This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial tests whether doctors can safely use a special microscope called intravital microscopy during cancer surgery to look closely at the blood vessels that feed tumors. The procedure involves injecting a harmless dye called fluorescein into your bloodstream so the microscope can see the tiny blood vessels more clearly. Researchers hope this real-time imaging during surgery will help them understand how tumors grow and predict how well patients will recover.
Currently, doctors understand tumor blood vessels mainly by studying tissue samples after surgery. This new approach would let them observe living tumor blood vessels directly during the operation, which could reveal important information about the cancer that might help guide treatment decisions and improve survival outcomes.

Before your scheduled cancer surgery, you will have a skin test to confirm you are not allergic to the fluorescein dye. During your surgery, your surgeon will inject the dye into your vein and use the special microscope to examine your tumor's blood vessels for 1–2 minutes. After surgery, you will have a follow-up visit 2–3 weeks later to check your recovery.
