Pancreatic cancer is one of the most lethal types of malignant tumours, commonly diagnosed at an advanced stage. The only curative treatment for this fatal disease is surgery and early diagnosis is the key to a better outcome and prognosis. In this case report we present a 57-year-old woman presenting to the emergency room with abdominal pain and weight loss. Computer Tomography (CT) imaging showed a rupture of the main pancreatic duct and a peri-pancreatic fluid collection with no evidence of a pancreatic mass...

Feline injection-site sarcomas are malignant skin tumours with a high local recurrence rate, ranging from 14% to 28%. The treatment of feline injection-site sarcomas includes radical surgery, radiotherapy and/or chemotherapy. In our previous study it has been demonstrated that doxorubicin conjugated to glutathione-stabilized gold nanoparticles (Au-GSH-Dox) has higher cytotoxic effects than free doxorubicin for feline fibrosarcoma cell lines with high glycoprotein P activity (FFS1, FFS3). The aim of the present study was to assess the effectiveness of intratumoural injection of Au-GSH-Dox on the growth of tumours from the FFS1 and FFS3 cell lines on chick embryo chorioallantoic membrane...

Cancers are the major cause of death worldwide. Chemotherapy using cytotoxic drugs and targeted therapy is required when surgery is difficult, ineffective, or impossible. We previously synthesized the novel synthetic 1-benzylindole derivative 21-900 and found that it inhibits histone deacetylase (HDAC) activities and tubulin assembly. Here we tested its effects on the human leukaemia cell lines HL-60 and MOLT-4 in vitro and in vivo. We found that its potent cytotoxic effects were mediated through cell cycle arrest at the G2/M phase, which increased the population of sub-G1 cells, leading to apoptosis...

AIM: Anastomotic leakage (AL) following abdominal surgery is a critical determinant of postoperative recovery, of which the aetiology is largely unknown. Interestingly, interventions aimed at reducing the inflammatory response and postoperative ileus (POI) have an unexpected effect on AL. The aim of this study was to investigate the relation of POI with inflammation and AL after colorectal resection. METHOD: A post-hoc analysis of a prospective RCT, in which patients underwent a colorectal resection was performed...

BACKGROUND: Renal cell carcinoma (RCC) is a highly vascularised tumour, where anti-angiogenic treatment with multi-tyrosine-kinase-inhibitor, is used for first-line treatment of metastatic disease. Variations in vascular characteristics are likely to contribute to variations in intrinsic aggressiveness of the disease. Emerging studies are identifying perivascular status, including perivascular PDGFR-β, as a determinant of prognosis in other tumour types. METHODS: This work explored the impact on prognosis of vascular characteristics in RCC through analyses of a population-based collection of tumours from surgery-alone-treated patients...

BACKGROUND: Pancreatic cancer has a 5-year survival rate of only 5-7%. Difficulties in detecting pancreatic cancer at early stages results in the high mortality and substantiates the need for additional diagnostic tools. Surgery is the only curative treatment and unfortunately only possible in localized tumours. A diagnostic biomarker for pancreatic cancer will have a major impact on patient survival by facilitating early detection and the possibility for curative treatment. DNA promoter hypermethylation is a mechanism of early carcinogenesis, which can cause inactivation of tumour suppressor genes...

Venous thromboembolism (VTE) is a significant health problem in the general population but especially in cancer patients. In this review, we discuss the epidemiology and burden of the disease, the pathophysiology of cancer-associated VTE, and the clinical treatment options for both primary prevention and acute treatment. Overall, the development of VTE in cancer patients is related to increases in morbidity, mortality, and medical costs. However, the incidence of cancer-associated VTE varies due to patient-related factors (e...

A 37-year-old male presented with a traumatic injury to the scrotal region necessitating emergency surgery. Evacuation of a haematoma and bilateral orchidectomy were performed. A left sided nonseminomatous germ cell tumour (NSGCT), predominantly yolk sac, was identified. Microscopic margins were positive for tumour. Initial tumour markers revealed an AFP of 22,854 ng/mL, HCG of <1 mIU/mL, and LDH of 463 IU/L. Eight weeks after surgery, AFP levels remained elevated at 11,646 ng/mL. Computed tomography (CT) scanning demonstrated left inguinal adenopathy, 1...

INTRODUCTION: The most common cause of adult Giant Hydronephrosis (GH) is congenital Uretero-Pelvic Junction (UPJ) obstruction. Conventional imaging modalities, like Intravenous Urography (IVU) and Computed Tomography Urography (CTU) and radionuclide renal scan can be fallacious. Serum carbohydrate antigen 19-9 (CA19-9) is a useful tumour marker for gastrointestinal and pancreatic cancer. Only a few studies and case reports have shown raised serum levels due to benign hydronephrosis and GH...

The prediction of lymph node metastasis using clinic-pathological data and molecular information from endometrial cancers lacks accuracy and is therefore currently not routinely used in patient management. Consequently, although only a small percentage of patients with endometrial cancers suffer from metastasis, the majority undergo radical surgery including removal of pelvic lymph nodes. Upon analysis of publically available data and published research, we compiled a list of 60 proteins having the potential to display differential abundance between primary endometrial cancers with versus those without lymph node metastasis...

Malignant mesothelioma (MM) continues to be a disease with poor prognosis and limited treatment options. Calretinin and caveolin-1 expression by tumour in MM have recently been described to be associated with tumour histology, differentiation and consequently survival. In a large, well annotated cohort, we studied both of these biomarkers and explored their association with clinicopathological parameters and survival. A retrospective search of patients with MM who underwent surgery at the Austin Hospital in Melbourne, Australia, was conducted...

Glioblastoma has been reckoned as the prime cause of death due to brain tumours, being most invasive and lethal. Available treatment options, i.e. surgery, radiotherapy, chemotherapy and targeted therapies are not effective in improving prognosis, so an alternate therapy is insistent. Plant based drugs are efficient due to their synergistic action, multi-targeted approach and least side effects. Present investigation reports the strong anti-tumorous potential of Nardostachys jatamansi rhizome extract (NJRE) on U87 MG glioblastoma cells...

BACKGROUND: Micrometastasis (MM) in colorectal cancer (CRC) is not considered in tumour-node-metastasis (TNM) staging currently and also the prognostic significance of these occult tumoural cells is not proven yet. This study was designed to find whether MM to bone marrow (BM) and/or liver cause upstaging of the tumour according to conventional staging system and if it may alter the survival rate. METHODS: Thirty-eight CRC patients who were candidates of surgical procedure were enrolled in our cross-sectional study...

BACKGROUND: Classical Meigs' syndrome consists of the triad of an ovarian fibroma, ascites and pleural effusion. A characteristic of the syndrome is that the excess fluid is resorbed after surgical resection of the tumour. CASE DESCRIPTION: A 49-year-old woman was admitted to accident and emergency department in a neglected, cachectic and hypothermic condition. A CT scan revealed an ovarian tumour, ascites and a right-sided pleural effusion. The level of the tumour marker CA-125 was also greatly elevated...

Identifying circulating tumour DNA (ctDNA) for monitoring of cancer therapy is dependent on the development of readily designed, sensitive cancer-specific DNA markers. Genomic rearrangements that are present in the vast majority of cancers provide such markers.Tumour DNA isolated from two fresh-frozen lung tumours underwent whole genome sequencing. Genomic rearrangements were detected using a new computational algorithm, GRIDSS. Four genomic rearrangements from each tumour were chosen for further study using rearrangement-specific primers...
