PS01.170: IMPACT OF MUSCLE MASS, NUTRITIONAL STATUS AND MUSCLE STRENGTH ON OUTCOMES FOLLOWING SURGERY FOR ESOPHAGEAL CANCER

Abstract

Abstract Background Muscle function loss and loss of skeletal muscle have been associated with worse outcomes following surgery for malignancies of gastrointestinal origin. The influence on post-operative outcomes and survival after esophageal surgery remains unclear. Primary objectives of this study were to evaluate the incidence of sarcopenia and malnutrition and to evaluate the influence of skeletal muscle surface area and muscle strength on postoperative outcomes and overall survival in esophageal cancer patients. Methods A retrospective cohort study from a prospective database was conducted in patients with resectable esophageal cancer who underwent curative-intent treatment between January 2011 and January 2016. Skeletal muscle surface area was calculated with CT scans at L3 level and corrected for height and weight before start of treatment and in the interval between neoadjuvant treatment and surgery. Muscle strength was evaluated with various tests on muscle functions and lung function tests. Nutritional status was evaluated using BMI. Results 273 Patients were included. There were 4 patients with sarcopenia before neoadjuvant therapy and only one patient with sarcopenia after completion of neoadjuvant therapy. Median skeletal muscle surface area was 78cm2/m2 for men and 61cm2/m2 for woman. Table 1 shows skeletal muscle surface area, muscle strength and BMI in relation to no, minor or major complications. Muscle strength and nutritional status did not have a significant influence on postoperative complications and overall survival. Conclusion Sarcopenia did not occur frequently in this cohort with potentially curable esophageal cancer patients. Muscle function, skeletal muscle index and BMI did not statistically influence post-operative complications or survival. Disclosure All authors have declared no conflicts of interest.
