Abstract

The results are reported of HDR intracavitary brachytherapy in 134 esophageal carcinoma patients (110 men and 24 women) treated in 10 Italian centers. Forty-one patients received radical treatment and brachytherapy was often combined with external irradiation and/or chemotherapy. Clinical response rates follow: 56% complete remissions, 34% partial remissions, 10% no response/disease progression and not assessed. Ninety-three patients underwent palliative treatment: dysphagia was reduced in 80% of them and pain was reduced in 71% of them. Treatment-induced esophageal damage consisted in G3-G4 esophagitis (5% of patients), strictures (10%) and fistulas (3%). Complication rates were correlated with fraction dose (9.5% complications for fraction doses < 500 cGy, 20% with doses ranging 500-800 cGy and 38% with fraction doses > 800 cGy). Moreover, the esophagus was more severely injured when small tubes were used (24% with tubes phi < 2 mm, 19% with tubes phi 2-6 mm and 5% with tubes phi > 6 mm). When external irradiation was combined with brachytherapy, dysphagia was more relieved than with brachytherapy alone (89% vs. 71%), with no increase in complication rates. Also the chemotherapy-brachytherapy combination improved swallowing m...Continue Reading
