Can the sentinel lymph node technique affect decisions to offer internal mammary chain irradiation?
SLN detection by peritumoral injection, combined with the systematic removal of the internal mammary SLN, enabled the involvement of this region to be found in a nonnegligible number of patients. Such information should make it possible to personalize treatment for patients with stage cT1 mammary cancer and thereby avoid needless internal mammary radiation therapy in a large number of patients (93.4% in our study).
Both tumor cell and tumor vasculature B7-H3 expression convey important information to predict ccRCC outcomes. Collectively, our past and present studies pertaining to B7-H ligand expression indicate that ccRCC may use redundant mechanisms to compromise host antitumoral immunity. Future studies will focus on the effect of combined B7-H ligand expression in RCC.
