Pelvic cancer refers to malignant tumors occurring in biliopancreatic potbellies, and its etiology is still unclear, which is related to healthy cell gene mutation, cholelithiasis, biliary tract infections, etc. Clinical manifestations are jaundice, lack of appetite, and unexplained emaciation. Patients with early-stage jugular cancer without metastasis can be treated with standard pancreaticoduodenectomy, pylorus-preserving pancreaticoduodenectomy and other surgeries after evaluation by doctors, and radiotherapy can be used after surgery to assist the treatment if necessary. Chemotherapy drugs such as 5-fluorouracil, mitomycin and cytarabine can also be used for chemotherapy after surgery. In general, early pot belly cancer patients have better prognosis and five-year survival rate can reach 40%~60% after timely standardized treatment, but if patients do not have timely treatment, complications such as upper gastrointestinal bleeding may occur, which can be life-threatening in serious cases. It is recommended that patients maintain a good state of mind and actively cooperate with the doctor’s treatment.
