3 Method of Concealment Blinding/Masking Primary Outcome Outcome Timepoints Primary objective 1) To evaluate the ability of FDG PET/CT in predicting histopathological response after neo-adjuvant chemotherapy in patients with adenocarcinoma of the gastroesophageal junction. 2 years Secondary Outcome Outcome Timepoints 1.To assess if reduction in metabolism on FDG PET predict disease free survival (DFS) 2. To compare morphological response with histopathological response. 2 years Target Sample Size Phase of Trial Date of First Enrollment () Date of First Enrollment (Global) Estimated Duration of Trial Recruitment Status of Trial (Global) Recruitment Status of Trial () Publication Details Total Sample Size=75 Sample Size from =75 N/A 01/08/2014 No Date Specified Years=2 Months=0 Days=0 Completed Brief Summary Patients : Will be Published in Index Journal The study will include all operated patients of esophageal adenocarcinoma who have undergone pre and post neo-adjuvant chemotherapy FDG PET/CT studies from October 2010 to Jan 2013 Routine investigations for diagnosis and staging will be performed in all patients. Investigations done will include upper gastrointestinal endoscopy and biopsy, PET-CECT and EUS. PET/CT findings and histological findings will be entered into a database. Metabolic response using FDG PET and histopathological response will be calculated as follows : Metabolic Response Baseline/pre treatment FDG PET/CT study will be used to obtain the SUVmax of the lesion-(suv1). FDG PET/CT performed after 3 cycles of neo-adjuvant chemotherapy will be used to obtain (SUV2) of the lesion. page 3 / 5

4 Metabolic response will be calculated as percentage reduction of SUV max (Reduction rate/delta SUV %) by the formula- SUV2-SUV1/SUV1x100. To identify an optimal threshold value of percentage Delta-SUV (reduction rate)capable of separating patients who had an optimal pathologic response (pr) and patients who had a pathologic nonresponse (pnr), a receiver operating characteristic (ROC) analysis will be performed. Reduction of metabolic tumor volume (MTV) and total lesion glycolysis (TLG) will also be calculated using commercially available software.

Histopathological Response Histopathological response will be calculated using tumor regression grade (TRG) TRG Grades 1 & 2 will be grouped as histomorphological responders. page 4 / 5
