Causes And Treatment Of Pancreatic Cancer - 1385 Words

INTRODUCTION Pancreatic cancer is the fourth leading cause of cancer death Worldwide. It is the eighth most common cause of death from cancer in both individuals. Higher incidence is noted as thirteen because of the very poor prognosis. Less than 5% of all patients are still alive only for 5 years after initial diagnosis. It is rarely detected in the early stages and conventional cancer treatment failed due to high resistance to chemotherapy. Pancreatic cancer develops gradually in a series of steps known as pancreatic intraepithelial neoplasia. This is the most prominent stage of cancer. During the early steps, slight changes are seen in a small number of genes. In the later steps, there are abnormalities in several genes and the duct cells become dysfunctional. The most common DNA changes in these conditions affects the KRAS oncogene. KRAS is the mutated gene in PDAC and this gene is said to drive cancer development and progression. This was observed in mouse as human pancreatic tissue is not available for biopsy and animal tissue have the ease of genetic manipulation and cost effective. Inflammation is the main phenomenon that is said to promote the formation of premalignant lesions and accelerates pancreatic cancer development. PDAC is caused by immune dysfunction that is contributed by immunosuppressive cell types such as TAM’s, MDSC’s, tumor promoting immune cells and abnormal inflammatory cells. CURRENT APPROACH The role of the immune response in the developmentShow MoreRelatedCauses And Treatments Of Pancreatic Cancer832 Words   |  4 Pages23 October 2015 Pancreatic Cancer Cancer is a number one cause of death in both men and women around the world. Pancreatic cancer holds a survival rate of just 6% of people surviving within five years after being diagnosed, and there is still no definite cure to the deadly diagnosis. A majority of pancreatic cancer patients fight a long, tiring battle that they usually cannot defeat. Although, this cancer may be very deadly there are many early diagnosis procedures and treatments that can be performedRead MoreCauses And Treatment Of Pancreatic Cancer2511 Words   |  11 PagesAbstract: Pancreatic cancer is one of the deadliest cancers with the 4th highest mortality amongst all cancers. Causes of such high mortality include rapid proliferation, late diagnosis and lack of treatment options available. New therapy aiming to decrease mortality in pancreatic cancer patients aim to work with oncolytic viruses to halt the cell cycle pathway. One of the more promising mutations is the E1A-CR2-deleted AD5 mutants however there are many different types of mutated viruses aimed atRead MoreCauses And Treatment Of Pancreatic Cancer1573 Words   |  7 PagesPancreatic Cancer What exactly is the pancreas it is an organ that makes insulin and enzymes for digestion.

Pancreatic cancer affects approximately 28,000 Americans each year, or five out of 100,000 people (Mayo Clinic, 1998). According to physicians at Johns Hopkins Medical Institute, pancreatic cancer is the challenge of the twenty-first century. So, where exactly is the pancreas located in our bodies, and what does it do? The pancreas is a gland found behind the stomachRead MoreDifferent Treatment Options For Cancer1606 Words   |  7 PagesThe different treatment options available for cancer vary depending on which cancer has been diagnosed. Pancreatic cancer which affects the pancreas and surrounding lymph nodes and tissue, is the 4th leading cause of cancer-related deaths in the United States (pancreatic.org) and when compared to the other leading cancers in mortality rates, 94% of pancreatic cancer patients will die within five years of diagnoses and only 7% will surviv e more than five years.

The pancreas is both an endocrine and exocrine gland. Cancer of the exocrine pancreas is more common than cancerof the endocrine pancreas. Pancreaticcancer is the fourth leading cause of cancer related deaths among men and women. Pancreatic cancer remains both a challenge to diagnose and even a greater challenge to treatRead MorePancreatic Cancer : A Form Of Cancer1273 Words   |  6 PagesPancreatic Cancer is a form of cancer in which malignant cancer cells invade the pancreas, a gland that produces digestive fluid and hormones that regulate blood sugar. There are two types of pancreatic cancer: exocrine and endocrine cancer. The malignant cells can infiltrate either the exocrine pancreatic cells, responsible for digestive fluid, or the endocrine pancreatic cells, responsible for regulatory hormones. If the pancreas’ exocrine cells are affected metabolic functions are slowed or stoppedRead MoreEssay on Analysis and Description of Pancreatic Cancer1734 Words   |  7 PagesWhat is Pancreatic Cancer? Pancreatic Cancer is cancer of an organ in the human body called the pancreas, which is located behind the lower part of the stomach. The function of this organ is to secrete certain essential enzymes to digest food and also secrete hormones to metabolize sugars such as insulin and glucagon (Mayoclinic). People get pancreatic cancer when the cells of the pancreas develop genetic mutations; and these can form in both the exocrine and endocrine cells of the pancreas, butRead MoreThe Problem Of Pancreas Adenocarcinoma With Complete Encasement Of The Superior Mesenteric Artery And Vein1238 Words   |  5 PagesProblem Pancreas adenocarcinoma with complete encasement of the superior mesenteric artery and vein.
