Ampulla of Vater metastases from renal cell carcinoma are rare. The time between detection of the primary tumour and its metastasis may extend to years. Management should be aggressive, since the prognosis of renal cell carcinoma is unpredictable and curative surgery of metastases may extend patient survival and even lead to definite cure.

Pancreatic tumors are usually diagnosed at an advanced stage in the progression of the disease, thus reducing the survival chances of the patients. Non-invasive early detection would greatly enhance therapy and survival rates. Toward this aim, we investigated in a pilot study the power of methylation changes in whole blood as predictive markers for the detection of pancreatic tumors.

Radiofrequency ablation is one of the alternatives in the management of liver tumors, especially in patients who are not candidates for surgery. The aim of this article is to review applicability of radiofrequency ablation achieving complete tumor destruction, utility of imaging techniques for patients' follow-up, indications for local ablative procedures, procedure-associated morbidity and mortality, and long-term results in patients with different tumors. The success of local thermal ablation consists in creating adequate volumes of tissue destruction with adequate "clear margin," depending on improved delivery of radiofrequency energy and modulated tissue biophysiology.

Article Synopsis
  • The study compares transcatheter arterial embolization (TAE) and open surgery for treating bleeding duodenal ulcers after unsuccessful endoscopic therapy, showing TAE as a potential alternative with lower mortality in high-risk patients.
  • Analysis involved 24 patients who underwent TAE and 50 who had surgery, measuring factors like mortality, complications, and length of hospital stay across both groups.
  • Results indicated no significant difference in overall complications, but TAE patients had a lower mortality rate among high-risk individuals while exhibiting a higher re-bleeding rate, suggesting further trials are needed for low-risk assessments.

Background/aims: Hyperthermia induced apoptosis may lead to tumor cell death thus expanding the volume of non-viable tissue and warrant a "safety margin" of at least 10mm to exclude the possibility of tumor recurrence. We carried out an experimental study to investigate the cellular injury produced by radiofrequency ablation in the area surrounding the ablated tissue and to describe early apoptotic processes in the transition zone following radiofrequency ablation procedure in a porcine liver model.

Methodology: Nine anesthetized pigs underwent laparotomy and local thermal ablation of the liver parenchyma.
