Radiotherapy for carcinoma of the esophagus in patients aged eighty or older.

Abstract

Between 1980 and 1988, 206 patients with esophageal cancer were treated initially with radiotherapy. The patients were classified into three groups according to age. Ninety-four patients aged 43-69 years comprised Group A, 83 patients aged 70-79 years comprised Group B, and 29 patients aged 80-86 years comprised Group C. There were no statistically significant differences in background factors between Groups A, B, and C, except for the sex ratio. The male:female ratio was 7.5:1 in Group A, 3.9:1 in Group B, and 1.9:1 in Group C, with the difference between Groups A and C being statistically significant (p less than 0.05). High-dose-rate intracavitary irradiation (HDRII) with or without external irradiation (EI) was performed in 64%, 69%, and 83% of the patients from Groups A, B, and C, respectively. Patients in Groups A, B, and C achieved CR in 23%, 24%, and 34% of cases following radiotherapy. Two- and 5-year survival rates were 16.7% and 6.7% in Group A, 17.2% and 6.0% in Group B, and 27.1% and 20.3% in Group C. No significant differences were found in the patterns of failure and in the radiation-induced injuries between the three groups. Our data suggested that radiotherapy was the treatment of first choice for patients 80 years old and older.
