[Evaluation of the long-term survival rate of thoracic esophageal cancer].
The 5-year survival rate of 906 cases of thoracic esophageal cancer was 23%. Related to sex distribution, it was significantly better in women. Age distribution and location of cancer had no particular correlation to the 5-year survival rate. It increased in the length of the filling defect less than 6 cm and reduced when the length exceeded 10 cm. The 5-year survival rate of the cases a0 was much better than those a1, a2 and a3. That of the cases a3 was much worse than those not only a0 but also a1 and a2. The relation between lymph node metastasis and the 5-year survival rate was shown as follows; the 5-year survival rate of n(-) cases was extremely superior to that of n(+) cases and that of n3(+) and n4(+) cases was worse than that of n1(+) and n2(+) cases. The 5-year survival rate of the cases of stage IV was quite poor. There was found a significant difference between the curative resection group of C II and C III, and the non-curative resection group of CO and CI. The 5-year survival in the cases of squamous cell carcinoma of the well differentiated type was better than that in those of squamous cell carcinoma of the moderately and poorly differentiated types. That of the cases of adenocarcinoma was good, though the number of cases was not so many.
