Renal cell carcinoma accounts for 2%-3% of all malignancies in adults. It spreads via direct extension, lymphatic route as well as haematogenous route. Lymph nodes, lungs, bone, liver and brain are the usual sites for its metastatic spread. In the presence of limited metastatic disease with potentially resectable metastases, surgery offers the best chances of cure. In the present case, we describe a case of renal cell carcinoma with a solitary metastasis to the sigmoid mesentery in a patient with Von Hippel-Lindau syndrome...

While the current standard first-line treatment for advanced renal cell carcinoma (RCC) is sunitinib, patients inevitably develop resistance to this drug. However, the rapid development of nanotechnology has provided emerging techniques for the treatment of advanced tumours, including RCC. In our previous research, cuprous oxide nanoparticles (CONPs) showed ideal anti-tumour effects and low systemic toxicity. While many inorganic nanomedicines, including CONPs, have similar pharmacological effects, their detailed mechanisms remain unknown...

PURPOSE: Grade 3 NENs are aggressive tumours with poor prognosis. PRRT+/- radiosensitising chemotherapy is a potential treatment for disease with high somatostatin receptor (SSTR) expression without spatially discordant FDG-avid disease. We retrospectively evaluated the efficacy of PRRT in G3 NEN. METHODS: Kaplan-Meier estimation was used to determine progression-free survival (PFS) and overall survival (OS) defined from start of PRRT. Subgroup analysis was performed for patients with Ki-67 ≤ 55% and >55%...

Synovial sarcoma is a soft tissue neoplasm with clearly defined histologic, immunohistochemical and molecular features. These tumours usually arise in the extremities of young adults. Their occurrence in the kidney is extremely rare. A 25-year-old pregnant lady in her first trimester was incidentally found to have a left renal mass on perinatal ultrasonography. MRI showed a well encapsulated, heterointense mass replacing the left kidney. Following medical termination of her pregnancy, a radical nephrectomy was performed...

Large renal tumours are not uncommon in developing countries. Enhancing renal tumours are considered to be malignant unless proved otherwise and radical surgical resection remains the mainstay of treatment of such tumours. A giant renal tumour, especially on right side, poses a big challenge for the operating team and requires a thoracoabdominal approach for successful excision. We report successful removal of the largest documented Multilocular Cystic Nephroma (MLCN, 5.5 kg) from a 28-year-old female who presented with right abdomen lump since two years...

A 47-year-old male presented with haematuria and flank pain for two weeks. Ultrasonography and renal scan revealed a poorly functioning left kidney with multiple calculi. Simple nephrectomy was performed and the specimen revealed a mass in his renal pelvis which showed both carcinomatous and sarcomatous components on microscopy. The sarcomatous component consisted of diffuse pleomorphic osteoblasts with intervening lacy osteoid, giving an osteosarcoma-like appearance. These areas of tumour were strongly positive for vimentin and osteopontin...

PURPOSE: Anti-angiogenic and mammalian target of rapamycin inhibitors have shown efficacy in solid tumours. Reported combination of both drugs was deemed to be too toxic. Due to a potential favourable safety profile of axitinib (AX), a phase I study combining everolimus (EV) and AX for solid tumours was explored. EXPERIMENTAL DESIGN: Patients (pts) with advanced cancers were enrolled in an escalation phase I study to investigate the safety of the combination. Pharmacokinetic profile and functional vascular imaging were performed...

The tetraspanin KAI1/CD82 was identified as a tumor metastasis suppressor that downregulated in various malignant cell types. However, the function of CD82 and its underlying anti-metastasis role in renal cell carcinoma (RCC) is still unraveled. Here, we investigated the expression of CD82 in RCC and explored its regulatory mechanism in RCC cell lines. We found that CD82 was down-regulated in RCC tissues and cells and its expression was significantly associated with histological grade(p=0.041), tumour stage (p=0...

BACKGROUND: TargomiRs are minicells (EnGeneIC Dream Vectors) loaded with miR-16-based mimic microRNA (miRNA) and targeted to EGFR that are designed to counteract the loss of the miR-15 and miR-16 family miRNAs, which is associated with unsuppressed tumour growth in preclinical models of malignant pleural mesothelioma. We aimed to assess the safety, optimal dosing, and activity of TargomiRs in patients with malignant pleural mesothelioma. METHODS: In this first-in-man, open-label, dose-escalation phase 1 trial at three major cancer centres in Sydney (NSW, Australia), we recruited adults (aged ≥18 years) with a confirmed diagnosis of malignant pleural mesothelioma, measurable disease, radiological signs of progression after previous chemotherapy, Eastern Cooperative Oncology Group performance status of 0 or 1, life expectancy of 3 months or more, immunohistochemical evidence of tumour EGFR expression, and adequate bone marrow, liver, and renal function...

The quantity of the preserved parenchyma after partial nephrectomy is the result of interplay among various factors: the unmodifiable preoperative quality of the renal parenchyma and some technical modifiable aspects. Among the modifiable factors able to influence the quantity, the suture technique has gained paramount importance. Indeed, nowadays there is a consensus suggesting that one of the main predictors of the ultimate renal function is the minimal parenchymal volume loss: this is the sum of the healthy parenchyma excised with the tumour and the portion of the parenchyma devascularised by the renorrhaphy...

Renal angiomyoadenomatous tumour is a newly described rare neoplasm. This tumour is characterised microscopically by admixture of three components- epithelial cells arranged in tubules and nests, angiomyomatous stroma and capillary sized interconnecting vascular channels in close association with the epithelial cell clusters. Microscopically it has wide range of differential diagnoses which include mixed epithelial and stromal tumour of kidney, angiomyolipoma and clear cell renal cell carcinoma with angiomyolipomatous/angiomyoadenomatous areas...

Renal cell carcinoma (RCC) may metastasize to almost any organ, but bowel metastases are highly unusual. A 75-year-old man presented with symptoms and signs of severe anaemia due to bowel bleeding and abdominal pain due to recurrent bowel intussusception. The patient underwent surgery and was identified to have intraluminal metastases from metastatic RCC. To the best of our knowledge, few cases of metastases from RCC manifesting as synchronous intraluminal polypoid tumours have been described in the literature...

A 64-year-old Japanese man with renal cell carcinoma (RCC) and tumour thrombus in the inferior vena cava was treated with sunitinib. Two weeks after treatment, he was hospitalised for disturbance of consciousness. Laboratory tests revealed high-grade hypoglycaemia, hyponatraemia, liver dysfunction and thrombocytopaenia with disseminated intravascular coagulation. Sunitinib was discontinued and the patient recovered after a protracted platelet transfusion. At 5 months after treatment, CT revealed that the tumour thrombus had disappeared and other lesions had regressed...

Cystic nephroma is a rare and benign renal tumour of unknown origin, usually diagnosed in the first years of childhood or during adult life. To our knowledge, there are no records in the literature of this particular tumour being descried prenatally. We present a case of a fetus diagnosed with cystic nephroma on 16 weeks of gestation. The renal tumour was evaluated by prenatal ultrasound, post mortem with 7T magnetic resonance imaging, and conventional autopsy.

Karin Ried, Peter Eng, Avni Sali
Background: Circulating-Tumour-Cells (CTC) provide a blood biomarker for early carcinogenesis, cancer progression and treatment effectiveness. An increase in CTCs is associated with cancer progression, a CTC decrease with cancer containment or remission. Several technologies have been developed to identify CTC, including the validated Isolation-by-Size-of-Epithelial-Tumour (ISET, Rarecells) technology, combining blood filtration and microscopy using standard histo-pathological criteria. Methods: This observational study compared CTC count to cancer status and cancer risk, by monitoring treatment effectiveness in cancer patients and by screening for CTC in asymptomatic patients with risk factors, including family history of cancer...
