Using fluorescence intensity as a readout for cetuximab-IRDye800CW accumulation within the tissues, the MFI was correlated with biological characteristics of the tumor that might also influence antibody (peri-)tumoral distribution and binding into the tumor including cytokeratin (tumor density), EGFR expression, Factor VIII (vascular density) and Ki67 (proliferation) for each dose group (Table 1). The gene discussed is EGFR; the disease is neoplasm.
