What is primary pancreatic cancer

First, you must pay attention to primary pancreatic cancer. The early symptoms of pancreatic cancer include: 1. Loss of appetite and emaciation. About 10% of the first symptoms are loss of appetite, and some of the first symptoms are emaciation. In fact, this is no longer an early sign. Some people think that anorexia, nausea and vomiting, change of stool habits, and emaciation are the four early symptoms of pancreatic body and tail cancer. 2. Upper abdominal pain and indescribable discomfort, stuffy feeling, sometimes light, sometimes heavy, sometimes no, generally more obvious at night.

Second, primary pancreatic cancer can occur in any part of the pancreas, but the head is the most common, accounting for about 3 / 4; while the body and tail of the pancreas account for only 1 / 4. Carcinoma of the head of the pancreas usually originates from pancreatic duct epithelium, while carcinoma of the body and tail of the pancreas often originates from acini. Adenocarcinoma was the most common type of carcinoma in the ampulla, followed by papillary carcinoma and mucinous carcinoma.

Third, the metastasis of primary pancreatic cancer includes: (1) direct invasion to surrounding tissues, including the lower end of the common bile duct, duodenum, stomach and transverse colon; (2) lymph node metastasis. Pancreatic head cancer usually metastasizes to the lymph node group under the pylorus, while pancreatic body and tail cancer mainly metastases to the lymph node group of the pancreas and spleen, as well as mesentery and para aortic lymph nodes; ③ Hematogenous metastases are mostly transferred to the liver through the portal vein, and then from the liver to the lung through the superior and inferior vena cava; ④ spreading along the nerve sheath, it often causes persistent back pain due to the infiltration of lymphatic vessels around the retroperitoneal nerve; ⑤ peritoneal implantation, including omentum and omentum.
