PURPOSE: Histologic findings in 51 pancreata resected from patients with a strong family history of pancreatic cancer were compared with the findings in 40 pancreata resected from patients with sporadic pancreatic cancer. None of the patients in the familial group had a known inherited syndrome other than familial pancreatic cancer. EXPERIMENTAL DESIGN: Precursor lesions, including pancreatic i...

A 59-year-old male patient with jaundice was referred to our hospital because of mass lesions in the pancreatic head and tail. An immunological examination revealed an elevated serum IgG4 level. Computed tomography showed two clear boundary mass lesions in the pancreatic head and tail. Magnetic resonance imaging showed that the mass lesions exhibited low intensity on T1-weighted images and iso-...

As cross-sectional imaging has become more common, there has been a marked increase in the incidental detection of cystic pancreatic lesions. It is estimated that more than a third of these are found in asymptomatic patients. Although knowledge of the natural history of cystic lesions is incomplete at this time, it is known that some cystic pancreatic lesions, including pseudocysts and serous c...

Endoscopic ultrasound-fine needle aspiration (EUS-FNA) is the current primary technique for evaluating pancreatic lesions, with increasing use of fine biopsy (FNB) to obtain larger tissue sample. In this study, we aimed determine diagnostic yield FNA and FNB lesions performed at St George Hospital in a two year period from 2020 2021 inclusive. There were 92 69 performed. The was 86% 87%. This r...

Since its introduction, contrast-enhanced ultrasonography (CEUS) has significantly extended the value of ultrasonography (US). CEUS can be used to more accurately determine pancreatic lesions compared to conventional US or to characterize lesions already detectable by US. Thus, CEUS can aid in the differential diagnosis of pancreatic tumors. Using US contrast media, it is possible to visually d...

Pancreatic cancer is still a dismal disease. The high mortality rate is mainly caused by the lack of highly sensitive and specific diagnostic tools, and most of the patients are diagnosed in an advanced and incurable stage. Knowledge about precursor lesions for pancreatic cancer has grown significantly over the last decade, and nowadays we know that mainly three lesions (PanIN, and IPMN, MCN) a...

UNLABELLED The AIM of our study was to evaluate the accuracy of CEUS in the characterization of pancreatic solid lesions, considering cross sectional imaging techniques (CE-CT/MRI) as the "gold standard" methods. MATERIAL AND METHODS We performed a retrospective, monocentric study that included 91 solid pancreatic lesions which were evaluated by CEUS and by a second-line contrast imaging tech...

Technical advances in cross-sectional imaging have led to the discovery of incidental cystic pancreatic lesions in the oncology and non-oncology population that in the past remained undetected. These lesions have created a diagnostic and management dilemma for both clinicians and radiologists: should these lesions be ignored, watched, aspirated, or removed? In this review, recommendations conce...

Hedgehog signaling has been implicated in the development of several human cancers, including small cell lung carcinomas, medulloblastomas, basal cell carcinomas, and digestive tract tumors. Elevated levels of pathway components are observed in pancreatic ductal adenocarcinoma (PDAC) precursor lesions, and these levels increase further as lesions progress to more advanced stages. Yet the mechan...

OBJECTIVE: To present computed tomography findings observed in four patients submitted to radical nephrectomy for renal cell carcinoma who developed pancreatic metastases afterwards. MATERIALS AND METHODS: The four patients underwent radical nephrectomy for stage T1 (n=2) and stage T3a (n=2) renal cell carcinoma. The mean interval between nephrectomy and detection of pancreatic metastases was e...
