Diagnosis of Ampullary Cancer

Endoscopic papillectomy has been reported to be the treatment of choice in patients with ampullary adenoma. For ampullary cancer, pancreaticoduodenectomy is the standard treatment. Since neither lymphatic permeation, vascular invasion, nor lymph node metastasis is observed in patients with ampullary cancer limited to the mucosa, endoscopic resection of such tumors can be justified if no ductal ...

Commentary Systems Epidemiology in Cancer

Prospective studies in cancer epidemiology have conserved their study design over the last decades. In this context, current epidemiologic studies investigating gene-environment interactions are based on biobank for the analysis of genetic variation and biomarkers, using notified cancer as outcome. These studies result from the use of high-throughput technologies rather than from the developmen...

Ampullary cancer in chemical workers.

Among biliary tract tumours, ampullary cancer is regarded as having a favourable prognosis because the early onset of symptoms, low grade histopathology, and late and infrequent metastases allow the possibility of surgical cure; nevertheless, high operative morta...

Surgical Management of Ampullary Somatostatinoma

Introduction Somatostatinomas of the ampulla are rare neuroendocrine tumours with limited studies in the literature. These are often associated with familial genetic predisposition e.g. NF 1 and Von Hippel-Lindau Syndrome. Histology commonly shows classical features such as Psammoma bodies. The classical presentation with inhibitory syndrome is rare, but ampullary mass effects can cause an earl...
