Background and Purpose : Involvement of supraclavicular lymph nodes (SCL) is
considered distant metastasis for thoracic esophageal carcinoma in AJCC staging system
revised in 1997. We investigated significance of SCL involvement compared to other
regional lymph node involvement.
Materials and Methods : Two-hundred eighty-nine patients with unresectable
esophageal carcinoma were treated with radiation therapy from June of 1979 through
December 1992. Of these patients, 25 were identified having SCL involvement. Survival
rate and relapse patterns were compared with that of mediastinal and perigastric lymph
node positive patients to evaluate prognostic significance of SCL involvement.
Results : Median survival for patients with SCL involvement was 7 months and 2-
and 5-year overall survival rates were 12.0% and 4.0% respectably. Corresponding
features for regional node positive patients were 9 month, 17.0% and 3.8%. There was
no significant difference between two groups. There was also no difference in patterns
of recurrence.
Conclusion : Results of this analysis showed that SCL involvement should be staged
as nodal disease in contrast to present classification of metastatic disease.
