[The multimodality therapy of advanced inoperable esophageal carcinoma. A retrospective analysis].
BACKGROUND
The records of 161 patients with inoperable esophageal carcinoma were reviewed to determine the influence of concurrent radiochemotherapy and brachytherapy on overall survival.


METHODS
From 1984 to 1999 161 patients suffering from advanced esophageal carcinoma Stage II to IV were treated with radiotherapy alone (131) or radiochemotherapy (30). In 48 patients additional brachytherapy was given. Median follow-up was 8 months (1 to 64 months), the median external beam doses was 51 Gy (18 to 66.6 Gy) and the median brachytherapy dose was 10 Gy (4 to 25 Gy). Chemotherapy consisted of cisplatin and 5-fluorouracil.


RESULTS
Median survival for all patients was 10 months, 3-year survival rate 13% and the 5-year survival 5.2%. In univariate analysis the best results were achieved by concurrent radiochemotherapy with a median overall survival of 13 months, a 4-year survival of 18% (p = 0.0368), the combination of external radiotherapy and additional brachytherapy with a median overall survival of 14 months, a 4-year survival of 12.2% (p = 0.0008). After combination of concurrent radiochemotherapy and brachytherapy the 2-year survival rate is 58%. Multivariate analysis revealed simultaneous radiochemotherapy, external beam dose and additional brachytherapy as prognostic factors. Combination of concurrent radiochemotherapy and brachytherapy was possible without significant increase of local toxicity.


CONCLUSIONS
Our retrospective analysis demonstrates that concurrent radiochemotherapy and additional brachytherapy are effective treatment schedules without significant increase of toxicity and may improve overall survival of patients with inoperable carcinoma of the esophagus. According to the results of this retrospective study, it would be appropriate to conduct a randomized trial to evaluate the benefit of combination of concurrent radiochemotherapy and brachytherapy.
