As this large surgical procedure induces muscle protein loss, a preserved anabolic response to nutrition is warranted for optimal recovery. It is unclear whether the presence of early stage cancer negatively affects the protein metabolic response to major surgery as this would mandate perioperative nutritional support.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>In nine women with early stage (Stage II) breast malignancy and nine healthy women with a genetic predisposition to breast cancer undergoing the same large surgical procedure, we examined whether surgery influences the catabolic response to overnight fasting and the anabolic response to nutrition differently. Prior to and within 24\u2009h after combined bilateral mastectomy and reconstruction surgery, whole body protein synthesis and breakdown rates were assessed after overnight fasting and after meal intake by stable isotope methodology to enable the calculation of net protein catabolism in the post\u2010absorptive state and net protein anabolic response to a meal.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Major surgery resulted in an up\u2010regulation of post\u2010absorptive protein synthesis and breakdown rates (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u20090.001) and lower net protein catabolism (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u20090.05) and was associated with insulin resistance and increased systemic inflammation (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u20090.01).
