EGFR and breast cancer: Railkar et al. [27] described a targeted form of photo-therapy called photoimmunotherapy (PIT) that targets EGFR-expressing BC in their study, and found that anti-EGFR antibody panitumumab (Pan) IR700-induced PIT selectively killed EGFR-expressing BC cells in vitro and in vivo, and therefore warrants further therapeutic study in orthotopic xenografts of BC and ultimately in patients.
