Background: The prognostic effect of resection margin status following pancreatoduodenectomy for pancreatic ductal adenocarcinoma (PDAC) remains controversial, even with the implementation of standardized pathological assessment. We therefore investigated the impact of resection margin (RM) status and RM distance in curative resected PDAC on overall survival (OS), disease-free survival (DFS) and recurrence.

Method: 108 patients were retrieved from a prospectively maintained database of a certified pancreatic cancer center.

The macroscopic and microscopic assessments of pancreatic cancer resection specimens belong to the standard repertoire of any department of pathology. In recent years standards have been developed regarding both macroscopic and microscopic assessments, which are laid down in international and national guidelines and classifications and are regularly updated. In this way the reporting of results and interdisciplinary communication are facilitated.

Purpose: Intraductal papillary neoplasms of the biliary tract (IPNB) are rare tumors originating from the bile duct epithelium. Metastatic disease of IPNB is extremely rare and only reported in a small number of cases worldwide. Due to this limitation in number, the treatment of IPNB mainly relies on retrospective case series.

Since the implementation of a nationwide screening colonoscopy the incidence of colorectal adenocarcinoma is decreasing, while the amount of early endoscopically resectable tumours is increasing. Similarly malignant tumors of the upper gastrointestinal tract are diagnosed and resected endoscopically more often. In part, this also depends on improvements in technology.

Background: Although laparoscopic cholecystectomy is recommended as standard treatment for acute cholecystitis, in 10-30 % a conversion to open cholecystectomy is required. Among some surgeons, this is still perceived as a "complication." The aim of our study was to define characteristics and outcome of patients with acute cholecystitis undergoing conversion cholecystectomy.

Background & Aims: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in combination with cytopathology is the optimal method for diagnosis and staging of pancreatic ductal adenocarcinoma (PDAC) and other pancreatic lesions. Its clinical utility, however, can be limited by high rates of indeterminate or false-negative results. We aimed to develop and validate a microRNA (miRNA)-based test to improve preoperative detection of PDAC.

Background: Colorectal cancer is one of the most frequently observed neoplasms in the world. It develops from intraepithelial neoplasia of the colorectal mucosa, and these precursor lesions are also known as adenoma. As the precursor lesion is known and can be detected easily, efficient screening strategies are available for a reliable prevention of colorectal adenocarcinoma, e.

The MRE11/RAD50/NIBRIN complex, a protein complex that repairs DNA double-strand breaks, could serve as an early marker for new lesions in pancreatic cancer. We determined the expression of MRE11, RAD50 and NIBRIN, and their possible prognostic value regarding survival. Forty-one patients with ductal adenocarcinoma of the pancreas were included.

Background: Hard pancreas is welcome by surgeons performing resective pancreatic surgery, because it is believed to offer better suture holding capacity (SHC), thus decreasing the risk for a postoperative leak. However, neither the actual SHC of pancreatic tissue in humans nor its determinants have been studied.

Methods: We directly measured SHC for polydioxanone 5-0 suture and tissue hardness at the pancreatic isthmus in 53 human pancreata using a dynamometer and a durometer.

Background: Endoscopic polypectomy significantly reduces the incidence of colorectal cancer, but recurrence rates are high, especially for adenomas with advanced histology. The present guidelines recommend re-colonoscopy 3 to 5 years later. Due to limited resources, more precise predictions of adenoma recurrence are required.

Background: Osteonecrosis of the jaw (ONJ) is defined by areas of tissue breakdown and exposure of bone in the maxillofacial region that fail to heal within 8 weeks after identification by a health provider in a patient who has not received radiation of the jaws. The disease affects the quality of life and produces significant morbidity in afflicted patients. ONJ is correlated with such risk factors as treatment with bisphosphonates, dental extraction-related trauma, chemotherapy, corticosteroids, renal osteodystrophy and infections.

Article Synopsis
  • Scientists are trying to find better ways to detect cancer early to help people live longer and healthier lives.
  • They studied special tiny RNA molecules in the blood of mice with pancreatic cancer and found a new one called RNU2-1 that could help identify cancer better than the previously looked at miR-1246.
  • The new test using RNU2-1 was really good at finding cancer in patients, and it could even detect it at an earlier stage in some cases!

MicroRNAs (miRNAs) are small non-coding RNAs that are involved in different biological processes by suppressing target gene expression. Altered expression of miR-30a-5p has been reported in colon carcinoma. To elucidate its potential biological role in colon cancer, miR-30a-5p was overexpressed via a lentiviral vector system in two different colon cancer cell lines.

CCR7 expression on tumor cells promotes lymphatic spread in several malignant tumors. However, a comprehensive characterization of the CCL19/CCL21-CCR7 axis in pancreatic ductal adenocarcinoma (PDAC), which is known for its high rates of lymph-node metastases, is still lacking. CCR7 mRNA and CCR7 protein were found to be expressed in spheroid cultures of all six examined PDAC cell lines.
