[A case of pancreatic solid-pseudopapillary tumor without cystic component in an elderly man].

We encountered a solid pseudopapillary tumor (SPT) without any cyst component in an elderly man. A literature survey of SPT without cystic component suggested that the size and vascularity of a tumor were related to lack of cystic component. The prognosis of this disease was comparatively good, but elderly or middle aged case and cases without capsule seem to have high malignant potential.

Gemcitabine suppresses malignant ascites of human pancreatic cancer: correlation with VEGF expression in ascites.

It has been reported that vascular endothelial growth factor (VEGF) is a potent angiogenic factor that also has the ability to increase vascular permeability. VEGF plays an important role in the development of malignant ascites in various cancers. Gemcitabine has been prescribed for patients with inoperable human pancreatic ductal carcinoma as a first-line chemotherapy.
