ObjectiveTo summarize the individualized diagnosis and treatment experience in a patient with primary pancreatic diffuse large B-cell lymphoma.MethodsBy muti-disciplinary term (MDT) model, a patient with primary pancreatic diffuse large B-cell lymphoma admitted in the People’s Hospital of Chishui in Dec. 2016 was discussed. The diagnosis, perioperative period management, and operation scheme were carried out by the MDT.ResultsThe patient’s general condition was good. After multidisciplinary discussion in the Department of Radiology, Oncology, Interventional, and Hepatobiliary and Pancreatic Surgery, the patient was considered to have surgical indications. After thorough communication with the patient and family, the patient was selected for surgical resection. The whole operation lasted for 5 hours, and the intraoperative blood loss was about 300 mL. The operation was successfully completed and no complications such as pancreatic fistula occurred after operation. Liquid drainage tube was drawn out at 10 days after opertion, and pancreatic tube stent and T tube were retained. The patient discharged on 13 days after surgery. Subsequently, the patient underwent adjuvant chemotherapy. At present, the patient has been followed up for 1 year, no signs of tumor recurrence and metastasis, and continued follow-up.ConclusionsPrimary pancreatic diffuse large B-cell lymphoma is rare and has a poor prognosis. The main treatment is mutli-mode treatment based on surgical resection combined with chemotherapy.
