Pancreas cancer is sown scatteredly and shifting _'s general knowledge
Pancreas head cancer is not totally identical with the body of pancreas, transformation route of the end cancer, head cancer of the pancreas is often infringed to the person in over-all charge of gallbladder, duodenum, stomach and arteria coeliaca, mainly the lymph node is shifted to the lymph node around five arteries around the artery through the mesenterium for its lymphocytic transformation route. The body of pancreas, tail cancer are often shifted toward abdominal cavity's neural clump and spinal along the neurilemma, or along places such as shifting on the pancreas and liver door lymph node of lymphatic vessel,etc.. (1992) such as Kayahara Expand the operation sample which radically treats the skill patient after studying a group of 44 pancreas head cancers, 3l example (70% among them )There are lymph nodes that are shifted, the lymph node already shifted includes: 8th group (total artery of liver is dry) , the 12th next group (the underpart in liver duodenum ligament) , the 13th group (behind pancreas head) , the 14th group (mesenterium root) , the 17th group (before pancreas head) . Second stop lymph node is the 9th group (around arteria coeliaca) respectively , the 11th group (spleen artery is dry) , 12 go group (the intersection of liver and the intersection of duodenum and the intersection of ligament and inner top) , the 16th group (around belly aorta) And the 18th group (under pancreas head) Lymphocytic, its lymphocytic transformation route mainly forms and infringes to the lymph node around the aorta around the artery through the mesenterium.
In addition, the transformation of pancreas cancer has the following characteristics:
1. Shifting early pancreas cancer because grows very fast, in addition pancreas blood vessel, lymphatic vessel are abundant, and it is shifted that the pancreas own bag membrane is incomplete, often early.
2. It is that pancreas cancer is different from another biological characteristic of other digestive tract tumours to shift and shift along the nerve along nerve supply, (1988) such as Kayahara Tumour of 34 cases of pancreas cancer patient of network analysis shifts the route. Find that there is cancerous swelling of the patients of 97% that is shifted along nerve supply, is higher than shifting along the lymphocytic way (76%) .
