Forty to fifty percent of colorectal cancer (CRC) patients develop colorectal liver metastases (CLM) that are either synchronous or metachronous in presentation. Clarifying whether there is a biological difference between the two groups of liver metastases or their primaries could have important clinical implications. A systematic review was performed using(More)
Neoadjuvant imatinib for gastrointestinal stromal tumours (GISTs) is increasingly used nowadays. As oesophagectomy is associated with high morbidity and mortality, a preoperative downsizing of an oesophageal GIST to limit the extent of resection would be ideal. Because these tumours are rare and neoadjuvant treatment with imatinib is recent, there is(More)
Bevacizumab is a humanized monoclonal antibody targeting vascular endothelial growth factor (VEGF), often used in combinational chemotherapy regimens for the treatment of patients with colorectal liver metastases. However adverse events have been attributed to the use of bevacizumab including gastrointestinal perforations, thrombotic events, hypertension,(More)
BACKGROUND Renal cell carcinoma accounts for 90% of renal neoplasms and metastatic disease is common. One third of newly diagnosed cases will have synchronous metastases at diagnosis and further 25-50 % will develop metachronous disease. CASE PRESENTATION This study presents two new cases of gallbladder metastasis from renal cell carcinoma (RCC) from our(More)
Pancreatic cancer is extremely resistant to chemo-and radiation-therapies due to its inherent genetic instability, the local immunosuppressive microenvironment and the remarkable desmoplastic stromal changes which characterize this cancer. Therefore, there is an urgent need for improvement on standard current therapeutic options. Immunotherapies aimed at(More)
There has, in recent years, been a paradigm shift in our understanding of the role of the immune system in the development of cancers. Immune dysregulation, manifesting as chronic inflammation, not only facilitates the growth and spread of tumors but prevents the host from mounting effective immune defenses against it. Many attempts are being made to(More)
INTRODUCTION Gastrointestinal stromal tumours (GISTs) are thought to derive from or differentiate towards the interstitial cells of Cajal (ICC) as most demonstrate a similar immunoprofile: CD117+, CD34+ and DOG1+. ICC hyperplasia refers to KIT-expressing microscopic spindle cell proliferations involving the myenteric plexus. CASE REPORT 74 year-old male(More)
BACKGROUND Disease assessment based on measurements of size and anatomic involvement have historically been central to surgical strategy. We propose this to be an outdated concept, which should be replaced by a deeper understanding of tumor biology and careful treatment planning. Report of case: A 34-year-old male was diagnosed with a Siewert Type 3 locally(More)
We present the case of a 67-year-old male patient with a past history of previously resected T3 right adrenocortical carcinoma and T3N1 signet ring cell adenocarcinoma of the stomach who presented with recurrence of gastric cancer in the form of a large solitary mass in the right abdomen. He was treated with ECX (epirubicin, cisplatin and capecitabine)(More)
Duodenal metastasis from renal cell carcinoma is rare, and even rarer is a massive gastrointestinal bleeding from such tumours. Coeliac occlusive disease, although rarely symptomatic, can lead to ischaemic changes with anastomotic dehiscence and leaks when a patient undergoes pancreatoduodenectomy. A 41-year-old man with known metastasis to the adrenal(More)
