Evaluation of tumor mass at fluorescent microscope and Fluorescence guided surgery in the xenograft mouse model of fibrosarcoma. a Representative picture of the evaluation of tumor mass under MacroFluo. b-e, Representative pictures of fluorescence guided surgery (FGS) before and after tumors removal with bright light surgery (BLS). In one mouse (e) is clearly evident the presence of residual cells infiltrating into the quadriceps muscle after the tumor removal by BLS while in another mouse (d) FGS indicates a precise resection of tumor mass without any residual cells in the surgical wound
