Protein expression of matriptase, c-Met, and E-cadherin determined by IHC. “+” indicates clear expression in the majority of cancer cells and “−“indicates no detectable staining above background (compared to serial sections incubated with a non-immune antibody). “S” indicates that the sample was acquired during surgery and “BX” indicates biopsy acquired sample.
