Comparison tests were performed with Student’s Frequencies were described as number and percentage of total. Comparison was performed with Chi-square tests; for variables with multiple categories additional testing within groups was performed with Bonferroni correction.

Binary logistic regression techniques were used to assess predictors for an adequate D2 lymphadenectomy as determined by the pathologist.
