Prognostic Value Of PET/CT Determined Sarcopenia in Patients with Resected Ampullary Carcinoma

Objectives: Our aim is to investigate the prognostic value and effect on chemotherapy toxicity of pre-treatment sarcopenia determined with positron emission tomography/computerized tomography(PET/CT) in patients with ampullary carcinoma. Methods: Characteristics of patients retrieved retrospectively. Skeletal muscle area(SMA) measurement of the muscle at L3 vertebra level was evaluated for each patient from their PET/CT scan taken at the time of diagnosis. The sex-specific cut-off levels for determining sarcopenia were
