Report on the annual meeting

“ANALYSIS OF THERAPY AND PROGNOSIS OF ESOPHAGEAL CARCINOMA RELATED TO THE TUMOR TYPE”

The relationship of the tumor type and the prognosis of 361 esophageal carcinoma was investigated, and indications of the therapy are discussed. Five year survivors are found only among the patients undergone radical resection in wide sense (CI, Ⅱ, Ⅲ). According to the esophagogram, possibility of radical operation more correlates to the tumor length rather than the tumor type. Radicality is seldom expected in tumors longer than 7 cm in length. Radical operation can be less expected in Iu or Im cases, and in males. When patients were treated with radical operation, 5-year survival rate is closely related to the lymph node spread, the depth of wall invasion and the tumor length. Five year survival more than 30% can be expected, when the tumor length is less than 5 cm in funnel-shaped and spiral type, and 9 cm in serrated type. Macroscopic types (localized, intermediate or infiltrating margin) and histological types are not relevant to the prognosis. Skip lesions indicate grave prognosis of usually less than 1 year. In such cases, more intensive adjuvant therapy is necessary pre- and post-operatively. After radical resection, supraclaviculal and upper mediastinal lymph nodes are liable sites of recurrence, especially in the cases of thoracic esophageal carcinoma. T-shaped radiation is preferable after surgery.
