The sound of melanoma can help doctors find cancer
Date:2/23/2010

COLUMBIA, Mo. Knowing the stage of a patient's melanoma is important when choosing the best course of treatment. When the cancer has progressed to the lymph nodes, a more aggressive treatment is needed. Examining an entire lymph node for cancer takes much effort and time; a new technique might help make the process more efficient. University of Missouri researchers in the Christopher S. Bond Life Sciences Center are studying how photoacoustics, or a laser-induced ultrasound, could help scientists locate the general area of the lymph node where melanoma cells could be residing. This new technology could help doctors identify the stage of melanoma with more accuracy.

"This method can be used to determine if the cancer has spread from stage 2, where the melanoma is still just in the skin lesion, to stage 3, where the melanoma has spread to the lymph nodes," said John Viator, assistant professor in the Department of Biological Engineering and Department of Dermatology . "If the cancer is still at stage 2, a simple procedure can remove that lesion. If the cancer has progressed from the initial skin lesion into the lymphatic region and possibly the bloodstream, doctors have to make serious decisions about patient care. The cancer may have possibly spread to other organs, such as the liver, lungs or brain."

Currently, pathologists must perform several specific and detailed tests to determine if there is cancer in the lymph nodes. This new technology could make the search less time-consuming by identifying a general area of the lymph node that might contain cancer.

"It's very similar to identifying a prize inside a cake," Viator said. "Instead of looking through the entire cake, we can use our ultrasound to pinpoint a slice or two that might contain the 'prize.' In the case of the lymph nodes, when you get a signal, this alerts the pathologist that this is an area of the node that might contain cancer cells. At that point, a pathologis
