What is acinar cell carcinoma of the pancreas?
What is acinar cell carcinoma of the pancreas?
Pancreatic acinar cell carcinoma is a rare neoplasm and has been considered a cancer with poor prognosis due low resectability, high recurrence rate and frequent metastases but acinar cell carcinoma is a more indolent disease than pancreatic ductal adenocarcinoma.
What causes acinic cell carcinoma?
Acinic cell carcinoma is more prevalent in women than in men. The exact cause of salivary gland cancers, including acinic cell carcinoma, is unknown; however, research suggests that possible causes of the disease may be previous exposure to radiation, wood dust inhalation, and a family history of salivary cancers.
What is Acinic?
Acinic cell carcinoma (ACC) is a low-grade malignant salivary neoplasm that constitutes approximately 17% of primary salivary gland malignancies. In the head and neck region, the parotid gland is the predominant site of origin and women are usually more frequently diagnosed than men.
What is the function of acinar cells?
The acinar cell is the workhorse of the exocrine pancreas—its primary responsibility is the production, storage and regulated secretion of the large amounts of enzymes necessary for the proper digestion and absorption of food.
What is a acinar cell tumor?
Acinar cell carcinoma of the pancreas, also acinar cell carcinoma, is a rare malignant exocrine tumour of the pancreas. It represents 5% of all exocrine tumours of the pancreas, making it the second most common type of pancreatic cancer. It is abbreviated ACC. It typically has a guarded prognosis.
Where in the pancreas are acinar cells?
duodenum
The exocrine cells (acinar cells) of the pancreas produce and transport chemicals that will exit the body through the digestive system. The chemicals that the exocrine cells produce are called enzymes. They are secreted in the duodenum where they assist in the digestion of food.
What do the pancreatic acinar cells secrete?
Pancreatic acinar cells secrete fluid and digestive enzymes.
What kind of cancer is acinar cell carcinoma of pancreas?
Acinar Cell Carcinoma of Pancreas is a rare, malignant cancer of the acinar cells of the pancreas. It typically occurs in elderly men. It may not cause any signs and symptoms initially.
Which is a rare neoplasm of the pancreas?
Abstract. Acinar cell carcinomas (ACCs) of the pancreas are rare pancreatic neoplasms accounting for about 1–2% of pancreatic tumors in adults and about 15% in pediatric subjects. They show different clinical symptoms at presentation, different morphological features, different outcomes, and different molecular alterations.
Which is better, adenocarcinoma or acinar cell carcinoma?
Pancreatic acinar cell carcinoma is a rare tumour, accounting for only about 1 % of all pancreatic tumours. The long-term survival for patients with acinar cell carcinoma is significantly better than the long-term survival of patients with pancreatic adenocarcinoma.
What are the risk factors for pancreatic carcinoma?
The specific risk factors for Acinar Cell Carcinoma of Pancreas are unknown or unidentified. However, the general risk factors for pancreatic tumors/cancers include: Advancing age: Pancreatic cancer may develop in individuals of all ages, but is seldom diagnosed in individuals younger than 55 years.
