Overview
Neoplastic transformation is the most common complication of biliary cystadenoma. Biliary cystadenoma with mesenchymal stroma is associated with most favorable prognosis.
Complications
- In fact, even if the cystadenoma is a benign neoplasm, it has a high rate of recurrence and a potential for neoplastic transformation.
- Malignant transformation rate can be as high as 30%.[1]
Prognosis
Although biliary cystadenomas are benign tumors, they may recur after excision and have potential to develop into biliary cystadenocarcinomas.[2]
Biliary cystadenoma
- The prognosis of completely removed billiary cystadenomas is excellent, recurrence is rare.[3]
- Cystadenomas with mesenchymal stroma are considered premalignant with a good prognosis while those without are known to transform to malignancy more often with a poor prognosis.[4]
Biliary cystadenocarcinoma
- When treated with radical excision biliary cystadenocarcinomas have good prognosis, particularly those with mesenchymal stroma, unless the tumor invades the adjacent liver tissue or neighboring organs, or metastases are present.[3]
- Biliary cystadenocarcinomas in men which are not associated with mesenchymal stroma have worse prognosis, even after complete excision.[3]
