Pancreatic plasmacytoid cystadenoma is benign in the vast majority of cases, with a very low tendency of malignant transformation, it mainly occurs in the body tail of the pancreas, with no obvious clinical symptoms, if the cystadenoma is relatively large, it can be surgically resected, and if it is a benign tumor, it doesn’t need to be chemotherapeutically treated after the operation. However, pancreatic plasmacytoid cystadenoma still can not rule out the risk of cancer combined with carcinoma, so it is recommended to cooperate with doctors to do further examination, if cancer occurs on the basis of cystic tumor, there is a certain chance of recurrence after the surgery, it is necessary to go to the hospital for rechecking regularly, and some patients who are combined with pancreatic cancer may need to take chemotherapy after the surgery. After surgery for pancreatic plasma cystadenoma, you should cooperate with your doctor to take further treatment or review.
