Intraluminal high dose rate brachytherapy combined with external radiotherapy in the treatment of oesophageal cancer.
Twenty eight patients with previously untreated oesophageal carcinoma without distant metastases were divided into two groups: Group A consisted of 18 pts. treated with conventional external radiotherapy only. Another group of 10 pts. (Group B) received treatment with external beam irradiation with further high dose rate intraluminal brachytherapy up to a dose of 4-12 Gy delivered in 2-3 sessions of 4 Gy (one session a week). All pts. were evaluated clinically, radiologically and endoscopically every 3 months. At the end of treatment there was a marked difference in relief of dysphagia (39% in Group A vs. 90% in Group B), local control (56.7% in Group A vs. 100% in Group B) and time to progression of dysphagia (20.8 weeks in Group A vs. 67.7 weeks in Group B). No marked difference was observed in overall survival. The complication rate was low in both groups and major complications were observed in pts. treated with external radiotherapy alone (two fistulas). The association of external beam and intraluminal radiotherapy can give a better local control of the disease, improving the quality of life.
