New imaging technique visualizes cancer during surgery
Date:9/19/2011

Ovarian cancer is one of the most frequent forms of cancer that affect women. As tumors can initially grow unchecked in the abdomen without causing any major symptoms, patients are usually diagnosed at an advanced stage and have to undergo surgery plus chemotherapy. During the operation, surgeons attempt to remove all tumor deposits as this leads to improved patient prognosis. To do this, however, they primarily have to rely on visual inspection and palpation - an enormous challenge especially in the case of small tumor nests or remaining tumor borders after the primary tumor excision.

Yet surgeons could now be getting support from a new multispectral fluorescence imaging system developed by a team of researchers in Munich, headed by Vasilis Ntziachristos, Professor of Biological Imaging. A study carried out on nine patients with ovarian cancer has shown that the new system can be used to localize cancer cells during surgery. Before the operation, the patients were injected with folic acid chemically coupled to a green fluorescent dye. Most ovarian tumors have a protein molecule on their surface that bonds with folic acid and transports it inside the cell. This protein is known as the folate receptor alpha. During abdominal surgery, the surgeon can then shine a special laser light onto the patient's ovaries, causing the green-labeled folic acid inside the cancer cells to emit light. Healthy tissue remains dark.

The fluorescent cancer cells, however, cannot be detected by the naked eye. Three cameras, mounted on a pivoting support arm over the operating table, detect optical and fluorescent signals at multiple spectral bands and then correct for light variations due to illumination and tissue discolorations in order to provide truly accurate fluorescence images that can be simultaneously displayed with corresponding color images on monitors in the operating room. The surgeon can thus check whether all the cancer cells have been removed by
