Early stage surgery for pancreatic head cancer is very successful 5-year survival is around 5%-10%, which is mainly evaluated and judged from whether the surgery is thorough, whether there are complications after surgery and the nature of malignancy of the patient. Pancreatic head cancer is pathologically mostly adenocarcinoma with a large amount of fibrous tissue in the interstitium. Pancreatic head cancer is also pathologically divided into subtypes such as mucinous adenocarcinoma, adenosquamous carcinoma and pleomorphic carcinoma; in addition to pancreatic ductal cell carcinoma, pancreatic cancer actually includes adenoalveolar cell carcinoma, pancreatic embryonic cell carcinoma, small cell carcinoma and other rare pathological types. The survival time of different types of pancreatic head cancer is different. The malignant degree of pancreatic head cancer is very poor, and the mortality rate is very high after effective treatment, therefore, it is necessary to do a good job of physical examination, so as to achieve “early detection, early diagnosis and early treatment”.
