Although a two-stage approach is often selected due to the technical complexity and invasiveness of simultaneous surgery, both tumors in this case were advanced, and a single-stage resection was considered the most appropriate option to avoid losing the opportunity for curative treatment. The postoperative course was complicated by anastomotic leakage, which was managed conservatively;however, early recurrence of esophageal cancer occurred, followed by multiple brain metastases from small cell lung carcinoma. These recurrences may have been related to limited mediastinal lymph node dissection, performed to preserve bronchial blood flow, and to the delayed initiation of adjuvant therapy due to treatment for esophageal recurrence.
