Difference in failure patterns of pT3-4N0-3M0 esophageal cancer treated by surgery vs surgery plus radiotherapy

Figure 2 Details of the failure patterns for the two arms. The Y axis represents the number of patients. The most common regions for locoregional recurrence were the supraclavicular and mediastinal lymph nodes (29.5% and 48.3%, respectively) for the surgery cohort. For the S + R arm, supraclavicular lymph nodes (9 of 17 patients) were the most common relapse region after postoperative radiotherapy.
