In a recent article published in Science,Sharma et *** the essential role of saposins in cross-presentation of tumor membraneassociated antigens by dendritic cells(DC)to CD8^(+)T cells.1 However,antigen cross-presentation,which is fundamental in cancer cell elimination,is hindered in tumor DC by hyperglycosylation of the common saposin precursor prosaposin(pSAP)leading to impaired T cell tumor immunity-yet,the potential of recombinant pSAP to re-establish T cell responses may offer a novel way to counteract immune evasion in a therapeutic approach.

To the Editor: As we all know, even with the current advancements regarding novel chemotherapy regimens, patients affected by pancreatic cancer(PC) have an extremely dismal prognosis(5-year survival rate 12% for all stages in the National Cancer Institute SEER database). Among the patients undergoing surgical treatment, the prognosis is mostly affected by recurrence. PC after surgery has mainly four patterns of recurrence, isolated or variously associated with each other: local, lymph nodal, peritoneal or distant(liver, lung, other sites).
