Purpose : The incidence of esophageal carcinoma is increasing. Radical surgery is the
treatment of choice, but large proportion of the esophageal cancer patients are with
unresectable disease at the time of initial diagnosis, so radiation therapy has been the
major treatment modality. We carried out retrospective analysis to see the outcome and
prognostic factors of radiation therapy alone for esophageal carcinoma.
Methods and Materials : From June of 1979 through December 1992, 289 patients with
esophageal carcinoma were treated with radiation therapy alone at Department of
Therapeutic Radiology, Seoul National University Hospital. Of these patients, 84 patients
were excluded as they were ineligible for the current analyses. Twenty-two patients
had distant metastasis other than supraclavicular lymph node metastasis, 52 patients
received fess than 45 Gy, and 10 patient were lost from follow-up. Therefore 205
patients constituted the base population of this study. According to AJCC staging
system. there were 2 patients with stage ¥°, 104 with stage ¥±A, 26 with stage ¥±B, 48
with stage ¥², and 25 with stage ¥³. Radiation dose ranged from 4500 cGy to 6980 cGy
with median dose of 5940 cGy. Follow-up period of the alive patients ranged from 77 to
180 months.
Results : The Median survival period of all the patients was 11 months and the 2-,
5-, and 10-year overall survival rates were 22.4%, 10.2% and 5.3%, respectively. Most
of the failures were local recurrences. Of 169 failures, 134 had local failure as a
component and 111 had local recurrence only. The Lymph node was most common
distant metastatic site and the next was the lung. The stage, T-stage, N-stage,
functional status, tumor size, and aim of treatment were statistically significant
prognostic factors for survival by univariate analyses But only tumor size and N-stage
were significant by multivariate analyses.
Conclusion : We could get 10.2% of 5 years survival rate and 5.3% of 10 year
survival rate with radiation therapy alone. The size of tumor and N-stage were
statistically significant prognostic factors for survival on multivariate analyses.
