PET imaging prior to surgery helps stage a patient's disease by providing functional images of tumors throughout the body, especially areas where cancer has spread, otherwise known as metastasis. Few studies have been able to pin down exactly what impact preoperative PET has on clinical decision-making and resulting treatment. Preliminary review of the data from this long-term, observational study of an entire community of veterans was inconclusive about the utility of PET, but after a more thorough statistical analysis accounting for selection bias and other confounding factors, the researchers were able to conclude that PET imaging eliminated approximately half of unnecessary surgeries.
"It has become standard of care for lung cancer patients to receive preoperative PET imaging," said Steven Zeliadt, PhD, lead author of the study conducted at VA Puget Sound Health Care System and associate professor for the University of Washington in Seattle, Wash. "The prevailing evidence reinforces the general understanding within the medical community that PET is very useful for identifying occult metastasis and that it helps get the right people to surgery while avoiding unnecessary surgeries for those who would not benefit."
