Study finds outcomes of high-risk cancer operations in 80-year-olds worse tha...( CHICAGO (December 18 2007) New rese...),Health

CHICAGO (December 18, 2007) New research published in the December issue of The Journal of the American College of Surgeons shows that outcomes of high-risk cancer operations in 80-year-olds are considerably worse than reported in case studies and published survival statistics, which may lead to unrealistic expectations about the safety of these operations in the elderly. With this limited information, elderly patients and their physicians may have difficulty accurately assessing the risks and benefits of major cancer operations.

An increasing number of the very elderly are undergoing major cancer operations as the population ages. Between 1994 and 2003, total surgical discharges after lung, esophageal and pancreatic resection in patients aged 80 years and older increased by 76 percent, and this new number is expected to increase by more than 50 percent by 2020. Current information about outcomes in octogenarians undergoing cancer operations is limited largely to case studies from tertiary care centers, which perform high volumes of these procedures and thus have superior outcomes. For lung, esophageal and pancreatic resection, single-center studies report operative mortality rates between 3 and 4 percent for the very elderly.

"Our study showed that there is a need to improve patient outcomes in the elderly nationwide," said lead investigator of the study Emily Finlayson, MD, MS, assistant professor of surgery, University of Michigan. "Furthermore, it provides a wake up call that the realistic risks and long-term benefits of major cancer operations differ for older patients when compared to their younger counterparts. This difference is essential to consider when surgeons and their older patients are making decisions about whether or not to have this type of surgery, particularly if the patient has other existing medical issues as this further affects the risk-benefit equation."
