Radiation Schedules for Palliation in Carcinoma Esophagus.

ABSTRACT

This study was undertaken to compare the three different radiation schedules for their efficacy in symptom relief, dysphagia free survival and radiation morbidity (if any), in carcinoma oesophagus. A total of 116 inoperable patients were prospectively randomized to three different arms of radiation. Arm-A received external beam radiation (EBRT) to a dose of 30Gy/10 #/2 weeks along with two sessions of intraluminal brachytherapy (ILBT), 600cGy each, one week apart, after a gap of two weeks from EBRT. Arm-B received only EBRT to a dose of 30Gy/10 #/2 weeks. Arm-C received EBRT to a dose of 20Gy/5#/1week without brachytherapy. The age of the patients ranged from 30 - 70 years. Improvement in dysphagia was seen in 76% of patients in Arm-A, 56% in Arm-B & 54% in Arm-C at 1 month. The dysphagia progression free survival was 10.6+0.6 months in Arm-A, 9.8+0.8 months in Arm-B and 9.9+0.6 months in Arm-C respectively. Grade 1 & 2 acute radiation toxicity was seen in 50% of patients in Arm-A, 55% patients in Arm-B & 30% patients in Arm-C. It is concluded that all the three radiation schedules achieved good palliation with similar dysphagia free survival.
