A Case of Small Pancreatic Cancer with Intra-pancreatic Metastasis Diagnosed by Endoscopic Ultrasound.
Summary of "A Case of Small Pancreatic Cancer with Intra-pancreatic Metastasis Diagnosed by Endoscopic Ultrasound."
Introduction: The usefulness of endoscopic ultrasound (EUS) in the diagnosis of small pancreatic cancer is widely accepted. We experienced a small, 8 mm, pancreatic cancer with intra-pancreatic metastasis of 2 mm revealed by EUS. The patient was a 71-year-old female with a small low echoic tumor observed by abdominal ultrasonography. She was referred to our hospital for further investigation. She complained of mild abdominal pain. She had a past history of myoma uteri. Ultrasonography showed a 10 mm low echoic mass in the body of the pancreas, but it was difficult to make a distinction between a solid mass and a cystic lesion. No tumor was shown by CT or MRI. EUS was performed, and showed a solid low echoic tumor of 8 mm and a low echoic mass of 2 mm in a diameter near the tumor. An ERCP study was performed, but the cytology of the normal main pancreatic duct was shown to be benign. We diagnosed the patient with pancreatic cancer, and surgery was performed. A pathological examination revealed a 10 mm invasive ductal carcinoma and intra-pancreatic metastasis.

Medical and Biotech [MESH] Definitions
A 36-amino acid pancreatic hormone that is secreted mainly by endocrine cells found at the periphery of the ISLETS OF LANGERHANS and adjacent to cells containing SOMATOSTATIN and GLUCAGON. Pancreatic polypeptide (PP), when administered peripherally, can suppress gastric secretion, gastric emptying, pancreatic enzyme secretion, and appetite. A lack of pancreatic polypeptide (PP) has been associated with OBESITY in rats and mice.
Extracts prepared from pancreatic tissue that may contain the pancreatic enzymes or other specific uncharacterized factors or proteins with specific activities. PANCREATIN is a specific extract containing digestive enzymes and used to treat pancreatic insufficiency.
Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).
Pancreatic Stellate Cells
Star-shaped, myofibroblast-like cells located in the periacinar, perivascular, and periductal regions of the EXOCRINE PANCREAS. They play a key role in the pathobiology of FIBROSIS; PANCREATITIS; and PANCREATIC CANCER.
Trypsin Inhibitor, Kazal Pancreatic
A pancreatic trypsin inhibitor common to all mammals. It is secreted with the zymogens into the pancreatic juice. It is a protein composed of 56 amino acid residues and is different in amino acid composition and physiological activity from the Kunitz bovine pancreatic trypsin inhibitor (APROTININ).
Pancreatic cancer is known to metastasize rapidly. Liver and peritoneum are the most common sites of metastases in pancreatic cancer, followed by lungs, bones and brain. Less common sites of metastase...
Lymph node (LN) metastasis is one of the most important risk factors for the prognosis of pancreatic cancer. This study aimed to identify novel LN metastasis-associated markers and therapeutic targets...
We report a case of a 50-year-old male with isolated pancreatic metastasis from hepatocellular carcinoma (HCC), in which chemical shift magnetic resonance imaging detected the presence of fat, and whi...
A20 protein plays essential roles in tumorigenesis, but its value for diagnosis of pancreatic cancer remains unclear. Our aim was to determine whether A20 is a potential biomarker for the diagnosis of...
Pancreatic cancer is critical for developed countries, where its rate of diagnosis has been increasing steadily annually. In the past decade, the advances of pancreatic cancer research have not contri...
We are undertaking a study of patients with gastric or pancreatic cancer. A common place for cancer to return after surgery for gastric or pancreatic cancer is the inside lining of the abd...
The purpose of this study is to find the best and most sensitive screening modality (CT, MRI, EUS)for very small pre-cancerous pancreatic lesions and to treat these small lesions before th...
The purpose of this study is to investigate the safety and possible efficacy of the use of pentamidine in the treatment of pancreatic cancer metastasis in subjects receiving standard thera...
Pancreatic cancer often spreads through local invasion into local structures, including fat, blood vessels, nerves, and nearby organs (stomach, duodenum, spleen, bile duct). Local microsco...
The purpose of the study is to collect pancreatic tissue, blood and urine from adults to study pancreatic abnormalities.
