localised and metastatic RCC...

Angiomyolipoma is a benign mesenchymal tumour, which rarely involve inferior vena cava (IVC) and pulmonary arteries. Here we reported a 41-year-old man, who presented symptoms of chronic pulmonary embolism. After multiple images evaluation, a large tumour with the same properties as the pulmonary embolism was found in the right kidney. One-staged surgery to remove both pulmonary embolism and right kidney was performed. Histological study showed the tumour and embolism as angiomyolipoma. The present study reported a rare case with renal angiomyolipoma and both IVC and pulmonary arteries involvements, which provided a good example for differential diagnosis in the emergency department and treating a rare type of chronic pulmonary embolism after renal angiomyolipoma...
