背景
BACKGROUND
The role of aggressive locoregional dissection in the treatment of carcinoma of the thoracic esophagus is controversial. The extent of disease spread for which resection can be performed is not yet fully established.
STUDY DESIGN
Of 230 patients who underwent extended lymph node dissection, including the cervical nodes, the overall hospital mortality rate was 4.8 percent. Recurrent carcinoma was clinically confirmed by periodic follow-up examination with diagnostic imaging in 83 patients. We examined the exact anatomic sites of recurrent lesions and the clinical courses of patients. Recurrence patterns were classified into locoregional, distant, and mixed types.
RESULTS
Recurrence of the carcinoma was locoregional in 35 patients, distant in 38 patients, and mixed in ten patients. The frequency of locoregional recurrence was significantly lower in patients with less than eight positive nodes and in patients without invasion of neighboring organs. Locoregional recurrence in the dissected area was mainly found in the region around the recurrent nerves and the main bronchi. Lymph nodes outside of the dissected area developed recurrence only in cases of markedly advanced disease apart from the abdominal para-aortic nodes. The group with locoregional recurrence and the group with distant recurrence had similar clinical courses over time. In patients in whom recurrent lesions could be treated with resection and adjuvant therapy, the one-year survival rate after recurrence was 83 percent.
CONCLUSIONS
Unless the disease was markedly advanced, systematic lymph node dissection in our procedures yielded good locoregional control. The relatively low rate of distant recurrence with acceptable hospital mortality rates favors an extensive operation. When recurrent lesions were localized macroscopically, surgical removal of the recurrent lesions offered good palliation.
