Abstract
Esophagogastric junction (EGJ) carcinomas often require access to two compartments of the body for good margin and lymphadenectomy. Whether it is required to do so in all patients is debatable. We analyzed outcomes of patients who underwent surgeries for EGJ carcinomas in terms of margin status and survival. This is a retrospective analysis of a prospectively maintained database of patients with EGJ adenocarcinomas operated between January 2014 and December 2016. Type of surgery performed and its impact on margin status and survival were assessed. Follow-up was for a minimum of 5 years. Ninety-four patients with EGJ carcinomas were operated on during the study period. Eight (8.51%) had involved proximal margin, and 2 of these had positive distal margin also. None had distal margin alone involved. Seventeen (18.09%) and 5 (5.32%) had a close proximal and distal margin, respectively. Radial margin was close/involved in 6 (6.38%) patients. Five-year overall survival and disease-free survival for the cohort was 38% and 30.8%, respectively. Proximal gastrectomy had a higher proximal margin positivity. Positive proximal or distal margin and a close/involved radial margin were detrimental to disease free survival and overall survival. Proximal gastrectomy is associated with a higher likelihood of proximal margin positivity. Positive margin leads to lower survival. Whether involvement of margins is just a surrogate marker of aggressive tumor or is an error in assessing extent tumor needs to be studied. Large-scale prospective studies in this regard are desirable.
