Summary
Brief summary (as posted)
Splenomegaly is common in advanced pancreatic ductal adenocarcinoma (PDAC). The spleen is an important source of immune suppressive cells and phagocytic cells and may mediate the accumulation of liposomal drugs and immunosuppression. In this study, spleen irradiation (SI) will be added to standard chemotherapy.
